Our Water Heater Services

Repair, Replace, or Upgrade?
Not every water heater problem means replacement. Some issues are isolated and repairable, while others — a failed tank, an aging unit, frequent repairs, or unsafe conditions — point to replacement. We evaluate the condition, safety, age, and performance of your unit before recommending the right path.
If you are weighing a standard tank against a tankless upgrade, we explain the practical trade-offs based on your hot-water demand, fuel type, and existing connections.

Common Water Heater Problems
Water heater problems can show up as no hot water, not enough hot water, inconsistent temperature, water around the tank, unusual noises, rust-colored water, pilot problems, or tripped breakers. These symptoms should be diagnosed before assuming the unit needs to be replaced.
If you smell gas, see active leaking, or notice water near electrical components, stop using the affected equipment when safe to do so and call for service. For a suspected gas leak, leave the area and contact 911 and the gas utility from a safe location.
Why Licensed Plumbing Experience Matters
Water heater work can involve plumbing connections, gas safety, venting, electrical connections or controls within plumbing service scope, code requirements, and repair-versus-replacement decisions. A proper diagnosis helps avoid unnecessary parts replacement while identifying unsafe or failed conditions.
Work is performed by or under the supervision of a Responsible Master Plumber licensed by the Texas State Board of Plumbing Examiners (TSBPE), in accordance with applicable state and local plumbing codes.

Frequently Asked Questions
Should I repair or replace my water heater?
Repair may make sense when the issue is isolated to a serviceable component or connection. Replacement may be better when the tank has failed, the unit is near the end of its service life, repairs are frequent or costly, or the installation is unsafe. We evaluate the condition and age of the unit before recommending a path.
Do you work on gas and electric water heaters?
Will's Plumbing & Testing Service evaluates gas and electric water heater problems within the appropriate plumbing service scope. If a problem requires electrical work outside that scope, we explain the concern and recommend the appropriate next step.
Should I consider a tankless water heater?
Tankless can offer continuous hot water, a smaller footprint, and efficiency benefits, but the right choice depends on your usage, fuel type, and existing connections. We explain the trade-offs for your specific home.
