I put in a swimming pool sand filter cleaner/degreaser and left it overnight as instructed. I have gone out to backwash and rinse but nothing is happening. The pump noise is on but no pressure. When turned to backwash the pump noise remains but no pressure and no water coming out.
The same with the rinse and waste cycle. No pressure either when turned on to filter but the usual pump noise. All was o.k. before.
I am wondering if I put the cleaner in the correct place.!!!
Hope you can help.
Thanks for your question Margaret
I just recently de-greased both YMCA pool filters, and here's what I do.
First you need to be sure the pump motor is off. If you can you'll want to close the skimmer and bottom drain valve to have a filter tank full of water.
Open the lid to the pool sand filter, shake the bottle of de-greaser and pour it in the filter.
Open the skimmer and bottom drain valve to allow the de-greaser to soak into the sand filter media and let it sit overnight.
In the morning fill up the filter with water, prime the pump motor, and open the skimmer and bottom drain valve. This is to ensure there's enough water in the system.
You want to start in backwash mode because if you start in filter mode all the de-greaser will end up in the pool and you'll have a big mess on your hands.
