How to convert from copper pipes to pvc pipes?

Sure can, cut out the section you want to replace and replace it with CPVC plastic pipe. Connections can be made with sharkbite fittings available at Lowes, Home Depot, etc.

Shark-bite fittings will work and you can use PEX or CPVC You must bevel the inner and outer edges of the pipe so it doesn't cut the o-rings

do not bry the shark-bite in the ground or concrete

do not use the shark-bit inside a wall without an access panel as they do tend to leak after a few years .

Compression fittings will work on copper and CPVC

PVC is for potable water but not for hot water

Copper To Cpvc

They make conversion pieces. You just solder a threaded female or male end and then use the opposite threaded piece for the pvc end and just wrap teflon on whichever side the male threads are on.

why do you need to convert to pvc? Repairing copper is not hard. Just takes a bit of practice soldering. Need a good cleaning brush, a flux application brush, some solder and a good torch that gets pretty hot (like mapp). Its all about NOT touching the part you wish to solder with any part of your body after cleaning it as acids that humans produce actually are corrosive to it and may leak in time. You only need a ring inside of the joint with solder, not a big glob outside.

If you are converting though.......a threaded male to female works or threaded female to male works too. You are basically taking straight pipe and adding a threaded fitting, using teflon and then threading the pvc end into it.

you can get a compression fitting to go from copper to CPVC, dont use the white pvc, its not rated for potable water. use the yellowish CPVC,it is for potable water. you cant just use dome rubber thingy, you have to either solder a fitting on the copper or use a compression fitting. i would tell you exactly what fittings but if you cant solder you wont understand what the fittings are. tell the guy at home depot what you want to do and he will get you what you need. all home depots must have a master plumber on staff, its their new policy.

Go talk to your local hardware store. They are alot more helpful than the "big guys". You should think twice before chaning out the copper. The copper is stronger & cleaner than PVC.
