Here are the possible causes of low water pressure:

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.

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.

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!

Reasons Your Home Has Low Water Pressure

•    Corroded pipes

Corrosion and mineral build-up narrow the inside of the pipe, causing low water pressure. This problem is common with galvanized steel pipes. Deposits may build up inside pipes due to years of exposure to water. If your plumbing pipes have become corroded, the best way to fix the problem is to replace them with copper or pex plumbing pipes. But before you consider replacing your existing pipes, be sure to consult with a professional New Jersey plumber. 

•    Leaks

Major leaks in your home’s plumbing system can cause low water pressure throughout the home. If the leak is big enough, it can misdirect your water supply to a point where you’re not getting full flow. If you notice signs like wet basement floors and high energy bills and at the same time you’re experiencing low water pressure, there are good chances that the problem could be caused by a major water leak. 

•    Faulty fixtures

If your water pressure is low in one or a few fixtures, then probably your fixtures might be the problem. Issues like a clogged aerator, faulty pressure regulator, and sticky valves could be the cause of low water pressure. The fixtures may get clogged over time due to build-up; hence disrupting the normal flow.

•    Poor plumbing

Bad plumbing jobs are a major cause of low water pressure in many homes. Your plumber may have used the wrong pipes in terms of size, and the joints may have been done badly, so they end up creating flow restrictions. If your water pressure has dropped and you recently made additions to your plumbing system, your plumber may have altered the plumbing lines causing flow restrictions.    

•    Inadequate water supply line 

Sometimes, your low water pressure problem may have nothing to do with your plumbing lines or fixtures. Your main water supplier may be experiencing an issue. For instance, they could be doing water hydrant testing, which can cause temporary pressure loss.  

•    The water meter valve is partially closed 

If your water meter valve is partially closed, you could experience low water pressure. This commonly happens after you’ve done renovations in your home or altered your plumbing lines. 
There you have it. These are the possible causes of low water pressure in your home. Whenever you experience low water pressure in your home, it’s a good idea to call an experienced plumber in New Jersey to help you out.
