"My project was 9 anchors to be installed in a 1955 house at the bottom of a steep hill. We have brought in 40 truckloads of dirt-well tamped and terraced the yard with limestone walls and 4 french drains. Should have done the anchors first but did not so much of the delicate landscaping had to be preserved on top of it all to complicate matters. I was nervous but the project went so beautifully and they compromised with me to maintain the character of the house. Everyone worked hard all day. Bill Bothwell was a gem and totally understood all of my concerns. He needs a raise in pay. Chris Warren who initially evaluated the project day one was great, too. He answered all of my questions even days later as I had time to think out how this was all going to effect future projects that will be happening like an addition. My yard is nice and neat and tidy-you would not know major construction happened. I am a very picky person and my landscape is happy, too. The team is great! I cannot applaud them enough! The price was super fair!"

"First, this request was NOT to repair a sump pump. It was for yard drainage. After hiring a different company. Thrasher continued to contact us which I did not appreciate."

"Where do I start?!? If I could give Jason 10 stars, I would. He was at my house an hour after I called in a panic when several drains were clogged and unusable. He was professional, friendly, and got right to work. His experience and problem-solving skills were clear right from the start. When my old pipes for one drain didn’t allow him to snake down far enough to clear the clog, he simply moved to another drain to do what needed to be done. Shortly after that, the clog(s) was cleared. When I despaired out loud while he was in the first drain that it didn’t sound promising, he simply replied, “Don’t worry, I’ll get it cleared!” I would absolutely recommend Jason to anyone and everyone who needs an experienced, honest, friendly and hard-working plumber, and will be sending my family and friends his contact information. I’m already making a list of other plumbing projects I’d like him to do for me. Seriously, the world needs more people like him."

"Mike M. giving the estimate and follow up to the actual work as great. He was really informative and gave me multiple options to work with to stay within budget and help me resolve the issue. I was super confident about getting the work done. After a week delay because the crew got stuck on a problem job. No biggie there. But when came time to do the work I found I should have gotten so much more in writing. I agreed to keep the dirt dug out because I was provided they would spread it on my side yard. Nope, I’m now sorting out how to spread this large pile and it’s ending up costing me more money and time. I also was under a different understand of where and how the sump pump would be draining than was actually the case. If I use them again I will definitely make sure whatever is agreed upon with the sales person is well documented in the contract."

French Drains FAQs, answered by experts

A small amount of diluted bleach is okay to pour down a garbage disposal. As part of your weekly garbage disposal maintenance, use 1 teaspoon of bleach with your concoction of ice cubes and lemon peels. Turn on the disposal and run the water until the blades chop up the ice cubes.

Any more bleach in your disposal can harden oils and greases in your drain, which can cause problems. Always wear gloves when working with bleach, and know that you really don’t need bleach at all—vinegar, baking soda, salt, and ice should do the trick.

It is not advisable to use drain cleaner in a washing machine. Drain cleaners contain harsh chemicals that can damage the internal components of your washer, including rubber seals, hoses, and even the drum. These chemicals can also react with any residual detergent or fabric softener, potentially leading to noxious fumes. If your washing machine is experiencing drainage issues, it's best to address the problem directly by inspecting and cleaning the lint filter, checking for clogs in the drain hose, or seeking professional repair services. Using drain cleaner in a washing machine is a risky solution that can cause more harm than good.

A plumber can get to the bottom of your smelly drain and clean it with specialized jets, hoses, and drain-safe cleaning solutions. It is also smart to call in a plumber if you suspect your drain smell is coming from a stubborn clog or even a leaky pipe.

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.

A washing machine should drain the water used during its cycle through a drainpipe and out through the house’s plumbing. This is the same plumbing that sinks and shower drains run to, and if the U-bend is installed correctly, it shouldn’t smell. The total drainage from the house is then integrated into the city sewer system or, if you’re in the country, dispersed into a septic tank.
