A smart leak detector sits on your main water line and watches for drips. If a pipe bursts while you are at work, the system kills the water automatically. It usually takes a plumber about an hour to install, so we suggest bundling this with other repairs to save on the service call fee.
Winter is the busiest time for plumbers because of frozen pipes, so try to book this in the spring or fall. Get at least two quotes for the labor. Some units are DIY, but a pro ensures the shut-off valve actually works when it matters.
The intro window is a firm deadline, not a gift. If you still have a balance after 18 months, the standard interest rate applies to whatever is left, which makes the safety system much more expensive.
