The $30 part that saves the $1,000 tank
Water Heater Maintenance & Flush Service in Katy, TX
Most water heater 'failures' are years of skipped maintenance coming due at once. An annual visit keeps the sediment out, the anode fresh, and the repair calls rare.
What maintenance actually prevents
Sediment collects at the bottom of every tank and hardens into a layer that traps water beneath it — that's the popping and rumbling you hear when the burner fires, and it insulates the tank from its own heat source, driving up energy bills while accelerating wear. An annual flush removes it before it sets.
Meanwhile the anode rod quietly corrodes — by design. It's a sacrificial part that attracts corrosion away from the tank walls; once it's consumed, the tank itself starts rusting from the inside, which is why hot-side discoloration is often the first sign a tank's years are numbered. Replacing the rod on schedule is the single best way to extend a water heater's lifespan.
The annual visit, itemized
A maintenance visit covers the full checklist: tank flush and drain, anode rod inspection, T&P relief valve test, thermostat verification at 120°F, and a component health check on elements, dip tube, connections and venting. For tankless units, the visit is a descaling flush that clears mineral buildup from the heat exchanger.
It pairs naturally with our plumbing maintenance membership — the schedule becomes automatic, and small findings get fixed at member pricing before they become failures.
What we handle
Water Heater Maintenance work we handle every week
Annual Tank Flush
Draining sediment before it hardens prevents the rumbling, popping and efficiency loss that lead to early failure — especially in Katy's moderately hard water.
Anode Rod Inspection
The sacrificial rod attracts corrosion away from the tank walls. Checked every visit, replaced every 3–5 years — a $30–50 part protecting a $1,000+ tank.
T&P Valve Testing
The temperature and pressure relief valve is a safety device — we verify it opens and closes properly. A stuck valve is a hazard, not a maintenance note.
Temperature Optimization
We set and verify 120°F — hot enough for comfort, low enough to prevent scalding and cut energy use.
Tankless Descaling
Tankless units in Katy's hard water need an annual descaling flush to keep the heat exchanger at peak efficiency.
Component Health Check
Thermostats, elements, dip tube, connections and venting inspected — worn parts caught at the maintenance visit instead of the 2 AM failure.

281-601-1513How often should a water heater be flushed?
Annually for most Katy homes — our moderately hard water builds sediment faster than soft-water regions. Homes with a water softener can sometimes stretch the interval; the maintenance visit tells us.
What does the anode rod do?
It's a sacrificial part designed to corrode instead of your tank — attracting corrosion away from the tank walls. Checked at every maintenance visit and replaced every 3–5 years, it's the cheapest lifespan extension in plumbing: a $30–50 part protecting a $1,000+ tank.
Does a tankless unit need maintenance too?
Yes — Katy's hard water deposits mineral scale inside the heat exchanger. An annual descaling flush keeps a tankless unit at peak efficiency and protects its 20+ year lifespan.
Is maintenance included in a membership?
Our plumbing maintenance membership covers the annual water heater service with priority scheduling and member pricing on any repairs it surfaces.
