We Are Getting Chunks Of DE In Filter Basket...

We have a 10,000 gallon heated indoor pool and have new DE filters in place. Each day we are having to backwash and replace DE. When we backwash we are getting chunks of what we thing are hardened DE but are not sure.

Additionally our heater and circulation pump are shutting off because of high pressure readings in the filter.

Could this be caused by clogs?

Thank you in advance for your assistance.

Thanks for your question Tom

DE swimming pool filters are the very best at filtering your pool water...but they are the most time consuming. When they're backwashed, you never can know how much DE is actually being backwashed out, and therefore, you really can't be sure if you're putting in the correct amount of DE.

I would advise you to clean the grids from top to bottom. Inspect the DE grids for rips or tears. If they're more than 20% worn, ripped, or torn, they'll need to be replaced.

Also, check the pool pump, basket, and impeller to be sure that there are no chunks of DE in the system that can clog up the pump motor.

Be sure the pump motor is off and the breaker switch to the motor before doing anything.

Your high pressure issue might be related to lack of flow through the DE filter. If the filter is too clogged with DE, then that would restrict the water flow and cause the pressure to rise.

Be sure you're using a DE scoop, not a coffee can or something similar. You want to get as close as possible to the right amount of DE.

Hope this helps and have a great Summer
