Pressure Tank Replacement in Prince William County VA

Pressure Tank and Holding Tank Replacement

Short cycling, sputtering taps or a tank that sounds full of water? Oasis Well Service handles pressure tank replacement and holding tank work across Prince William, Fauquier and nearby counties, installing Well-X-Trol tanks balanced to your switch setting.

What your pressure tank actually does

Your pressure tank holds a cushion of air above a store of water. The air pushes water to your taps so the pump does not have to start every time you rinse a glass. When the tank is healthy, the pump runs in longer, calmer cycles. That is easier on the pump, the switch and your electric bill.

A holding tank works alongside some systems to store extra water. Both kinds wear out, and both can quietly shorten the life of your well pump when they fail. A tank problem caught early is usually a much smaller job than the pump damage it can cause later.

Signs you need pressure tank replacement

Short cycling

Short cycling means the pump clicks on and off every few seconds while water runs. You may hear the switch chatter or see the gauge bounce. It is one of the hardest things you can put a pump through. Every start heats the motor and wears the switch contacts, so a pump that short cycles all day ages much faster than it should.

A waterlogged tank

A waterlogged tank has lost its air charge, so it fills with water and has no push left. Tap the top and bottom. If it sounds full all the way up, that is a clue. Some tanks leak air through the valve, and older tanks can fail inside. Once the bladder or diaphragm fails, adding air only helps for a short while.

Other clues

Pressure that surges and drops at the shower
Air spitting from faucets
Rust, sweating or a leak at the base of the tank
A pump that seems to run more often than it used to

A check you can do yourself

You can safely check the air charge with a tire gauge. Never open the pressure switch cover.

Turn the well breaker OFF.
Run a cold tap until the water stops.
Check the schrader valve on the tank with a tire gauge.
On a 40-60 switch, air should sit around 38, about 2 psi under the low number.

Our step-by-step guide to checking pressure tank pressure walks through it. If the tank will not hold air, it is time for a new one. If the reading looks fine but the trouble continues, the cause may be the switch, a leak or the pump, and that is when a proper diagnosis helps. See our post on low water pressure on a well for other causes.

How we replace and balance the tank

We install Well-X-Trol pressure and holding tanks. Then we balance the tank’s air to your switch setting, whether that is 30-50, 40-60 or 60-80. That balance protects the pump and the new tank. We also look over the switch, gauge and fittings while we are there. If we notice a leak or a worn part nearby, we point it out and let you decide what to do. We clean up and make sure the system runs through a few full cycles before we call it done.

Questions we hear a lot

What does short cycling mean on a well system?

Short cycling is when the pump turns on and off every few seconds while water is running. It usually means the pressure tank has lost its air charge. It wears out a pump fast, so it is worth fixing soon.

How do I know if my pressure tank is waterlogged?

A waterlogged tank has little or no air left, so it acts like a plain pipe. Common signs are short cycling, pressure that jumps around, and a tank that sounds full of water when you tap the top. A quick air check with the power off will confirm it.

What should the air pressure be in my well pressure tank?

With the well breaker off and the water drained down, the air should sit about 2 psi under the low number on your switch. On a common 40-60 switch, that is around 38. Use a tire gauge on the schrader valve.

Can I just add air to my pressure tank instead of replacing it?

Sometimes. If the tank simply lost some air, balancing it can solve the problem. If it keeps losing air or fills with water again, the bladder or diaphragm has likely failed and the tank should be replaced.

What brand of pressure tank do you install?

Oasis Well Service installs Well-X-Trol pressure and holding tanks. We set each one up and balance it to your pressure switch setting before we leave.

Can a bad pressure tank damage my well pump?

Yes. A failed tank makes the pump start and stop far more than it should, which adds wear and heat. Replacing a tank is usually far easier than replacing a pump, so it pays to catch it early.

What is the difference between a pressure tank and a holding tank?

A pressure tank uses an air cushion to push water through the house between pump cycles. A holding tank stores extra water for some systems. We service and replace both.

Do you replace pressure tanks in Fauquier County?

Yes. We cover Fauquier, Prince William and the surrounding counties. Call 703-791-3981 and we will talk it through, and we can often start the diagnosis on the phone.
