"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."

"Fast response took care of replacing my 20+ year old 120 gallon solar water heater. They ordered the water heater on a Monday afternoon had it installed by Thursday morning. It was not easy finding someone just to swap out a water heater that's for solar. Most plumbers shake in their boots when I mention solar, especially only a water heater swap-out."

"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."

"I was just getting estimates over the phone on several different projects. I think I spoke to Shawn. He was kind enough to take a few minutes to explain tankless water heaters to me as well as a ballpark cost. Which was exactly what I asked for and all I needed to plan my proactive project list/budget. Thanks"

"High on my priority was an energy efficient water heater--not in comparison to my old water heater but in comparison to water heaters now made. After listening to my wishes the plumber recommended one. Unfortunately after it was installed, the yellow energy efficient sticker told me otherwise. My recommendation is that when you deal with Tucker Hill as with any plumber you haven't dealt with before, that you fact check."

Water Heaters FAQs, answered by experts

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.

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it’s actually a silent threat to plumbing.

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.

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.
