Plumbing Leak Sensor Installation in Arizona
Installation of point leak sensors at the spots most likely to leak — under sinks, behind the water heater, at the washer and dishwasher — that alert your phone the moment they detect water, before a slow leak becomes a big one.

Most home water damage doesn't start with a dramatic burst — it starts with a slow drip under a sink, behind a water heater, or at a washing-machine hose that no one sees for days. Point leak sensors are small, inexpensive devices placed exactly where leaks begin, and they sound an alarm and alert your phone the instant they detect water on the floor. For a fraction of the cost of a whole-home system, they turn the most common slow leaks into an early warning instead of a rotted cabinet or a soaked Arizona ceiling below.
We place sensors at the spots that statistically leak first — under kitchen and bathroom sinks, at the base of the water heater, behind the washing machine, at the dishwasher and refrigerator lines, and near any sump or basement fixture. The sensors are wireless and battery-powered, so there's no drilling or wiring, and they tie into the same app ecosystem as a smart shutoff valve. A leak at any monitored point pushes an immediate alert with the location, so you know it's the water heater and not the dishwasher before you're even home across Arizona.
Leak sensors are the affordable entry point to water-damage protection, and they pair naturally with an automatic shutoff valve — the sensor detects, and the valve closes the main. On their own they give you the minutes that matter, letting you shut a fixture stop or the main before a slow leak becomes a claim. We place them where your home is actually vulnerable, set up the alerts, and show you how to respond, so a drip behind the Arizona water heater becomes a phone notification instead of a surprise flood.
Symptoms that call for leak sensor installation
Appliances that leak unattended
Washers, dishwashers, and refrigerators leak at their supply lines with no one watching, often overnight. A sensor at each catches the drip the moment it starts in the Arizona home.
Dripping, stiff, or leaking faucet? Fixed at the cartridge.
A finished basement or living space below
A leak above a finished space rots and stains before it's found. Sensors at the fixtures above turn that hidden leak into an alert across Arizona.
A water heater near the end of its life
An aging tank often weeps at the base before it fails outright. A sensor there gives you warning to replace it before it floods the Arizona floor.
You want protection without a big project
Not every home needs a whole-house shutoff to start. Point sensors are a low-cost, no-wiring way to cover the leak-prone spots in a Arizona home today.
A second home or rental you don't visit daily
A property you're not in every day can leak for a week undetected. Sensors alert your phone remotely so you know the moment water shows up across Arizona.
What's behind it — and how we fix it
Supply-line and hose failures
Washer hoses, ice-maker lines, and braided sink supplies burst or weep without warning. A sensor at each catches the water immediately in the Arizona home.
Water heater seepage
A corroding tank often leaks slowly at the base for days before it fails. A sensor under it turns that early seep into a warning across Arizona.
Drain and P-trap leaks
A loose or corroded trap under a sink drips into the cabinet unseen. A sensor on the cabinet floor flags it before the Arizona base rots.
Sump and basement water
A sump that fails or a basement that seeps floods the lowest level quietly. A sensor near the pit alerts you before the water rises in the Arizona home.
Refrigerator and dishwasher lines
The lines behind and under kitchen appliances leak where they're hardest to see. Sensors there catch the drip early across the Arizona kitchen.

The leak sensor installation questions we hear most
Top questions homeowners searching for Leak Sensor Installation near me ask us:
What happens when a sensor detects water?
It sounds a local alarm and pushes an immediate alert to your phone with the location, so you know exactly which fixture is leaking. That warning gives you the minutes to shut the fixture stop or the main before a Arizona leak spreads.
Where should leak sensors go?
At the spots that leak first — under every sink, at the water heater base, behind the washer, at the dishwasher and fridge lines, and near any sump. We place them where your Arizona home is actually vulnerable and set up the alerts before we leave.
Can I add sensors to a system I already have?
Usually yes — the leading sensors tie into the same app ecosystems as smart shutoff valves and hubs. We match new sensors to your existing setup and place them where you still have gaps, serving ZIPs across Arizona.
How are they different from a smart shutoff valve?
Sensors detect water at a specific spot and alert you; a shutoff valve monitors the whole main and can close it automatically. Sensors are the affordable first step, and they pair with a valve so detection triggers an automatic shutoff across Arizona.
Do sensors need wiring or drilling?
No — they're wireless and battery-powered, so we simply place them at the leak-prone spots and pair them to the app. There's no drilling or electrical work, which makes them a fast, low-impact install in any Arizona home.
