SOUNDS LIKE A CRACKED SUCTION STUB OR LOOSE THREADED FITTING SUCKING IN AIR.

OR THE CHECK VALVE IS FAILING AND ALLOWING THE WATER TO LEAK BACK SLIGHTLY OR ALL THE WAY BACK. YOU CAN ALSO ADD A FOOT VALVE AT THE END OF THE PIPE.

LONG SHOT, BUT THE BLADDER TANK IS CHARGED WITH AIR AND MAY HAVE A HOLE IN THE BLADDER CAUSING THE TANK AIR TO ENTER THE SYSTEM. SHOULD RUN OUT QUICKLY THOUGH. HOPE THIS HELPS, JODY

Is a 30-gallon bladder diaphragm holding tank best for me?


Yes, a bladder type tank is a lot more dependable. You can install a diaphragm into your bladderless tank but it will still need to be charged with air periodically.

Why does my submersable well pump run constantley?


Hi Ben..
Be sure you have an air cushion inside of your tank, or otherwise it will turn on and off too fast. Normally you fill/set the air first.... but it can be done either way, just be sure that you have about 1/4 of your tank an air cushion, this stops the pump from cycling on and off to fast

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.

Ao smith 1 horse house water pump. water pump only fills tank half way to 3 /4 . pump does not stop running.. water pump leaking a little water out of water valve spiot


Hi, W/D here.
The tank has to have an air cushion in it for the water to be delivered as water is not compressible. Ideally, the water is expelled from the tank without air leaving the tank, and then the pump starting to refill the tank. The air in the tank is supplied either by an air bladder installed in the tank, or by an air injection system where a little air is injected into the tank every time the pump runs and shuts off.
A little leak at the pump is not a big deal, but should be capped off or the faucet repaired/replaced at your earliest convenience. Ideally, the water level in the tank should be closer to 80%; so if you have an air injection system, you might let a little air out of the tank (if you have a top valve), and this might cure your cycling problem. With the tank level as is, you are probably getting some air in your lines into the house. If you have an air bladder in the tank, the required pressure of the bladder, with no water in the tank should be on a sticker located at the schrader valve on the top of the tank (A schrader valve is similar to the air inlet valve on a bicycle tire). The ones I am familiar with are set around 28-29 psi. If you have an air injection system, it may need to be replaced. If the costs are close, I would elect to go with a bladder tank, as I've found that they eliminate many of the problems associated with the air injection type.
Fix or cap the faucet so you have no leaks showing at the pump or tank. Catch the pump running, and wait for it to shut off. When it does, close the discharge valve to the house and wait. You may need to trip the breaker for the pump. Watch the pressure gauge. If the pressure falls, the problem is with the well, and you may need to pull the inside well supply line from the casing and make repairs at the foot. My experience has been that it is better to replace the leathers, jet valve and foot valve all at once than to hope they hold if I repaired only one part.
If the gauge holds after 10 minutes, open the valve. If the pressure falls, the problem is on the house side of the valve.
Resolve any issues on the well before checking further, as that's where most well problems originate.
Adjust your tank level and pressure. If the pump continues to cycle, you may need to replace your pressure switch.
Best regards, --W/D--

My current water tank was installed 12 years ago With Bladder. 1 hp motor. 80 gals. Water Pressure is consistantly low. When reset to 40-50 lbs, it drops shortly after back to thirty lbs in the house....


If I understand you, this is a water well. For pressure to drop, water must be going somewhere. If you see no leak in the tank, that is not the problem.
Check all outlets, faucets, toilets, showers, outside faucets, etc. If you see no leaks and the pressure is still dropping, there is a check valve either before the pump or in the well and this could be leaking back. Either way, the pressure should drop to zero unless the pump comes back on.

When adding air to a pressure water pump ,i


Sounds like the bladder is gone or inproper air pressure in water storage tank.

Bladder goes bad check it out with step 1
1-
One way to check for sure with everything hooked up. The air valve on top of the tank if pressed you will get water out of the valve which should be only air. This will let you know it should replaced.

If Tank bladder is low in air and not water coming out.

2-If it checks ok put an air gauge to tank to check the air pressure, with a standard 40 gal tank you will have 28 psi of air in tank for it to function properly.

Lots of water on basement floor at pressure tank.


sounds like the bladder tank at the well is ruptured this will cause pressure surge, and pump short cycling, and needs to be replaced asap.

Why is the pump cutting in so much


Check your water pressure tank air pressure, turn off pump, drain off all water pressure and using a air pressure gauge check pressure at the schrader valve on the water pressure tank. It should be 2 lbs below pump cut-in pressure, they come factory charged at 30 PSI...works for most residential systems. Most likely you have a bad bladder in pressure tank.

Other possibles are a broken line between pump and pressure switch/pressure tank or bad pressure switch.If you have a pressure gauge on the water system(should have one near pressure switch) see if it is cycling at the right points if it is the switch is good. If pressure is dropping with NO water uasge in house you have a leak.

Most likely a bad pressure tank bladder is the problem.

I have a model C48A93A06 1/2 horse power pump motor and it pumps water fine,but, it will get within 2lbs of the cut off pressure and just sit there and run and will not cut off unless I bump the pressure...


I would check the holding tank pressure, if you have one with a bladder. Turn electric off to the pump, and drain all water from the tank. Take a tire pressure gauge and check the tank pressure at the air valve on top of the tank. That pressure should be two lbs less than your cut-on pressure. If the cut-on pressure is 20 lbs, then the tank pressure should be at 18 lbs. If there's too much pressure in the tank, it wont let the pressure switch work correctly. If you get water from that air valve, then the bladder is ruptured, and a new tank is needed.
I hope this works for you!

Flotec 42 gallon water tank - short cycling and changing water stream...do I need a new tank or could it be another problem?


These holding tanks are pre charged with air which in turn pressurizes the water. The tank has a bladder and an air valve on top. The pre charge ,over time, loses pressure, and the tank has to be pressurized again.
  • The well pump needs to be turned off.
  • The water has to be drained from the tank
  • Air is put into the tank from the air valve on top of the tank, and is measured with a tire air gauge.
  • The pre charge pressure is set to two psi below the pump cut in pressure.
  • In other words if your pump kicks on at 30 psi, the pre charge pressure is set at 28 psi. If the pump kicks in at 20 psi, the pre charge is set at 18psi, etc.
  • After you pressurize the tank, turn water back on.
  • If water comes out of air valve on top of tank, then the bladder is ruptured and you need a new tank.
  • Hope this helps!
