Hot water back
Often same day
The basics
How a tank water heater works
A standard tank water heater, also called a hot water heater, stores 40 to 75 gallons of water and keeps it hot and ready. Cold water enters through a dip tube to the bottom of the tank, where a gas burner or electric elements heat it. A thermostat holds your set temperature, and hot water is drawn off the top as you use it. Inside, a sacrificial anode rod protects the steel tank from rust, and a temperature and pressure relief valve keeps things safe. When any of these parts wear out, you feel it as cold water, rusty water, or strange noises. The good news is most of it is repairable, and when it is not, a clean replacement is quick.
What we do
Water heater services
Repair, replacement, installation, and the maintenance that makes a tank last.
Water Heater Repair
No hot water, leaks, pilot or igniter trouble, bad thermostats, heating elements, and gas valves diagnosed and fixed.
Water Heater Replacement
Old, leaking, or undersized tank? We haul off the old unit and install a right sized replacement, code compliant, the same day in most cases.
New Installation
Adding a unit, finishing a basement, or upgrading capacity. We size it correctly and install it to last.
Gas & Electric
We service and install both gas and electric tank water heaters from the brands we trust, and help you pick the right fit.
Anode Rod & T&P Valve
Replacing a spent anode rod can add years to your tank. We also test and replace temperature and pressure relief valves for safety.
Tank Flush & Maintenance
Annual flushing clears the sediment that Maryland hard water leaves behind, restoring efficiency and protecting the tank.
How it works
From cold water in to hot water out
Four things happen inside the tank every time you turn on the hot tap.
1
Cold water in
Fresh water enters through a dip tube and fills the bottom of the tank.
2
Burner or element heats
A gas burner below or electric elements inside warm the water to your setting.
3
Thermostat holds temp
The thermostat cycles the heat to keep a full tank of hot water ready to go.
4
Hot water out
Hot water rises and is drawn off the top to your showers, sinks, and appliances.
Catch it early
Signs your water heater is failing
Spot these early and a repair is often all you need. Ignore them and you risk a cold morning or a flooded floor.
No hot water, or not enough
A failed element, burner, thermostat, or pilot, or simply a tank too small for your household.
Rusty or smelly water
Brown water or a rotten egg smell usually points to a spent anode rod or sediment in the tank.
Rumbling or popping noises
Sediment hardened on the bottom makes the tank work harder and bang as it heats.
Water pooling at the base
A leaking tank rarely gets better. This is the clearest sign it is time to replace before it bursts.
Slower reheat or higher bills
Sediment and aging parts make the heater run longer and cost more to do the same job.
Eight or more years old
Tank heaters typically last 8 to 12 years. Past that, plan a replacement before it fails on you.
Spot any of these? Don't wait for a cold morning.

Know your options
Gas, electric, and the right size
We help you weigh fuel type and capacity so you are not paying for more than you need, or running out mid shower.
Gas Tank
Heats quickly and recovers fast between uses, often cheaper to run where natural gas is available. Needs proper venting, which we handle.
Electric Tank
Simple, no venting required, and a great fit for homes without a gas line. Recovery is a little slower, so sizing matters more.
Right Sizing
A 40 gallon tank suits smaller homes, 50 gallons fits most families, and 75 gallons covers big households. We size to your real use.
Curious about going tankless for endless hot water and lower bills? Ask us about a tankless upgrade when we visit.
Built for Maryland homes
Hard water is hard on tanks
Much of Montgomery and Frederick County runs hard water, which leaves mineral sediment in the bottom of your tank. That sediment is the number one reason heaters get noisy, lose efficiency, and fail early. A yearly flush and a healthy anode rod are the simplest way to get the full life out of yours.
- Flush the tank once a year to clear sediment
- Check the anode rod every few years and replace when spent
- Test the temperature and pressure relief valve for safety
- Consider whole house filtration to slow sediment buildup

Absolute best plumbers I have ever used. Needed them a few times recently and each time they were so professional, kind and resolved each problem the first time around. This last issue took them several hours to fix. They explained everything along the way and gave a very fair price for a lot of work. They also work very cleanly! I will never use another plumber! I wanted to add a new review but I could not so I am editing my previous one. I had to use Clarksburg Plumbing again today and like last time, they were exceptional. I was fortunate enough to have John and Madeleine as my service technicians. I will always request them going forward. They are kind, professional and knowledgeable! I am sure the company knows how fortunate they are to have them as part of their team!

