Replacing Toro Hydraulic Controller: Conversion Kit or Electric Valve Upgrade

Toro Series 90 Custom II Hydraulic Controller Dead: Two Paths Forward

8-station hydraulic (tubes to valves). No new hydraulic controllers made. Options:

Option 1: Toro Hydraulic-to-Electric Conversion Kit

• 8-station module converts electric signals to hydraulic pressure.
• Keep existing hydraulic valves and tubing.
• Buy kit + new electric timer.
• Cost: Kit is pricey; hydraulic valves will still fail eventually.

Option 2: Replace Valves with Electric (Recommended)

• Install 24 VAC solenoid valves (Rain Bird, Hunter, Irritrol).
• Run 18 AWG direct-burial wire from new controller.
• Eliminate hydraulic tubing forever.
• Standard parts, easy future service.

Where to Buy

• Local Toro dealer
• Ewing Irrigation
• John Deere Landscape

Invest in electric valves now. Hydraulic is a dead end.
