Installing a new irrigation system .

Hi, we’ve recently had a lot of work done on our house and garden. However the builder has messed up (to be polite) the whole irrigation system. I need someone with experience to lay out a new system and connect it to the water supply. It’s quite a big system ( but not huge). Maybe about 160 meters zig zagging across the garden. We did have it on a timer on a tap with double connection (A & B) that came on every day for 30 mins each side. Need someone fairly urgently.

Cheers
