What to use

I have a "home made" inground sprinker system. I pump water from a
backyard pond using a 1hp Wayne pump. The lines a one inch poly pipe.
I have 3 zones. Currently I manually open and close the valves. I want
to change this to an automatic system controlled by a timer. What do
you recommend for valves and a timer

If the system is operating with 'just enough' pressure, adding zone valves can subtract enough pressure to render the system non-functional. Pond water is assumed to be 'dirty' with valve clogging particles. A good strainer can protect valves, or you can spend extra for 'dirty water' valves like Rainbird PESB valves.
