When an Olney water heater stops producing enough hot water, the fix is often a heating part, a gas control component or a good flush rather than a new tank. If water is coming through the tank wall, it has to be replaced. Call the number on this page to be connected with a local plumber in Olney.
Local conditions in Olney
Olney was mostly farmland until the 1960s, and its homes are relatively young; census-based figures put the median year built around 1986. That puts a lot of houses on their second or third heater, often in a basement utility room. Core Olney is on WSSC Water, and northern Olney borders the Triadelphia and T. Howard Duckett reservoirs on the Patuxent River, part of WSSC's supply. WSSC's tap water analysis lists average hardness of about 64 mg/L for Patuxent plant water and about 140 mg/L for Potomac plant water; which plant serves a given address varies. WSSC disinfects with chlorine rather than chloramine.
A few outlying properties are different. Public water was extended to Mt. Zion to relieve well problems, and some properties on the rural edges sit outside the public sewer envelope and use a private onsite wastewater system. If your home is on a private well, its water chemistry can affect the tank as much as anything WSSC does.
Repair, flush or replace
| Situation | Usual outcome | Why |
|---|---|---|
| Electric unit, tripped reset or dead element | Repair | Elements and thermostats are standard parts |
| Gas unit, pilot or igniter fault | Repair | Small component on a sound tank |
| Rumbling, short supply, no leak | Flush, then reassess | Sediment may be the whole problem |
| Relief valve discharging | Test pressure and temperature, replace valve | A safety device doing its job, or wearing out |
| Rust and seepage at the tank base | Replace | Corrosion inside the tank can't be repaired |
Signs to watch for
- Hot water that turns lukewarm sooner than it used to
- Popping sounds when the heater fires
- Discolored or metallic-tasting hot water
- A wet floor or damp drywall near the unit
- A pilot that keeps going out
Timing notes
Cold winter supply water makes a heater work harder, so weak units tend to fail between December and February. A flush and a relief valve check in the fall cost far less trouble than a failure on the coldest night of the year. If you ever smell gas near the heater, leave the house first, then call 911 and your gas utility from outside; the emergency number is printed on your gas bill. Gas water heater replacements in Montgomery County must be handled by a plumber or gasfitter registered with WSSC Water under a WSSC permit.
