I am building a custom shower which includes multiple heads. My home has 1/2" copper lines but I need to upgrade to 3/4" to handle the extra water flow.

I want to run 3/4" sch 40 pvc in my attic (about 60 ft)and then just let the plumber connect to pvc to the copper at each end. This will save me allot of $$ in labor if I can use PVC to do the run instead of having to run copper and pay a plumber to do it.

Does anyone have any concerns with this method?

Thoughts? Comments Suggestions?

Thanks,

Greg

Hi Greg, The only change I would make is to run CPVC in place of PVC. Just make sure to take off from a 3/4 or 1 inch main and that the pipe and fittings are primed and the proper glue used. Good luck, Tom

What exactly is CPVC? Is it available at local hardware (Lowes, home Depot) stores?

I saw this product online at homedepot.com but it says NOT FOR USE WITH HOT WATER DISTRIBUTION? Is this the right product?

PVC Schedule 40 Solidcore Pipe is Iron Pipe Size (IPS) and conforms to ASTM D 1785 and ASTM D 2665. This means the pipe can be used for either Drain, Waste, and Vent (DWV) or pressure applications. WHEN USED WITH DWV FITTINGS, THE SYSTEM IS NOT INTENDED FOR PRESSURE APPLCATIONS. When using pressure fittings (ASTM D 2466) and pressure applications the operating temperature should not exceed 140 degrees Fahrenheit. NOT FOR USE WITH HOT WATER DISTRIBUTION. **PLASTIC PRODUCTS SHOULD NOT BE USED WITH COMPRESSED AIR OR GASES

ASTM Standard D 1785
Max Working Pressure - 330 PSI
Not for use with Hot Water distribution
Dual Rated Pipe
MFG Brand Name : Charlotte Pipe
MFG Model # : PVC 04007 0600
MFG Part # : PVC 04007 0600
Usage : Drain, Vent And Pressure Piping

CPVC is rated for hot and cold where as pvc is just for cold. It is definitely available at Lowe's or home depot just be sure your glue is for CPVC and not just PVC. For the rest of it follow Speedball's advice and HAPPY PLUMBING. GOOD LUCK, AC

No! What you saw was PVC which is used for cold water only. AC gave you a good rundown on CPVC which is used in both hot and cold water installations. Regards, Tom

And when I brought it up it told me that no information was available. So what else do you wish to know besides PVC's only for cold water while CPVC's for both hot and cold? Is thyere anything else we cam help with? Regards, Tom

Here is a link that does work. CPVC Products Other than CPVC your other option is PEX at about 1/3 the cost of plumbing and easier than CPVC in my eye. With PEX you can make one long run without splices or extra couplings and still snake around corners without cutting.

Where can I find PEX

You can check on Pex by clicking on: Pex Tubing, Oxypex Pex Tubing, Portable Water Pex Tubing
Scroll down on the left hand side for Pex fittings. Good luck, Tom

PEX is a standard plumbing pipe available about every where PVC and CPVC is sold. Home center and plumbing supply will have all of this stuff. You can use PEX fittings or if you don't want to buy/borrow the tools you can use Sharkbite fittings also available at Home centers. Sharkbite will work on PVC and PEX but not CPVC.
