End of branch/zone piping question

DJDrew

Hello,

Quick question, I think… the end of the branch/zone piping has three hot water radiators. The return line is tee'd, but the supply is set so it is not deadheaded. Is this acceptable? Or should the return be set to mirror the supply? All the radiators are fitted with a TRV.

According to the M2101.7Prohibited tee applications, I think this is satisfactory, but wanted a second opinion.

Thoughts?

I would have piped them both the same as the supply. If they are low flow rates 1- 1.5 gpm it will probably work fine. Simple enough to change, however. Take the guesswork out of the piping.

Add isolators in all the holes, if they aren’t already, to eliminate any squeak potential.

Intplm.

Looks like you have some Mickey Mouse ears in those pipe holes through the studs. That should be ok to help eliminate any squeak.
