Troubleshoot zone 3 not getting enough water pressure: looked for a leak but found none. Found 2 spray heads buried under lawn, however pressure was still very low. Determined that the shut-off valve on the water meter was only half open (or less); once I fully opened it, full water pressure was restored to system! Adjusted all heads on zone 3. Also, I reviewed customer’s program on his B-hyve app on his phone, and found that zone 3 was only set for 2 minutes, so I changed it to 20 minutes, as requested.
