Leak Risks in Marin County
Hard Water Corrosion
Water in Marin has more minerals than most Bay Area sources. Over time, this causes buildup and corrosion inside your pipes and on fixture connections, weakening them and leading to leaks — often hidden inside walls or under slabs.

Aging Eichler Pipe Systems
Many Eichler homes in Marin still have their original 60-year-old copper piping embedded in the concrete floor. These systems are well past their expected lifespan and are a common source of slab leaks — one of the most damaging and expensive types of water damage.

Insurance Requirements
State Farm and other major insurers are now requiring smart leak detection devices in California homes, particularly in Marin. Failure to install one when required could result in loss of coverage — a risk far greater than the cost of installation.

Tips for Marin Homeowners
- If State Farm or another insurer has flagged your policy, don’t wait. Installations typically take half a day — we can often get to you within a week of your call.
- The biggest source of costly hidden leaks in Marin is aging boiler connections and corroded pipe joints. Annual maintenance catches these before they flood your mechanical room.
- Before installing a leak device, it’s worth pressure-testing your in-slab pipes. A device will catch supply line leaks — but a slab leak is a different problem requiring a different solution.

Why does my insurance require a leak detection device?
Water damage is a massive expense for insurers. These devices prevent catastrophic damage by automatically shutting off water at the first sign of a leak. State Farm is leading this requirement in California, and other carriers are following.
What happens if I don’t install one when required?
If required by your policy and you don’t comply, your insurer can non-renew your policy. Check with your insurance agent about their specific requirements and timeline for your home.
Is it worth installing even if my insurer doesn’t require it?
Yes. Given Marin’s hard water and the number of aging Eichler homes in the area, the risk of a significant leak is real. An automatic shutoff provides essential peace of mind — especially when you travel.
How much does it cost and how long does installation take?
Installation typically runs $1,500–$2,000 including the device and labor. The installation itself takes half a day to a full day depending on your water line configuration.
