Anyone can install Guardian out of the box, but first, it's important to make sure Guardian is compatible with your plumbing.


Since Guardian installs on top of your existing valve, it will need enough space around it to accommodate Guardian:

Make sure any elbows, T's, and other pipe fittings are at least 4.5" away from the center of the valve.

4.5" of clearance is required above the pipe for the Valve Controller's body.

The water main should be at least 2" from the wall.

If you don't have enough space around your water main for Guardian, request a service call and we can take care of the rest.


Make sure your water main valve meets the following requirements:

Plumbing should be between 1/2" and 1-1/4" in size.

Guardian works with Copper, PVC, PEX, and most other plumbing materials.

The water main should be a standard metal 1/4-turn ball valve.

If you have the wrong valve type or size, request a service call and we can fix the issue.


To use Guardian without any unexpected hiccups, make sure you meet the requirements below:

Usable Wi-Fi connectivity near your water main valve (for initial setup and remote notifications/control). (2.4GHZ)

The Guardian Valve Controller should only be used indoors.

If your water main is in a poor location, request a service call and we can relocate it for you.
