After you've laid out your PEX tubing for a radiant heat system, make sure to pressure test BEFORE you pour your slab to make sure that nothing has punctured or disconnected. You should pressure again DURING the slab pour and then once more AFTER the pour, just to make sure that everything is working properly before you need to rely on that system for heat. The more you pressure test, the more sure you'll be that your radiant heat will keep your home comfortable all winter long.
Pressure test kits as well as PEX Tubing and a variety of other supplies for radiant heat can be found at www.supplyhouse.com
