Tips For Priming Your Well's Water Pump

Construction & Contractors Blog

If your home's well is fitted with an above-ground pump, it's important that the system maintain its prime to keep the water flowing. Without a primed pump, the system runs dry, loses its suction and is unable to draw water from the well. In order to fix this, you'll have to manually prime the pump if it stops working. Here's a look at what you need to know to prime your well pump. 

Gather Water

In order to prime the pump, you'll need to have access to a couple of gallons of water. In most cases, 2-3 gallons will suffice. Unfortunately, if your well pump isn't working, it can be challenging to obtain this water. You can go to the store and buy a few gallons of water, but you wouldn't necessarily have to. You can connect a small hose to your hot water tank's drain valve and fill a couple of gallon jugs with water from the hot water tank instead. Just make sure you use clean containers to do it.

Shut Down the Power

You'll have to shut down the pump before you can get started. Turn the power off at the primary switch, that way the pump doesn't automatically engage when you fill it with water. Then, turn on a water tap in the house for a minute or two to purge any pressure from the lines.

Prime the Pump

Locate the priming plug on the pump. It's a hexagonal or square metal plug, and it should screw into the top of the pump. Remove it with a combination wrench. Then, put a funnel into the hole so that you can be sure that all of the water goes into the pump. Pour the water into the funnel to fill the impeller chamber and well pipe. Once the water starts to flow out of the hole, you can stop filling. Remove the funnel. Wrap the plug threads with a little bit of plumber's tape to help ensure that the system builds suction.

Restore the Power

Turn the power back on to the pump. Watch the pressure gauge on the pump to be sure that it rises up to a steady pressure level. Also, listen to the pump's operation. You should hear the raspy noise of air in the pump quickly give way to a quieter, muffled sound as the pump fills with water and functions properly. If both of these things don't happen, you'll need to repeat the priming process.

Once the pump is primed, run your interior faucets for a few minutes. This will flush the priming water out of the system. If you can't restore the prime, talk with a pump service technician (such as one from All's Well) about troubleshooting the issue.

All About Building a Home

Welcome to my website. I'm Albert Frost. Besides my dad, one of my biggest role models was my uncle Rick. He was a construction contractor who would let me come on his construction sites and also taught me everything he knew about building homes, including how to install hardwood flooring and add insulation. I always wanted to grow up to build houses like my uncle. I used to help my uncle with a lot of the grunt work needed to make a home a reality. But then I hurt my back playing football. Until I heal completely, I'm going to devote as much of my time as possible to teaching others about various construction topics I'm interested in.
