"I had an excellent experience with Polar Plumbing and would confidently recommend them to anyone in need of plumbing services. From the first phone call to the completion of the job, their team was courteous, efficient, and highly professional. The technician arrived right on time, quickly diagnosed the problem, and clearly explained what needed to be done. I appreciated the honest communication and the transparent pricing?there were no surprises, and the work was completed within the estimated time frame. The quality of the workmanship was outstanding. Everything was done neatly and with care, and the plumber made sure everything was working perfectly before leaving. They even cleaned up thoroughly afterward, which I really appreciated. It?s rare to find a company that combines reliability, skill, and customer service so seamlessly, but Polar Plumbing absolutely provided."

"Our old system was completely shot. We weren't sure what the problem was but Gary came to our home on short notice, diagnosed the problem accurately and quickly and gave us a cost estimate with a repair date that was very quick as well. They arrived to do the repair, cleared the area needed for the work, removed the old tank and replaced it with a modern one, pulled the entire well pipe and pump which obviously was in terrible condition. They then installed a top line pump and new pipe. The new system worked flawlessly and provides pressure that we have not enjoyed in years. We are incredibly grateful to the work the crew put into completing our repair and replacement. They worked long hours and were cheerful and well-mannered through all of it.? I highly recommend Water Flow Systems. They are the best!"

"Andrew from Plumbing in Pink checked problem, ran dishwasher and determined that the issue was not a plumbing problem but an appliance problem. He suggested that we check with the home builder since the dishwasher was new. Andrew was very knowledgeable, helpful and professional. I would definitely call Plumbing in Pink again if I had any plumbing issues."

Wells and Pumps FAQs, answered by experts

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.

Yes, a bigger well pump can increase water pressure—up to a point. If you currently have a well pump of 8 GPM, you might notice a pressure boost when you go up to 10 GPM. However, overshooting significantly (going up to 15 GPM for an 8 GPM home) can strain your well system and result in things like burst pipes that can decrease your water pressure and make for costly repairs.

No, a larger well pressure tank will not increase your home's water pressure by itself. Water pressure is determined by the pressure control switch on the well pump.

However, a larger tank does offer other benefits. It can store more water, which allows you to run water for longer periods before the pump needs to turn on. This reduces how often the pump cycles on and off, leading to less wear and tear on the pump and the entire well system. Consequently, a larger tank can help extend the life of your equipment and may prevent future pump issues that could affect water pressure.

If your goal is to increase water pressure, consider these alternatives:

  • Adjust the pressure settings on your tank to a higher PSI (pounds per square inch).

  • Replace your current pump with a model that has a higher flow rate, measured in gallons per minute (GPM).

  • Have a professional install a water pressure booster pump in your plumbing system.

  • If you experience pressure fluctuations, consider upgrading to a constant pressure system.

A leaking well pipe is quite different from if the well itself is leaking. To seal a leaking well, pour a cement mixture or bentonite into the space between the well casing and the borehole wall. The heavier cement collects at the bottom to form a solid seal, pushing lighter materials like mud and fluids up toward the surface. Professional well installation companies have the equipment to do this properly. 

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.
