When checking the pressure of the storage tank dirty black water comes out

The bladder is ruptured in the tank. The tank needs to be replaced.
Anytime the air valve on a water storage tank IE: Well tank or Reverse Osmosis tank has water coming out when you depress the vale the tank needs to be replaced.

1998 lincoln mark viii all air flow diverts to defrost vent when a/c on and you accelerate...goes back to correct vent when let off gas

Usually a sign of a vac leak or a faulty vac storage tank. The storage tank holds engine vac to prevent your issue. Engine vac drops to zero when you are accelerating.

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.


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.


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.

The compressor air supply line from comp. to storage tank has a tee at the tank with a brass pluss in it with a tiny pin hole and that is allow air to be expelled. Is this a safety plug or can it be...

no, do not block with a solid plug. This allows air to bleed off the compressor so it will restart when pressure switch makes. If air continually bleeds out of this hole i would check the tank check valve . It is bad or has trash or something keeping it from closing. If check valve is bad it will allow air from the tank to bleed down until compressor starts or no air left in tank if shut down

I have to hold the gas pump to put gas in my car. Is there air in the tank?

You have an EVAP System Malfunction that will
not allow you to fill the gas tank

There are several electrical solenoid type
valves in the system,one has failed

When you fill your tank all air is recovered by
the hose your using to fill it & put back in the
ground storage tank,not into the air

The failed vent valve in the EVAP System prevent
air out

I changed the filters, put each in properly, turned the water on and I have water in the tank but no water coming out of the spout. What should I do?

There is no air pressure in storage tank. Take the supply line off the tank, pump air into the tank until all the water is out. Then let out enough air until there is 7lbs of air left. This is bladder tank and they loose air pressure after a while. Hook it back up to RO and you are good to go.

I want to add an extra tank to my existing vertical compressor how do i plumb it in there is a round cylinder on top of tank that my gage is mounted in is that a regulator.

If you would like to have regulated air pressure in your extra tank then just remove one of the quick connects and install a t-fitting. On one port reinstall the quick connect; on second port install jumper hose to second tank. If you would like to store full tank pressure in the extra storage tank, remove the safety pop valve and install a t-fitting. Reinstall safety valve on one port and run jumper hose to tank. If there is a more convenient direct access to the tank then use it instead (do not use drain valve port). Also use caution on selection of extra storage tank. Some shop compressors (two stage) are set above 160psi. Make sure your extra tank and jumper hose can handle the pressure. Good luck

I would suspect a water circulation problem, most likely air in the system, if the water can't flow it will overheat.

If the problem persists after bleeding check to make sure the pump is running

Jenn Air Ice Maker Ejector Fingers Freeze Up

Hello, Yes you may be on the right track. Some manufactures like Jenn-Air, Viking, Sub-Zero, etc. require a higher inlet water pressure across the inlet solenoid valve to close the diaphragm after the ice machine stops calling for water. There are multiple solutions. But first, check the water pressure to your home to make sure you have 65-70 psi of pressure entering the home. Here is a link to our web site for a reasonably priced solution to increase the discharge working pressure from your RO System storage tank to the Jenn Air: This is a modification that can be done to your system. It is a Patented Piston Actuated Permeate Pump that relieves the Permeate or Pure Water "BACK"-Pressure when the pure water enters the storage tank so the tank can store more water and build more working pressure. You could also increase the size of the storage tank, increase the size and daily production of the Membrane Filter to recover the tank water quicker, or add additional storage tanks for more volume of storage. Another method would be to use an "Atmospheric Storage Tank" with the RO System, and a Pressure Delivery Booster Pump to **** the water out of the storage tank and Pump it to the required location under higher pressure and flow when compared to the Conventional Pressurized Bladder Tank that you own now. The drill down path to our site for this information would be:, Purification, Reverse Osmosis, Residential, Pump Assisted Reverse Osmosis, EPS-3TPP, or other systems on that page. Hope this helped.
