OEM check valve used on the following Hayward cartridge and D.E. filters:
Check valves prevent the backflow of chemicals to pool equipment.
I broke the plastic retainer that holds the flow controller and check valve in place, EC 50, do you sell them?
How do I replace a ECX4077B1 Check Valve on a Hayward DE EC65 Filter?
how i can to install ecx4077b1 check valve?
The weight fell off my check valve will this cause a pressure problem? I have to keep bumping up the filter every few hours
Hi Chris, The weight falling off of the check valve will not create a pressure problem that will cause you to keep having to bump the filter. The flex tubes could be old nd need to be replaced or cleaned thoroughly.
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.
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.
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
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.
