We are a full service Excavation and Trucking Company with 30+ years of experience. Specializing in Complete Septic System Installation and Repair. New or Failing System we perform perk and have Design Engineers we work with your particular project. Demolition of any Building and removal of debris. We do not perform septic pump outs.

"Septic tanks were left exposed, site was a mess, and vent pipe was not at the required height. We talked with him a month before we anticipated water connection, so he knew our timelines. We attempted to contact him every day for a week to schedule final inspection after water was connected, but got no response. It took two emails from the city for him to sign the certificate of compliance."

We Are a full service septic Company offering installation, repair, maintenance & inspections.

"It’s hard to leave a good review when your request for service call was not responded to. When we first moved to the area our real estate agent scheduled Buttormores to do our first clean out, no problem, it went down without a hitch. 4 years later I need another clean out, I called and left a message with respect to my location and service needs, I even stated that he had done the clean out here in the past. No call was returned ever, I guess this contractor is to big for his own britches. O e thing I can’t stand when calling for service is a business that doesn’t even have the common curtesy to return phone calls. I will never call again, and will never recommend this contractor to anyone! Shame on you Buttermore!"

FAQs for septic system installation and replacement projects in Montville, CT

A failed backflow preventer can let contaminants seep into your drinking water. Watch for leaks around the valve, sudden pressure drops, slow drains, musty odors, or rusty-looking water. If you spot these red flags, call a licensed plumber right away for an inspection and repair. Keeping up with annual tests is the best way to catch problems early and protect your home’s water supply.

You might need a backflow preventer if you have features like irrigation systems, pools, or other water elements that could contaminate your water supply. Having a backflow preventer will help protect the safety of your water supply. Due to higher contamination risks, commercial and industrial properties are required to have backflow preventers.

Backflow preventers and backwater valves serve distinct roles in protecting your home’s water systems. A backflow preventer stops water from reversing in your main supply to keep clean water uncontaminated, while a backwater valve is integrated into your drainage system to block sewage backup during heavy rainfall or overflow. Each device is designed to address specific flow challenges and safeguard your property.

The time it takes to install a backflow preventer depends on the type of system. A plumber can install a simple backflow preventer, like those for a garden hose or appliance, in less than an hour. Installing a backflow preventer for a complex system can take up to a full day.

If you’re already breaking up your floor to install a sewer backflow preventer, it’s a smart move to tackle other plumbing upgrades while you’ve got easy access to the pipes. This is a great time to think about adding rough-ins for a basement bathroom or making other plumbing improvements. Once the floor is sealed back up with concrete, making changes later can be much more complicated and costly.
