Hi Everyone,

I just recently moved to central Florida and have an 11000 gallon Gunite pool with a DE filter.

Recently, the chlorinator stopped filling with water, and it worked fine when we moved in, but if I go out there everyday and unscrew it until water over flows and re-cap it, it will work fine.

Today, I replaced the chlorinator and the cartridges in the DE filter and still nothing.

If it helps, it is a pentair 320 in line with 3" chlorine tabs and my pump is a purex triton pns plus model 36.

I dont know if it is the check valve, or if there is even one in place, if there is its underground and I cannot see it.


Thanks in advance for your help!
