How much pressure can this vessel handle? Could it be used to filter well water at 60psi?

Hi, Bob. This filter along with most swimming pool filters are only capable of handling a max working pressure of 50 psi.

I currently have a sand filter for inground 16x32 pool. If I were shopping for a cartridge filter, what size would I be looking for?

A     Answered on 6/27/2018 by InyoPools Product Specialist Hector F.

You would want to start by working with the gallons per minute rating that your current and filter can handle then locate the motor model, part or catalog number. With those two pieces of information just give us a call and we can try and recommend a cartridge filter that would suit your application.

Do you sell an item that is comparable to the Sher-120 Part #4666-122, 94223390 since that item is no longer available via your website

A     Answered on 6/28/2017 by InyoPools Product Specialist Patrick P.

Hi Pat, I would suggest the Hayward C12002 Star Clear Plus 120 Sq. Ft. Filter as a suitable replacement for the Jacuzzi Sherlock 120 Filter. The Hayward is not a drop-in replacement as the plumbing ports are not in the exact same spot, so you may have some slight re-plumbing.

do you have this system for sale. Sherlok 120 filter. If not does the Sherlok 160 enter change with this system . Will the 160 work for my pool. 20,000 gallons

A     Answered on 7/19/2016 by InyoPools Product Specialist Scott W.

If you're looking to buy the whole filter the part number is 4666-122, the cartridge is part number NFC1401. The 160 is part number 4666-123 and a larger filter is never the bad. It's better to oversize on the filter than undersize. Bigger filter will last longer and won't have to clean as often.
