Charles, This check valve just slides into the outlet port of the filter from the inside.

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 ?
 Reply

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?
 Reply

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.

Hi Doug, To remove this check you will have to pull it out of the inlet port depending on the model of the filter you have.

The Earth was coming out of return - check valve fell apart

Written on 8/17/2022 by Guest

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!!
