Pressure testing the entire solar system provides for a trouble-free installation and takes only about fifteen minutes. Any
weak PVC glue joint, fittings or pipe, and any improper panel clamp connections, will be evident while the system is put
under 40 to 50 PSI of pressure.
Allow ample time for all glue joints to dry completely. Use this time to wrap up things and to clean up the job site.
Wrap the threads of the (2-
3020-022
) pressure test “T” assembly with Teflon tape. Replace temporarily the vacuum
breaker with the (2-
3020-022
) pressure test “T” assembly. Thread the ½” ball valve and pressure gauge into the
pressure test “T” assembly.

Attach a garden hose to the ½” ball valve. Make sure the ½” ball valve is in the “OFF” position.
Turn the solar system on to allow the pool pump to completely fill the solar system. (If the pool pump is not
operational, shut off the ball valve on the feed line and use the garden hose to fill the system.)
Once the solar system is completely full of water, turn off the pool pump or turn the 3-way valve to bypass the
solar system. Quickly turn off the ball valves on both the feed and return lines.
Turn on the city water to the garden hose and open the ½” ball valve on the pressure test “T” assembly until
the pressure gauge reads 40 to 50 PSI and then turn off the ½” ball valve. Turn off city water.
With the system under pressure, check the whole system for any leaks. A drop in pressure on the pressure
gauge indicates a leak in the system.
If there are leaks, open the ball valve on the return line to relive the pressure. Repair any leaks. Repeat the
pressure testing procedures as needed.
Return
the
system to normal when through with the pressure testing. Be sure to open both ball valves and replace
the pressure test “T” assembly with the vacuum breaker.
