Hi - I have some experience installing a large sprinkler system at my current house and am planning to install a system at my girlfriend's house soon. However, her house has unusually low water volume coming from the supply line (supply line looks to be 3/4" as opposed to 1-1.5". What is the best way to handle this? I plan to add more zones/fewer heads per zone, but am wondering if there are some best practices in terms of head type, system design, etc. that can help me? One specific question....if I opt to install main lines off the manifold that are 1/2" as opposed to 3/4" will this help mitigate the problem of low water volume? I am planning for very few pop up heads per zone and more drip zones than usual as these seem to handle low volume better. Any help would be greatly appreciated! Thanks!

I currently have an irrigation zone that uses 4 inch pop up valves. The zone is approximately 150 feet long and provides water to evergreens that have a height of 6 feet. The pop valves are providing a lack of water to the back side of the bushes. I would like to convert the pop valves to a drip system to enhance the watering of the plants and improve the efficient use of the water. Can this be done? If so, what do I need for the conversion? Currently, I have toro pop up sprinklers. Thanks
