"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

Gas water heaters last between eight and 12 years on average. You can help them reach their maximum lifespan with regular cleanings, maintenance, and professional checkups, though don’t hesitate to swing for a full replacement if the total cost of repairs is greater than that of purchasing and installing a new unit. 

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.
