"⭐⭐⭐⭐⭐ Water Heater SOS was a lifesaver! When our water heater broke down, they responded quickly, diagnosed the issue, and had it fixed the same day. The technician was professional, knowledgeable, and took the time to explain everything clearly. Pricing was fair, and the service was top-notch. I highly recommend Water Heater SOS for anyone needing fast, reliable water heater repairs!"

"Mike responded to my request immediately, set up an appointment to look at my job and give an estimate right away, and then completed the work in 4 days. Within 8 days of my call my new water heater was installed. The contract was clearly set out, and the work was very professionally completed exactly as per the bid. Mike was very friendly and easy to work with. He left the work area clean when he left. I highly recommend Mike and Jax Mechanical."

"Your guys CJ & Andrew were awesome! They did such a nice clean looking job! Super professional and very informative. They walked me through setting up the app for the whole house water shut off valve they installed and now I get a reduced rate on my homeowners insurance. They also found that my water pressure reducing valve had failed and replaced that at the same time. Couldn’t be more happy with the job they did."

"Anthony arrived on time and went straight to work. He worked steadily and when completed explained that the heater is in good shape with nothing wrong. He did not have the intake filter with him so he offered to come back and install it, this was not part of the original deal. He showed up this morning and installed the filter, cleaned the vent and cover. Excellent customer service.

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.

With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

Water Heaters questions, 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.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

Electric water heaters do not need an attached vent, but the location of the water heater should allow for roughly 12 inches of clearance around it. This allows cool air to flow around the appliance and allows repair technicians to work on its components safely. The exact amount of clearance space required depends on your local building codes.

Your water heater's age can affect your homeowners' insurance policy. Many policies will ask how old the heater is when you first apply for a policy—and they may make you replace a model that's over 10 years old. 

Even if your policy permits you to have an older heater, it may significantly reduce the amount of protection available. If an older water heater suddenly leaks and causes damage to parts of your home, your policy may not cover it.
