"Saved by Ehrhardt Brothers Quality Plumbing (a.k.a ColumbiaPlumber)! (West of Baltimore) Our gas water-heater failed! It’s 30° outside! (Mar 2026). It was leaking, so we shut off the gas, the pilot, and the water inlet, to lessen damage if it burst. Ehrhardt offered a price based on our descriptions and photos, of course with caveats for anything unexpected. A water-heater costs a pretty-penny, but less than we expected. A fair price. They came the next morning, and had the water heater replaced in 90min. Impressive. But the manufacturer sent a unit with a bad pilot! Ehrhardt returned immediately and in 30min, they figured it out. They had a replacement part over-nighted. The next morning, in 30min, done. Hot water. AAAAAHHH :-) The problem was the manufacturer’s fault, and Ehrhardt handled it flawlessly: Excellent communication by Ehrhardt, priority attention to our problem, no excuses, just fast resolution. Great service staff. Perfect!"

"Well let me start by saying I called several water heater companies to inquire about an estimate for my hot water heater that was not getting real hot. He was the ONLY repair person to come out that gave me the feeling he was trying to fix my hot water heater and not trying to sale me a new hot water. I never had a hot water heater water heater issue before therefore i was not familar with pontential problems. Everbody tried to get me to buy something called elements without actually trying to fix my heater. Wallace plumbing was able to identify some pressure thing or something with the thermostat that he fixed and saved me pontially thousands of dollars that other companies tried to sales pitch me. I then called Wallace plumbing because my toliet kept running and Wallace came out and fixed my toliet in minutes and his prices are very affordable. I will be using Wallace plumbing for any future needs and I recommend them!"

"Along with installing a new water heater, plumber also installed new upstairs showerhead, and checked faucet in kitchen and 1st floor showerhead for buildup. Plumber was friendly and willing to answer any questions/concerns that I had. Will definitely keep in mind for future plumbing issues."

"Finally! When friends ask if I know of a reliable, honest, plumber at reasonable cost, I have found one to give as a referral in Water Field, LLC. Tes arrived on-time and assessed what was needed to correct my pipe leak problem in short order. While waiting for his repair work on the leaky pipe to cool, Tes offered to check all the other fixtures in my home to ensure everything was in order. When I mentioned one of my toilets was not properly anchored to the floor, an annoyance to me for quite some time, he fixed it at minimal cost. Water Field, LLC is now officially my go-to plumber.

"Andrew and his team were great from start to finish. He was able to match pricing, which initially was a concern, and the speed and quality of installation has been more than worth it... The installed system has been working flawlessly especially as the temperatures started dropping. I will definitely use them again, and at other locations. Andrew is very knowledgeable, easy to talk with and ask questions, and a perfectionist at what he does.. this quality-oriented approach really shines through and makes Amazing Heating & Air stand out high above the competition."

Water Heaters questions, answered by experts

Yes, most municipalities have codes that require water heaters to have pans. A pan is necessary when a water heater or hot water storage tank is installed in an area where water leakage could cause damage, such as an attic, second floor, or finished basement. Tankless water heaters are not required to have a pan since there is no storage tank.

The average cost to install a new water heater is approximately $1,300, with a typical price range between $880 and $1,800. The final cost depends on several factors, including the type and size of the unit, its location and accessibility, and the amount of labor required. For example, installing a unit in a tight space like a crawl space can increase labor costs. The type of water heater significantly impacts the price: while a conventional gas heater might cost less than $1,000, tankless models can cost around $2,600 to install (and up to $3,500), and solar heaters can cost upwards of $3,700. Other factors that can affect the total price include the fuel type, vent system requirements, permits, and whether any additional plumbing work or repairs from previous water heater damage are needed.

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.
