Hot water boiler pipes are banging


First step is to bleed all air from the system. Add more manual vents and have at least one automatic air vent if necessary to properly bleed. An air filled compression tank without a bladder makes it difficult to control air in the system; system pressure is difficult to control. An air tank without bladder is more common in older systems. Replacing an air compression tank with a pre-charged bladder tank can be a great benefit in maintaining system pressure. If a bladder tank is already in place it may have a leak after many years of use. If the problem persists, then check the bladder to see if it has a leak. This may not be easily done during system operation and requires removal. Tanks come in various sizes; get a larger rather than smaller tank. A great help in the long run and will pay for itself in service calls quickly.

Pump starts and stops when using water frequently. Could my well be bad


Sounds like you have a bad pressure tank and the tank is waterlogged..... if it has a bladder in it, you can press the air valve on the top, and if water comes out, the bladder is torn and the tank needs to be replaced... if is not a bladder tank, then you might need to have a new air switch installed.

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.

The pump goes on and off repeatedly


The pump should only run if you are using water. If you have a leak it will cycle on and off. If it only cycling fast when you're using water, you may need an expansion tank, sometimes referred to as a bladder tank for newer style. If you have a "bladder" tank , the bladder may be leaking and lost it's air charge. This bladder will have an initial air charge, and when the pump runs it will compress the bladder even further. When the pump shuts off the bladder is compressed. When you begin to use water, mainly low flow like one faucet, the bladder will begin to expand expelling the water from the tank until the pressure drops below that of the pump pressure switch. This makes the pump start and stop fewer times.

How do you stop a 12 volt water pump from short cycling when the outlet tap is on


Is this in a camper? You can either increase the flow to match that of the pump, or install a "bladder" tank in your plumbing system. A small air bladder tank is not too expensive. You charge it with a min of air pressure. When the pump comes on, it will pump the water, and this will compress the bladder raising the pressure in the bladder. When you begin to use the water, the bladder tank will begin to supply the water, when the pressure drops sufficently enough for the pump to come on the cycle will repeat, allowing the pump to start and stop with a delay in between instead of off-on-off-on etc.

The lower lumbar support on the driver seat will not hold air. 1994 ford explorer eddie bauer.


the air lumbar is an air bladder in the seat that is inflated by an air pump. Either the Check valve in the pump has failed and not holding air in the baldder, or the bladder has cracked and is leaking. May be possible to find another seat at a junk yard that is the same as yours. Replacing the entire seat is simpler then replacing just the bladder and pump assembly.

Air in lines


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

What is advantage of two tubes over one?


see friend .
we have two tubes .
1 one is for pumping the air so bag fills up.
2second contains the tube for telling pulse rate .
it is easy as we have systolic as well as dystolic pressure.
through two tubes we can have better reading.

Tank bladder has hole in it in the pressure tank


Turn off pump, open the tank water valve and let water out, now try and fill tank with air, if the bladder is bad the air will come out the valve, if no air, just fill it to 40psi and you should be good to go.
Bad bladder means you need to buy a new tank. Hope it just lost pressure and its ok.
