Abstract
A breather cap assembly is provided which is configured to be connected to a stand-tube used in a watering system. When the watering system is in normal operation, the breather cap assembly is configured to allow for air to flow between the outside the assembly and the stand-tube. The breather cap assembly also provides for structure which acts as a baffle to minimize the introduction of foreign material from outside the breather cap assembly into the stand-tube. When the watering system is in flushing operation, the breather cap assembly is configured to seal off the stand-tube in order to minimize the possibility of water leaving the stand-tube. The breather cap assembly further also provides for structure which acts as a baffle to collect and retain a majority of any water that does leave the stand-tube during a flushing operation.
