Local Know-How

What We See in Mason Plumbing

A few things specific to Mason that affect your plumbing:

Greater Cincinnati Water Works Supply

Mason's water comes from Greater Cincinnati Water Works, which took over supply and began delivering softened water from its Miller Treatment Plant in 2005. It's softer than the old city water, but it still carries minerals that build up in water heaters over time. If scale is an issue, we can install a water softener.

City Sewer to the Reclamation Plant

Mason's wastewater flows to the city's Water Reclamation Plant on Mason-Morrow-Millgrove Road. The pipe from your house to the public sewer is the owner's to maintain — that's where roots and sags cause backups, and where a camera inspection pays off.

Growth-Era Homes

A lot of Mason housing went up during the city's growth of the 1990s and 2000s. Original heaters, valves, and supply lines in those homes are now at the age where proactive replacement makes sense.

Recent Work in Mason

Water pressure that's too high is a problem we fix often in Mason. When the pressure reducing valve on the main line wears out, pressure can climb or swing up and down: faucets bang shut, toilets run on their own, and supply lines and heaters take extra strain. We check the pressure with a gauge and replace the failed PRV, then set it to a safe level for the house.

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.
