"First there were a couple of delays due to COVID, the weather, and a truck broke down. The window guys were over 2 hours late. While excavating near the house, the workers “accidentally” broke our water main. This of course was our fault and cost us an additional $3000! Read your contract. There is a small clause about accidents not being their fault. Subsequently, we had no water for two days and a large plumbing bill from a plumber they sent. This may not be over."

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."

Septic Tanks questions, answered by experts

Recognizing signs of a failing septic system is crucial to prevent costly damage and health hazards. Foul odors in and around your home, slow drainage in sinks and toilets, or gurgling noises in plumbing fixtures can indicate problems with drainage. Lush, green patches of grass near the drain field or wastewater pooling on the ground are alarming signs that may indicate a leak in the system. If you notice any of these symptoms, it's vital to address them promptly to avoid more extensive and expensive issues.

Yes, states and municipalities require septic tank companies to be licensed, so an unlicensed  individual or company cannot complete a septic tank installation or alteration. Most municipalities also require licenses for septic tank pumping. You should always verify that the company you’re considering for your septic tank project is properly licensed, which you can do by using Angi’s licensing search tool. You should also verify that the company is fully insured to avoid legal issues should an employee be injured on your property.

Getting well water tested costs $100 to $350 if done by a pro. You can also buy DIY test kits for $20 to $100, but professional tests are more reliable. You can get a comprehensive well inspection, which includes advanced water testing, for $700 to $750, which you should do yearly anyway.

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.

The septic tank needs to be pumped at least every three to five years. If the septic tank is too small for the property, you might find it needs to be pumped more frequently, and during an inspection, a septic company may recommend updating your system to a larger septic tank. While 750-gallon tanks used to be standard, septic tanks with a 1,250-gallon capacity are now more common.
