Using 3/8 PEX and 1/2 PEX on same manifold
Is it possible to mix 3/8 and 1/2 PEX within the same manifold zone. Here is out setup...
We have a zone manifold with four loops. This is for the upstairs with three bedrooms and one bathroom. The bedrooms will be hardwood flooring, using 1/2 PEX staple up from underneath the subfloor with aluminum heat transfer plates. The bathroom is title. We would like to use 3/8 PEX in the bathroom between the subfloor and title. Is it feasible to use 3/8" and 1/2" PEX within the same zone? And if so, do we keep the 3/8" loop the same length as the three other 1/2" loops, or is there a calculation to keep the one 3/8" loop and three 1/2" loops balanced?
