    Finally getting around to hooking jp my holding tank to my desuperheater. I believe I read in the instructions that waterfurnace does not want you to use shark bite fittings to attach to the desuperheater.

    Is there a reason why? Or is it ok? I have no experience sweating pipes so pex would be much easier for me.

    I heard copper is recommended to connect the DSH to the buffer tank, to avoid the possibility of PEX rupturing if something fails and the DSH water gets too hot.

    Ah ok. I had seen other posts of people using them thats why I was wondering. I will have to figure out how to sweat pipes then

    IIRC, SharkBite fittings are rated to 200 degrees F and 200 psi. I'd feel safer with those than a sweat fitting if you are just learning how to solder pipes.

    My system is plumbed in with shark bites and PEX. No issues to date, 10yrs old!
