"Drain was initially cleared using a drain augur, but inspection via camera revealed that additional cleaning was needed. A followup visit happened about a week later to perform a hydro-jet flush and the video inspected now showed a very clean drain pipe. The technician was very professional and explained the steps he was following and what he observed. I would recommend this company for this kind of drain service."

"Very professional. Alex and his assistant installed a new water after explaining the features of the different models that fit what I was looking for. They were able to "think outside of the box" to solve a problem, explaining to me each step. They included principles of chemistry in drain water and contact with specific water shield materials in their decision-making. They were friendly, personal, and considerate. And clean! Highly recommend."

Small jobs welcome

"Removed hot water heater, added tankless heater. unclogged slow drains. Very professional, 3 guys showed up and made quick work of the projects. Walked us through what they were doing, in a professional, easy to understand manner. Gave us final directions on how to use the new tankless heater. Also, informed us on what to look for if our 70 year old pipes start having issues. They did not push us to spend a ton of money to re-pipe the house now. We will be contacting them for any future projects. Great job, Rob, Curtis, and Brandon!!"

French Drains FAQs, answered by experts

French drains may fail when they become clogged with soil granules that slip through the pores of the landscaping fabric and through the holes in the pipe. 

Over time, this debris can build up inside the pipe and prevent water flow. To prevent this failure from happening, regularly flush out your French drain and keep debris away from the inlet grate.

As a preventative measure, hydro jetting should be done every one to two years. However, the best practice is to hydro jet your sewer line once per year. The ideal frequency depends on several factors, including the age and condition of your pipes, how prone they are to clogging, how often the sewer line is used, and the type of waste disposed of in the system. If you frequently experience clogs or are unsure, it's best to ask a licensed plumber for a recommendation specific to your plumbing system.

It is okay to use a drain auger on a toilet, just make sure you are using the correct tip size. The auger is a plumbing snake with a protective sleeve to protect the porcelain toilet bowl from getting scratched. Using too large of an auger can cause the snake to loop back and damage the inside of the drain and plumbing.

Drain clearing removes debris and clogs from drain pipes enough to allow water to drain properly. On the other hand, drain cleaning removes all of the material from the pipe so that water flows unrestricted, which is a longer-term solution. Your plumbing pro will be able to recommend the right service depending on the clog size, frequency of issues, and surrounding pipework.

Professional plumbers use many high-grade chemicals to unclog drains. Many use hydrochloric acid, known as muriatic acid, when it comes to extreme blockages.
