The pursuing summary notes about fuzz and other types of building piping are from Carson Dunlop Associates' Home Source Book, used with permission:
Copper piping has been used extensively since the early 1950s for supply lines from the city main to the house too as for in-building water supply and drain piping.
Copper water supplying piping is typically 1/2 or 3/4 inch diam. Copper piping is typically 1/2 or 3/4 inch diameter. Copper piping has soldered connections and the walls of the pipe are dilutant than galvanized steel. Bull piping has soldered connections and the walls of the pipe are thinner than galvanized nerve.
From 1950 to 1970, 1/2-inch diameter pipage was misused commonly for residential construction water supply pipes. After 1970, 3/4-in diam copper color service piping has been more common for building water supply piping.
Properties of Copper Pipe Types:
K, L, M, DWV, ACR, and Other Types of Copper Pipes used in Buildigns: life expectancy, sizes, thickness, durability & uses
The life expectancy of copper pipage is dependent on water conditions.
In many areas, its spirit expectancy is indefinite. In harsh caustic water or corrosive soil conditions, it may flush it within 20 years or even less.
Occasionally manufacturing defects likewise result in early failure of copper building piping.

Dimensions, Sizes, Thickensses, Lengths of Copper Piping
How is Copper Steaming Sold-out: lengths, diameters
Copper piping is sold in nominal or measure sizes in vertical lengths of 12 foot. 18 ft. or 20 foot. from 1/4" diameter clear up to 12-inches in diameter, contingent on the copper type, thickness, grade, and intended application. Bull piping from 1/4" up to 2-inch in diam is also oversubscribed in coils of 45' up to 100 ft. depending on the pipe diameter.
What is the Relationship Between Nominal Copper Pipe Size up and its Actual Physiological Sized?
Plumbing system Copper
Cu pipage discussed here and misused for plumbing is 1/8" big in diam than its language unit OD or outside diameter.
Object lesson:
1/2" Copper pipe
- 1/2" copper pipe nominal size of it = 1/2"
- 1/2" atomic number 29 pipe actual OD or Outer Diam = 5/8" (that's 1/8" large than nominal size)
- 1/2" copper pipe actual ID Beaver State Inside Diameter = 0.528" for Typewrite K copper
Note that L and M copper pipes or tubing differ in ID and rampart thickness:
1/2" Typecast L copper tubing will undergo an actual ID = 0.545"
1/2" Type M copper tubing will have an actual Idaho = 0.569"
So a 1/2" copper pipe will actually measure 5/8" in thickness. The actual internal diameter of a copper tobacco pipe will change conditional the thickness of the bagpipe wall, tied though these outside dimensions remain the very.
Copper Tubing Wall Thicknesses
Copper tube wall thicknesses vary by tube type.
Type K copper tube: thickest wall section, put-upon therefore in more-demanding applications such As richly force per unit area, buried, harsh environments
Type L copper tubing: thinner walls than Type K, residential & commercial water system pipiong

Unlike copper used for plumbing (above), copper tubing used for HVACR (heating, ventilating, send conditioning &adenosine monophosphate; refrigeration systems), is sold in sizes that correspond to the actual outside diameter of the tubing - see the dimensions given just above for common sizes and flexible overstuffed copper ACR tube dimensions.
What are the Standards for Copper Piping Sizes & Thickness
The copper cognitive content of copper piping meeting the ASTM standards below is virtually pure copper - or 99.9% Cu. The copper is shiny when purchased, typically having had some exterior or indoor surface oxidants cleaned off victimization phosphorous. If you hear reference to DHP copper or C122 coppeer, this is the cartesian product being represented.
The four most-germane standards for copper pipage thickness and dimensions calculate on the intended application and manipulation and are listed as follows:
- ASTM Standard Classifications B-698 encompasses six plumbing pipe (or "pipe") standards including ASTM-B88.
- Type K copper and Type L and M copper pipes are governed by Standard: ASTM B-88
- Type DWV copper piping is governed by Standard: ASTM B-306. This standard also applies to copper pipes exploited in solar power and other HVAC applicaitons.
- Type ACR fuzz piping intended for use in air conditioner and refrigeration sytsems and likewise for gas or LP gasoline (LPG gas) is governed by Standard: ASTM-B-280. [K, L, or M Copper tubing is non allowed for gas statistical distribution.]
- Type OXY/MED copper piping intened for utilize in medical gas applications is governed by Standard: ASTM B-819

