Water Heater Maintenance

A yearly visit that adds years to your water heater.

Most water heaters fail early for the same reason: nobody touches them until they leak. AccuFlow provides water heater maintenance in Lodi, Acampo and nearby towns. We flush out the sediment and scale that build up in the tank, check the anode rod, test the temperature and pressure relief valve, and confirm the venting and gas connections are safe. A clean tank heats faster, runs quieter and lasts longer. We also install thermal expansion tanks where a home needs one.

Tank Flush & Sediment Removal

Sediment drained out before it hardens, so the burner or elements stop working overtime.

Anode Rod Check & Replacement

The rod that protects the tank from rust, checked and replaced before it is used up.

Safety Checks

Relief valve tested, venting and gas connections inspected, and temperature set correctly.

Expansion Tanks

Expansion tanks installed where a closed system needs one.

What a water heater flush does

Hard water carries minerals that settle to the bottom of the tank as sediment. On a gas heater, that layer sits between the burner and the water, so the burner runs longer and the tank pops and rumbles. On an electric heater, sediment can bury the lower element until it burns out. A water heater flush drains that sediment out through the drain valve before it hardens. We also check the anode rod, the metal rod that corrodes so the tank doesn’t; once it is used up, the tank starts to rust from the inside. Replacing a worn anode rod is one of the cheapest ways to add years to a tank.

Signs your water heater needs maintenance

  • Popping or rumbling noises from the tank
  • Rust-colored hot water
  • Hot water not as hot as it used to be
  • The relief valve dripping or the discharge pipe wet
  • Rust on the fittings or at the base of the tank
  • The tank is several years old and has never been flushed

Expansion tanks

When water heats, it expands. If your home has a pressure regulator or a check valve, that extra volume has nowhere to go, and pressure spikes every time the heater runs. Over time that strains the tank, the relief valve and your fixtures. A thermal expansion tank gives the water somewhere to go. Many installations require one, and we check for it on every maintenance visit and every water heater install.

Tankless owners

Tankless water heaters need maintenance too, just a different kind: yearly descaling through the service valves and a clean inlet filter. See tankless water heaters for details, or water heater repair if your unit is already acting up.

What affects the cost of water heater maintenance

  • Tank type and size: gas, electric or tankless, and the tank capacity.
  • Sediment: a tank that has never been flushed takes longer to clear.
  • Parts: an anode rod, drain valve or relief valve if one is worn.
  • Expansion tank: adding one if your system needs it.
  • Access: a garage heater is quicker than one in an attic or tight closet.

What customers say

★★★★★

Phenomenal customer service. My 4 yr old tankless water heater (Rheem) failed at 9pm. I called AccuFlow Plumbing @ 7am the next morning for help. They arrived @ 10am and I had hot water by 10:30am after replacing the main control board. They took care of the warranty of the parts and flushed the system for calcium buildup!

Worked patiently with me to get my warranty work performed at no cost to me on my hot water heater. They worked into the evening to complete the job because there were elderly people in the home.

Common Questions

Water Heater Maintenance FAQs.

Once a year is a good rule for most homes. Heavy use or hard well water may need it more often.
It's a metal rod inside the tank that corrodes instead of the tank. Once it's used up, the tank starts to rust. Checking it every few years and replacing it in time can add years of life.
Most homes with a pressure regulator or check valve do, and code requires one in many cases. It protects the water heater and plumbing from pressure spikes.
Yes, if you're comfortable shutting off the gas or power and handling hot water. On older tanks, the drain valve can stick or start leaking once it's opened, and heavy sediment can clog it; that's when a plumber helps.
That's usually sediment on the bottom of the tank. Water trapped under it boils and pops as the burner heats it. A flush often quiets it down; if the tank is old and heavily scaled, it may be near the end of its life.
