Affton is an unincorporated community in south St. Louis County, one of the most populated CDPs in the St. Louis metro area. The housing stock spans 1940s brick bungalows to 1970s ranch homes, with plumbing infrastructure that varies by era — older sections near Gravois Road have galvanized supply pipes and cast iron drains, while later construction has copper and PVC. Affton's central location and diverse housing make it one of the busiest service areas for plumbers in south county.
Affton is served by the MSD system as an unincorporated area of St. Louis County. The mix of construction eras means plumbing materials vary block by block. Older sections near Gravois and Mackenzie have clay sewer laterals, while areas developed in the 1960s–1970s may have early PVC.

"1952 brick bungalow with original galvanized everything. They repiped the entire house with PEX and replaced the main shutoff valve. Water pressure went from a trickle to full blast. Transformative."
"Both toilets running and the kitchen faucet dripping. They fixed both toilets with new fill valves and replaced the kitchen faucet. Quick, affordable visit that knocked out three problems at once."
"Sewer backed up into the basement utility sink. Plumber cleared the line and ran a camera — found root intrusion about 30 feet out. Scheduled a trenchless liner to fix it permanently."
