Our Customers Reviews

Chahib Chakrome

Summit, NJ

The service provided was great, nothing to say about the work of the plumber. 5 stars to him. But the company charges felt way too much for the work. We would have liked to have the same plumber take care of other things in the house, but every time he check how much extra the company will charge for the job, the price just got too much. The plumber did an amazing job he selected a beautiful faucet to replace our old one. He did his best. But the company prices have no room for negotiation.

New Brunswick, NJ

We got very quick service, I think the plumber actually arrived in less than an hour! After reviewing what was happening, he gave us our options and performed the option we selected. This happened in the late afternoon or early evening. It was already dark and there was a lot of snow on the ground.

Steve Smith

Mountainside, NJ

I needed immediate, same day service in the early evening at my home. I went to the internet and looked up plumbing services that offered "24-hour, 7-day a week" availability. The first 3 places I called said that they could not get to me until the following day. Then I called Mr. Rooter. They were courteous and promptly got a technician to my house within an hour and a half. The technician, Lucas Kaufmann, was exceptional. The job was not easy, but he figured the problem out and got me all fixed up within an hour's time. Moving forward, I…

Cranford, NJ

Despite what was quite obviously a busy day (day after Thanksgiving at 10pm) TJ came out and did not leave until the job was done! There were several setbacks, which at the late hour might have prompted him to leave- but he chose to stay and continue until the job was complete! I only have one bathroom so I was really hoping he could make it work, and he really did a wonderful job! So thankful for all of his help! I highly recommend TJ!

Union, NJ

This is my second time using Mr. Rooter and I have to say they are an excellent company of experienced professionals! The service techs were courteous, experienced and actually spent time trying to figure out the issue before proposing the solution. They were also patient and answered all my questions without rushing the work. I will be using them again.

Christie Murphy

Montgomery, NJ

TJ was amazing! 10/10 recommend this company. We were in an emergency state of panic with a burst pipe in the middle of a bad snowstorm. TJ came with knowledge, professionalism, kindness, and found the root of the problem within five minutes of being here. We will be using him again in the spring to fix an outdoor issue he found!

Alan Abraham

Clark, NJ

The technicians were friendly, professional and knowledgeable. The price was too high I believe, but the technicians had no control over that. The technicians took their time and did a great job. I would use them again and also recommend them.

Amy Swart

Berkeley Heights, NJ

Excellent service! Charles and Nicholas of Mr. Rooter arrived to my scheduled service a few minutes early, wore sanitary shoe coverings, and were extremely professional. They found the source of my leak quickly and fixed the issue. While they here, I requested an additional hydraulic heating inspection which they accommodated. They were very knowledgeable and provided helpful tips. I highly recommend this team and I will definitely call them for all future plumbing needs!!

JACKY Coppola

Thank you for employing such an amazing man. Plus today there is water running in the house. Thank you TJ and thank you Mr. Rooney plumbing for employing a man with helpful hints!!!!!

  • Check the Main Water Shutoff Valve

Are you experiencing low water pressure throughout your home? The first thing you should do is check if your water shutoff valve is fully open. This valve may be half-shut after undertaking plumbing repairs or renovations in your home. The main water shutoff valve is commonly found near the water meter or in the basement. It is important that you know the location of this valve and test it regularly to make sure it is not stuck. Knowing its location can come in handy when you encounter a plumbing emergency such as a burst pipe. If the valve is not in good working order, call a skilled local plumber for help.

  • Inspect Your Pipes

Another common cause of low water pressure is clogged water supply lines. Your pipes can become clogged due to mineral buildup, pipe damage, and tree root intrusion. Even a small tree root can interfere with your water pressure and bring your household routine to a grinding halt. If you have hard water in your home, the minerals in the water will accumulate on the pipe walls and eventually reduce the diameter. It is advisable to have a professional plumbing service install a water softener. In addition, it is important to inspect your pipes regularly to identify potential blockages and have them fixed before they compromise your water pressure.

  • Check the Water Pressure Regulator

A water pressure regulator is installed on the incoming water supply line to keep water pressure in check. The acceptable water pressure for a home’s plumbing infrastructure is between 40 and 80 pounds per square inch. This control valve can fail as a result of normal use, mechanical problems, and exteal factors such as incorrect installation. When a water pressure regulator fails, the pressure may drop to a trickle or go above the acceptable limit. If your water pressure regulator has malfunctioned, call a professional plumbing service for an inspection.

  • Clean Faucet Aerators

Faucet aerators regulate the amount of water exiting the faucet by mixing air with the flowing water. These devices are installed at the end of a faucet to create a more consistent stream of water. When they become clogged with mineral buildup and sediment, the water pressure in the affected faucets can drop below the acceptable level. Thankfully, cleaning clogged faucet aerators is a simple task that doesn’t require any professional expertise or special tools. Simply take the aerator apart and soak the parts in white vinegar for 5 minutes. Scrub the parts with a brush and rinse them under water. If you still experience the same problem after cleaning your faucet aerator, it may be time to call a professional plumber to replace them.
