"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."

"Jacob Smyth was very cordial, honest, and he knew his profession well. His crew was polite and they did an excellent job on the new sewer line! They cleaned everything up, reconnected the chain link fence and protected the yard with plywood. I m so glad I hired them and will definitely recommend them if anyone needs them."

"Jason Dodge did a great job. Not only did he snake the drain in no time at all but he noticed the hot and cold water were reversed on my sink faucet and in 3 minutes he corrected it no charge! He couldn't have been nicer. I was only charged $100. for the whole thing. they have definitely become my go-to plumber!"

"Great drain clearing service by Jordan without all the bait and switch add-ons provided by the lower cost services. His charge included camera work before and after, with the best guarantee: no payment if he can't clear the line. He uses more powerful equipment than the cheaper services. Don't fall for the $95 service offered by others -- I tried them and they are a scam. They come out, use their lower power equipment unsuccessfully, and then try to get you to upgrade for major repairs. This guy is honest from the start and gets your line cleared in one visit."

"The pro identified the exact spot was the water leaking was coming from. He cut the part up of the pipe and replaced it with w good one, explaining every thing he was doing. He tried to make sure there was no more leaking before leaving. He further removed a clog in the drain in a sink where the flow was almost stopped."

Drain Cleaning FAQs, answered by experts

Yes, flushing a clogged toilet can make it overflow. While flushing the toilet may push enough pressure through the system to dislodge the clog, this is unlikely. Your best bet is to use a plunger and hope the suction can break up whatever is blocking the pipe. If this doesn’t work, use a plumbing auger or call a pro to help.

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.

You can unclog a double kitchen sink by plunging the side with the garbage disposal. Cover the drain hole on the other side first to avoid creating a mess. Plunge up and down until the water starts to drain. You can also pour in baking soda and vinegar to try and dissolve a clog. 

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

Yes, chemical drain cleaners contain sulfuric acid and hydrochloric acid, both of which are not only dangerous to your health but also extremely caustic. Drain cleaners will corrode your pipes and could lead to destroyed drain lines, especially if the chemicals interact with the piping for long periods. Unfortunately, this extended interaction is likely if you’re dealing with a clog, as the drain cleaner will have just as much trouble as water does moving through your plumbing system.
