Smile Sprinkler System - Low water volume at the source

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!

Find a new source. no, just picken. You may have to use more drip than spray. Maybe use misters, or small sprayheads.I wouldnt use small pipe. I would run 1.25" or 1.5" main lines. If the source ever changes the piping will be large enough to acomadate larger zones or more sprayheads.
