Water heater maintenance & flushing

Hard water shortens the life of water heaters in Northeast Florida. A yearly flush and inspection helps your unit last longer, run cheaper and avoid surprise failures.

Small maintenance, big savings

Every time water is heated, minerals settle at the bottom of the tank. Over time that sediment insulates the burner or elements, so the heater works harder, gets noisy and wears out faster. Tankless units build scale inside the heat exchanger instead.

A maintenance visit removes that buildup and checks the parts that keep your heater safe, especially the temperature & pressure relief valve and the anode rod that protects the tank from rusting.

What a maintenance visit includes

Tank flush

We drain and flush sediment from the tank to restore efficiency and quiet operation.

Anode rod check

The anode rod sacrifices itself so the tank doesn’t rust. We inspect it and replace it if needed.

Safety inspection

We check the T&P relief valve, venting, gas connections, expansion tank and drain pan.

Tankless descaling

We circulate a descaling solution through the heat exchanger and clean the inlet filter.

Due for a flush?

Book a maintenance visit and keep your water heater running longer.

Water Heater Maintenance FAQ

How often should I flush my water heater?

Once a year is a good rule in Northeast Florida. With very hard water, or if you hear rumbling, more often helps.

Can I flush it myself?

You can drain a few gallons from the drain valve to clear loose sediment. Old valves sometimes leak afterward, so a pro flush with an inspection is safer for older units.

What does an anode rod do?

It’s a metal rod that corrodes instead of your tank. Once it’s used up, the tank starts to rust from the inside.

Will a water softener help my water heater?

Yes. Softened water greatly reduces scale buildup in tanks and tankless units.
