Toro 100p1.5 Diaphragm Assembly 1-1/2 in Irrigation

Product Description

The TORO 100p1.5 is a diaphragm assembly designed for use in 1-1/2 inch irrigation control valves. This assembly serves as the internal flow-control component within globe and angle-style electric valves, regulating water passage through the valve body when the solenoid cycles open or closed. The diaphragm is a wear item in any solenoid valve system and is a common replacement part during routine valve service. Licensed irrigation technicians and plumbers install this assembly when a valve fails to close, leaks past the seat, or shows reduced flow performance caused by a deteriorated diaphragm.

This diaphragm assembly is suited for residential and light commercial irrigation systems where 1-1/2 inch electric valves control zone flow. It fits globe-style and angle-style valve bodies in the Irritrol 100P series. Install scenarios include zone valve rebuilds on in-ground sprinkler systems, drip irrigation mainlines, and landscape water feature controls. The assembly is a non-regulated type, meaning it does not incorporate a built-in pressure-regulating function.

Key Features

• 1-1/2 inch valve size fits standard globe and angle valve bodies in the Irritrol 100P series
• Non-regulated diaphragm design for straightforward zone-valve applications
• OEM-style replacement restores proper valve seating and flow shutoff
• Designed as a direct service component, simplifying valve rebuild without full valve replacement

Compatibility

Designed as an OEM-style replacement diaphragm assembly for 1-1/2 inch Irritrol 100P series globe and angle electric irrigation valves.

Installation Notes

Irrigation technicians and licensed plumbers typically perform diaphragm assembly replacements. Shut off the water supply to the valve and relieve system pressure before disassembling the valve bonnet. Follow local plumbing codes and the valve manufacturer service guidelines when reassembling. Inspect the valve seat and solenoid for additional wear while the bonnet is removed.
