Plumber in Cotati, CA
Cotati is right next door to our Rohnert Park shop, so getting a truck out to the hexagonal plaza or the streets off East Cotati Avenue takes us almost no time. CNTRline Plumbing has served this town since 2017. The old six-sided La Plaza is one of only two like it in the country, and we know the neighborhoods around it well.

Plumbing in Cotati
Homes near downtown Cotati date back further than most people expect, with cottages sitting alongside the tract houses that filled in during the 1960s and 70s. A couple of the city supply wells run high on iron and manganese, so staining and buildup inside pipes and heaters is a common complaint. Older drain lines under these smaller lots clog more than newer ones do.
Iron and manganese in some of the local groundwater rusts out fixtures and clogs faucets, so faucet and fixture repair keeps us busy in Cotati.
Neighborhoods we cover: La Plaza, Downtown Cotati, Old Redwood Highway, East Cotati Avenue.
ZIP codes: 94931.
