Tank or tankless, gas or electric -- our licensed technicians diagnose your water heater fast and restore hot water the same day in most cases.
Why Choose Us
Water heater repairs require accurate diagnosis before any parts are replaced. We get it right the first time.
All water heater work is performed by fully licensed plumbers. Gas line work requires certified technicians -- we hold the credentials.
No hot water is a household disruption. We prioritize water heater calls and offer same-day service throughout most of Washington, DC.
We diagnose the unit, explain the issue, and quote a fixed price before any repair begins. No hourly billing that escalates as the job progresses.
We carry multimeters, combustion analyzers, sediment flush equipment, and a range of common replacement parts -- anode rods, heating elements, thermostats, and pressure relief valves.
Water heater problems tend to fall into recognizable patterns depending on the unit type, age, and fuel source. Our technicians follow a structured diagnostic workflow that identifies the failing component before recommending any repair, which prevents unnecessary parts replacement and keeps costs reasonable.
For traditional storage tank heaters, the most common issues we encounter are: sediment buildup that reduces heating efficiency and causes rumbling or popping sounds; a failed heating element (electric) or a malfunctioning burner assembly (gas); a deteriorated anode rod that allows tank corrosion to accelerate; and a faulty thermostat that produces inconsistent water temperature. Sediment accumulation is particularly prevalent in areas with hard water, and a tank that has never been flushed will lose meaningful capacity and efficiency over time. Annual flushing adds years to a tank's service life at minimal cost.
For tankless water heaters, the diagnostic process is more involved. Tankless units are controlled by an electronic flow sensor, a heat exchanger, and a control board that reads from multiple temperature sensors. Scale buildup inside the heat exchanger is the most frequent cause of efficiency loss and error codes. We perform descaling flushes using a food-grade descaling solution circulated through the unit with a pump -- a service that should be performed annually in hard water regions. Other common tankless failures include a worn flow sensor, a failed igniter on gas models, or a venting obstruction that triggers safety shutoff.
The repair versus replace decision is one we take seriously. A tank unit less than 8 to 10 years old that experiences a single component failure is almost always worth repairing. A tank that is beyond 12 to 15 years old, showing rust-colored water, or experiencing multiple simultaneous failures is typically more economically replaced. We walk you through the age of your unit, the estimated remaining lifespan post-repair, the repair cost, and the replacement cost with the new unit's improved energy efficiency -- so you make the decision with complete information, not sales pressure.
When replacement is the right call, we carry a range of tank and tankless options and can complete installation the same day in most cases. We also advise on sizing -- an undersized replacement is a common mistake that leaves households with the same run-out-of-hot-water problem the old unit had.

Customer Stories
"My water heater was making a loud rumbling noise and the hot water kept running out quickly. The technician from Process Plumbing Services diagnosed sediment buildup immediately, flushed the tank, replaced the anode rod, and it has been perfect ever since. Great value."
"Woke up to no hot water. Called Process Plumbing Services at 8am and a tech was here by 11am. The heating element on my electric tank had burned out. He had the part on the truck, replaced it in about an hour, and I had hot water by lunch. Could not ask for better service."
"I was told by another company I needed a full replacement. Process Plumbing Services gave me a second opinion, identified a faulty thermostat, and repaired it for a fraction of the replacement cost. Honest, skilled, and clearly explained everything. My go-to plumber now."
