it is summer time agian. i want to water the lawn. here is our home manual for openning the valve.
1. close the bleed orifice at inside valve
2. preset vacuum breaker
3. close hose bibb
4. attach garden hose
5. open valve inside home

when i did the last step, even i tightly closed the bleed orifice at the inside valve, the water was still leaking from the bleed orifice. do you know how to prevent water from leaking?

thanks.
