If the pump is primed, water will come out of the tank when the pump is running. It make take a little time for the tank to fill, but you should hear the pump making some noise. An un-primed pump just makes a motor noise, not very loud.

We emptied the water out of our WM6 pressure tank in order to check the pressure. However now that the tank is empty we get no reading from air fill valve.
No water = no pressure. The pump fills the tank with water putting pressure against the bladder inside. Start the pump until it shuts off. Check your tank pressure. Set the tank pressure to 2psi lower than the cut-off pressure of your pumps own cut-off pressure. A tank is used to give water pressure long enough for the pump to start and build it's own pressure. When you stop using water, the pump refills the tank. Ready for the next time you turn on the faucet.

Well Pump Problems The Water Well Tank
2811e7c.jpgOne of the common problems with having a well for you water supply is that you have the maintenance of the water pump and the related things that are necessary to make that all work. One of the most important parts of that system is the water well tank or the water pump tank. This tank is what keeps the well pump from having to turn on and off every time you draw a few drops of water.

In the past the tanks were made with an air valve that injected just a bit of air into the tank every time the pump started. This helped to keep some air in the tank and also gave the annoying problem of air coming out of the faucet at times. To make this better well water pump tanks are now made with a diaphragm that separates the air from the water.
This keeps the water cushion trapped inside the tank. That is great and makes the well tank virtually maintenance free as long as there are not holes in the rubber bladder that separates the water and the air.

There are some easy ways to tell if your well pump tank is not working the way that is should work. And also here are some things that you can do to maximize the capacity of the tank.
  1. Drain all the water pressure out of your system. Then check the air pressure in your tank and adjust it to 2 PSI below the cut in pressure of your pump.
  2. Make sure that your pressure switch is giving you 20 PSI differential between the cut in and the cut out of your pump.
  3. Make sure that your tank is big enough to give you at least 2 minutes run time when your pump starts till it stops.

Now for pressure tank not working
  1. The pump starts and stops rapidly while you are drawing water. This means the bladder has failed in the tank and you have no air in the pressure tank. Replace your pressure tank.
  2. You get a slight hesitation as you are drawing water before the pump. This means that you have too much air in the tank and you need to release some air or increase the cut in pressure on the pressure switch.
  3. If in the summer time you see condensation more than halfway up the side of the tank then you have a bad tank. The tank should never be more than about half full of water. Replace the well pressure tank.

One note to consider. If you are not drawing water and your pressure drops rapidly when the well pump shuts off then it is NOT a pressure tank problem, it is a problem with the check valve in the pump.

This should give you a basic trouble shooting guide to your well water tank or water pressure pump tank.

How does a home well water system work?
Deep well.
Pressure valve located on front of above-ground-storage-tank will turn pump on-off depending on amount of water pressure inside tank.
When water is consumed inside home, the pressure valve responds to the lower pressure and closes electrical contacts... sending electricity to water well pump located deep underground.
The pump turns on and lifts water through a pipe into the above ground storage tank.
When the tank is full of water, the pressure valve senses the higher pressure and turns off electricity going to pump
Pump shuts off.
There is a one-way check valve on the water line going down to pump, and this keeps water from flowing back down into well.
The above ground tank maintains water pressure for the house.
When pressure is reduced by taking a shower, the pressure valve turns pump on again, and cycle repeats.

Working pressure
Putting 60 lbs. of pressure in the pressure tank is not the answer.

First determine that the pump is working correctly, Open the drain valve and see if you get a good flow of water. If you do then OK, the pump is working. If you are not getting a good water flow from the drain valve, then the pump is not operating correctly - maybe a bad foot valve. Next open the drain valve and watch the water pressure gauge, and note at what pressure the pump kicks on ( that's the cut-in pressure), and when it kicks off ( that's the cut-out pressure). Most pumps are set to operate at 20-40 psi, or 30-50 psi. The cut-in and cut-out pressure is set by the water pressure switch.The pressure in the water tank has to be set 2 psi BELOW the cut-in pressure of the pump. That is, if the pump has a 20-40 psi differential, then the tank has to be pre-charged to 18 psi.

To pre- charge the pressure tank , the pump has to be shut off. The Tank needs to be emptied (drained ) of water. The air pressure is then set to 2 psi BELOW the cut-in pressure. If water escapes from the air valve, the bladder in the tank is ruptured, and a new tank needs to be installed.

So, first make sure the pump is working.
I WOULD RELIEVE MOST OF THE PRESSURE IN THE PRESSURE TANK TO ABOUT 20 PSI BEFORE CHECKING THE PUMP, AND PRCEEDING WITH THE PRE-CHARGE OF THE TANK.

How does pressure tanks work
Pressure tanks do just that in a water system. They create pressure for water to flow when the water pump is on the off cycle. A manifold is plumbed into the tank from the main line coming from the well. The main water line continues to the house plumbing from the manifold. So it's line from pump to manifold - to tank, and from manifold to main into house. The manifold also has tappings for the pressure gauge and the pressure switch. The pressure tank creates water pressure. The water does not flow through the tank. Pressure tanks also have to be 'tuned' or adjusted to the low end pressure set by the pressure switch. Actually the tank pressure needs to be set 2psi below the low end pressure. Most residential water systems are set to operate between 20 -40, or 30-50 psi, which is set by the pressure switch, which in turn , turns the water pump on and off. So if a system operates between 20 and 40 psi, the pre-charged pressure of the tank should be 18 psi. Pre-charged means the tank is drained of water with the water pump OFF. The tank pressure is then checked adjusted by way of the air valve on top of the tank ( A tire gauge works). Pressure tank mainfolds are a common plumbing part.

What is a water pump and do I need one for my freshwater aquarium?
Water pumps providecirculation in your tank without providing a current. It is generally recommended to have a waterpump to keep the water from being stagnant and to assist the filter inaccessing all the water in the tank. Thelarger the tank, the more necessary a water pump is.

Pump clicks on and off every time you use water or flush tiolet
This is and indication of a water logged pressure tank. Turn pump off, drain all water from tank, add air to well tank, 2psi below cut in pressure IE: 30-50 switch the air charge should be 28psi in well tank. Make sure water valve after tank is turned off before adding air, so it is not lost before turning pump back on. If problem persists replace well tank.

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.

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!
