Front Zone Low Pressure: Waterproof Wire Connections and Leak Testing

New controller didn't fix: front zone low pressure/drizzle, back works. Wiring/valve swap no change. Once in blue moon front works. Asks how to check waterproof connections and test for leak without running all day.

Waterproof Connectors

"It's actually the wire connectors that need to be waterproof. If you remove one from the valve wires, it should have either a silicon or grease substance in it if it is waterproof."

Leak Finding

"As far as locating a leak, you just have to turn it on and follow the line until you see something." No magic conservative test—water must run to surface.

Front zone issue likely a mainline leak between valve and heads, or a valve not opening fully. Waterproof connectors prevent solenoid shorts but don't affect pressure directly.
