"Isaiah came out on time and did a complete review of my system. He gave me several options to choose from. I selected the one that worked the best for my needs. He made a quick run to the supply house and returned to finish the work and was done with in 2 hours. I am very happy with the work he did and the water heater we have. It works flawlessly. I would recommend him & Topshell to anyone."

"Ken was the first plumber that gave us a reasonable price to install a shower tower. We didn't want to pay for a maintenance membership or to pay for someone's vacation house, we just wanted a simple plumbing matter taken care of. Ken was exceptional. He arrived on time, was very knowledgeable and explained every step of the procedure. We will definitely call Ken in the future for our plumbing needs. He also noticed that our pressure relief tank, for the hot water heater, was hanging low and had water inside it. It needed to be replaced and he was able to do that job too. Highly recommend!"

"We needed to check our water heater for leaks prior to closing the sale of our house.Joe Lay were out installing a new water heater and expansion tank the next day. The technician explained how all the components were supposed to work before checking everything so we both knew we needed a new tank as well. Outstanding, professional company. Billy was very respectful, knowledgeable and professional the entire time in our home. We would highly recommend Joe Lay and Sons for any plumbing needs."

Water Heaters FAQs, answered by experts

Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. 

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.

Often, the first issue you might encounter is a lack or loss of power—this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion.

If you want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.

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.
