How to Maintain your Hot Water Heater

Regular Flushing

Sediment build’s up at the tank’s bottom over time, interfering with proper heat distribution, which negatively impacts heating components.
Periodically flushing the tank helps remove sediment and keep it clean.

Water tanks contain an anode rod of sacrificial metal, which attracts minerals, like calcium, to it’s surface. These rods are meant to corrode instead of the tank, so need to be inspected for significant wear and replaced if they are depleted (3-5 years on average).

This valve helps to maintain a safe and proper amount of pressure in your tank. If the pressure builds up past recommended limits, the valve will open, releasing a small amount of water or steam. This helps prevent wear and tear on the system due to excessive pressure.

In closed water systems, thermal expansion can occur, putting stress on the tank. Installing an expansion tank helps absorb excess pressure, reducing strain on the tank and other components.

Many of these steps require a trained professional to perform safely. Beyond these tips, a professional inspection will catch small issues before they turn into big problems. Leaks, corrosion, and faulty components can cause catastrophic failure, so it’s important to catch them before that happens!

We had Gerry plumb in a new shower in the basement in our home as well plumb in a new washer/dryer at our business. We found Gerry to be reliable, honest and very fair with his fees. He communicated great throughout the job so there were no surprises. We will certainly be using Gerry for any future plumbing needs we have!

I was very impressed with Gerry and the service he provided me. My dishwasher was not draining ( was not plumbed into the kitchen sink as most are). Gerry was able to pinpoint where the piping went into my down stairs ceiling and found the blockage in a p trap behind the drywall. He was organized, professional and his pricing was great. Best part was, he was able to attend the day after I called him. Would highly recommend

We recently got a new gas line brought into our house and Gerry plumbed in everything for a range, hot water, furnace and even an outside BBQ! We were thrilled with his professionalism and work ethic.

I had a fast worsening leak and called Gerry King Plumbing on a Saturday to see if he could help. He answered right away and arrived an hour later! I found him to be fast, friendly, and professional. He quickly figured it out and had the fix all done in a short period of time. Friendly and easy to get along with also, which is always nice. Will use again, and a well earned 5 star rating for Gerry King Plumbing and Heating.

Frequently Asked Questions

There are a few signs that your hot water tank may need to be replaced:
Age – Most tanks last 8–10 years. If yours is older, it may be time for a new one.
Leaks or Rust – Water pooling around the base or rust on the tank means replacement is needed.
Inconsistent Hot Water – If you’re running out of hot water faster than usual, the heating element may be failing.
Strange Noises – Rumbling or banging sounds are caused by sediment buildup, which reduces efficiency.
Higher Energy Bills – Aging units have to work harder, costing you more in utilities.

Not sure? Call us for a quick inspection!

A standard hot water tank installation typically takes 2–4 hours, depending on:

  • The type and size of the tank
  • Whether old pipes or connections need replacing
  • Gas vs. electric hookups (gas may take longer due to venting requirements)

We offer same-day installations whenever possible.

The right size depends on your household size and hot water usage:

  • 1–2 people: 30–40 gallons
  • 3–4 people: 40–50 gallons
  • 5+ people: 50–80 gallons
  • Tankless systems provide endless hot water and may be a better option in the right circumstances.

We can help you choose the right size based on your needs.

We work with all major water heater brands, including:

– Rheem
– Bradford White
– A.O. Smith
– Navien (for tankless systems)
– Giant
– John Wood

If you have a specific brand preference, let us know!
