The best way to determine this is to backwash the filter and see what the pressure is at that time. Then go 7-10 PSI above that and this will be your pressure to watch to tell you when to clean your filter.

No absolutely not unless you want to waste a lot of water you backwash a pool when the pressure in front of the filter becomes too high or goes into the red.

Where and how do you apply the DE to the pool filter?

After the filter has been backwashed, the filter valve is switched back to filter and the DE is added to the skimmer. The amount of DE to use should be shown on the filter and depends on the size of the filter area. The DE should first be mixed in a bucket with water then poured into the skimmer with the filter running.

What causes pressure with a pool pump to drop?

A clogged filter? The pressure AT THE GAUGE will drop after the pool is backwashed and also during vacumning. As the filter becomes clogged the pressure AT THE GAUGE will increase. The opposite effect occurs at the inlet eyeball.

Your D.E. filter should have a pressure gauge on it. When the pressure reaches about 20 psi this is an indication your water flow is slowing down due to trapped debris in your D.E so a backwash is necesssary to flush it out.

What is a DE swimming pool filter?

Simply put, Diatomaceous Earth (DE) are the bones of tiny little animals that lived millions and millions of years ago, diatoms. This DE is used to coat the "grids" inside the DE filter which captures and filters particles as small as 5 microns. When the filter pressure rises, the swimming pool DE filter is backwashed in the same manner as a sand filter. A slurry of DE is put into the skimmer to "recharge" or "re-coat" the grids of these swimming pool DE filters. This type of filter is effective and efficient but a little more expensive to maintain. Some call it the "water polisher" of pool filters.

Why does my pool filter blow dirt into the pool?

I assume you have a sand filter if so you most likely have broken laterals in your filter. A lateral should allow water through but not sand. if you have a DE filter and you are getting what appears like sand in the pool, you have one or more of the filter grids that have holes and the DE is passing through the filter grids back to the pool.
