"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"

Water Heaters questions, answered by experts

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.

Unusual noises, lack of hot water supply, efficiency loss, and visible leaks are signs of necessary replacement beyond mere repair.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

Electric water heaters typically last 10 to 20 years, though proper maintenance can extend their lifespan. If your unit is over a decade old and showing signs of inefficiency—such as higher energy bills, frequent repairs, or leaks—replacement is a smart investment. Tankless models last over 20 years, which can make them a longer-lasting alternative to traditional tank water heaters.
