Freddie and Matthew were very prompt, cleaned up all materials and did a great job installing our automatic water shut off. We would highly recommend Sweetwater plumbing!
Why install one
Why install an automatic water shut-off valve?
Water damage is one of the most common and costly homeowners insurance claims. Some homeowners insurance companies give a premium credit for an installed automatic shut-off device, so ask your agent what yours offers.
It also protects your home while you're away. Burst pipe at 3 a.m. in an empty house? The valve shuts off the water and you get a phone alert. Without one, the leak runs until someone notices.
How it works
A valve on your main line that watches for leaks.
An automatic shut-off valve is installed on the main water line where it enters the house. It watches how water is flowing. When it sees a pattern that looks like a leak, such as water running nonstop, it closes the main and sends an alert to your phone.
Many systems can also work with small leak sensors placed where leaks usually start: under sinks, behind the washing machine, next to the water heater and under the refrigerator. If a sensor gets wet, the valve shuts the water off.
Who it makes sense for
Who it helps most.
- Homes that sit empty: while you travel, or for a vacation or rental property
- Homes with a water heater inside the living space: a closet or attic water heater can do a lot of damage if it fails
- Older plumbing: galvanized or aging copper lines, or a home that has had leaks before
- Anyone who travels or owns a rental: you can check and shut off your water from your phone
How we install it
Installed right, and set up with you.
- We check your main line first: the size, the material and the condition of the existing shut-off
- You get options in writing: the valves that fit your home and how each would be installed, each with one flat-rate price, before any work begins
- We install and test it: we then show you how to use the app and how to turn the water back on
- We label your shut-offs: every shut-off we find gets labeled, so everyone in the house knows where the main is

Freddy worked his tail off without stopping. Had to dig 4 feet down to find leaking water pipe. Cleaned the bathroom professionally. Never knew he was there after cleaning up.

Common Questions
Frequently asked questions.
How does an automatic water shut-off valve know there is a leak?
It watches how water flows through your main line. Water that keeps running when it normally wouldn't, or a sudden large flow, looks like a leak, and the valve closes the main and alerts your phone. Leak sensors placed near appliances can trigger it too.
Will it shut off my water when I take a long shower or water the lawn?
Most systems learn your normal use and let you set schedules or a vacation mode, so everyday use doesn't trip them. We help you set it up during the installation.
Can an automatic shut-off valve help with my homeowners insurance?
Some homeowners insurance companies offer a premium credit for an installed automatic shut-off device. Ask your agent what yours offers.
Where is it installed?
On the main water line where it enters the house, usually near the existing main shut-off. We check the location and the condition of your main line before recommending a valve.
Does it work if the power or Wi-Fi goes out?
That depends on the model. We explain how the valve you choose behaves without power or Wi-Fi, so you know what to expect.
