ReplyCan you is a good question. The air handler is yours but the piping is the buildings. This question must be answered by The Building.

I live in a townhome community built in the 1960s that has a central boiler/chiller for the heating/cooling of each unit. I need to move the supply/return lines to my upstairs air handler due to some remodeling of the unit. Can I use Pex piping for the new lines or do I have to go back with copper lines?

Apologies if my question wasn't clear. Anything within the 4 walls of my 2-story unit is my responsibility to maintain. I can put in whatever I choose. I'm trying to find out if Pex can be used in a hydronic system like I mentioned above. If Pex is a good substitute for the original copper pipe, I'm confident I can move the lines myself. If I have to go back with copper I will need to have a plumber do the repair.
Just looking for additional opinions as I've been given conflicting info to this point.

I questioning "You Can". The equipment and supply and return lines on your side of the shut off is your responsibilities but by a licensed contractor.
Pex can be used but it must be specific for the job. These are all questions you should be asking your contractor.

If PEX is used, it must be O2 barrier pex.
This is really not something a HO should attempt. What if the valves don't hold? Or there's glycol in the system? What if it gets air bound? Do you know how to purge it?
Hydronics is a closed system, not like open potable water lines. It really should be left for a pro.

Point to ponder for the OP. How much liability insurance do you carry in case something that you do causes damage to your neighbors homes........ say 5 years down the road?
The last water leak damage job I was on ended up being $85,000.00 because one line leaked and half the house had to be gutted to fix the moisture damage. Just saying.
Use the biggest hammer you like, pounding a square peg into a round hole does not equal a proper fit.
