when i fired up my pool this year I had a horribile vibration sound coming from the heater. At first I thought it was the heater however I noticed the water in pipe is shaking pretty bad that comes out of the jacuzzi filter and feeds the heater.... still thought it might be the heater "perhaps a valve blocking water flow" however when I grabbed the lever on top of the sand filter and applied a little pressure down the noise totally stopped. Wondering if anybody has any experience with that.... Do I have a faulty sand filter or is it the heater...

You probably need to disassemble, clean and lubricate the multiport.

thanks for the quick responses from both of you.. really apprieciate it
are you referring to the valve on top of the filter?

I was thinking about ordering a new valve and getting some new sand.. the sand hasnt been changed in a while....
the only thing that has me concerned is finding the right parts for this filter..
everything I see online is made by calvin... my filter and valve was made by cantar
also having a hard time finding replacement parts for the inside if needed..

My wife is telling me to just buy a new one... However really dont want to spend the money unless I have to
Are Calvin and Cantar parts interchangable

it is the correct model number just a different manufacturer

truly apprieciate the help..

James can help on the valve.

The sand should not need replacing unless you have been using Floc and Clarifier and circulating it through the filter. Sand is a million years old all ready. The short time it has been in your filter is insignificant.

It may need a deep cleaning if that has never been done. See Deep Cleaning a Sand Filter

I think that it's a Jacuzzi filter. Inyo pools should be able to help you with any parts that you need.

Mostly, you just need to clean and lubricate the stem O-ring where the diverter stem goes through the multiport lid.
