Plumbing in Prairie Village homes

Prairie Village is an older suburb, and its plumbing shows it. According to the Census Bureau's American Community Survey (2020–2024 5-year estimates), the median home in Prairie Village was built in 1959. Of the city's 10,287 housing units, 57% were built before 1960 and 45% were built in the 1950s alone. Only 13% were built in 1990 or later.

What a 1950s house means for the plumbing

A house built in the 1950s has had 70 years to wear out whatever the original builder put in, and some of it is still there. These are the things worth knowing about in a home of that age. They're general to the era, not a claim about any one house; a camera or an inspection tells you what yours actually has.

• The sewer lateral. The pipe from your house to the public sewer is often original in homes this age, and it runs under yards with decades-old trees. Johnson County Wastewater says roots in the service lateral are a common reported issue, entering through small cracks and breaks from age and soil compaction. See sewer line repair and sewer camera inspection.
• Drain and supply piping. Older cast-iron drains and galvanized steel supply lines corrode from the inside. Low water pressure at several fixtures, rusty water and slow drains are the usual signs. See pipe repair.
• Water heater venting. When an older furnace is replaced with a high-efficiency model that vents out the side of the house, the gas water heater can be left alone on a chimney or flue sized for two appliances. "New venting" is on Prairie Village's permit list for a reason. See water heater replacement.
• Basements. Floor drains, sump pits and laundry drains in basements finished long after the house was built.

Your water: WaterOne, about 7.9 grains per gallon

Prairie Village is one of the 17 cities WaterOne lists in its service area. WaterOne's 2026 Water Quality Report (covering 2025) lists an average total hardness of 135 ppm, with a range of 110 to 157 ppm. Using WaterOne's own conversion (ppm ÷ 17.1), that's about 7.9 grains per gallon. That's the number to use when setting a water softener. Hard water leaves sediment in tank water heaters and scale in tankless heat exchangers, faucet aerators and showerheads. More in How hard is Johnson County water?

Permits: what Prairie Village requires

Prairie Village requires a building permit for water heaters, sump pumps, gas lines, repiping or moving a drain, backwater valves and new venting. Putting a fixture back in the same location doesn't need one. To pull a plumbing permit in Prairie Village, a contractor needs both a Johnson County Contractor License (class DP) and a Prairie Village contractor license. If the work is an emergency, the city's code lets it proceed, with the permit application due by the next working business day.

The sewer line is yours

Johnson County Wastewater lists Prairie Village in its service area. JCW says the pipe that connects your home to its public sewer main is private property: the homeowner is responsible for maintaining, repairing and replacing it, including the connection at the main. Repairing a damaged or collapsed lateral requires a JCW Sewer Repair Permit, which is free. JCW also prohibits connecting a sump pump to the sanitary sewer. Read Tree roots and old sewer laterals.
