Water Heater Repair in Ledyard, CT
Two of every three Ledyard homes heat with oil, and only about 3% use gas. The reservoirs that supply Groton's water sit partly in Ledyard. If your water heater has quit, is leaking or making noise, call and get a plumber out.
What shapes water heater trouble in Ledyard
Oil first, electric second
About 65% of Ledyard homes heat with oil and 21% with electricity. Gas is rare. If your boiler makes your hot water, a no-hot-water problem can start on the boiler side. If you have a stand-alone electric heater, the elements and thermostats are the usual failures.
Built in the 1970s, now on later heaters
The median Ledyard home was built in 1972, and about 72% were built before 1980. A house that age has likely been through several water heaters already. Older shutoff valves and connectors are worth replacing when the heater is.
Groton's reservoirs start here
Groton Utilities says its upper reservoir system, Billings Avery Pond, Morgan Reservoir and Ledyard Reservoir, sits in Ledyard. The Montville WPCA notes that water from the Groton reservoirs is pumped through the Gales Ferry section of Ledyard and under the Thames River to Montville.
