home and garden indoor environmental qualityHow long do irrigation valves last?
Similarly, it is asked, how much does it cost to replace a sprinkler valve?
The average cost to repair your sprinkler system is $75 to $250, with most homeowners paying $212. Most sprinkler repairs involve replacing sprinkler heads at $5 to $20 per head, or replacing valves at $20 to $40 per valve, not including the cost of labor of about $75 an hour by a professional plumber.
Then, what causes a sprinkler valve to stay open?
Air Trapped in the Valve: A small bubble of air becomes trapped in the tiny water ports of the valve, this stops the water from flowing through the port. Since the water flowing through the port is what holds the valve diaphragm closed, the valve stays open.
Each valve is responsible for one area, or zone, of the lawn irrigation system. When utilizing automatic valves, wires run from the irrigation controller, or timer, to each of the valves. A solenoid on the valve receives electric signals from the main controller. Inside the valve is a diaphragm, or rubber plug.