- Home inspection report, plumbing section.
As you just bought the put up a skillful place to start would equal with your home inspection reputation. What did your inspector say about the condition of the building plumbing?
Home inspection standards want that the inspector identify the types of plumbing mateirals exploited in the building, place leaks or necessary repairs, particularly costly ones that can atomic number 4 discovered by optic inspection so much as unsound fittings or a piping material known for failures, and also that the inspector observe unsafe conditdions such as the mien of lead weewe provision pipes

Close let's look at functional clues such as poor flow or pressure at fixtures, or slow Oregon abuzz dreams.
- Direct visual clues of circumstance of supply & drain pipage
Start where water enters your building and abide by all of the visible, physically accessible pipes that you can, in order to anticipate the materials that were utilised and the status of the pipe.
Look not only for leaks operating theatre corrosion at joints and connectors but also for signs of pitting, perforation, at runs of piping equally cured.

Compressing Fittings for Copper Tubing Connections
Negotiable copper tube is usually connected to extra tubing sections or to other plumbing fittings by either compression fittings Oregon flare fittings, depending connected the application.
For example, compression fittings (exposure at left, from Wikipedia) are sometimes misused on copper irrigate piping where soldering is difficult operating theater inconvenient, merely these are not used on copper gas or oil lines where flare fittings Crataegus laevigata beryllium practical instead.
Flare fittings and compression fittings are well-meant for expend on squeezable-temper copper piping and tubing. In addition to flare and compression fittings there are also other physical science connectors that now work with soft or semihard atomic number 29 that do non require soldering.
Catch out: compression fittings are really convenient and easy to install on copper pipes operating theater copper tubing, but if you fail to de-burr a freshly-cut copper pipe or underground, properly ream out the interior opening, or if you over-tighten the coupling during installation you may crack the brass instrument or atomic number 29 ring, major to leaks at the connector.
Compaction fittings are in use with K-copper. K copper pipes and tube can also be joined surgery connected victimisation flare fittings and sweat fittings discussed below.
Also see COMPRESSION THREAD vs PIPE THREAD
Flare Fittings Victimised for On the table Copper Tubing Connections
Flare fittings used on flexible cop piping and their leaks and defects are discussed
at GAS LEAK DETECTION, L-P / Nanogram
and GAS PIPING CLEARANCES, CODES & DEFECTS.
Using a peculiar flaring tool the soft copper tubing or piping is actually spread open or flared at its end in order to mate with the female end of the flare fitting connective shown in our photograph.
Watch out: defects in flare fittings used on flexible copper tubing stool result in gas leaks KO'd of accelerator piping, and in the case of oil piping such as for fueled heaters, flare fitting defects result in some oil leaks out of the system and tune leaks into the system.
Melodic phrase leaks into oil piping in move around lead to improper oil burner operation and even possibly dangerous conditions. Flare fitting defects include:
- Improperly made tubing flares that are besides small
- Improperly made copper tubing flares that are cracked
- Scratches surgery gouges on the copper tubing flare or on the brass flare fitting (shown in our pic, above left)
Seat and flare fittings are permitted on K and L copper color. L-P blow tubing. These fittings are non victimized on refrigeration equipment.
Swaged Copper Tube Joints
Soft copper tubing tail end also be joined away exploitation a swaging creature that expands the open end of i of the tubes to be joined so that its mate can be inseted into the enlarged opening, and the result sealed by soldering or brazing.
This is a common subroutine when using air travel conditioning refrigerant tubing because of the high pressures that may be convoluted and the need for extra strong resistance to leaks in piping that may be subject to wide temperature variations as well as mechanical vibration.
Our photo (chromatic pointer in photo at left) illustrates swaged fittings happening copper tubing - you can see the swaged tube joints at the left and right ends of the gray filter-dryer connected this air conditioning high infrigidation line exiting at the bottom of a compressor-condenser unit.
A swaging tool is inserted into the end of the copper subway and hammered inward.
Atomic number 3 the properly-calibrated diameter of the swaging tool is forced into the fuzz tube, the copper expands to just the right sized to accept the outermost diameter of the mating section to comprise inserted.
For example, if we are swage fitting two sections a 3/8" nominal diameter copper tube together, the swaging instrument will enlarge the receiving copper tube section so that its inside diameter will go for the 3/8" outer diameter of the un-treaterd tube to be joined.
Usually we work the swaging process connected tubing at ambient temperatures simply some procedures call for pre-heating the copper to make over it easier to expand.
Lookout out: Delicate copper tube is drawn copper while hard tube is annealed. It's easy to upset fit soft copper, usually. But if copper tubing has been repeatedly bent, that march may possess treated the copper slightly, making it difficult to form either a flash fitting operating theater a swaged fitting without bully the tubing.
Copper tubing may too become crack prone when exposed to mercaptan Beaver State other odorants in LP gas or natural gas. Moisture exposure and even close to types of solder also can move its susceptability to not bad later. For these reasons bull tube is not allowed for lifelike gas distribution.
Fittings Allowed for Types of Cop Pipes &adenylic acid; Tubing
"Sweat" fittings or "soldered fittings" for copper piping relate to the traditional and perhaps near widely-used method for act copper suppy and drain tobacco pipe connections, caisson diseas, elbows, valves, and similar fittings in buildings.
Depending happening the association required, a coupling (straight connection), 90 arcdegree ell, 45 degree ell, tee, and smooth fittings that marry copper pipes of different diameters are soldered to the copper tubing or pipe to spend a penny the connective.

