Water Heater Maintenance in Denver

Denver's hard water is the number one enemy of water heater longevity. Annual flushing, anode rod checks, and safety inspections from Done's licensed plumbers keep your unit running efficiently and lasting years longer.

Denver Hard Water Demands Regular Maintenance

Water Heater Maintenance That Pays for Itself

Denver’s tap water is among the harder in the Front Range — high in dissolved calcium and magnesium that settles as scale inside your water heater tank and on heating elements. Left unchecked, that sediment layer forces the unit to burn more energy to heat the same amount of water, shortens the life of heating elements, and eventually cracks tank liners from excess heat. Annual maintenance is the simplest, least expensive way to prevent all of that.

Done’s water heater maintenance visit covers a full flush to remove sediment, an anode rod inspection (the sacrificial component that prevents tank corrosion), thermostat calibration, and a T&P valve test. It’s also a good opportunity to catch small issues before they turn into an emergency call. Learn more about the full range of water heater services we offer, or call 833-539-9153 to get on the schedule today.

  • Extends Equipment Life Regular maintenance — especially in Denver's hard-water environment — can add years to your water heater's lifespan by preventing the sediment buildup and corrosion that cause premature failure.
  • Keeps Efficiency High A layer of sediment as thin as a quarter inch can measurably increase energy use. Flushing your tank annually keeps heating elements direct contact with water and your utility bills in check.
  • Safety Check Included Every maintenance visit includes a T&P valve test and visual inspection of all connections and venting. Catching a failing safety valve early is the difference between a service call and a flooded utility room.

Overdue for Maintenance?

Signs Your Water Heater Needs a Flush and Inspection

Most water heaters in Denver should be serviced once a year. These are signs yours may be overdue.

  • Rumbling or Popping Sounds

    That knocking sound when the burner fires? That's hardened scale being heated and cracking. It means sediment has built up to the point where it's audible — and it's working your unit harder than it should.

  • Slower Hot Water Recovery

    If your tank takes noticeably longer to reheat after a shower or load of laundry, sediment insulating the heating elements is the likely culprit. A flush often restores recovery speed.

  • It's Been More Than a Year

    In Denver, annual maintenance isn't optional — it's how you protect your investment. If you can't remember the last time your water heater was serviced, it's time.

  • Slightly Discolored Hot Water

    Faint rust or murky color in hot water can mean the anode rod is depleted and the tank interior is beginning to corrode. Catching this early is the difference between a rod replacement and a full tank replacement.

What's Included

What Done's Maintenance Visit Covers

Our maintenance visit is a thorough inspection and service — not a quick once-over.

  • Full Tank Flush We drain and flush the tank to remove accumulated sediment from the bottom. In Denver's hard-water environment, this is the single most important step in maintaining efficiency and tank longevity.
  • Anode Rod Inspection and Replacement The anode rod sacrifices itself to prevent tank corrosion. Once it's depleted, the tank wall is exposed to rust. We check the rod at every visit and replace it when needed.
  • T&P Valve Test The temperature and pressure relief valve is your water heater's primary safety device. We test it to confirm it opens and closes properly — a stuck valve is a serious hazard.
  • Thermostat Check and Calibration We verify the thermostat is set and reading accurately. The recommended setting is 120°F — hot enough for comfort and sanitation, low enough to reduce standby heat loss and scalding risk.

Had an excellent experience with It's Done Plumbing and Jake the technician. He showed up early, gave me an accurate estimate and finished the job to my complete satisfaction. Will definitely use their services again. 9/08/21 Had another plumbing issue and call Done again. Superb service. Caleb and Dalton did a terrific job. Fast, thorough, clean and helpful. I won't even consider calling anyone else. 2/7/23 Jared from Done came and cleared a slow basement drain. Quick, professional and left no mess. Done is the only plumbing service I use. Always satisfied. 3/1/24 I was considering having a tankless hot water system installed. I reached out to Done! to see about an estimate. The price was higher than I can afford right now. The price is in line with what others are charging. I didn't have any ideas going in, so this is not a knock on Done! Tankless systems are expensive. I never felt any pressure from the tech. He was professional and courteous. 4/21/26 Decided to have a preemptive cable clean out due to some roots from a holly plant. We weren't having an issue, just decided to stay ahead of it. Jason was quick, courteous and efficient. A good experience. 6/24/26 The fixture in the shower failed internally. It wouldn't allow the water to shut off. Dan fixed it in less than an hour. Completely satisfied, as usual. Done is reliable and reasonably priced. What more could you ask from a company? 8/9/26 The washing machine drain hose empties into a PVC pipe that then empties into the main drain. There was a clog somewhere. Done Plumbing sent Matthew out to clear it. He succeeded quickly and completely. The price was less than I imagined it would be. Completely satisfied, as usual. 8/17/26 The previous issue with the washer drain stand pipe was more complicated than it seemed. Turns out, the cast iron pipe under the basement floor had degraded to the point where the water drained very slowly. Justin identified the most efficient approach, both in cost and in time, to repair the issue. The concrete work was done on a single day, with minimal disruption to my household. Justin was terrific from start to finish. He kept me informed every step of the way. Done has always treated me fairly and quickly solved my plumbing issues. Highly recommended. Justin is the man!

I have been meaning to write this review for a bit. I found out about Done when I was at my friend's house where her sewer line was being cleaned out. I was impressed with Chris the technician and told him I planned to have some water faucets replaced at my house, including the old cold water shutoffs. I requested him for that work and everything turned out well. He coordinated with the city I live in to get the main water turned on/off, etc. More recently, Sean came over to do a tune-up on my A/C system outdoors. The twenty-two year old fan was making noise and the breaker and dual capacitor were also replaced. He also checked general function. Both Chris and Sean were professional and no call backs were needed. Additional Service on 8-4-26: Darrell came by to do a hot water flush for their $99 Special and I appreciated his detailed and careful approach when flushing my older 50 gallon water heater. He also provided quotes if I should decide to replace it soon with another tank water heater or a tankless version. He related how the tankless water heater might be installed. I could tell that he was one of their more experienced Plumbers.

Frequently Asked Questions

How often should I flush my water heater in Denver?

Once a year is the standard recommendation, but Denver’s hard water — which is high in calcium and magnesium — makes annual flushing especially important here. If your unit has never been flushed and is several years old, we may flush it twice in the first year to clear heavy buildup before moving to an annual schedule.

What is an anode rod and why does it matter?

The anode rod is a metal rod (usually magnesium or aluminum) suspended inside your tank. It attracts corrosive minerals in the water and corrodes itself so the tank walls don’t. Once the rod is depleted — typically every 3–5 years, sometimes sooner in hard water — the tank itself starts to rust from the inside. Replacing the rod is far less expensive than replacing the tank.

Can I flush my water heater myself?

You can, but there are a few things to be careful about: sediment-clogged drain valves that fail when opened, hot water burn risks, and T&P valve testing that requires knowing what to look for. Many homeowners prefer to have a licensed plumber handle it — it’s affordable and you get a full safety inspection included. Schedule with Done and we take care of the whole thing.

Does maintenance really extend the life of a water heater?

Yes — especially in Denver. Sediment buildup is a leading cause of premature water heater failure, and hard-water scale accelerates element burnout. Annual flushing removes that sediment before it causes damage. Homeowners who maintain their units regularly typically get several additional years of service compared to those who don’t.
