Leaky zone
Zone 4 on my system seems to have less pressure. Also, when zone 4 is on, zone 3 leaks from the heads and seems to create a pool of water. When zone 4 shuts off, the leaking from the zone 3 heads stops right away. Zone 4 is further than zone 3 from the manifold, therefore the water for zone 4 goes past the 2 heads for zone 3 underground. The valve on zone 3 is new. Could there be a split in the poly pipe of zone 4. If so, why would it turn on zone 3 a little bit? Or, could zone 4 need a new valve? Those seem to be my only options. Any thoughts?
