"While other companies spent years trying to figure out what was wrong with my system and after much money spent on â fixesâ , Eastern Water found a small piston dysfunction and the fix was simple and not expensive. I plan to switch to them for my routine maintenance. Additionally, they were responsive, efficient and reliable. The service person was very knowledgeable and explained everything to me."

"Woke up one morning and had no water at all. Turned out the well pump had gone bad and needed to be replaced. They came out, replaced the pump and got the water running again. Haven’t had a problem with it since. Really glad I called them and would definitely use 1&Done Plumbing again."

"Ralph was excellent. He called within minutes of me submitting the Angies List request....... and came the very next day to fix our problem. He was pleasant, down to earth, honest and did the repair quickly, solidly, and for the money he’d estimated. Overall we were very very happy with our choice to go with Ralph!!"

"Ralph was awesome!!! Friendly, knowledgable and heartfelt. My well pump stopped working 11:30 PM on a Saturday Night, Ralph replaced my well pump on Sunday. The the same day I posted the request. My well pump and pressure tank was twenty years old. I learned a lot too! He answered all my questions from my YouTube research. He walked me through the process and let me know what was going on. Most of all, the pricing was reasonable and I am happy with the work."

"The tech who worked for the company seemed to have experience with the problem and knew when they went down into the basement what the problem was. E.Garrity rep came out that same night I called and said needed a new water pump. Next day the pump was installed and we had water once again, Thank you for the fast service. William Safee Jr."

Wells and Pumps FAQs, answered by experts

A well pressure tank is located between the well and the well pump, and it stores your water under pressure so that the well pump can eventually do its job. The well pump is activated whenever you turn a faucet on—it pulls the water from the tank into your home. Both are vital parts of a complete well water system.

If your well pump is running continuously (meaning without turning off or stopping), it's a sign that your well pump is starting to break down. The length of time your well pump should cycle is dependent on many factors, like the tank size, pressure setting, and even the amount of water in your well. Generally, your well pump should cycle, or go from running to not running every few minutes.

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

Most professionals recommend that a deep well pump shouldn’t run more than 10 hours consecutively before cycling off. Overworking the well pump beyond the recommended amount can prematurely wear out your pump and burn out the motor, which means replacing it more often than you otherwise should need to. Your well pump should also come with the manufacturer’s use and maintenance recommendations that are specific to the model.

DIY is not recommended due to safety and technical requirements. Hire professionals for accurate diagnosis and repair.
