Pressure Tank Replacement in Nokesville, VA

That clicking in the basement is worth a call

Most people in Nokesville never give the pressure tank a thought until the pump starts clicking on and off every few seconds. You rinse a glass and the pump kicks on. You shut the tap and it kicks off. Then it does it again. That pattern is called short cycling, and it is the most common reason we get called for pressure tank replacement in Nokesville.

The tank’s job is simple. It holds a cushion of air above a bladder full of water, so the pump can rest between runs. When that cushion is gone, the pump has nothing to lean on. Every drop you use makes it start again, and every start wears on the motor and the pressure switch.

Our shop sits here in 20181, so most homes in town are a short drive for us. That matters when a small tank problem is about to turn into a bigger pump problem.

Signs your tank is failing, not your pump

A tank and a pump can cause symptoms that look alike, which is why we check both before we recommend anything. These are the signs that usually point at the tank:

The pump turns on and off rapidly, even for small draws of water.
Pressure at the shower swings from strong to weak and back again.
The tank sounds dull and full all the way to the top when you knock on it.
Water, not air, comes out when you press the air valve on top.
Rust, a drip, or a damp ring on the floor at the base of the tank.

If you have low pressure with no clicking at all, the cause may be somewhere else in the system. Our article on low water pressure on a well walks through the other possibilities.

A safe check you can do yourself

You can check the tank’s air charge with a regular tire gauge. Turn the well breaker OFF first. Then run a cold water tap until it stops flowing, so the tank is empty. Find the air valve on top of the tank (it looks just like the valve on a car tire) and take a reading.

The reading should sit about 2 psi under the low number on your pressure switch. On the most common 40-60 setting, that is around 38. If the number is much lower, or water comes out of the valve, the tank is likely losing air or the bladder inside has failed. Our guide on checking your pressure tank pressure has more detail, and if you do not know your switch setting, we can help you figure it out on the phone.

Please stop there. Do not open the pressure switch cover or touch any wiring. That part is ours. When you are done, turn the breaker back on and write down the number you saw. It helps us a lot when you call.

Farm properties and holding tanks

Nokesville has a lot of rural and farm property, and those setups ask more of a water system. A house, a barn hydrant and a garden line can all pull from the same well. Some properties also have a holding tank that stores water before it goes to the house. When one of those tanks wears out, the whole property feels it. Pressure drops at the barn first, then the house starts acting up.

We replace both pressure tanks and holding tanks, and we look at how the property actually uses water before we pick a size. A tank that is too small for the demand can make a pump short cycle even when nothing is broken. If a barn or pasture needs its own water point, we also install hand pumps and hydrants.

Questions we hear a lot

How do I know if my pressure tank needs to be replaced?

The most common signs are a pump that clicks on and off every few seconds, pressure that swings up and down, or water coming out of the air valve on top of the tank. Rust or a leak at the base is another sign. We can check it for free and tell you whether it needs replacing or just needs air.

Why does my well pump click on and off every few seconds?

That is called short cycling, and it usually means the pressure tank has lost its air cushion. Without that cushion the pump has to start every time you use a little water. It is worth fixing soon, because constant starts wear on the pump and switch.

How quickly can you replace my pressure tank in Nokesville?

Our shop is in Nokesville, so we are a short drive away, and we install Well-X-Trol tanks. Call 703-791-3981 and we will tell you what the day looks like.

Is a waterlogged pressure tank bad for my well pump?

Yes, over time it can be. A waterlogged tank makes the pump start and stop far more than it should, and those extra starts add wear to the motor and the pressure switch. Replacing the tank is usually much cheaper than replacing a pump early.

What should the air pressure be in my well tank?

With the well breaker off and the tank drained, the air charge should be about 2 psi under your switch's low setting. On a 40-60 switch, which is the most common, that is around 38 psi. You can read it with a tire gauge at the valve on top of the tank.

Does a farm in Nokesville need a bigger pressure tank?

Sometimes. A property that feeds a house, a barn and hydrants can use more water at once than a tank sized for a house alone was meant to handle. We look at how you actually use water before recommending a size.

Do you replace holding tanks too?

Yes. We replace both pressure tanks and holding tanks. If you are not sure which one you have, describe it when you call 703-791-3981 and we can usually tell you.

Do you charge to come look at my pressure tank?

No. Diagnosis is free within reason, and Nokesville is our home base, so there is rarely a question of distance. We will tell you what we find before any work starts.
