How To Pressure Test
How do you pressure test your in-floor heating system?

If something happened during installation, PEX pipes can develop leaks, especially under constant high pressure (Luckily the HUG Hydronics In-floor Heating system is a low pressure system), so it behooves the installer, and required by code to check for leaks and repair or replace leaking pex pipes before they lay concrete. They can/should also use the test kit to hold a constant pressure during the concrete pour.
How to pressure test the Pex:
- Install the end cap hose starting at the input side of your first loop with a clamp (All blue hoses should be pushed onto PEX at least ¾” and clamps need to be tightened with pliers) .
- On the return end of your first loop, install a blue hose with clamp.
- Connect the other end of the blue hose to the input side of loop 2 and add a clamp (make sure the blue hose doesn’t kink).
- Add another blue hose with clamps from the return of loop 2 to the input of loop 3.
- Continue this process until all your loops are connected and you have 1 hose at the end without anything connected to it.
- Push the pressure gauge onto the last hose and install a clamp.
- Double check to make sure all your clamps and fittings are tight, secure, and that there are no kinks in any of the blue hoses.
- Add air from 30 to 50PSI. Monitor air for at least 30 minutes. Check local codes.
- If there is a leak you will have to test each loop individually to find the leak. Repair the leak and retest.
