Let me ask for a clarification: You just added automatic valves. (right?)
Everything else worked fine before the new valves?

om...
I had automatic lawn sprinklers installed and have had low pressure
from the sprinklers since then. Th line pressure is MORE than what is
expected so it must have something to do with this new set-up. No new
sprinklers were added so this can't be the answer. I now have brown
spots where the sprinklers don't reach. Was this a bad installation
job or any ideas? Thanks.
