You install a pressure tank anywhere on the delivery or pressurised side of a system. All pressure pump systems need a check valve (or 1 way valve) installed in the pipework. This can be installed on the suction side (as a foot valve or on the pump inlet) or just after the pump on the outlet. The check valve stops water flowing backwards and the pressure dropping when the pumps turns off. This allows a pressure pump to build up pressure and let the automatic switch turn it off.

A pressure tank can be installed anywhere after this check valve. This means that when all the taps in the system are shut, then the pressure in the system builds. When the water pressure in the system builds to beyond the air pressure sored in the tank, then the air starts to compress and the water fills up the wet side of the tank. Once the wet side of the tank has compressed the air as much as it can, then the pressure builds a little bit more and then switches off.

You simply cut in a T piece or a tapping saddle into the outlet pipework and have a pipe or a piece of pressure hose across to the inlet of the tank. Some tanks (up to about 15L) are OK to mount on the pipe or on top of the pump. Once they get beyond this size, they usually have to be mounted on a base and most of the time they actually come with a base .
​
Pressure tanks are a cheap, simple and effective piece of gear that will help protect your pump and provide you with a good constant pressure and flow of water for whatever application you need.

Check for Clogged Pipes
Low water pressure could exist because you have clogged pipes with a build-up of hard water, sediment, or minerals. In this case, you'll have to clean out your pipes. Increasing the water pressure won't help, but it could cause water system damage if there are clogged pipes. Not only that, but you could spend a lot of time and money trying to change the pressure control switch (mentioned below) when that's not even the problem. That is why you must be certain that the problem is not a clogged pipe before trying something else. Next, check to see that all of the faucets and shower heads are also clean and clear of buildup that could be blocking water flow. If they're clogged, take the time to clean them off.

Install Contant pressure System
If you know clogged pipes are not an issue and you notice that whenever you're running water from more than one tap and the water pressure drops, the solution could be as simple as installing a constant water pressure system. This will keep your well water pressure constant, even when you use more than one faucet at a time.
Fortunately, a constant water pressure system is pretty easy to install, too. You can install it on the line where your water enters your home, usually in the basement. This can also be used if the height of your building is impacting the water pressure on the upper floors or if your water pressure tank and pump are too far away from the point of water use.

Adjust The Pressure Tank
Another solution is to adjust the pressure tank. Pressure tanks have gauges that will tell you how much pressure is flowing through your pipes. If it's below 40 psi, you might want to increase it. Just remember to not adjust it to above 60 psi because that could cause water pipe breakage, leaks, and switch failure.

To adjust the pressure tank, first turn off the circuit breaker, which supplies power to the well pump. Once that's done, locate the air fill valve on top of the pressure tank. This valve is much like a tire valve. To find out what the psi currently is, attach a tire pressure gauge to get the pressure reading.

Step 1 - Turn off Power to Well Pressure Tank
Before doing any type of work to the well pressure tank, it is important to make sure that the power is turned off. This should be done at the breaker box. Once you turn the breaker off, test the tank to make sure there isn't any power. Also, leave a note attached to the breaker letting others know that you are working on that item.

Step 2 - Drain Water from Tank 
Attach the garden hose to the drain at the bottom of the tank. It is usually located on the bottom edge of the tank. Simply attach the hose to the drain by screwing it onto the faucet-like outlet. With the hose on the drain and the other end leading into a bucket or out a door, open the valve. The water should begin to immediately drain from the tank.

Step 3 - Remove Air Regulator
Located at the top of your well pressure tank is the air regulator that shows how much pressure is in the tank. This can be removed with the use of a pair of adjustable pliers. Carefully remove it so that you do not damage it.

Step 4 - Remove Access Hatch
Located on the top of the pressure tank are a few screws that hold the access panel to the pressure tank. Loosen these screws and remove them. Lift the access hatch away from the tank and shine a flashlight into the tank.

Step 5 - Wipe Out Build Up
Anything with water is going to have some type of calcium build up within the internal workings of it. Wipe out the inside of the well pressure tank with a rag. If you can not remove some of the build-ups, use a piece of steel wool. Scrub the calcium deposits off the pressure tank and pipes.

Step 6 - Replace Access Hatch
Set the access hatchback onto the well pressure tank and tighten it down with the screws.

Step 7 - Replace Air Regulator
If the regulator looks like it is not working correctly, test it with an air pressure tester. If needed, replace it with a new one. Wrap some plumber's teflon tape around the threads and screw into the housing. Tighten it down with the pliers.
