I have a C9002SEP. Can I use a filter cartridge in it instead of DE Bag Assembly?

Mark,I recommend staying within the bounds of what the manufacturer suggests per their manual. So I would stick with using the DE Bag assembly.

Hi Essam, This will be the correct bag assembly for the C-LE-42114 unit.

Similar to others: serial # 21121504005077015. Is this the correct bag?

A  Answered on 9/18/2019 by Industry Professional

This separation tank bag works with the Hayward Star-Clear Plus Separation Tanks made in and prior to May 2004. From your serial # it would appear this is correct. This is used in Hayward Star-Clear Plus Hayward C9002SEP DE Separation Tank (Star-Clear Plus)

The old bag has rotted and was torn, allowing DE to bypass the collection.

The big issue was to determine if this was the correct bag for my unit since my DE collection unit does not have a date, only a serial number. One other vendor just told me that they didn't know if this bag would fit or not; the team at Inyo went above and beyond and found out for me. I ordered from Inyo even though another vendor was $5 less.

I compared the dimensions with the old bag assembly when the new unit arrived; perfect match. I lubed the O ring and installed the new bag in the housing. I was waiting to backwash my pool filter so I would not discharge DE into my yard (grandkids play out there). The collector bag from Inyo worked great! I installed the DE collection unit to stop discharges of DE into the yard, the water is so clean that I can backwash into the pool to save water if I want to.

Were these instructions helpful?
