Water heaters fail on their own schedule, and in Baltimore-area homes hard water makes that schedule shorter. ProStream Plumbing repairs, replaces and installs tank and tankless water heaters across Baltimore City, Baltimore County, Anne Arundel County and Howard County — with an honest read on whether your unit is worth fixing.
Repairs We Handle
- No hot water: pilot, thermocouple, gas valve, elements and thermostats.
- Not enough hot water or long recovery times from sediment buildup.
- Leaks at fittings, valves, the T&P relief valve and supply connections.
- Rumbling, popping and knocking caused by sediment on the tank floor.
- Discolored or smelly hot water from a spent anode rod.
- Tankless error codes, scale buildup, ignition and venting issues.
When Replacement Is the Better Investment
A tank that is leaking from the vessel itself cannot be repaired — the steel has corroded through and the only question is how long before it opens up completely. Beyond that, age matters: putting a two-hundred-dollar part into an eleven-year-old tank buys time, not reliability.
We show you the unit's age from the serial number, explain the failure, and quote both options where both are real. If a repair will genuinely get you several more good years, that is what we recommend.
Installation Done to Code
A correct installation is more than swapping a tank. It includes proper venting and combustion air on gas units, thermal expansion control, a correctly configured T&P discharge, dielectric protection at the connections, seismic and drain pan requirements where applicable, and permitting with inspection.
The shortcuts that make a cheap install cheap — reused flex connectors, undersized venting, no expansion tank — are the ones that shorten the life of the new unit or create a safety problem.
Hard Water Is the Local Variable
Mineral content across much of the region drives sediment in tanks and scale in tankless heat exchangers. Annual flushing extends life meaningfully, and for households on the harder end, whole-home water filtration or softening protects the water heater and every fixture downstream of it.
