I just purchased an old home which seems to have a 3 sprinkler head system installed. The valve system appears to be broken and I cannot seem to shut the system off when the water line is turned on...The valve looks similar to the Rainbird ASVF-series, the one I have does not have any markings on it that I can find and it seems to be alot older of a model if so. Also the sprinkler heads do say rain bird... Anyway , please bear with me if Im not making too much sense. The sprinkler heads also see...
