Replacing an Old Richdel Single-Station Outdoor Controller

No Direct Replacement for 15-Year-Old Richdel Single-Station Timer

A homeowner's 15-year-old Richdel single-station outdoor controller sticks at 4 PM (clock runs). No replacement found at Home Depot, Lowe's, or online.

Repair Unlikely

Parts for controllers this old are virtually unavailable. The mechanism (likely a motor-driven cam) is worn.

Solution: Upgrade to a Small Multi-Station Controller

The smallest readily available controllers are 3- or 4-station models (e.g., Rain Bird ESP-3, ESP-4). They fit in the same outdoor enclosure, cost little more, and offer future expansion.

Where to Buy

• Irrigation supply stores (Ewing, Horizon, John Deere Landscapes, SiteOne)
• Online irrigation retailers

Don't waste time hunting for a single-station unit—upgrade and be done.
