Our Customers Reviews

Larry R.

Howell Township, NJ

It was a late Saturday night. We had a super stubborn clog in some old galvanized pipes. Mr. Rooter send out Phil. Phil was great! He found the problem pretty quick. With determination and professionalism he final got it cleared out. I would recommend Mr. Rooter and Phil to anyone! He even cleaned up. We are so happy we choose Mr. Rooter!

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.

Debbie Dimitrion

Colts Neck, NJ

I just wanted to say James did a great job at my house. Excellent service, professional and very nice. Thank you so much for helping me with my plumbing problem. Did wonderful job.

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.

LarJ MarJ

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!

Why Is My Dishwasher Not Draining

Faulty Hose

The drain hose is an important component since it connects your dishwasher and sink together. Over time a lot of food, oil, grease and other debris can make its way into the hose via your kitchen sink. If left in place, the materials can harden and block the flow of water. Clear out the grime or change out your hose if it has become damaged in any way.  

A Clogged Filter 

Filters can also become clogged. After all, their intended purpose is to catch leftover food from your pots and plates. However, if they aren’t routinely cleaned, the small mesh filter or large basket shaped filter can become caked with residue. Be sure to clean the filters at least once per month with gentle soap and warm water. This should keep blockages to a minimum. 

Existing Plumbing Issues 

If you have already ruled out the possibility of a clogged filter or hose, then the likely cause is underlying problems with your pipes. Deep sewer line clogs, hidden pipe damage and root infiltration are all common issues that can block wastewater. If you are also having trouble with slow draining sinks and tubs or overflowing toilets, then this is probably the reason. A thorough professional plumbing inspection can pinpoint the exact source of the issue, so that it can be taken care of swiftly. A buildup of grime can often be resolved with a professional drain cleaning and hydro jetting service. Minor root invasion and leaks can usually be fixed with non-invasive trenchless pipe repairs. Severely neglected or damaged sewer lines may require a conventional replacement. A certified plumber will have the training and tools needed to inspect, diagnose and repair your pipes so you can enjoy a safe and efficient plumbing system again.
