Renters
You can't cut into a landlord's plumbing, and you shouldn't want to — but a leak in a rental still means your belongings, your deposit, and your time dealing with the fallout. Here's what actually works without permission or permanent installation.
Whole-home shutoff valves and inline monitors both need someone cutting into the main supply line — a modification no landlord signs off on, and one that leaves the device behind when you move anyway. What actually works for a rental is standalone and battery-powered: set it on the floor, done.
Connects straight to WiFi and that's it — nothing extra to unplug and repack the day your lease ends.
If it needs an electrician or a dedicated outlet, skip it. Battery sensors go anywhere and pack up with everything else.
Phone notifications can be missed. A sensor with a genuinely loud onboard alarm (100dB or higher) still alerts you even if your phone is on silent or dead.
If your unit has its own water meter accessible to you, a strap-on monitor like Flume 2 requires no plumbing modification and can be removed entirely when you leave — see our smart water meter guide.
Prioritize spots where a leak damages your belongings or your deposit fastest: under the kitchen sink, behind the washing machine if you have in-unit laundry, near the water heater if it's inside your unit, and under the bathroom sink and toilet. A typical apartment needs 3 to 5 sensors for meaningful coverage — far less than a full house.
