"Quick! Contacted me within minutes of Home Advisors inquiry, showed up and did outstanding work within 3 hrs of initial contact - even though it was a no-rush job. Got my water heater set up in a jiffy; good price and I am glad I called them. Would highly recommend."

"Hunter and Sean are the real deal! My water heater crapped out suddenly on New Year’s Eve. I went to Angi and filled out the info and less than 10 minutes later, Hunter calls me! Told me he’d be out the next day….new year’s day!! Showed up when he said he would, diagnosed the issue quoted me a price and said he’d be there “tomorrow morning”. Showed up, just like he said he would for the price he quoted. Everything went well, and I wholly recommend Foothills Plumbing."

"Ken replaced our water heater. Seems to know his stuff, and it's working fine. He had to take a trip out to get a missing part that he thought he had, but he adapted on the fly and still got the job done the same day only taking about an hour longer than expected. Friendly and capable."

"Both of the owners were polite and easy to work with. They showed up on time and did quality work to replace very poor work done by another plumber. They weren't the cheapest but you get what you pay for. I know after replacing three hot water heaters in 16 years."

"We had a situation the evening before, with a leak in an upstairs bathroom tub that sent water down into the master bathroom. The remediation company came that next morning to dry things out, but they did not have the skillset to work on the actual plumbing problem. I reached out to Angi's list, put in what I was looking for and selected Three Sons Plumbing. When I hit the go button on Angi's list, I received a call within a few minutes from Brandon the owner. He came over immediately and assessed the problem. He and his helper worked with the remediation team and had the plumbing issue knocked out in less that 45 minutes. Great service. Very reasonable rate. Overall job well done. I would recommend Three Sons anytime. Sean"

I am very happy with the service that I have received. I was referred to them by a coworker and they are honest with what they do and will do anything to help you out! i would highly recommend All About Plumbing to everyone i know, even strangers! Thank you Steve and your crew for all that you have done for me and my family. "

Water Heaters FAQs, answered by experts

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.

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. 

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.

Unless you have previous plumbing experience or extensive experience with water heaters, you should avoid replacing your electric water heater yourself. This process involves disconnecting wiring and parts from the old water heater and reinstalling them onto the new one, among other difficult tasks. This job is best left to the pros to make sure that everything is connected correctly to avoid serious leaks or malfunctions.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
