Rose Bernard

Red Bank, NJ

We had a plumbing emergency and found Mr. Rooter while frantically searching for a 24-hour plumber. We feel like we hit a gold mine. Not only did we get a timely response. Everyone at Mr. Rooter was friendly, professional, competent and went above and beyond. Our plumber, Phil, was extremely helpful and gave us tips we could use moving firwars. Not to mention, the cost was extremely reasonable.

Joseph Chis

Hillsborough, NJ

Had sewer water backup in toilet and tub. Received callback as promised and arrived early. The tech determined we needed the main line to be cleared. He quickly located the opening and had us cleared in minutes. Very happy with the service. I was not prepared for the fee but it was an emergency.

Christopher Cox

Little Silver Township

Plumber, Phil, came out on short notice on a Saturday night and fixed our issue quickly, professionally and courteously. I contacted a different, well known plumbing company right before Mr. Rooter. The receptionist was rude and they didn’t call me back to say they couldn’t make it until after Phil left! The Mr. Rooter receptionist was very nice and they called me back quickly. I’m glad they did.

Rachel Turunen

Jackson Township

I was very happy that I went with Mr. Rooter’s. The service was very quick and up front. Jessie James was very helpful answering my questions and replacing my hot water heater. He was pleasurable to do business with. If another problem arises in my home, I will be using this company again.

William Holden

Brick Township, NJ

A thorough, professional, pleasant experience. I had a back-up in the 50 year-old pipes of my new home. I called Mr. Rooter to have them locate the blockage, snake the line, and then use their video snake to get a visual of the integrity of the pipes. I’m glad that I called and will use them again for future needs.

Oakhurst, NJ

You get what you pay for. Edwin Robles of Central NJ educated me as a 1st time homebuyer on why and what he was repairing, prevention, PROMPT,(on a sunday at that!) clean, knowledgeable, super professional but DOWN TO EARTH and at a REASONABLE PRICE! Sewer pipes unclogged and main water line fixed. I was no longer crying once job was thoroughly executed. After all $#@* $tinks but somebody has to do it and I HIGHLY recommend him and this company for a job well done. THANK YOU VERY MUCH!!

Margie Rafferty-Criscione

Ocean Township

Absolutely lovely office staff! I always knew when the repair person was coming. Lorenzo our repair guy was awesome, I really don't think there is anything he can't do. He looks young, but don't let that fool you! So happy all the repairs are behind us. We really just did a one-stop shopping and decided to have everything we've put off fixed because it was such a tremendous experience!

What to Do About Air Lock in Waste Pipe?

What is an airlock? This is the first question you must ask yourself before attempting any DIY solutions. An airlock is a trapped pocket of air in your drain lines, usually caused by a clogged vent pipe. Failure to address the problem early can restrict water flow and cause other plumbing issues.

Slow Drains

If a drain in your home is not draining as expected, it could be caused by an airlock in your plumbing system. Keep an eye out for bubbling or gurgling in the toilet, which is usually followed by slow drains. You must schedule an inspection with a professional plumber if you see any of these signs in your home.

Incomplete Toilet Flush Cycle

A toilet that doesn’t complete a flush cycle, but water still swirls around the bowl as it goes down slowly, is a sign of an air lock problem. It is also accompanied by some gurgling in the shower, tub, and sink, prompting pipe repair before the situation becomes more pronounced.

Both scenarios can be caused by a blocked air vent, especially during the cold season when there’s a constant flow of air in and out of the roof air vent. The air freezes at the opening and builds up over time until it seals the duct completely.

Air Lock in Sump Pump

An airlock in your sump pump can cause significant damage that is costly to repair. The purpose of a sump pump is to move excess water from the basement floor and foundation. If this function is prevented, you risk compromising the structural integrity of your building and the subsequent water damage.

While an airlock problem is not usually a cause for conce, failure to address the problem can have severe repercussions on your plumbing. However, if a simple DIY solution doesn’t solve the problem, a professional pipe repair service should inspect to detect and rectify the situation. Contact us at Mr. Rooter Plumbing and schedule an appointment with an experienced and well-equipped plumber. We guarantee quality plumbing services at competitive market rates.
