Capping CPVC pipe with CPVC cap

I will be removing a bath tub that does not get used. I plan on cutting the pipes which are CPVC and capping with CPVC caps. Is this fine or do I need something stronger for the water pressure?

Threaded caps would be fine. This way if you ever wanted to reconnect a faucet... you'd be all set.

Pj's suggestion, while valid, won't help on that installation because you can't get those threaded adapters loose. Just cut the piping at a convenient point and following the instructions on the can of CPVC solvent cement glue on the caps. You may, or may not, need to either lightly sandpaper the pipe and cap joining surfaces or use a special primer before using the cement. (I haven't used any CPVC in almost forty years.) If you ever want to re-use the piping then simply cut off the caps and use couplers to extend the piping or threaded adapters or whatever works.

I had thought those were nuts on the faucet but after enlarging the picture I see they are soldered on fittings to adapt to CPVC. No way to get the valve out.

I was considering trying to loosen the nuts and cap then that way but you saved me from eating my time on that. Just wanted to make sure capping with a 28 cents CPVC cap was safe or if I needed something more heavy duty.

I was thinking the same thing as you after I posted this but I would have found out it wouldn't work eventually. That's for the help.

As long as the cap is properly sized and glued in place there won't be any problems. No different than a PVC cap, just different materials and glue.

I agree with the other guys about the cap Ö

and in case you are wondering, the molecular bonding at the cemented joint is such that the joint is just as strong as the pipe itself. That surprised me but Iím about 100% sure thatís true. So those caps wouldnít be popping off any time soon.
