1990s subdivisions and older homes on the mile roads
The median home in the township was built in 1995, and only about one in ten predates 1960. Close to 70 percent of homes are single-family detached houses, and about 6 percent are mobile homes. Most families own their homes, which means the person calling us usually owns the sump pit and the water heater too.
Newer houses tend to have copper or PEX supply lines and PVC drains. Those hold up well; the trouble comes from the equipment attached to them. A sump pump in a poured basement does its job for years and then sticks on a spring night. An irrigation backflow assembly freezes in October when nobody blew out the lines. A first replacement water heater sits in a tight corner where the original went.
The older rural homes are a different job. If your house is on a private well, low pressure can come from the pressure tank or switch, and hardness and iron depend on your well rather than a water report. Sewered parts of the township drain to the county's Macomb Interceptor Drain Drainage District. Public water didn't reach the township until the late 1970s, which is why the township says it has no lead service lines.

Township permits for backup sump pumps and sprinklers
The township's Building Department issues plumbing permits for lawn irrigation, fire sprinklers and backup sump pumps connected to public water. Public Works handles water connections and the second meter that irrigation uses. Behind both sits the township's cross-connection program, which protects the public water system from anything that could siphon back into it.
A water-powered backup sump pump is the example people miss. It runs on house water pressure, so it needs a backflow preventer, and the township treats it as permitted plumbing. A battery backup avoids that question. Our article on a sump pump that runs constantly helps you judge whether the primary pump needs help first.

Main water line repair
Public water only reached Washington Township in the late 1970s, so service lines are copper or plastic rather than lead, but deep lots mean long runs where a leak can surface far from the house.

How a visit works on a large lot or a private well property
Lots out here can run deep, and the parts a plumber needs may sit far from the driveway. When you call, tell us where the well head, the cleanout or the sprinkler valve box is, and whether the house runs on a private well or township water. We pass that along so the plumber you're connected with isn't hunting across the yard.
For a backup sump or sprinkler job, ask the plumber who will pull the township permit. On site they find the cause, tell you what fixing it involves and what affects the price, and wait for your yes. They finish by testing the repair and cleaning up.

Washington Township plumbing questions
Does Washington Township require a permit for a backup sump pump?
Yes, for a water-powered backup tied to public water. The Building Department lists backup sump pumps connected to public water among the work that needs a plumbing permit. A water-powered unit uses house water pressure to lift water out of the pit, which makes it a cross-connection that needs backflow protection. A battery backup has no connection to the water supply, so ask which type fits your basement when you call.
Who handles a new irrigation meter or water connection?
Public Works handles water connections and the second meter for lawn irrigation, and the Building Department issues the plumbing permit for the sprinkler system itself. Under Michigan rules, a testable backflow assembly has to be tested by someone with ASSE 5110 certification who is also a licensed master or journey plumber, or an apprentice under one.
Can a homeowner pull a plumbing permit in Washington Township?
Yes, for work on the single-family home they live in. Michigan law gives homeowners that option; everyone else needs a licensed plumbing contractor to pull it. The township's Building Department issues the permit and the inspection follows either way, whether the job is a water heater, a backup sump or a new sprinkler line.
