"Beau and Ryan answered all of my questions and were very friendly. They showed up within the given time frame and removed the old tank and installed the new tank quickly and efficiently. The cost did go up due to replacing the water inlet and outlet lines and the gas inlet line. New tank, might as well have new lines. 1st Response should mention in their coupon that water/gas lines will add to the cost since Beau explained that the water lines almost always have to be replaced and the new gas line is required to maintain their lifetime warranty. Code required the installation of a condensation trap which at $125 I thought was a little over priced. Overall a good experience and I would probably use them again."

"We hired them to install a 40 foot french drain. Eric was very knowledgeable and professional, not to mention a very nice person and good listener. He was punctual and he and his crew were extemely hard workers. The job functions as promised, looks great and they were very conscientious about how they left the work area neat and clean. I wish I could hire them for other projects."

"Ron was very courteous and professional. He was very thorough and after unclogging my drain came back with three estimates for fixes. He tried to put a camera down my cleanout but couldn't get it open after trying for a while - he was trying to give me an estimate on how much longer I had left in my old cast iron pipes."

"French drain installation along a retaining wall (75 yards). Thomas who handled the sales end of things was friendly and responsive. The crew showed up on time. They were hard working and receptive of customer feedback. They first removed the ivy that was obstructing the work area and then completed the trench on day 1 which uncovered some of the unwelcome water sources. A legacy footing drain was plumbed directly into the main french drain pipe. Perpherated pipe was dropped in on Day 2 followed by river rock, catch basins, and 3 ft dry well installation. Cleanup was done thoroughly. I would hire them again in a heartbeat."

Drain Pipe Installation questions, answered by experts

There are a few reasons your snake won’t go down the floor drain. One common reason is a large obstruction in the drain that is causing a blockage. You can remove any debris you see in the drain before trying to snake it. In addition, the snake might not be long enough to reach the clog, or it might be the wrong diameter. 

That pungent rotten egg smell coming from your drain is likely the buildup of biofilm—hair, skin, and soap scum that turns into a black sticky mess. In this case, pouring down near-boiling water, baking soda, and white vinegar will remove the smell. Keep in mind that a rotten egg smell is occasionally a sign of larger sewage line clogs and other related issues.

To unclog the drain pipe, remove the machine's drain hose from the pipe or sink drain, being careful to contain any water in it. Next, use a plunger for sink drains or a plumbing snake for a wall drain. Test the repair by pouring a small amount of water into the pipe before trying it with a laundry load.

Regrading your yard can often fix drainage problems. You can also try aerating the lawn to encourage better drainage or install a new drainage system to prevent water from pooling in certain areas.

Some experts estimate that descaling your cast iron pipes can extend their lifetime by upwards of 50 years, although there’s not a lot of research to prove it. But we do know that without proper maintenance, cast iron pipes can quickly rust—leading to more expensive issues like burst pipes or main line clogs.
