Did you do the in floor pex yourself? I'm having trouble getting supply houses to Even return calls. I'm more than capable of buying pex from menards and zip tying it to my rebar....but would really like some advice on how big of spaces to leave between rows....how long of runs to do? I assume 3/4 pex....thanks in advance if you have some insight.!

I used 1/2" pex with 15" or 18" spacing. If you really need exact , I could look up plans tomorrow. I broke the main bay into 3 sections (pours) of 20 x 30 each with a heat loop for each. The loops were brought up thru concrete using plastic conduit sweep 90's to manifolds. Make the turns gentle sweep 180 degree and don't tie snug at top of loop. Send me PM if you want more exact info. That way I will get email alert.
