Hi. I need help. I am in process of installing a sprinkler system at my house. The incoming city water pressure is 60psi. The main line is 3/4" copper but as the house is more than 50 years old, the pipe should have sediment build up. Doing a GPM test with 5 gallon bucket is giving me around 6.5gpm reading. The reading is from the first faucet on a new 3/4" copper line right after the meter. What can I do to improve the GPM to make it around 8-10 GPM at a minimum? Planning to have Hunter pgp ultra heads with 4 in each zone, a total of 10 zones. Thanks
