Florissant is one of the largest municipalities in St. Louis County, with a housing stock primarily built between the 1950s and 1980s. This era of construction means most Florissant homes have copper or early PEX supply lines rather than galvanized, but many still have cast iron drain stacks and clay sewer laterals. Water heater service, drain cleaning, and pipe repair are the most common plumbing calls from Florissant homeowners.
Florissant connects to the MSD sewer system. Mid-century homes in Florissant typically have 3-inch cast iron drain stacks that may need replacement after 50–60 years of service. The city's relatively flat terrain means sewer laterals often have minimal slope, making them more susceptible to sediment accumulation.

"Cast iron drain stack in our 1968 split-level finally gave out — sewage was seeping through the basement floor. They replaced the entire stack with PVC from basement to roof vent in one day. Clean work and they hauled away all the old pipe."
"20-year-old water heater was leaking from the bottom. They replaced it with a high-efficiency model and added an expansion tank. Installation was done in about 3 hours, and they disposed of the old unit."
"Both toilets were running constantly. Plumber replaced the fill valves and flappers in both, and adjusted the float levels. Simple fix, fair price, and our water bill dropped noticeably the next month."
