Top 20 Culligan Under Sink Water Filter Questions & Answers

plastic line and fitting are a snap in item push the line in and at the same time press in the ring at the end of the fitting that releases the clamping action of the line make sure that the water is turned off and the pressure in the line is released

Well the simplest answer is the gasket isn't seated properly. The standard approach is to remove the cartridge, check for any foreign material (dirt, sand, grit, etc.), rinse with clean water if necessary and reassemble. Sometimes these cartridge units can be fiddly to get the seals to 'seat' properly so once you're sure that the parts are together nicely then you can use a bit of pressure to tighten them up. They usually need to be fairly tight.

Since unfiltered water went through it for a couple days, I would guess you have mineral build up. If this is the case, be careful about trying to use it. There are certain products you can buy to unclog the pipes. Most will have you pour them down through the pipes connected to the polishing filter. If you can take the pipes apart, I suggest going pipe by pipe to see where the build up is. Elisa Jed ' http://www.watertectucson.com

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.

If it has only been one year, check the warranty. Who said that it needed to be replaced? Oftentimes, a repairman can adjust the pressure to increase the outflow without needing to replace the whole unit. Elisa Jed ' http://www.multicrafthome.com

The rubber washers tend to perish after a while and with the water off the rubber has most likely dried out. You need to pull the tap apart and change the rubber washers to put things right. It's not a hard job to do yourself but there are 4 standard sizes of tap-spanner; one of them is probably right! Give the whole assembly a rinse with water from a jug you set aside before shutting off the main water out the front of the house. <ahem> That's right, before you dismantle the tap make sure you shut off the water supply to the house!If you're still not sure, call your local handyman to do the job. He can probably do it on a shorter time frame and just as well as a plumber.

Contact Whirlpool directly. Filters may be faulty however it is likely an installation problem. They may be able to walk you through the installation process to check everything is done right. If you're lucky and they decide the filters are faulty, you may get a new pair free!

Depending on which type of plastic you have, it should say on it somewhere and it should look like a triangle and it will tell u pvc or nilon or abc. Then go get that type of glue and seal it with the correct glue. You could also use a food grade silicone, but remember to rough it up with some sand paper.

You can get replacement cartridges for all the H series through AC series RO systems on line from several suppliers. I use them and they work just fine.RJH2O

That's the drain for the reverse osmosis system. It should be tied into a waste line under the sink.RJH2O

check the micro setting of the cartridge and if it is ceramic or not. If ceramic and it is dirty and slimy then all you need is the back of a knife and scrape it back until the ceramic is clean. If it is carbon it may be blocked and will need replacing with a new one.

Green is the color it should be when producing GOOD (low TDS) water. A constant Red light indicates the TDS is high (relative to what the normal TDS rejection is on your water supply) and the membrane needs to be replaced. Frequently the TDS light will be RED when initially drawing water at the RO faucet because of a spike of TDS coming through membrane from static water in line.
I suggest taking a sample of pretreated water and RO water to a dealer for a TDS test to see if the Membrane needs replacing.

If by "Holding Tank" you are referring to the bladder tank for your RO, then you need to turn the water off to the RO system, drain the RO tank of any water, check the pressure with a tire gauge at the air valve (just like there is on a car tire). A 3 gallon tank should have about 7psi of air.RJ

When you put air in the tank did you make sure all the water was out of tank? In a three gallon tank there should be 7 lbs of air, 10 gallon 10 lbs of air.
There can be many reasons for no water in tank.
1. Bad bladder in holding tank. No back pressure on membrane (all water going to drain)
2. Faulty membrane (all the water going to drain)
3. Bad capillary tube (all the water going to drain)
4. Plugged check valve at top of membrane (no water)
5. Faulty water feed valve (piercing valve)
6. Fines from post carbon filter have plugged up the manifold (head) of RO unit.
7. Bad valve on RO tank
8. Plugged drain line

Here is a manual for a Culligan H-30. Basically the same unit. The diagram shows how to replace o-rings.http://www.freshwatersystems.com/support/H-30.pdfRJ

The storage tank is probably bad. Shut all the water off to the RO, drain all the water from the RO tank, check the air pressure with a low pressure tire gauge. PSI should be 7psi with a 3 gallon tank. 12psi with a 10 gallon tank.Add air to tank with a bicycle pump.RJ

If the RO is not shutting off and there is no water from tank there are several things to check.1. The product water tank is probably low on air. The tank may be full but no water will come out. Put enough air in tank to force out all the water then reset air pre-charge to 7psi for 3 gallon tank.2. The capillary tube / check valve of RO system is bad. This puts back pressure on membrane to help create water. 3. The Automatic shutoff is not working, causing the unit to run constantly.I would have to know what model RO it is to narrow down the problem further.Depending on the Membrane production 10, 25 gpd, etc. and the TDS of water it may take 24 hrs to fill the tank.RJ

If the "black hose" is about 1/2" in diameter it attaches to the drain elbow on the left side of the valve. Use a hose clamp, cut some of the drain line back (about 2") slide it back on the drain elbow and clamp it on the elbow.If the black hose is 3/8" it attaches to the fitting on the salt tank, which attaches to the float.If it broke because it is brittle I would go to any water treatment dealer and get a new piece of "brine line" to replace it.RJ
