An Oakton Plumber Who Starts With the Symptom

Brick Street Plumbing Heat & Air offers water heater repair in Oakton, VA 24/7, and there are no overtime fees, so a late call costs the same as a midday one. Our licensed plumbers fix gas, electric and tankless water heaters. Most repairs come down to a worn part: a heating element, a thermostat, a thermocouple, an igniter, a gas valve or a relief valve. We test before we replace, so you pay for the part that actually failed and not a string of guesses. If the tank has rusted through, we tell you plainly.

Oakton is an unincorporated community in central Fairfax County, known for wooded lots and quiet residential streets between Vienna and Fairfax. Most homes are single-family houses with the water heater in a basement or garage, and some properties in this part of the county draw from private wells instead of public water. That difference matters, since well water can carry minerals and sediment that build up inside a heater faster. As an Oakton plumber, we work on both kinds of homes and the plumbing systems around the heater.

Symptom and Likely Cause

A quick guide to what your water heater might be doing and what is usually behind it.

No hot water, electric tank

Check the breaker first. If it is on, the reset button on the upper thermostat may have tripped, or an element has burned out.

No hot water, gas tank

The pilot may be out. A pilot that will not stay lit usually means a failing thermocouple or gas control valve.

Hot water runs out early

Sediment, a failed lower element or a broken dip tube. Well water with heavy sediment makes this more common.

Discolored or gritty water

Rust-colored hot water suggests a worn anode or corrosion. Grit may be sediment from the well or pieces of a broken dip tube.

Tankless unit shows an error

Scale buildup, a clogged inlet screen or an ignition fault. Write the code down before you call. It speeds up the diagnosis.

Water on the floor

Could be the relief valve, a fitting, the drain valve or the tank. Shut the cold supply and power off, then call.

WELL WATER HOMES

Private Wells Are Harder on Water Heaters

Water from a private well is not treated before it reaches the house, so whatever minerals and sediment it carries go straight into the heater. Hard water leaves scale on elements and tank bottoms. Iron can stain fixtures and feed bacteria that cause a sulfur smell in the hot water. The heater is often where those problems show up first. Treating the water at the source protects it and every fixture downstream. We install whole-house water filtration and water softeners, and our plumbers also service the equipment that brings the water in, including well pumps. On a well, a weak pump or failed pressure tank can look like a water heater problem, since low pressure affects hot and cold alike. If you are not sure which side the problem is on, run a cold tap and a hot tap at the same sink. Weak flow on both points toward the well system. Weak or cloudy flow on the hot side only points toward the heater.

Fantastic service - bought a home with a very old hot water heater, and Brick Street’s quote came out to be substantially less than the other plumbers I spoke with. No compromise on service for the price, though - Mary was incredibly responsive and friendly when it came to scheduling a time to install the new water heater, and Tylerr did an outstanding job getting the water heater set up and running. Overall very easy to work with, reasonably priced, and professional!

⭐⭐⭐⭐⭐ Excellent Service – Highly Recommend Brick Street Plumbing Water Heaters I recently had my entire HVAC system replaced after my old unit had been in my home for over 20 years. I requested an estimate through Home Depot, and they referred me to Brick Street Plumbing. Water Heaters, From beginning to end, my experience was excellent! Brian came to my home, carefully explained the different options available, and walked me through the entire installation process. He was very professional, knowledgeable, patient, and always available to answer my questions. Communication with Brian was outstanding throughout the entire project. One of the best parts of the installation was that they were able to relocate my water heater into an unused space in my basement. This made the entire HVAC area much more spacious, organized, and accessible. I am extremely happy with how everything turned out! I also want to recognize Austin, Gmo, and Dani for their excellent work. They were professional, hardworking, respectful of my home, and paid great attention to detail. The entire team did an amazing job! Replacing an HVAC system is a major investment, but Brick Street made the entire experience smooth and stress-free. I am extremely satisfied with the quality of their work, professionalism, and customer service. I highly recommend Brick Street to anyone looking for a reliable company for HVAC installation or replacement.

Update 10/2/2026 The manager got in touch with us and promptly sent out a service technician that was able to quickly diagnose and troubleshoot the issue with our thermostat. ------------------------------------------------------------------------------------------------------ We got our AC replaced by Brick Street through Home Depot. After a week our AC wasn't working so we had to put in a service call. They came out and fixed it. Then our heating wasn't working and we put in a service call to have a tech come out to and troubleshoot but their HVAC department has been non responsive via email or voice mail. We are not able to get in contact with them at all. Will not be doing business with this company again. Very poor customer service.

Frequently asked questions

How do I reset an electric water heater in Oakton?

Turn off the breaker for the heater first. Remove the upper access panel and the insulation behind it, then press the red reset button above the thermostat. Replace everything and turn the breaker back on. If the reset trips again, do not keep pressing it. Repeated tripping usually means a shorted element or failing thermostat, and a plumber should test them. If you are not comfortable working near the wiring, call us instead.

Does well water damage a water heater faster?

It often does. Well water is untreated, so minerals and sediment settle in the tank or build scale in a tankless heat exchanger. That can shorten the heater's life, reduce hot water capacity and cause rumbling noises. Flushing the tank once a year helps. For a longer fix, a water softener or whole-house filter treats the water before it ever reaches the heater, and it protects faucets and appliances too.

What should I look for in a plumber in Oakton, VA?

Look for a licensed company that answers when you call, explains the problem before it starts work, and has a track record you can check. Brick Street Plumbing Heat & Air has licensed, dual-certified technicians for plumbing and HVAC, is available 24/7 with no overtime fees, and carries 4.6 stars across 282 Google reviews. Ask any plumber you consider to explain repair and replacement options in plain terms.

Why does my hot water smell like sulfur but my cold water does not?

This is common in homes on wells. Bacteria in the water react with the magnesium anode rod inside the tank and produce hydrogen sulfide, which smells like rotten eggs. Since the reaction happens in the heater, only the hot side smells. Swapping the anode for a different type and flushing the tank usually solves it. If both hot and cold water smell, the source is the well, and treatment may be needed.

What size water heater does a typical Oakton home need?

The right size depends on how many people live in the house and how much hot water they use at the busiest time of day, not just the number of bathrooms. A household that runs two showers and a dishwasher at once needs more capacity than one that spreads use out. For tankless units, the measure is flow rate rather than tank size. We ask about your routine and recommend a size that matches it, which avoids both cold showers and wasted energy.
