Hi! I am in need of some advice. I’ve previously posted that I have a valve box that has been swallowed by roots. Everything is operational but there is a slow leak from the main at this valve box. I am unable to move the valve box until late this year or next year. I am looking for a part time fix and thought that I could add a valve at the main line that will turn on when the sprinklers run and off when it stops. I will have to manually align these symptoms but thought this would drastically reduce the water usage/ waste. The question that I have, am I able to add a 1 inch valve with a digital battery powered timer to the arrow shown below? What other options do I have?
