"I need to share my experience with Clear All Rooter. I called them a few weeks ago to replace my 14 yr old water heater. I told them I wanted to use a water heater by Bradford and White. He quoted my $2800.00 for a 50 gallon water. I did not do my due diligence and just said go ahead and replace it. I was kind of stressed at the time. Only later did I realize that the heater cost $1020.00 and I ended up paying $1800.00 for installation which I consider a massive rip off. It is all my fault for not asking upfront about product cost and labor. Dont make the same mistake. I ended up making a home improvement loan to pay it off over the next two years. They did a great job of installation but I dont think it was worth $1800.00. I am a veteran who lives a modest lifestyle and I dont appreciate this type of treatment. Please beware when you use Clear All Rooter. This could happen to you."

Water main install, replace or repairs FAQs

Whether you need a permit depends on your local regulations. Always check with your municipality before beginning the installation. Most contractors will handle the permitting process for you.

If your backflow preventer fails, dangerous contaminants can enter your clean water supply, posing serious health risks. You may notice signs like visible leaks, a sudden drop in water pressure, slow drainage, unpleasant odors, or discolored water. If you experience any of these symptoms, contact a professional immediately.

Signs of a failing backflow preventer include visible leaks, a sudden drop in water pressure, sluggish drainage, unpleasant odors, and discolored water. If you notice any of these issues, it's important to have your system inspected by a professional.

You might need a backflow preventer if you have features like irrigation systems, pools, or other water elements that could contaminate your water supply. Commercial and industrial properties are required to have backflow preventers due to higher contamination risks.

A backflow preventer stops water in your main supply from reversing flow and contaminating clean water. A backwater valve is installed in your drainage system to block sewage from backing up during heavy rainfall or overflow. Both devices protect your home but serve different purposes.

The time it takes to install a backflow preventer depends on the type of system. A plumber can typically 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.