How to Tell Brass Urine Pipes from Copper Piping
Watch out: on older buildings brass water supply piping English hawthorn have been used, and may be at or near the destruction of its useful life
. It can be tricky to tell the difference between nerve water cater piping and copper water supply piping if you are not experienced with these materials, as their colours are similar, particularly when some types of steaming have become an oxidized brownish tinge with eld.

Brass water supply pipe, unlike pig, is a thicker bodily that is commonly joined by threaded fittings of the assonant size and pipe draw specifications (NPT) As iron and galvanized iron pipe.
Usually, brass piping is also so rigid that it is not bendable. Or not really bendable in any case.

Copper Append or Drain Pipe Pinhole Leaks: cause, bring around, prevention
Water chemistry, Electrical Grounding, Netural Wiring, &adenylic acid; Copper Pipe Pinholing &adenylic acid; Leaks
In a edifice where leaks are found recurrent in copper piping there are several assertable explanations including these possible causes for the pinhole leak out in copper water piping under a building concrete take aback slab as well as at other locations:
- Imperfect copper piping: the pipe could have been malfunctioning from day one, e.g. with thin spots operating room damage that corrode through and escape
- Unbecoming eccentric of copper piping Crataegus laevigata have been installed - see the fuzz steaming types and applications delineated in the article above.
- Ruptured cop water pipage: the pipe could have been damaged in transport or facility Beaver State even off during the slab swarm
- Irregular electrical prime or neutral wiring: along occasion a bad or improperly-connected physical phenomenon background OR another electrical job can contribute to plumbing system or other pipe corrosion at a building.
In diagnosis continual failures in a ground water sourced air conditioning system that kept blowing stunned a very costly chilling coil for we base that the problem was finally traced to unexpected physical phenomenon currents in the ground system payable to a neutral wiring error in the AC unit's controls.
Ask a licensed electrician check the home's grounding and neutral systems: that they are in good order wired, that the earthing electrodes are properly sized and installed, and that there are atomic number 102 stray currents on the neutral system nor shorts or leaks in the wiring system (an AFCI or GFCI can help notice thee too).
- Aggressive water: the water chemistry itself bum be a source of metal water pipe (and even drain pipe) corrosion.
If the pH is low <6.0, the hardness low generally<50ppm, the alkalinity low generally <40ppm, the water could be considered extremely "soft" and aggressive to the home's metallic plumbing system. If the chlorides are elevated >100ppm this would only compound the problem. The water should be treated to make the water less self-asserting away raising the pH, alkalinity or inclemency. - CT Do.[1]
Summary of the issue round grounding building water piping
Many sources, including the CT Ut have pointed out a aware-standing disagreement &ere; confusion nearly the reasons for grouinding building water supply piping. For instance
AWWA opposes the grounding of exciting systems to pipe systems conveying boozing water to a client's premises. ... AWWA asserts that a body of water utility has no square or indirect responsibility in connection with the installation of water pipe grounding systems or for the maintenance of the wholeness of some grounding attachment or connection made to a water pipe system. [AWWA 5/15/2003] [1]
This statement is a bit of a preliminary prospectus.
Water and much plumbing associations are concerned about building proprietor complaints about metal water supply pipe corroding and leakage that might be traced to Oregon blamed on the electric grounding of those systems.
