Sizing to your household
We size the new tank to how many people live there and how you use hot water, not just to the label on the old one.
Water Heater Replacement · Great Falls, VA
Quick answer
LeMaster Plumber replaces water heaters in Great Falls estate homes, from Seneca and Riverbend to Colvin Run and the Georgetown Pike corridor. Many homes here run on private well water, and minerals from a well can shorten a tank’s life, so when we pull the old unit we look at the sediment inside and talk through whether treatment makes sense. Call (703) 832-9090 to go over your setup.
Large Great Falls homes often have more than one water heater, or one big unit serving long pipe runs to the far side of the house. On well water, the heater sits downstream of the pressure tank and any treatment equipment, and we reconnect it without bypassing softeners or filters. Hard or iron-rich well water can wear out anode rods fast, so we may suggest checking the new rod on a schedule. When draining the old tank, we keep sediment-heavy water out of the septic system. Fairfax County requires a permit for replacement, even like-for-like; we pull it and handle the inspection.

Gas and electric tank water heaters installed with new connections, shutoffs and a fresh temperature-and-pressure relief valve.
On gas units we check the flue and draft so exhaust leaves the house. We fit expansion tanks and drain pans where the system or location calls for them.
Water heater replacement is permitted work. We pull the permit and handle the inspection so you do not have to.
We drain and remove the old tank and take it with us. You are left with a working heater and a clean space.
If you keep running out of hot water or need the floor space, we will walk through whether a tankless unit fits your home.
We check its age, the leak or failure, the fuel type, the venting and the space, and confirm replacement is the right call.
You get the unit, the scope and the price before anything starts. You approve it first.

Why LeMaster Plumber
You approve the price before we start — no surprises and no pressure. You’ll always know the cost before any work begins.
Every job is backed by proper training, the right permits, and a workmanship guarantee.
We show up on time, protect your space, and leave the job cleaner than we found it.
Not if it’s done right. We shut off and reconnect around your pressure tank and any treatment equipment, bleed air from the lines afterward, and keep drained sediment out of the septic.
Sometimes. Homes with many bathrooms or a far guest wing may do better with two units, or a tankless unit near the far fixtures. We look at your layout and usage before suggesting it.
Well water with high mineral or iron content builds sediment and uses up the tank’s anode rod faster. Most tanks last roughly 8–12 years; on hard well water it can be less. Treatment and regular flushing help the next one last.
