FAQ's

What is an isolation valve and what does it do?

An isolation valve allows you to turn off the water supply to specific zones or sections without affecting the entire system. Here's how it benefits your irrigation setup:

Zone Control: With an isolation valve installed at the beginning of each zone, you can independently control water flow. You can shut off water to a specific zone for maintenance, repairs, or address areas that don't need watering at a particular time.

Winterization: When winter approaches and you need to prepare your irrigation system for freezing temperatures, isolation valves become crucial. By shutting off the water supply to zones using these valves, you can easily drain the water and prevent pipes from bursting due to ice expansion.

Troubleshooting: If you suspect a leak or problem in a specific zone, an isolation valve allows you to isolate that zone and focus troubleshooting efforts without disrupting the entire system. This saves time and water while you pinpoint the issue.
