Review on 🚰 Zurn RK1 720AB Wilkins Pressure Breaker" - "Zurn RK1 720AB Wilkins Pressure Breaker Valve by Daniel Taylor

Bought during a week of severe freezes in Texas. The price went from $20 to $27. Installation was easy. However, water will still flow when the sprinkler is on. Disassembled, greased the rubber seal and reinstalled. No luck, same result. There is no leakage as long as the sprinkler is not turned on. Any ideas? The rating can be changed after the leak is repaired or repaired.
