Suspect that your skimmer line may be clogged with acorns, sticks, leaves or other debris? Attach the Drain King to a garden hose, insert into the pipe coming into the filter pump, and turn on the hose. The drain king expands to fit the pipe (up to 3" diameter), placing the line under pressure. The Drain King is a useful "water hammer" in any pool owners toolbox.
Use Drain King to unclog kitchen skinks, bathroom sinks, bath tubs, heating / AC drain lines and floor drains.
