    Is My pressure to high?

    I have a Hayward S180t sand filter and I just replaced my faulty pressure gauge yesterday. The pressure is now at 20, but the manual says bar is 3.45. I backwashed the filter for about 10 minutes, but pressure remained the same. Am I ok, or is there something else I need to do?

    Thanks!

    20 PSIG could be prefectly normal for your system. What size eyeball do you have? I have a 1" eyeball and my pressure runs 11 PSIG clean my Sis has a ½" eyeball and hers runs 18 PSIG clean. It all depends on the makeup of the system.

    Don't know if it helps, but 3.45 bar is approximately 50 psi.

    maybe 3.5 bar is the max pressure for which the filter is rated?

    The eyball is the last little adjustable part on your return jet inside the pool that allows you to direct the water flow. They are referring to the hole size in the "eyeball".

    Not stupid. It's the part in the pool on the return that the water comes through. Most of them you can swivel around, like an eyeball, hense the name!
