Can I change this copper line to PVC?

[jonwb1]

Hi... got a leak coming from one of my copper elbows on the return filter line. I'm wondering if I HAVE to use copper to replace it, or can I run 1.5" PVC pipe with new fittings? The return coming up from the ground is copper so I'd have to find a "copper to PVC" elbow. Otherwise, any reason not to go PVC with this setup?

Thanks

There's no reason you can't replace that with PVC. I can't see where ti comes through the slab, but you should be able to get a compression coupling that will transition between the two.

When my 30-year-old copper pipes started leaking, I figured one leak is just the beginning. I had my pad jackhammered and all the copper replaced with PVC. The underground part was already PVC. Something to consider.

Ok then, thanks.

Yes it's copper coming through the slab so a compression fitting sounds good. The original system is probably 30 years old and they ironically used 2" PVC on the incoming lines coming through the same slab. Weird?

What heater do you have?

If the output is hot, you want some heat resistant piping coming out, especially if the pump turns off while the heater is on.

At a minimum, you want to use CPVC and CPVC glue.

Ideally, you would have the heater turn off about 10 minutes before the heater turns off.

Thanks but we don't have a heater.

We have a blue Coverstar retractable cover that heats the water sufficiently during the summer here in California. We're not year long swimmers. Thanks for the heads-up though
