"Everything went well...from the time David came out to give the estimate, to working with Jennifer on getting things setup and a completed quote. To the guys and David coming out to actually install the heater. Was very impressed with Jennifer as well on how she knew our situation and worked with us to get things approved and installed. Would definitely use the guys again. The knew what they were doing and what would work for us and so far so good. Very professional!!!"

"These guys were amazing. I hired them to replace my tankless hot water heater. They took a no need to haggle approach to the estimate process, which I appreciated. The install process felt very white glove, with runners deployed left left my floors and freshly painted walls without a mark. JD was very professional and personable, taking the needed time to do the install correct the first time. They even went the extra mile and fixed an unrelated issue (was not their fault) that would have failed the city inspection. What service! These guys are my new go to plumbers "

"January 3rd, Attempted to chat online first with a representative. They were very responsive and able to answer my questions. Shortly after finishing the online chat, I received a call from their office to schedule the service. They were very accommodating of my schedule. The technicians arrived on time, were pleasant and knowledgeable, wore those plastic covers on their shoes. I needed the drains looked at in our upstairs bathroom but also asked them to take a look at the other bathroom, kitchen sink and backyard as I was noticing some stagnant water there. The Technicians were honest and up front - they diligently took care of the problem upstairs, told me everything else looked good elsewhere, showed me where grass had grown over the drainage from the back yard to the front, checked my water heater as a precaution. They were fair in their pricing and even offer a 5-year preventative maintenance plan that is extremely economical. I was absolutely happy with the service and would recommend JD Plumbing to anyone."

"The day before Thanksgiving, my sink backed up and...called Wallin Plumbing in a panic! They sent someone out within a couple of hours and Shawn showed up. He was amazing, highly professional, expedient, and very patient and kind!!! I think I saw wings on him when he left!! Seriously, in this day and age, amazing customer relations is not always the case, and the price was affordable and extremely reasonable!!! A WIN/WIN all the way around!!! Thank you Shawn, thank you Wallin!!!"

Water Heaters FAQs, answered by experts

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

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.

Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. 

If you’re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.

The lifespan of a water heater depends on its type, usage, and maintenance schedule. Traditional tank-style water heaters typically last between 8 and 12 years, though the range can be as wide as 6 to 15 years. Within this category, gas models often last 8-12 years, while electric models may last 10-15 years. In contrast, tankless water heaters have a significantly longer lifespan, often lasting up to 20 years or more. Factors like heavy usage, hard water, and sediment buildup can shorten a unit's life. To extend its lifespan, it is crucial to perform regular maintenance, such as flushing the tank annually and scheduling professional inspections. If your unit is over a decade old and shows signs of rust, leaks, strange noises, or inconsistent heating, it is likely time for a replacement.

Storage, tankless, heat pumps, and solar water heaters each suit specific space constraints, usage needs, and efficiency preferences.
