Where does check valve ECX4077B1 go?
 Reply

A  Answered on 10/21/2020 by InyoPools Product Specialist Hector F.

Hi Pete, most often these check valves go in the return line at the filter however it will depend on the specific model filter to confirm its exact location as this valve is inside of multiple filter models.

Hi, John. In order to assist you, we will need to know what type of union you're using.

how i can to install ecx4077b1 check valve?
 Reply

A  Answered on 10/12/2016 by InyoPools Product Specialist Stacey M.

Hello Vladimir, if you look at the parts list located on this manual, your check valve should be installed before 1 1/2" male union.  There are no installation videos of this that I have found.

The weight fell off my check valve will this cause a pressure problem? I have to keep bumping up the filter every few hours
 Reply

A  Answered on 6/18/2016 by InyoPools Product Specialist Lennox H.

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?
 Reply

A  Answered on 7/14/2015 by InyoPools Product Specialist Lennox H.

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 ?
 Reply

A  Answered on 6/17/2015 by InyoPools Product Specialist Brian M.

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 Any recommendations
 Reply

A  Answered on 5/26/2015 by InyoPools Product Specialist Patrick P.

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.
