"It went very well. The problem was fixed completely. I'm very satisfied. I thought the problem was simply a defective pressure relief valve. Not the case - the problem was a water logged expansion tank. Joe drained the system, installed a new expansion tank, a new automatic water feed with back flow prevention, a new 30 psi pressure relief valve, and a new automatic air vent. All the replaced components were old, so it made good sense to me to replace them. Joe even installed shut-off valves on the water feed and expansion tank line so that if new the expansion tank ever becomes defective, it can be replaced without having to drain the system. When everything was installed, Joe refilled and purged the system and thoroughly tested it before leaving. I am completely satisfied with the worked performed. Excellent work and good value."

"Melinda,a very pleasant customer service person,called me promptly this morning 15 or 20 minutes after my post of our need. A tech could come today to unclog our drain. Very pleasant tech came to do the job, Steve. I haven't seen much about pricing for this service.While I was looking for a plumber this morning I did see some ads By other companies to unclog a drain for $250. This company charged $225 for the first hour and was prepared to use a camera if necessary within that price. Very good and briefexperience overall."

French Drains FAQs, answered by experts

Keep your egress window from flooding by ensuring that the drainage system in the window well is clear and in good working condition. Inspect the window well every few months to remove any blockages and test the drainage system. It’s better to discover potential problems before your window well fills with water during heavy rain.

Yes, many services include camera inspections to identify the cause of the blockage. Confirm with your provider.

While there is no specific “best” method to clear hair out of a drain, several options work well. Using a combination of baking soda and vinegar to dissolve the hair clog is a great and easy way to help clear the drain. Drain snakes are also effective for more severe clog buildups. 

Yes, you can use hydrogen peroxide to unclog a drain. Instead of using a baking soda and vinegar solution, you can use baking soda with hydrogen peroxide. The process to unclog a drain is the same as with vinegar, but use 1 cup of hydrogen peroxide instead.

If you have a sink stopper, it can feel more challenging to clean the drain without removing it, but here are a few simple steps:

  • Pour ½ cup baking soda into the drain using a funnel

  • Pour 1 ½ cups vinegar into the drain

  • Close the sink stopper for 15–20 minutes

  • Open the drain

  • Pour 2 cups of boiling water down the drain (be cautious as boiling water can damage some types of pipes)

If the drain isn’t unclogged, repeat the process.
