Can you use regular pvc pipe fittings on the grey water line in trailors?

Answer 1

I used to own a business that serviced mobile home warranties.

Unfortunately, youve got a home from a dealer that chose to save a few bucks by using the grey tubing, instead of household type plumbing. I imagine the original fittings have copper bands around them.

Youve got two choices.... you can spend $100 to buy the crimping tool for the copper bands... or you can buy compression fitting joints. Qwest brand fittings and valves are made for this type of plumbing.... you need to know the exact size of your tubing... (most likely, its 5/8") Once you go shopping, you will realize that the fittings and valves for this type of plumbing cost MORE than the conventional plumbing.... so, your home manufacturer has pushed the added cost of maintenance off on to you. You can expect a typical shut off valve in the Qwest brand, to run about $8.... you'd spend half that for any other type.

The lawsuit that one person mentioned above, refers to the OLDER versions of the grey tubing.... NOT the stuff that is used by today's manufacturers. The only reason the lawsuit is still open for claims, is because of the number of older homes still in use.

Just a tip for those shopping for a new home.... whether it be a mobile, modular, etc.... look at the plumbing.... grey tubing, is a low quality home. Stay away from those. Other features to look for are 6inch exterior walls.....with regular studs used on the interior.... Any dealer who tells you that "all load bearing walls are made of 2x4 studs".... is pulling your leg... the only 'load bearing' walls in a manufactured home, are the exterior walls, and the marriage wall, on a double-wide (the wall that runs down the middle of the two halves). Usually, a home that has that kind of description has interior walls that are made of even smaller lumber.... often 1 1/2" square. These are often very bad about allowing sound thru them. There are other tips I could provide about shopping for a quality home, but this isnt the place, hehehe.

O, by the way... not ALL hardware stores carry the Qwest brand of fittings.... you may have to do some shopping.... any mobile home parts dealer, should have them in stock tho.

Good Luck!

Wow I can't believe some of the answers that you have gotten here.They are correct that you should not use PVC pipe it can't handle the heat and I have never seen CPVC used in heating lines,some might say it is ok but I would never use it.Type L copper is generally used for potable water lines and type M is used for heating systems,{ yes type M is thinner walled but the finned tubing is even thinner and a heating system should never get above 30 psi.unlike potable water systems that could have up to 90 psi.] I am not aware of codes that require black iron pipes for heating,sometimes it is used at the boiler for the manifolds but gets quite pricey for the whole system.With that said copper is getting too expensive to do a large system with these days and plastic PEX type tubing is being used all over now and it has a proven track record.However it is a special pipe used for heating,it should be marked for heating systems and not for potable water.Some will be marked Heatpex,Hepex,Hpex.Other companies are now making this type tubing and may have other markings and there is one brand that has a thin layer of Aluminum inside.This tubing when bent will hold the shape that it is bent to.The main difference between regular PEX tubing and a heat PEX is the heat PEX will have an Oxygen barrier in it.The new in floor radiant heating systems use mainly heating PEX tubings both in concrete floors and under regular floors,some of these systems have thousands of feet of tubing if these had to be done in copper or black iron no one could afford to put it in.I would use both copper and heating PEX tubings.Copper at the boiler and some at the base boards and PEX in between.

Answer 5

Water Line Fittings

Answer 6

The gray PVC is Schedule 80 PVC, whereas the white is 40, I believe.
They sell the gray pipe fittings, too, so stick with the gray all the way around.

Answer 7

Have a Plumber Fix It Right Or Suffer More Water Damage,You Really Need To Do Away With The Gray Altogether

Answer 8

You can try but the grey pipe is better off replaced. The lawsuit that has been settled do the failure of grey pipe still has an opening for further claims. It really depends on the year that the pipe was installed.

Answer 9

no you cant use regular PVC fittings on the gray pipe. It takes compression fittings for the gray not couplings or connectors like the white.

Answer 10

No. The gray pipe requires mechanical joints. PVC requires glue joints.
