Abstract
An automatic flushing system for poultry watering systems is provided which includes a bypass of the upstream pressure regulator, self sealing caps for the stand pipes and a readily disassembleable automatic flush valve at the end of the supply line. A shut-off valve in the bypass is provided which is actuatable manually or automatically in response to a timer, environmental sensor or water condition sensor. The automatic flush valve opens in response to a predetermined pressure level and connects the supply line to a drain hose. The automatic flush valve can include an end cap which is removable from the flush valve and which facilitates cleaning of the valve and supply line. The self sealing caps prevent leakage out of the standpipes and are especially formed to prevent blow-outs of the seal. Where multiple pressure regulators are used in the supply line, additional automatic flush valves can be positioned in a bypass line around those regulators. The flush valve is readily disassembleable by use of a J-slot and post connection to provide access to the internal valve components for repair and maintenance.
