How to check and adjust your well tank’s pressure?

The good tank is a vital part of your home’s plumbing system. It stores water until you need it, then releases it into your house through your faucets. If the pressure inside your good tank drops too low, you might experience problems such as leaks or slow flow.

You should check your well-tank pressure every month because it can change over time. This article explains how to check and adjust your good tank pressure.

How do well pressure tanks work?

A well tank works like a reservoir. When you turn on your tap, the water flows from your well tank into your house. As long as there is enough pressure in your well tank, your taps will run smoothly. However, if the pressure in your well drops too low, water may leak out of your pipes.

It is important to keep your well tank full so that it has sufficient pressure. If your well tank runs dry, your water supply could be cut off. In addition, you may not get enough water pressure when using your shower or washing dishes.

What pressure should my well tank be set at?

The U.S. Department of Agriculture recommends that your well tank be set at 12 psi (pounds per square inch). This level of pressure keeps your water flowing freely without causing damage to your pipes.

It is best to maintain a constant pressure in your well tank throughout the day. For example, if you live near a lake, you might want to increase the pressure during the summer months when more people are using their showers and toilets. Conversely, you might lower the pressure during winter months when fewer people are using hot water.

How often should I check my well tank pressure?

Checking your well tank pressure monthly is recommended. If you notice any changes in your well tank pressure, contact your local plumber right away.

It is important for homeowners to know what they can expect from their well tank. A properly functioning well tank provides safe, reliable service.

How to Check a Well Tank’s Pressure?

If you suspect a problem with your well tank, call your local plumber immediately. Plumbers can inspect your well tank and provide advice about how to repair it. They also can recommend an alternative solution such as installing a new well tank.

Determine your Cut-in Pressure

The cut-in pressure is the minimum amount of pressure needed to keep your well pump working. When you turn on your well pump, it begins pumping water into your well tank. As long as there is enough pressure in your well, your well pump continues to work.

When you first connect your well to your home, the cut-in pressure may be higher than normal. This occurs because the well has not been used for some time. To determine your cut-in pressure, turn on your well pump and leave it running for 30 minutes.

During this period, the well pump should continue to operate without interruption. If the well pump stops operating, then the cut-in pressure is too low.

Turn off the Pump

If you find that your well pump does not run when you turn on your well, the cut-in level is too low. To increase the cut-in pressure, add more gravel to your well.

Gravel is added to wells to prevent sand from entering the well. Sand enters the well through cracks in the ground around the well.

Drain the Tank

After adding gravel to your well, check the level of water in your well tank. If the water is still full, then no additional gravel was required. However, if the level of water in the well tank is very low, then more gravel needs to be added.

Check the Tank’s Pressure

Before using your well pump, check the pressure in your well tank. The pressure should be between 10 and 15 pounds per square inch (psi). If the pressure is lower than 10 psi, add more gravel to raise the pressure.

Adjust the Pressure

You can adjust the pressure in the well tank by adjusting the flow rate of the well pump. A flow rate adjustment allows you to control the amount of water pumped into your well.


Well tanks are important parts of any well system. You need to maintain them properly so they will last many years. Contact your local plumbing company to schedule regular maintenance checks.
