Water Heater Repair in Dallastown, PA
More than half of Dallastown's homes are rented, and one in three was built before 1940. Most heat with gas, and two gas companies list the borough. If your water heater has quit or is leaking, call and get a plumber out.
What shapes water heater trouble in Dallastown
A borough of renters
About 55% of Dallastown homes are rented. About 23% are rowhomes or twins and 20% are in buildings with five or more units. The borough requires every residential rental unit to be registered and inspected. For 2026, registration was $100 per unit, due by February 28, with a $10 late fee added for each month after that.
The borough's rental code also sets minimum safety devices: a carbon monoxide detector in any common hallway leading to sleeping areas and at least one on every level. That matters with a gas water heater in the basement. If you rent and the hot water goes out, or the CO alarm sounds, tell your landlord or the owner's agent, and for a CO alarm, get everyone outside first.
Red Lion's water, the borough's pipes
The Dallastown-Yoe Water Authority owns the pipes that serve Dallastown, Yoe and part of York Township, but it buys all of its water from the Red Lion Municipal Authority. That water comes mainly from the Cabin Creek reservoir, with Beaver Creek added when demand is high and a Susquehanna River pump station held for drought. The authority has also published a service line inventory, so you can look up what your line is made of.
After a main break on West Broad Street on January 16, 2026, the authority's advice was to open an outside faucet for a few seconds once water came back, to clear air and dirt from the line. During hydrant flushing in May 2026, the borough said to make sure the water wasn't discolored before doing laundry. Both are good habits for a water heater too: clear the cold lines first, so dirt doesn't get pulled into the tank.
Two gas companies, older houses
About 57% of Dallastown homes heat with gas and 36% with electricity. UGI lists Dallastown Borough in its York County region, and Columbia Gas of Pennsylvania lists it in its service area too, so your bill tells you which company is yours. That matters for outages and leaks. In January 2019, a Columbia Gas outage left many Dallastown customers without gas overnight while service was restored.
When gas comes back after an outage, a gas water heater has to be relit. If the pilot won't stay lit afterward, the thermocouple or gas valve may have been on its way out. With a median build year of 1958 and a third of homes from before 1940, plenty of gas heaters here still vent into an old chimney, so a replacement should include a look at the vent too.
Safe steps for Dallastown homes
- Leaking? Close the cold water valve on top of the tank.
- Turn off the gas valve or the breaker for the heater.
- Gas smell? UGI and Columbia Gas both list Dallastown. If you smell gas, leave the house, then call UGI at 800-276-2722, Columbia Gas at 888-460-4332, or 911 from outside.
