When we use our sink faucet there is a loud noise coming from our culligan water appliance. Is this a bad connection or maybe the filter has to be changed? The problem has been happening for about 10 weeks

This happens when the cold water is run. As cold water is drawn water is being pulled from the inlet of the RO system. This will cause a whine or squeal from the RO. Install an in-line check valve on the feed line to the RO system. This should alleviate the problem.

Low pressure


Depending on your faucet, I bet the problem is some debris that came loose and is blocking the flow at the valve that the faucet handle turns. 5 minute fix.

Turn off the water supply under the sink
Get a Phillips screwdriver and a flathead one
Get a pair of expanding pliers

Usually, the faucet handle comes off straight up when you remove the Phillips screw on top. If you cant see a screw, it may be hidden by a cosmetic cap (this is what the flathead is used for-to pop the cover off)

When you remove the handle, there will be a section that needs to be removed using the pliers turning counter clockwise. Once that comes up, the valve should lift straight out.

I bet you will se a debris obstruction there....easy fix to clean it.

Reassemble in reverse.

I hope this works.

Our Culligan water system under sink keeps backing up when we use it to get water - we only have this problem when we turn on the Culligan tap to get glass of water.


If you have an air gap faucet and the water is coming out there. The drain, for the RO, is plugged up or the drain line is pinched.

You are getting water feeding back to the kitchen faucet from the filter system. A check valve needs to be installed on the line feeding the drinking water system to prevent this. Excess pressure may also be causing these problems. An in-line flow restrictor may alleviate the dripping.

A replaced the Culligan 250A filters and now everytime you turn on the water from any faucet in the house you here 2 beeps.


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.

My culligan water filter makes a gurgle sound


The reverse osmosis faucet you have incorporates an AIR GAP to prevent cross contamination to the RO system. The waste water first goes up the to RO faucet AIR GAP and then goes to drain. The "gurgling noise" is the waste water going to drain. Some of these are much noisier than others.

Hose connection


The feed water goes in the bottom and the product water comes out the top to faucet.

The battery is either dead, the TDS meter is bad or there is a bad connection at faucet.
Replace the battery to see and run water for several minutes to see if light works.

My Culligan RO faucet has an ''air gap'' leak. How do I clear the clogged debris causing the water to constantly run? Culligan told me that the Faucet/Air gap is clogged. Need to dislodge the debris.


Normally when it leaks out the weep hole the drain line is plugged under the sink....turn off the ro to where it's not making water, disconnect the drain hose and flush it out....make sure the adapter that's connected to the drain pipe is still lined up with the hole if it was moved the water can't get to the drain.