We thank Clarksburg Plumbing again for superior, high quality and friendly service! ----- Clarksburg Plumbing visited us last week to repair an external spigot that had been leaking. The work involved creating a little inside access panel. Within and without, a nice, neat job by Charlie and his understudy apprentice, Chris. Problem solved and happy campers here! ----- UPDATE: Plumber John Brown presented himself on time and got right to work replacing my Mom's ancient leaky kitchen faucet with a new store-bought one that I provided. During the process, Mr. Brown detected and showed me two other problem areas contributing to the water leaks: a cracked drain pipe and then rusted threads on the sink trap. He efficiently and expertly repaired all three elements to our full satisfaction. Plus, John is a super nice guy, completely honest and classy enough to laugh at all my corny jokes! The next time you need any plumbing work in your home or business, I strongly endorse John Brown and anyone on the Clarksburg Plumbing team! UPDATE 2: John and his understudy Maddie visited, and quickly solved the problem of a pinhole leak in copper tubing leading from our hot water heater. He advised us on other plumbing needs, for which we have scheduled and will otherwise follow-up. Thank you Clarksburg Plumbing for your top quality people - John Brown in particular - and performance.

Tevon, Noah, Markell, and Morrow were sent by Clarksburg Plumbing LLC to repair an outside broken waterline They arrived at the appointed hour and completed the work in about 3 hours. I was very impressed with them and I would like to recommend all four of these very professional and friendly technicians.

Thank you to Seth, who came on Wednesday and fixed one of our two toilets and fixed our primary bedroom shower. And thank you to Charlie, who came today and replaced our other toilet and replaced our garbage disposal. You are both lifesavers! Our weekend (and going forward) will be MUCH nicer now that we can use our bathrooms (and garbage disposal) again. Highly recommend Clarksburg Plumbing.

GREAT service and expertise! John and Maddie just installed a water filtration system to our home. The process took one day to install and then they came back from the 48 hour install period to ensure everything was working well. John was familiar and knowledgeable about the water system we bought. Maddie and John kept our space clean, clearly explained how to ensure longevity for our system to last, and the difference it will make in our home. We appreciate their hard work and professionalism. This is our second time using Clarksburg plumbing. We would highly recommend their company to our family and friends.

Franklin and his crew showed up promptly and communicated great with us to help limit disruption with the tenants at 4 of our building. Unfortunately for us a second water main leak occurred the day before. But luckily for us they were able to stay on site another 2 days and knock the second one out, even staying till 8pm to find the line and get it repaired. These will be the guys I request for our next time needs

Good questions
Water heater FAQ
What homeowners ask us most about tank water heaters.
How long does a tank water heater last?
Most tank water heaters last 8 to 12 years. Hard water and skipped maintenance shorten that, while an annual flush and a fresh anode rod can stretch it. If yours is in that range, it is wise to plan ahead rather than wait for a cold morning.
Should I repair or replace my water heater?
If the tank is under about 8 years old and the issue is a part like a thermostat, element, igniter, or valve, repair is usually the smart call. If it is leaking from the tank, very old, or repairs are stacking up, replacement is the better value. We give you the honest math either way.
What size water heater do I need?
As a rough guide, a 40 gallon tank suits 1 to 2 people, 50 gallons fits most families of 3 to 4, and 75 gallons serves larger households or homes with big tubs. We size it to how you actually use hot water, not just square footage.
Why do I have no hot water or run out quickly?
Common causes are a failed heating element or thermostat on electric units, a pilot or burner problem on gas units, a tripped breaker, or sediment stealing capacity. If you run out fast, the tank may also be undersized for your household.
Why is my hot water rusty or smells like rotten eggs?
That is almost always the anode rod and sediment. The anode rod sacrifices itself to protect the tank, and when it is spent you get rusty water or a sulfur smell from bacteria reacting in the tank. Replacing the rod and flushing the tank usually clears it up.
Gas or electric, which is better?
Gas heats and recovers faster and often costs less to run where natural gas is available, but it needs proper venting. Electric is simpler, needs no venting, and fits homes without gas. We help you choose based on your home and your budget.
Do you install tankless water heaters too?
Yes. If you want endless hot water and lower standby energy use, we can walk you through a tankless upgrade and whether it makes sense for your home. Just ask when we visit.
Are you licensed, insured, and available for emergencies?
Yes. We are fully licensed and insured, every technician is background checked, and we are available 24/7 for plumbing emergencies across Clarksburg, Gaithersburg, Germantown, and the surrounding Montgomery and Frederick County area. Call 301 972 2223 any time.
