gpm and sprinklers
« on: June 13, 2021, 05:15:45 PM »
If the csv is sending 1-2 gpm (I have the csv1a)  to the pressure tank, and my sprinkler zones are using 15-20gpm depending on the zone-should I place the supply for the sprinklers before the csv?
Thank you
Randy

No!  The CSV only sends 1 gpm to the tank AFTER you turn off all sprinklers and faucets.

sorry for my confusion but how dose the csv know the sprinklers and faucets are turned off and no longer needs to run at 20gpm

It knows because when you shut off the sprinklers the pressure increases above the setting of the CSV. it then closes down to 1 gpm which has no place left to go except the tank.
