We have a Hayward EC 45 filter with a damaged top. It is similar to a EC-10334P shown in your catalog (the one in the catalog is for a EC 40 filter). Does it fit an EC 45?

Kurt, Yes, this filter head (ecx10334p) fits both the EC40 and EC45 models.

Will the exc10334p fit our model EC-50 Series filter. I think this was purchased in the mid 1980s.

Hi Pete, Yes this would be the correct cover for your Hayward Perflex EC50 DE Filter.

Hi Bill, A crack lid would not allow DE powder to get back into the pool. There is probably a tear in one or a few of the Flex Tubes (ECX1032) which would need to be replaced.

I have a crack on my Hayward perflex filter head model EC-45. Is there a replacement filter head ?

Hi, Bill. This particular head is used with the EC40 which is the bolt-on style model. If you have the clamp style model you will need p/n ECX5000BP.

Hi, George. The replacement Head is a little less that half the amount of a complete EC40AC or the EC50AC units.

I need the male connecter for the Hayward EC-40 that connects the pump to the flexible pipe that goes to the pool? Seems to be 7/8 inch thread on one side and 1 1/4 " diam to connect to pipe.

I have the Hayward model EC45 and the filter head is leaking from the area where there is a gasket. Can I take this apart and replace the gasket or do I need to purchase the whole filter head unit?

Hi Terry, You can use the ECX1003 Diaphragm Gasket listed as key # 12B on the Hayward Perflex Parts Diagram
