TROUBLESHOOTING POOL FILTERS

 

Filters help to keep pools clean and healthy.
Diatomaceous earth (DE) filters, sand filters and
cartridge filters.

Like any product, filters can have various minor

problems that are easily solved provided the user

knows what to do.

 

 

DE Filters
These filters come in a wide variety of sizes and are filled

with a powdery substance that assists in water purification.
If a filter leaks from the bump shaft, then the
O-rings on the bump shaft are worn or broken and must be
replaced.

 

A backwash valve that leaks after you shut it off
needs to be replaced. Until replacement, a plug with an
O-ring can be screwed into the end of the backwash line.

If you press the bump handle up and down and it still feels
loose, then one of the C-rings connected to the bump shaft
is broken or damaged. Both need replacement.

If the filter lets diatomaceous earth powder back into the
pool, then the filter grids, filter fingers, filter manifold or
multiport section of your filter may have a crack or rip.
If no damage is found, check the tube sheets

through which the filter fingers slide.
Cracked ones should be replaced.

When a filter's multiport is on but filtering does
not seem to happen, the spider gasket inside the multiport
may be damaged or worn and in need of replacement.

If the filter gauge shows high pressure but the filter does
not run, then it most likely needs a new gauge.

To find what causes a backwash line to have water coming
from it when the multiport is set to filter, check the
multiport gasket for wear or damage. The multiport
gasket, or the entire multiport, may have to be changed.
