Plumbing in Lafayette: what locals should know

Freeze risk
In Lafayette, pipe freezing is a moderate-to-high risk during the coldest months. Make sure you know where your main water shutoff valve is — quick action when a pipe bursts can save thousands in damage.

Local tip
Many Lafayette homes built before 1970 have galvanized steel pipes that corrode from the inside out. If your water pressure has been steadily dropping or you see rusty water, a whole-house repipe is likely needed.
