What shapes water heater trouble in Mason
Cincinnati water, moderately hard
All water in Mason comes from Greater Cincinnati Water Works, which also bills Mason households for sewer, trash and stormwater on one monthly statement. GCWW draws from the Ohio River at its Richard Miller plant and from 13 wells at its Charles M. Bolton plant. Miller water averages 126 mg/L, about 7 grains per gallon, and Bolton water 140 mg/L, about 8.
That is moderately hard, so a tank slowly builds sediment. On an electric heater it settles over the lower element. A flush every year or so helps. For a water emergency, GCWW answers 513.591.7700, option 3, around the clock.
Newer homes, lots of electric
The median Mason home was built in 1996, about 40% date from 2000 or later, and about 18% are attached homes like townhouses and condos. About 60% of homes heat with gas and 37% with electricity, so electric water heaters are common here. If an electric tank runs out of hot water fast, a burned-out element or thermostat is often the cause, and both can usually be replaced without a new tank.
In a townhouse, a leaking tank can reach a neighbor's unit quickly. Shut the cold supply valve above the heater as soon as you see water.
Look up your service line
GCWW treats its water for corrosion control and says there is no lead in the water when it leaves its plants. It offers free lead testing and has an online lookup map showing where lead service lines are, at lead.myGCWW.org.
$50 county permits, weekly large item pickup
The Warren County Health District's plumbing inspectors review and inspect residential plumbing work across the county, and they help homeowners who do their own plumbing. Its fee list includes a water heater only permit for $50, and fees double if work is done before the application is filed.
Mason contracts with Rumpke for trash. You can set out one large item a week if you call Mason Utility Customer Service at 513.229.8533 at least 48 hours ahead. Ask whether an old tank qualifies, or have the plumber haul it away.
Safe steps for Mason 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? Leave the house, then call 911 and Duke Energy at 800.634.4300 from outside. The city lists Duke Energy for electricity and natural gas.
