i have a model hayward model ec50c93s de pool filter. my question to you is the filter did not come equipped with a back flushing valve, i do not believe the bump handle adequately removes old DE and particular matter form the filtering fingers (thereby not adequately cleaning the fingers - causing inadequate run times before filter developes high pressure),when i install this new part can i install a back wash valve to reverse the flow of water to better clean the fingers ?

Hi, John. Unfortunately, the EC Series filter is not compatible with a backwash valve. You will have to replace the entire filter with a DE Filter that is.

Is the Elbow Assembly with Check Valve included with the filter body or does that need to be purchased separately?

A  Answered on 11/14/2016 by InyoPools Product Specialist Scott W.

The filter comes with the check valve already installed.

What else is included with the tank? Guage? any internal parts?

A  Answered on 7/11/2016 by InyoPools Product Specialist Lennox H.

Hi Bob, Only the pressure gauge, adapter, and the adapter o-ring are included with the Tank Body. No internal parts are included.

How do I know that this is the same tank I need - I have seen various flow rates for these filters but I think that is determined more by the filter tubes etc. If I have an EC-65 this is what I need. Also - I want to know shipping options - including Saturday delivery so I can install it this week end. Is that possible?

A  Answered on 6/11/2016 by InyoPools Product Specialist Lennox H.

Hi Jessie, This is the correct replacement for the Perflex EC-65/EC-75 filter. It would not hurt to get the Hayward EC65/EC75 O-ring Kit - APCK1150 You can use the shipping calculator feature on the website to calculate expedited shipping. We do not offer Saturday delivery.

Are the EC-65 and EC-75 the same size? I need to replace the EC-75 tank for my filter

A  Answered on 4/2/2016 by InyoPools Product Specialist Lennox H.

Hi Charlie, The EC-65 and EC-75 are the same size as far as the canister but the Flex Tubes are different sizes. So this Body can be used for both the EC-65 and EC-75.

Was seeing leakage at top of Hayward filter

Written on 10/13/2017 by Guest

First noticed leakage at the top of my filter and thought the gasket needed replaced. Ordered and installed new gasket but in doing so saw that there was a hairline crack or two near the top of the filter body. So to "save" $ I coated the cracks with marine epoxy. Positioned new gasket, tightened down top of filter that holds the diatomaceous earth fingers and turned on the pump. Great. Next day the pool was down a foot of water as the epoxy patch job did not hold and water was spewing out the cracks under pressure. Thank goodness the pump cycle had been short.. Ordered a new body and when it promptly arrived I did the simple switch out and all is as it should be except my water bill is higher this month.

Were these instructions helpful?
