Hydra Rain HR-6100 Noisy Valve Location and Replacement

HR-6100 (5 zones): one valve high-pitched noise when active. How to find it? Are valves different per zone? Where to buy?

Finding Noisy Valve

• Listen at each valve box during operation
• If only audible through pipes: need wire/valve locator
• Locator: connects to controller wires, traces to solenoid (rent or hire)

Valve Consistency

Each zone has SEPARATE valve. Usually same model, but can differ.

Replacement Source

Any irrigation supply store. Bring old valve or model number.
