"Jeremy was very responsive and informative. I had a couple of other quotes that involved various iterations of "replace the old water heater and add these other features at the same time", and we were able to talk through the suggestions and determine what was really necessary. The final quote was very competitive, the new water heater is working great, and the installation itself was fast and without any problems that they couldn't solve without me!"

"Such great service!! My water heater went out in my rental property and they were able to hop on the phone with me right away and offer me a quote. Within the next 2 hours someone was at the property - they removed the old water heater and installed a brand new one and were on there way. Cobra Rooter & Plumbing was professional and quick! Will use again in the future."

"My husband is ill and I needed help. My water heater wasn't working so I called High Speed Plumbing. Donald was wonderful ! He arrived earlier than expected and was very personable. He found the problem quickly and replaced the water heater and some electrical problems. I had smelled plastic burning so I was very concerned. I now have hot water and am not concerned about a fire hazard. I would recommend this company and will call Donald the next time I have an issue. Great experience !!"

"They replaced my tankless water heater, under sink valves with quarter turn ball valves and three toilets. The price was fair, a little high, but the quality of work and service was excellent. These plumbers know what they are doing. They were timely and had good communication."

Water Heaters FAQs, answered by experts

Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener. 

The average cost to replace a water heater is around $1,325, with a typical range of $900 to $1,800 for a standard replacement. The final price depends on the type of heater (tank vs. tankless), its size, fuel source (gas or electric), and the complexity of the installation. A simple one-to-one replacement will be on the lower end of the cost spectrum. However, if you are switching from one type of heater or energy source to another, you can expect labor costs to be significantly higher due to the extra work involved. It's also worth considering that while gas and electric heaters may have similar upfront costs, their long-term operating costs can differ based on local utility prices.

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

A leaking water heater could potentially last for a few weeks or months before you need to repair it. However, it's not advisable to wait too long. Once your water heater starts leaking, it's likely that the underlying cause of the leak is getting worse as time goes on. Without immediate repair, your water heater could fail. Instead of using a leaky water heater, you should turn it off and call a pro to fix it.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.
