Each of our technicians went through rigorous training so we can guarantee that you will be receiving the proper service. We are also insured and supply a warranty for our parts for five years and up to twenty years on an re-piping or sewer replacement. Call us now to make your appointment!

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

Wells and Pumps questions, answered by experts

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

Well pumps need power to run, so they can’t function without electricity. If your power shuts off, there can sometimes be enough pressure in the water tank to allow for a lucky flush or a bit of tap water—but this won’t last long. It’s a good idea to have a backup generator or an alternative power source like solar if you’re worried about losing power.

The precharged pressure tank should start at around 28 psi. The two pressure settings of note are the cut-in and cut-out pressure. The well pump starts when the tank reaches the minimum cut-in pressure. It turns off when the tank reaches the maximum cut-out pressure. The desired water pressure in the household is usually a few psi above the cut-in number. The difference between the cut-in and cut-out pressure settings should be 20 psi. Typical settings for household applications include 20/40, 30/50, and 40/60.

Frozen well pipes make themselves known quickly, as your faucets slow down to a trickle or shut down completely. If you notice a serious reduction in flow in the winter from toilets, showers, kitchen faucets, and other plumbing fixtures, a frozen pipe or two is to blame. Another tell-tale sign is frost or ice on exposed pipes outside. 

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.
