My new-to-me trailer is plumbed with black plastic 3/8" lines and compression fittings. What is this material--ABS?
I'm going to redo most of the plumbing with PEX. Are the old plastic lines compatible with PEX fittings and crimp rings?
The water heater is bypassed, and has plastic 1/2" MPT X 3/8" compression elbows screwed in to the 1/2" metal FPT connections on the water heater. Are these plastic fittings OK, or is this just someone's quick bypass?

I doubt the plastic lines are very good after all these years and am not sure crimp rings will work. Maybe replace all with pex? There are lots of plastic fittings; some better than others. Do you have any photos?

Highly doubt it's ABS. Probably black poly tubing. It won't have the same material characteristics as pex.

Thanks for the replys. vikx, you're right, it's probably best to replace all with PEX.

Ask and ye shall receive. Here's a pic. Might this be original plumbing in this 1976 trailer, or is a this a redo? I know a lot can happen in 43 years!  |

It is poly, at least I think it is. If it's not leaking, you could keep it. The fittings are harder plastic but the lines are flexible, which helps against freezing. I use translucent 3/8 poly tubing in my vintage trailers and am very happy with the ease of installation. However, you're going to have hot water, so Pex is much better.
