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.

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 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.

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!!

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!

Addressing a Leaking Water Heater: A Guide to Quick Action and Solutions

Mr. Rooter Plumbing is a reputable plumbing company offering reliable and affordable water heater services. One of the common issues we fix is leaking water heaters. We understand what causes water heaters to leak and how to effectively address the problem. Today, we’ll look at how to address various causes of water heater leaks.

Corrosion

Over time, water heaters can develop rust inside the tank due to prolonged exposure to water and minerals. Corrosion weakens the tank’s structure and leads to leaks that often start small but can quickly worsen.

Solution

If corrosion is localized, replacing the affected parts may work temporarily. However, extensive rust typically means it’s time to replace the entire water heater to prevent sudden failure. Consider installing a water softener to reduce the impact of hard water on your plumbing system.

Sediment Buildup

Minerals in hard water can settle at the bottom of the tank and form a layer of sediment. This buildup can cause cracks in the tank or lead to overheating.

Solution

Flushing the tank regularly helps remove sediment and extends the unit’s lifespan. For severe buildup, a professional plumber may recommend descaling treatments or replacing the heater if damage is extensive.

Temperature and Pressure Relief Valve (TPRV) Failure

A malfunctioning temperature and pressure relief (T&P) valve can lead to leaks if it’s stuck, damaged, or releasing excess pressure. Over time, mineral buildup or wear and tear may prevent it from sealing properly, causing water to drip around the valve or overflow pipe.

Solution

Begin by tuing off the water heater and draining some water to reduce pressure. Carefully remove the faulty valve and install a new one and ensure a tight seal. If excessive pressure persists, have a professional plumber inspect the system to address any underlying pressure or temperature regulation issues.

Faulty or Loose Connections

Leaks can occur at the connections where the water supply lines enter and exit the tank, as well as at the drain valve. This problem is more common in older water heaters.

Solution

The solution to this problem is simple—tighten the connections to resolve the issue. If the problem occurs frequently, it may be time to replace the water heater.

Aging Components

As water heaters age, seals, gaskets, and other components wear out. This makes leaks and breakdowns more likely to occur. Older units often experience multiple issues and need to be replaced to save money in the long run. The average lifespan of a storage tank water heater is 8-12 years, while a tankless unit can last up to 20 years.

Solution

Routine maintenance can extend a water heater’s lifespan, but older units may require frequent repairs. If parts continue to fail, replacing the entire water heater is often the most cost-effective solution. Contact Mr. Rooter Plumbing for water heater replacement.