Want to obviate those complaints the industry, below the aegis of warning that water suppliers can't be responsible the loser of such an electrical ground [a valid caveat] a warning is issued that also gives relief for metal piping leaks caused by a kind of other problems such American Samoa
- irrigate chemistry - see our notes just to a lower place
- defective piping
- improper installations
More pertinent, metal water supply piping is grounded non to provide an electrical found for the construction (we agree completely that water high every bit a ground is unreliable for many reasons, (such Eastern Samoa inclusion of not-conductive plastic piping, diaelectric fittings, water meters, etc).
Metal water high-pitched is bonded to a construction ground system as an important safety precaution to protect construction occupants from burning hazards should active electrical wires or components ejaculate in contact with building piping, faucets, fixtures, etc.
In a decent-wired building, the grounding conductor and soldering organisation do not usually carry current, and would non be blessed for copper tobacco pipe pinholing etc. The grounding system is intended to conduct electrical current only in the event of a fault or hand brake [much as a lightning strike or a hair dryer born into the bathroom tub or sink].

How to Check for Electrical Organization Problems that Corrode Copper H2O Pipes
[For buildings served past private ground water] Should the problem persist and the well water is still blue and it is discovered that the private well's bronze discharge production line has an electrical "foundation" clamp, have them contact a licensed electrician to investigate the situation.
The electrician would check the main circuit panel for a inaccurate, missing or improperly secured "neutral" wire. Helium could also mental test the plumbing to visit if in that respect is any stray AC or District of Columbia topical.
In that location should not be any prevalent, even in milliamps! If on that point is flow, the improperly functioning OR shorted twist/ appliance should be found and repaired. He should also check that the mansion plumbing has a greater resistance (>25 ohms) than the grounding rod(s).
The ground wire to the plumbing system should non be removed As it is mandated in the CT Construction Code but it should non be the primary mail carrier of stray electrical current or potential difference surges to "ground" - Constitution State Do.[1]

Almost likely IT's an oxide of bull caused past corrosion. Take it closely to be indisputable there are no leaks.
Watch impermissible: never "pick" at operating theater probe corroding.The risk is that you convert a small leak into a big emergency leak that requires that you shut down the construction water supply.
Sal:
Follow stunned: Greenness corrosion on a water pipe that is found only around the electrical run aground is deserving more or less further checking: stray electric currents or improper grounding could be causation the corrosion that you see.
Close to Green erosion on copper piping is common and may not necessarily mean a leak is represent. For example we may check corrosion where solder flux ran out around a solder sharing during shriek connections by sweating (copper soldering).
Question: Acid water & bull pipe corrosion/passing water risks
I get a lot of Amytal stains on bathtubs and sinks, which I assume is copper leached from the inside of the copper water-supply piping. I stacked the house about 16 days ago and replaced the water heater few years ago.
Am I at risk of developing pin holes or other damage to the copper plumbing and other equipment, including an electric hot-water heater, steam boiler, and baseboard radiotherapy?
If that's the case, what's the favourite (and cheapest) solution: calcite neutralizer tank, sodium carbonate feeder, Beaver State other?
FYI, copper level was last measured at 0.11 mg/L, well below the MCL of 1.3, so I wear't think there's a health issue. Only I chassis if copper gets leached from the pipes for enough eld, at some point there won't be much pipe left.

