ABSTRACT:
An irrigation sprinkler of the type having an inlet control valve is provided with a removable valve seat formed integrally with an inlet filter screen. The valve seat is positioned to engage a valve head to normally prevent water inflow to a sprinkler case, whereas the filter screen prevents entry of small rocks and other particulate debris into the sprinkler case when the inlet control valve is open. The valve seat is removable from the top of the sprinkler case, without requiring disconnection of the case from a water supply line, to permit flushing of collected debris or to permit replacement of a damaged valve seat.
