OEM check valve used on the following Hayward cartridge and D.E. filters:
Check valves prevent the backflow of chemicals to pool equipment.
My Hayward 50 filter just does not filter the water and the powder seems to shoot through its only two years old and my pool is 15k gallons above ground
I did the following
1. Back flushed it
2. Replaced the check valve
3. Pressure is about 7lbs steady
4. Flow is good
5. Put 5lb of powder
Any recommendations

Hi Charles, I am assuming you have the Perflex EC50 DE Filter, if so then I would check the condition of your Perflex DE Fingers and replace any that are torn or damaged. Damaged DE fingers are typically the culprit when getting DE powder back in your pool.

Could a bad check valve cause earth to return to pool ?

Not typically. The most common cause of DE coming back into the pool is a broken ar ripped grid. The manifold could also be compromised, but that is less likely.

If my check valve is bad will that cause my filter pressure to run high?

Hi Joe, A bad Star-Clear Check Valve (ECX4077B1) will not cause the filter pressure to run high. You probably need to have the filter thoroughly cleaned out or replaced.

Saw earth coming out of return and filter not working properly. Took tank apart and saw it needed to be changed. Check valve is at the mouth of the filter. Replaced and working great!!

This item was an oem part. It was fairly priced, and its worth replacing every so often. It takes a lot of abuse with all the chemicals and water pressure passing thru.

I RETURNED IT FOR THE FULL PRODUCT INSTEAD OF JUST THIS SECTION. BETTER TO REPLACE "ELBOW WITH CHECK VALVE" INSTEAD OF JUST THE CHECK VALVE. EASIER REPLACEMENT WITH TOTAL UNIT.
