Converting Toro Hydraulic System to Electric: Valve Replacement vs. Conversion Kit

Upgrading from Toro Custom Eight Hydraulic to Electric Control

Your old Toro hydraulic controller (tubes to each valve) can be modernized without replacing the entire sprinkler system.

Option 1: Hydraulic-to-Electric Conversion Module (Toro)

• Keeps existing hydraulic valves.
• Module acts as electric-to-hydraulic interface.
• Requires new electric controller + conversion module (8-station).
• Cost: Moderate. Hydraulic valves will eventually fail.

Option 2: Replace Valves with Electric Models (Recommended)

• Install new 24 VAC solenoid valves (Rain Bird, Hunter, Irritrol).
• Run direct-burial 18 AWG multi-conductor wire from controller to valve box.
• Eliminates hydraulic tubing, fittings, and future leaks.
• Cost: Higher upfront, but lower long-term maintenance.

Why Option 2 Wins

Hydraulic valves are obsolete. Parts are scarce, tubing becomes brittle, and diaphragm replacements are difficult. Electric valves are standard, reliable, and universally supported.

Pro Tip

If valve boxes are accessible, swap valves now. Use waterproof wire connectors and leave extra wire coiled in each box for future repairs.
