You cannot use PVC, it will withstand the pressure but not the temperature. Hot water would require nylon or CPVC as Joseph suggested.Forum moderators are not GD employees--we are volunteers and owners presumably just like yourself.

Mike, I have a 2021 Reflection 295RL. I misplaced my drain "cap" and just bought a 2 pack today from my dealer for about $12. I put it on and seem to have tightened it forever and it still is dripping. I was looking tonight for a solution. Question-did you use Teflon tape with your new CPVC cap? I had the same problem last year when it was just off the lot, but got it to stop just by tightening it. Thanks! DavidDavid & Debra

BlueDuck You may need to use tape or paste. On every one I have done, there was some type of sealant.

I just put mine back on a few days ago. I used teflon tape...which is a pain in the **** to put on the nipple with the burner in the way. Works well though, I have no leaks.
Potable water sealant would be easier. There was some remnants of sealer from the factory.
Whoever thought of changing it from a plug to a cap should be fired.2018 Dodge 3500 6.7 Cummins w Aisin and 9 cup holders

I was told by the manufacturers of the fittings that they did not recommend either PVC or CPVC in hot water applications if *threaded fittings* were involved. Cemented applications were fine.
I still bet CPVC would work but I sure hated to take a chance with it inside the storage compartment. If the threads fail due to the heat, and the fitting is on the outside of the trailer, no big deal.2020 Reflection 273MK

The only thing I can think is that the T&P valve may be aluminum bronze or bronze. This would minimize or eliminate the galvanic corrosion issue.
https://en.wikipedia.org/wiki/Aluminium_bronze ApplicationsThe brass fittings are for above-the-waterline use only. 1/8" and 1/4"dia. plugs are offered in both brass and bronze. Due to the difference in nobility between brass and bronze, which can result in galvanic corrosion (and a failure of the fitting), we recommend that you not use these alloys together in saltwater environments. https://www.westmarine.com/buy/seafi...11_332_001_002
I would think if one was using bronze pipe plugs instead of brass it would be OK. I think the T&P are bronze bodies.Joseph

The CPVC (I think) threaded adapter in post 24 has been in place in my water heater for about six years . . . no problems so far.