What would make the low temperature copper pipes in the house appeared burned or charred. The hot is fine. Just the cold looks this way. Some ideas?

What you discover is normal, provided there are not actual sunburn marks from overheating such as past a soldering torch, and in fact dark or even coloured Cu piping often helps us identify cold vs hot water supply atomic number 29 piping.
Far water piping is seasonally wet by abridgment that in turn over boosts both soiling or dust collection and mild oxidation.
The result is that loosely the bleak water cop piping leave be darker in color than the hot lines.
Wonder: turning the water back connected later on long shut-pile

The water has been close off in a menage with copper plumbing for 2+ years. Are there whatsoever special problems that could equal related to with no water in piping for an drawn-out period?
Question: Water line insurance for leakage or failure - what is pipe life-span
(Jan 29, 2014) Curtis said:
My Clifton NJ house was built in 1952 and I new received a Outdoor Pee Line indemnity policy in the chain mail covering replenishment of the water line should it fail. What is the lifespan for the body of water line? Is this something I should be worried astir?

I'm a little tense about this one Curtis.
At PIPING in BUILDINGS, CLOGS, LEAKS, TYPES - we indeed give life expectancy of diverse building piping materials.
But for your question I'm in disorder:
We don't know the crucial of your water main, the territory corrosivity, nor how the line was installed, nor its length to Wall Street water main, nor its profundity: all of these are significant factors in water note renewal cost and animation expectancy.
I'm also not sure who's selling you this classify of pig-in-a-poke insurance: that is, what class of insurance are we purchasing when the insurer knows null about the property Oregon item being insured?
If I were an underwriter (I'm not qualified to be one, this is just Judgement) I'd embody nervous, especially knowing that a bevy of menage warranty companies marketing to home buyers and home inspectors went belly-up due to the adverse excerption problem.
And I'd want to know about the insurance price and World Health Organization's selling IT. A quick web search turned up Excelsior Insurance as a company selling water damage coverage and potentially a part of Indecorum Mutual group (reputable).
It also sour up something to look into: Insurance Firm On Rarified Ice In Denying Claim, Try Rules
Jan 09, 1988|By Henry Martyn Robert Bruss. - admittedly an old snafu. But a quick search shows rather few legal disputes over collecting on insurance policies issued by the Excelsior Insurance Co. for water price. - Is this the company offering a policy?

Thanks for the response. I have not heard of anyone needing to replace a water main into the house simply suspect information technology must need to be done at some point...The company is HomeServe.

Certainly the lateral or in some parlance "H2O principal" between star sign and street is ultimately replaced on buildings. But depending on variables I cited along with piping cloth and quality, wall heaviness, care of installation, and soil conditions, these lines can last a daylong time.
20-40 years would not be unusual. In the Eastern U.S. where lead entry mains went into homes around 1900 we saw replacements beginning to be more public 50-70 age later.
Question: leaks showing awake in copper pipes, pipes smel soft

Hi Sugar apple;
The answer is ... it depends. On wherefore the pipes are leaking; If the germinal installment used defective copper Operating theatre if the water system is very caustic and then you could be facing an extensive resort.
I would want to know Thomas More about the leaks - where they occurred in the theater, whether they were on hot or stone-cold pipe, and I'd suchlike to envision sharp photos of the leak; ideally you'd cut out 4 inches some the news leak and have someone with experience study the pipage itself -
Beaver State send me photos or a tabor pipe fragment if you equivalent and I can make a forcible exam in our lab (while we have a rhetorical science laborator here I'm not a copper expert but I suspect we can figure out what's going happening by microscopic interrogatory)
