Plumber in Potomac, MD
Potomac homes are big, which changes the plumbing math: longer runs, more fixtures, recirculation loops, multiple water heaters and often well systems on larger lots.
Sizing matters more here than anywhere else we work, and getting it wrong is expensive.
Lud's Plumbing serves Potomac, MD with 24/7 emergency plumbing, tankless and traditional water heater installation, whole-house repiping, leak detection, filtration and drain and sewer service. Large Potomac homes carry high fixture counts, long hot water runs and multi-zone systems that need proper design rather than a parts swap.

What Potomac's housing stock means for your plumbing
Homes of different eras fail in genuinely different ways. Here is what we see most in this area.
1960s–1980s estate homes
Original copper reaching pinhole age across very long runs, plus recirculation loops that were never balanced and hot water that takes minutes to arrive at far fixtures.
1990s–2000s large builds
Multiple water heaters, high fixture counts and pressure zoning. Failures cluster around expansion tanks, pressure-reducing valves and recirculation pumps.
Properties on private wells
Larger lots often run wells with pressure tanks and filtration. Iron, sediment and hardness treatment is a routine part of the service here.

Potomac plumbing questions
Why does hot water take so long to reach my far bathroom?
In a large house that is a distance and recirculation problem, not a water heater problem. Either there is no recirculation loop, the pump has failed, or the loop was never balanced. Replacing the heater will not fix it.
Do you do whole-house water filtration?
Yes, and we size it from a water test rather than a catalog. On well properties that usually means addressing iron, sediment and hardness in the right order.
Can you find a leak without opening the whole ceiling?
That is the point of proper leak detection. We locate the failure first, then open the smallest section that lets us make a durable repair.
