Our team has over 90 years of combined experience providing reliable radon mitigation, water filtration, and well pump services and solutions to the Fairfield, New Haven, Hartford and Litchfield Counties of CT. Want to create a healthier and safer home environment? Call CT Radon and Well Water Solutions to schedule a no-cost radon mitigation or well water treatment estimate. We also offer cost effective well pump repairs throughout Fairfield, New Haven, Litchfield, and portions of Hartford and Middlesex counties. Schedule yours today!

"I would not recommend. I am a real estate agent and contracted this company to install a radon mitigation system in a home prior to closing based on a high radon level test during inspection. I met the company rep at the property and he quoted a system later that day after inspecting the home. The system was installed two weeks later and a retest came back more than double the level of the initial test. This company claims they have a warranty to cover any system modification to get the levels below 2.0. The company sent a crew back out twice and yesterday said the slab is too thick for the system they installed, the hole the installers drilled is too narrow and the home is in a flood zone. We knew the home was in a flood zone, but this company never asked about that and did not do any due diligence prior to installation. They are refusing to honor their warranty and are now quoting a different system that is much more costly. Can?t recommend."

"Three years later we're still dealing with the fallout from Garrity's shoddy work. We hired them to install a pump and sensor system to supply water from a new dug well. They consistently cut corners and over-charged us. We have had to hire another company to fix the issues they created (for instance, the pump controller shorted for the second time last week, and each replacement has cost > $1,500)."

Septic Tanks questions, answered by experts

The efficacy of a drain field depends on a wide variety of factors, though a well-maintained one can last as long as 40 or 50 years. Of the different types of septic tanks on the market, concrete and plastic tanks tend to last the longest—upwards of 40 years if they’re pumped regularly—while steel tanks have a tendency to rust over time and may need to be replaced after 15 or 20 years.

Most septic tanks need to be emptied every 3 to 5 years, but it’s a good idea to monitor the fill levels of your septic tank all the time. You can do this by installing a pressure level sensor to detect the internal tank pressure, or by having a septic tank company perform an annual inspection to let you know when you’ll need to pump the tank.

The best way to keep a septic tank clean is to hire a local septic tank cleaner to inspect and pump the septic tank every three to five years. Be sure to only flush human waste and toilet paper down the toilet, and don’t pour grease, oil, fats, coffee grounds, or food scraps into your drains.

Soda, coffee, and other soft drinks are highly acidic. This affects the pH in septic tanks, causing them to require more frequent pumping. However, a vast majority of people don't need to worry about septic system disruption. Pouring out the occasional flat soda doesn’t affect septic systems to the same degree as the high-volume dumping from restaurants and convenience stores.

If you’re maintaining your septic system, your drain field should last around 20 years. However, it’s important to get it inspected every two to five years to help your system last as long as possible and make sure it’s in safe, working order. Contact a septic maintenance company in your area for a quote.
