I did an inspection on a mobile home the other day. I found they used PVC coming from the main to the home. I reported that PVC is not approved for water distribution. I learned that somewhere but can’t seem to find where. The client is asking for some back-up documentation. Is it correct that PVC is not approved for water distribution? And, Where can I find some back-up, if so

Hi Kevin:
According to the IRC P2904.4.1, PVC piping is acceptable, along with ABS, brass CPVC, copper, PEX-AL-PEX, ductile iron, Galvanized pipe, PE-AL-PE, PE, PVC, and stainless steel.
Since the local codes have final jurisdiction, I would check with the local Plumbing code officer of that area. It is always possible that that area does not permit it.

Kevin,
Basically the IPC says PVC is allowed for water service pipe but must terminate within 5 feet of entering the home. PVC is not allowable for interior water distribution piping (CPVC is, of course, OK). IPC 605.4 & 605.5.
The UPC just says PVC may be used for cold water supply outside the home but not for hot/cold distribution within but I would guess they allow the transition within. UPC 604.1
If it was just the feed from the street to the home (mobile or not) then PVC would normally be allowable. Your AHJ may vary of course

Depends on which version of the code the home was done with. It may not be allowed using current code, but it might not have been built using current code. Just depends on when the area adopts it.
I still find it funny that they don't want PVC for interior, but will take CPVC, when CPVC is know to allow the growth of the bacteria that caused legionaires disease.

Hi. guys
Hope you are all doing fine.
Few comments to this subject:
PE pipe may be used in any water service system,in accordance with the following model codes: BOCA
National Plumbing Code, IAPMO National Plumbing Code, IPC International Plumbing Code, NAPHCC National Standard Plumbing Code, SBCCI Standard Plumbing Code and various state codes.
Verify acceptance and installation of PE piping systems with the local code enforcement authorities having local jurisdiction.
Chlorinated Poly (Vinyl Chloride) (CPVC) is used for potable water distribution, corrosive fluid handling in industry and fire suppression systems.
Industrial CPVC pipe is manufactured by extrusion in sizes from 1/4" to 12" in diameter to Sch 40, Sch80, and SDR.

I’m kinda busy this week, but if you search a little, you will find it when cpvc or pex is used for cold water, or hot water when the hot water isn’t heated enough to kill the bacteria.
I thought it was odd to, and my whole house is piped with cpvc.

Read closely. It’s a mobile home. Normal building codes don’t apply.
