"Zac called me within 5minutes of me speaking to the call center. He arrived alone when he said he would. We have a well cap that is underground so it must be dug up. Unfortunately I could not remember the exact location so he dug for more than an hour. Finally my husband said to move down the path more Zac found my sons helped remove the 3 foot round concrete cover and pull the pump. Zac did all the work needed and put the pump back . He did above and beyond for us in the rain. Would definitely recommend them."

"Zak is incredibly professional and the best plumbing technician we have had work in our home, and we have tried many over 30 years living in this house. Mary was also professional and an excellent communicator, making sure everything was arranged and we always knew the status. We required services more than one day, and everything was handled well and cleaned up spotlessly. Zak is intelligent, thorough and explains everything well. We highly recommend Beacon Home Services."

"Fantastic service. This is the second time we've hired R & G Water Systems. Both times we had an issue in the middle of the night and they were able to send someone out first thing in the morning. They replaced our well pump the same day (within a few hours of calling actually). This went as smoothly as the first time we hired them and would definitely continue to use them."

"We had a well pump go bad and I called Tri-County Pumps. They were busy from the weekend overflow of work, but said they would try to get someone there as soon as they could. They had someone here the very next morning, and the pump was replaced by that afternoon. We have water again, and I am SO happy with the service I got from Kenny and Shawn. I would Highly recommend them 100%. Thanks Tri-County and Kenny/Shawn!"

"One unit was fine. The heat pump unit needs some new parts as it is 11 years old and sitsc in the roof under the southern sun and is just getting worn down. So Rob from Sila recommended the parts that need replacing. Very good company that I have used for that to perform these twice yearly checkups. Highly recommended."

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.

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.

Yes, you can oversize a well pressure tank without harming your well system, as there are no major risks involved. The primary advantage of a larger tank is an increased lifespan due to less frequent pump cycling. Fewer startups and longer, slower runtimes mean less wear and tear on the system and can help conserve energy. The main drawbacks are the higher upfront cost and the larger amount of space required for an oversized tank. While not necessarily a bad thing, it is often more efficient to select an appropriately sized tank to save money and space.

Reduced water pressure, strange noises, or air sputtering from faucets.

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