My system seams to be leaking vacuum pressure. What should I do?
To fix a leaking system, leave the system charged with vacuum pressure and apply a small amount of silicone to each of the brass fittings and gauge where they attach to the PVC caps. If a leak does exist, the vacuum pressure will pull the silicone into the void area causing the leak to seal itself. Also consider applying silicone to the area around the edge of the PVC caps on the pipe. This is a very common area for leaks. After you have applied the silicone, turn the system off and let the air back into the PVC pipe by opening the vacuum valve. Allow the unit to sit overnight so the silicone can cure.
