Have a SY 2650 under sink filter system that whistles

I think this will fit. $30 but now that you know its compatible you may find it cheaper.

Run the tank empty of water at least 2x. This should take care of problem. You really should dump 2 tanks of water each time because carbon fines can get in the tank when changing new filters.

This system should be under warranty still. If it is running to drain constantly bypass the system and call Culligan for service. Unplug it for 2 minutes and it may reset.

I suggest installing an in-line check valve on the feed line to the Culligan filter and resetting the meter on the filter system. You may be getting water water feeding back out of the filter system when other faucets are run causing the meter alarm.

This is under warranty still call Culligan for service. Is it flashing an error code? In the meanwhile unplug the system for two minutes and plug back in, this may reset the controls.

The pressure on an EMPTY tank should be 8-10 psi. Be sure the tank is empty before checking the pressure. A good way to empty the tank is to connect a small air compressor to the air valve on the tank, open the systems faucet, and turn on the compressor. A bicycle pump works too....Just more of a workout:)

I have used numerous sets of Culligan filters and membranes from this on-line supplier and had very good success with them. No issues as with other knock off filters. No I do not work for them.

Hello,

They could be loose, try to tighten them a little bit :)

You can find info on www.salvajor.com under the tech info tab. You'll also need to know which control you're using. You also need to know if the disposer is one or three phase. These machines are designed to be run by salvajor controllers and not just normal switches.
