Relocate zone manifolds

[Daniel Collick]

I’ll preface this post with the following information:
-I am not an HVAC tech, just a WA State PL01 with a little over 20 years primarily domestic waste & water pipe systems.
-for this little remodel, the contractor could not find anyone willing to show up to relocate these manifolds.
-since we were doing the plumbing and I thought it’d be an appropriate challenge, I volunteered to try and do this so everyone could move forward.
-supply & return, as well as everything in the slab, is all 5/8” Wirsbo
-we ordered the 5/8” expansion head, rings, couplings, pipe, and bend supports and away I went
-never wired actuators before but I made sense of it and reconnected it like it was.
-no thermostat for me to simulate a call for heat.
-unfortunately instead of the 3 hours I told my boss it’d take, it was closer to 7.5 after turning on the boiler and restoring supply/return pressure, etc…
-Anyone have some constructive criticism or should I just stay in my lane next time? I imagine stacking the manifolds so tightly is not ideal, but you can see what I had to work with.

Need a few pics of the boiler and pumps. Raising the floor? Have radiate floor heat? What will be the floor covering?

This is not a new zone. Radiant floor heat is existing. Those four bend supports are located directly below the previous location of the supply/return manifolds, so the in floor heat piping is unchanged. The floor was raised to accommodate the waste piping to avoid removing the slab. Essentially, all I did was cut the existing manifolds out, move them to the new wall, and then reconnect the existing supply/return to the manifolds, and the in floor supply/returns, and lastly reconnect the existing 8 wire boiler controls. Didn’t change anything at the boiler.

Obviously, the new raised floor will not have the radiant heating, but the remainder of the room/slab above which the bathroom is framed will retain its existing radiant heating.
