Filter makes horrible noise then quiets

[Elliottjc314]

For the last 2 weeks or so, our pool filter makes a horrible screeching, vibration sound when the pump first starts. The noise lasts 5 minutes or less then all sounds return to normal. The sound and vibration does not seem to be coming from the pump or motor .
The cartridge filter cylinder is where the vibration is felt and where the noise seems to be coming from. Any ideas on what could be causing the problem. Water level is fine, filter baskets are clean. Where else should we be looking?

We thought so too, however we have opened the valve at the top of the filter housing to release any air....... and water comes out. I'll have to get the filter details tomorrow in the daylight. Thank you for your thoughts.

Sometimes the single cartridge filters have a gap at the top or the bottom and water slips past and makes the sound.

You might be able to wrap some tape around the center insert to create a tighter fit.

NOISY POOL FILTER

I replaced my Jandy Pro DE Fan filter with a simple lightweight Hayward Swim Clear Model C150S about 18 months back. Has worked flawlessly and far easier to clean. It is a paper cartridge that I replaced about 5 months ago. However, it started making a loud high pitched sound like a router or...

The filter is Sta-Rite PXC75.
When the pump turned on today the noise lasted less than one minute. Then mellows out to normal sounding equipment.

Probably a loose fit between the cartridge and the top or bottom insert.
