Water Heater Service in the Bay Area

At least once per year, your water heater should be serviced. The calcium in Bay Area water leaves sediment in the bottom of your filter, creating insulation between the burner and the water. Over time, this lowers the efficiency of your unit. That may mean your water doesn’t get as hot. It could also cause leaks.

Water is a solvent, which means it attacks metal. Inside your water heater is an essential piece called the “sacrificial anode.” This long metal rod is made up of magnesium or aluminum, and it attracts other minerals. Over time, your water will corrode the sacrificial anode. If it isn’t replaced, your water will begin attacking your tank.

When we service your water heater, we will flush the system. This removes that sediment and prevents buildup. It keeps your water heater running as intended and keeps the water in your home reliably hot. Regular water heater maintenance can extend the life of your water heater for the full 10 to 15 years. Through our membership plan, we will do a complete check of your household plumbing once per year.

Bay Water Plumbing Water Heater Reviews

“My water heater stopped working. I called several places and I was offered appointments two to three days. When I called Bay Water Plumbing, they came within 30 minutes. Ordered the parts which were recalled from the factory. After a few days the parts arrived, they sent their excellent technician and my heater was working within an hour. Great job. Thank you!”

– Parween E.

“Our water heater's pilot light kept going out, resulting in multiple cold shower experiences, so we chose Bay Water Plumbing to fix it, based on their high Yelp rating. We ultimately decided to replace the water heater instead of repairing it, since it was an older unit anyways. Alvaro gave me a fair replacement offer and was able to install the new unit later on the same day. It's been working great for over a month now and no problems. It's more common to get burned by dishonest plumbers than to find a plumber with good moral integrity. Alvaro and Francisco at Bay Water Plumbing have proven themselves to be a great choice when seeking a plumber you can trust and I'm a happy customer. Thanks guys!”

– David S.

“Alvaro is probably the best plumber I have met. Always very professional, organized, on time and demonstrates great knowledge and expertise in what he does. Excellent skills in plumbing related jobs. And on top of all that, he charges a very fair price. We installed water softener system, filtration system and did water heater annual cleaning with Alvaro. Amazing person to work with. Thank you and look forward to working with you again.”

– Joe Z.

Water Heater FAQs

At Bay Water Plumbing, we do a lot of warranty work for our customers. For most brands, there is a six-year warranty for replacements—up to one year covering labor. Typical issues we see include the control valve and burner replacement. If you have an issue that should be covered by warranty, call the manufacturer first. And when you’re ready to get the work done, call us.

Water heaters improve energy efficiency, meaning they save you money long-term and are better for the environment. If you’re considering upgrading to a tankless water heater, Bay Water Plumbing can help. We also manage installations, as well as yearly servicing and tankless water heater repairs.

Water heater placement is very important. For example, many water heaters have vapor sensors that cause them to shut off if they detect flammable vapors. Without the right ventilation, water heaters with vapor sensors can misfire. If Bay Water Plumbing installs your water heater, we’ll help you determine the best place to put it.

With all water heaters (standard or tankless), when you turn off your hot water, the water stays in your pipes. So, the next time you turn on your hot water, it must flow through the pipes first, before the newly heated water reaches the faucet.
