Step 13: Cut the PEX Pipe
Leaving extra pipe, cut the PEX so you can feed it back through the wall.
Use a mallet to ensure the PEX hasn't popped out of the track.
Tip: Run air or water through the system to check for leaks before installing the finished floor.
Step 14: Connect Radiant Block to the Supply
The radiant mixing block ties into the water heater. The feed and return from the radiant block will go into two ports and is connected to the supply, which comes from the water heater.
Step 15: Attach Adaptor to Heat Loop Port
Remove the control panel and the cover. Use a threaded male adaptor coated with Teflon paste, and screw into the radiant heat loop port on the pump.
Step 16: Connect PEX and Threaded Adaptors
Add Teflon paste to the threaded 3/8-inch PEX adaptor, and connect to the threaded male adaptor.
