Residential and business water treatment systems. Water softeners, UV lights. We will analyze your water for contaminants such as chlorine, low pH, iron, bacteria, and devise a system to suit your needs. Treat your water from the source, as it enters your home, so whether you are drinking it, cooking with it or bathing in it, your water is pure.

"The process was quick and easy. I just provided a water sample. It was determined that I had high levels of chlorine in our drinking water. I was able to solve my water problems with only one filter. Why did I wait years to have this done? Now I can be confident that our water is safe. Highly recommended."

CP has been providing quality home warranty products since 1998.

"The person performing the service had to make several trips because one of the "new" parts turned out to be faulty. I found both Complete Protection and their local repair contractor to be both very responsive and totally professional at every stage of the repair process."

Wells and Pumps questions, answered by experts

Another common question is, what pressure should your well tank be set at? The standard rule of thumb is to set your well tank’s pressure at 2 psi below the cut-on point of your pressure switch. So if your well is set up for a high cycle of 40/60 psi, your pressure should be set to 38 psi. If you use a low setting of 30/50 psi, you would set the pressure to 28 psi.

Normally, when your well pump turns on or off, you’ll hear a small click. This isn’t anything to worry about, but it can be a problem if it’s clicking continuously. This can indicate that the well pump is short cycling—the pump continuously turns on and off.
