I have some black PVC pipe in the house I am renting. I want to extend the piping (with landlords permission).
Is black PVC the same as white? Can I use regular PVC glue to connect new white PVC to the black?
Thanks...Paul
The only black PVC I have seen is flex. It uses the same glue but I have never seen it in a house - only irrigation systems.
The black is used for drains (sinks toilets)on a lot houses. You can use the same glue, I would try to find some black to use instead of white it is more resitant to contamiaminated water. But if white is all you have it will last a long time.Also the white my not fit.
Good luck,W
The drain pipe if that is what it is is likely ABS and not for water supplies - the only black PVC I could think of is flex.
Kiwi55... how have you determined that the pipe is PVC and not something else.
PVC pipe that is suitable for plumbing supply lines is fairly rigid and thicker walled than the PVC that is black and used for irrigation lines. Supply line PVC is either white or grey; mostly white, the grey is schedule 80. Use schedule 40 for all supply lines.
Let it be noted that PVC is only permitted for COLD water lines. Plastic pipe for HOT water lines must be CPVC. That said I'd use CPVC for both hot and cold as the fittings and glue are different. I don't believe in the multi purpose glues, not when it comes to water pipes under pressure.
I believe the maximum temperature rating of PVC is 120 degrees; it's stamped on all PVC, CPVC pipes. I don't know if ABS is rated for potable water use I don't think so though as it is not as strong as PVC.
It is on the drain system. I've never seen black for sale anywhere.
I guess I'll see if a standard PVC coupler fits, otherwise I'll use a rubber type coupler.

It's rigid like normal PVC and has glued fitting just like normal PVC. It's 1 1/2 dia and on the drain side.

If it's black and in a drain it's ABS.
Different glues.
You should be able to find ABS and all the ABS fittings you need to carry on the extension.
What don said.
Or, use a rubber furnco and couple it to pvc which is suitable for drains, just seldom used.
You should try to use the same as already installed when ever possible.
ABS... I learn something new every day.
I'll look for ABS to complete the job.
Many Thanks...Paul
