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.

SOURCE: how to replace filter

Turn off the incoming water supply, turn off the valve on storage tank, open the RO faucet and let pressure off. Have a pan ready, remove the sediment pre-filter housing and post-carbon housing.
Use latex gloves when changing filters, add 1 tsp bleach to each housing and clean them thoroughly before installing filters. Make sure all bleach is rinsed out before installing filters. Turn the water back on to system, turn the tank back on and run 2 tanks of water out before using water again.

SOURCE: I have a Culligan AC

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

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.

Culligan AC-30 Tank not Filling and Recharge only produces minimal water.


You should change filters and membrane and then proceed. Replace both filters not one. You mat to buy new RO unit that you can find filters on line ie store (less than you are going to pay for Culligan) PROCEDURE FOR RECHARGING REVERSE OSMOSIS BLADDER TANK WITH AIR
When you turn on the faucet you notice low water pressure from the storage tank and only a quick burst of water come out of the system, and it dies down to trickles. Is the tank defective, i.e., bladder has hole and not functioning properly? Perhaps.

If you have the above problem and the tank is heavy (full), then try to relief the pressure from the air valve on the tank side. Is water coming out? If the answer is yes, then the bladder has hole and is defective, and tank replacement is due. If air comes out then it is possible that the air needs to be recharged.

Notes on bladder tank, please continue reading:

RO Tank useful life is 5-7 years. If the tank has been serving you for that long it is possible that the bladder had a hole and that tank replacement is due. If the tank is not that old, it is worth it to evaluate it for air pressure. In an empty tank, air pressure should be 7-10 psi. In a full/heavy tank, air pressure should be 30-40 psi. To be accurate, air pressure should be 2/3 of incoming water pressure. When the tank is full, and if feed water pressure to the RO system is 60 psi, then a full tank should have 40 psi. The RO tank has a bladder inside, and this bladder separates air from water. On the lower side of the tank is the air valve which is connected to the compressed air chamber. The top water inlet/outlet port (where the tank valve is mounted) is connected to the pure water chamber. So, when you turn on the faucet, the compressed air would squeeze or compress the bladder to force the water out of the tank.

You do not want to believe the tank is useless and want to do extra testing? If your answer is yes, please continue reading.

TOOLS NEEDED FOR TESTING:

1. An air compressor or air pump (like a bicycle tire air pump)

2. An air pressure gauge that is able to read less than 10 psi, and

3. Adjustable wrench.

STEPS:

1. Shut off the water supply to the RO system

2. Turn on the faucet to allow water to run until it stops.

3. Check to see if there is still water in the storage tank by lifting the tank. If the tank feels heavy, that means you need to recharge the tank and continue the following steps. If the tank feels light, that means you don't need to charge your storage tank at this moment.

4. Locate the air valve on the side of the tank. It looks like the air valve on tires.

5. Use air compressor or air pump to pump air into the tank. Keep the faucet on while pumping air, so that all water inside the tank can be purged out.

6. After all water has been drained from the tank, use an air pressure gauge to check the tank pressure.

7. The tank should have 7 psi of pressure when it's empty. Add or purge air if necessary.

8. Turn the feed water valve back on, and turn off the faucet to allow refilling of the tank.

9. finished.

What if the tank does not hold pressure and you see the same problem again? Bladder is out and you need to replace the tank.

Culligan water machine water is flowing very slowly


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.

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.

I am assuming based on your description that the system you have is a reverse osmosis system. If this is true, you most likely need to recharge the air pressure in your RO storage tank. I have included step-by-step instructions below. If you find that your tank is not holding air or the tank will not empty completely, the bladder inside the tank may be broken and the tank will need to be replaced. I have included a link to our selection of RO tanks as well. To recharge the tank you will need a bicycle tire pump and a tire gauge that will be capable of reading below 10 psi. If you don’t have one that reads in single psi increments, then a meter that starts at 5 psi will work.
http://www.freshwatersystems.com/c-32-reverse-osmosis-storage-tanks.aspx

1) Close the cold water feed valve (if you can’t locate this on your system, you may be able to turn off the cold water to your sink)
2) With the RO tank valve on, locate the valve stem on the bottom or side of the tank. (this will look like the air stem on a bicycle or car tire)
3) Remove the stem cap.
4) Drain all water out of tank through open RO faucet into sink. (Continue to leave the RO
faucet open throughout the entire procedure)
5) If the current tank pressure doesn’t empty the tank, apply tire pump to valve stem
and pump a few times. Flow will increase and then gradually decrease as
pressure equalizes. Do not overcharge the bladder during this procedure.
6) Repeat step #4 and #5 until tank is completely empty. (Tank is empty when additional
pumping produces no more water)
7) At this point, adjust EMPTY tank to exactly 7psi. (Gauge reading midway between 5
& 10psi is sufficient)
8) Turn off RO faucet.
9) Replace cap on valve stem
10) Open cold water feed valve.
11) The water is useable immediately; however, tank will take a few hours to completely fill.

Air tank (underneath house) does not push water out of spigot in sinke or refridgerator.


You need to test the air pressure with the tank totally empty, remove the tube that is going into the tank and open the tank valve to release all water, if water is in tank and does not come out your bladder is finished and you will need a new tank, if you are able to get all the water out then you need to test PSI again and it needs to be between 7-10 psi, this way when the bladder fills up again with water that pressure will be the ideal 40-50 psi.

Culligan RO sstem has recently stopped producing more that 6 oz


This might be a possible tank pressure issue. This could also be a clogged filter. I would first check the tank pressure by using the following steps

Necessary Supplies:
1) Tire Gauge marked in 5psi increments (ie 5, 10, 15, 20psi, etc.)
2) Bicycle tire pump for standard type bike tire valve

To recharge RO System Tank:

1) Close cold water feed valve (valve located at some point along the cold water line from street plumbing).*
2) Leaving RO tank valve on, turn tank on side & locate valve stem on bottom side.
3) Remove stem cap.
4) Drain all water out of tank through open RO faucet into sink. (Continue to leave RO faucet open throughout procedure)
5) If current tank pressure is insufficient to empty tank, apply tire pump to valve stem and pump 10 – 15 times. Exit flow will increase and then gradually decrease as pressure equalizes. Do not overcharge internal bladder of tank during this procedure.
6) Repeat step #4 until tank is completely empty. (Tank is empty when additional pumping produces no more water)
7) At this point, adjust EMPTY tank to exactly 7psi. (Gauge reading midway between 5 & 10psi is sufficient)
8) Turn off RO faucet.
9) Replace cap on valve stem and reposition tank in upright position.
10) Open cold water feed valve.*
11) System water is useable immediately, however, tank will take 3-4 hrs to completely refill.
