Reverse osmosis water filter

I have a reverse osmosis water filter. The other day water production went from over a gallon of filtered water to 3/4 of a cup. We changed the filters thinking that may be the problem, but that did not solve anything. What else could be wrong with it?

Hi jennym123,

I'm Harvey the Master Plumber.

Your question is: You have a reverse osmosis water filter. The other day water production went from over a gallon of filtered water to 3/4 of a cup. You changed the filters thinking that may be the problem, but that did not solve anything. What else could be wrong with it?

This is a common problem. Can also be very frustrating. A small bit of debrie has been brought up by the flowing water and is stuck somewhere. As you can imagine this will restrict the flow. I would start with the on/off valve next to the cold water line first. Turn the water off first and take it apart checking for obstructions. Then work your way down checking the lines and any place you can. It's helpfull to have a bit of wire to probe with. If you turn it back on and the problem still persists then you missed it. Try again. Good luck.

Feel free contact me again!

Culligan reverse osmosis filter system has stopped providing water from the sink mounted faucet attached to the system.


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.

Always regenerates


I believe the ratio is 5-1, so when you use 1 cup it uses 5 cups to replace that cup. The reject water will slowly run down the drain, the extra four cups.

I have a 3 filter undersink system that says Reverse Osmosis on the tank. It is a 2 1/2 gal. tank and i get , maybe 2 qts out of it now. I have been replacing the filters as instructed.


The storage tank probably has low air pressure. On a 3 gallon RO tank empty the tank completely of water and adjust tank pressure to 7psi.

How do you know if you need to replace the RO membrane filter in the culligan good water machine


A TDS (total dissolved solids)meter is needed to test the Reverse Osmosis water and compare it to the feed water to determine how much TDS is being removed. Reverse osmosis membranes are designed to remove 80-95% of the TDS in your water supply.

For example: If your water has 500ppm of TDS the minimum TDS removal should be 400ppm leaving 100ppm. If the TDS from the Reverse Osmosis System drops to these levels it is time to change the Membrane.
Typically an RO system will consistently remove 90+% of TDS for many years. The normal lifespan for a membrane can be anywhere from 3-10 years. It all depends on the TDS of your water and your water usage. The higher the TDS the more frequently the membrane needs replacing. The other filters should be replaced every 6 months to keep the quality up and protect the membrane.
A TDS of 1000ppm compared to 100ppm is much more difficult remove to acceptable levels. I like to compare 1000TDS to taking muddy water, forcing it through a filter and getting drinking water. Where 100TDS may be more like a clear glass of water. Consequently a reverse osmosis system on high TDS will be less efficient, less gallons produced and filters will need to be changed more frequently to keep the quality and quantity up.

Culligan ac 30 reverse osmosis system - changed the filters, good flow for 3 days then began diminishing. Now nothing comes out of the faucet. Holding tank is empty.


I would pull out all the filters changed and check them. If a GAC filter is used as the post filter, before the RO tank, carbon fines can come out of the filter and can plug up the head on the RO system. Make sure the sediment pre-filter is not plugged and there is plenty of water supply. You may have lost pressure in the RO tank. A 3 gallon tank should have 7psi pressure when totally empty.

A drain tube in the water dispensing module constantly has some water flow. What is the purpose of this drain and how can I eliminate the water loss.


A reverse osmosis system drinking water system will waste a certain amount of water for every gallon it produces.
1. The higher the TDS (total dissolved solids) the higher the ratio of waste water to product water.
IE: An RO on TDS of 1000ppm may require 7 or more gallons of water to waste to 1 gallon of product water. TDS of 100ppm will have about 3 gallons of waste to each gallon produced.
2. It also depends on the Membrane capacity. Membranes for residential RO systems come sized from 7-75 gallons per day. If you are a heavy water user and have a low producing membrane the RO may not shut off until it gets to rest at night and fill the tank.
3. There can also be a problem with the automatic shutoff on the RO. When the tank fills up and the pressure equalizes across the system the ASO (which is just a simple diaphram system) shuts the water off to the system.
4. If there is not enough pressure in the RO tank the tank may fill up but there may not be enough back pressure to shut the ASO off. So the waste and product water go down the drain and it runs constantly.

Kenmore side by side dirty water


the problem might be linked ot your reverse osmosis system itself, something about filtering and storing previously filtered water, which if i remember correctly creates a "harmless" bio film the consistency of what appears to be brine shrimp sized particles floating in water. so i would remove the filter from the refig and flush out again.

Particles floating in whirlpool filtered water.


okay - we have had this same problem for around 6 weeks - We called a service repairman to come out and he said that these "floaties" are harmless bacteria. We should disconnect the filter and flush the system by using 1 gallon of water a day (wasting it) after the chlorine in the water is allowed to build up again then the "floaties"- bacteria- will go away---- gross :-( We will see if it works---
