any suggestions?

There are two types of sprinkler valves.... the selinoid type and the electric valve type...... I suppose the one you have is the electric valve type, when you hit the switch it starts to open slowly like you're turning a valve. you need the selinoid type.... when you hit the switch it pops open and lets the air out all at once. If you do have a selinoid valve then you just don't have enough pressure. |
