A few things specific to Maineville that affect your pipes and fixtures:
Maineville is served by Warren County Water & Sewer's Richard Renneker plant, which began delivering membrane-softened water in late 2022. The county reports an average hardness of about 140 mg/L (8 grains).
When the county started softening, it told customers they could bypass or recalibrate home softeners. We test hardness on site and help you set yours right — or decide you don't need it.
In newer subdivisions, original water heaters, fill valves, and supply lines tend to wear out around the same time. We'll tell you honestly what needs replacing now.
Softened water isn't the same as filtered water, and plenty of Maineville homeowners call us about what's still in it: a chlorine taste or smell, or bits of sediment that show up in faucet aerators and appliance screens. We install the filter housings, add a shutoff on each side so the cartridges can be changed without draining the house, and tell you how often to swap them. If a housing is cracked or leaking, we replace it.

We also serve nearby Loveland, South Lebanon, Mason, and Lebanon.

During our posted hours — Mon–Fri 8am–7pm and Sat 9am–1pm — sewage backups, burst pipes, and leaking tanks in Maineville get priority scheduling, and same-day replacements are often available. While you wait: if a pipe is leaking, shut off your main water valve (usually where the water line enters the house, often in the basement near the meter) by turning it clockwise. If the tank is leaking, close the cold-water valve on top of it and turn off its gas supply or breaker.
