ABSTRACT:
A method and apparatus is described which makes it relatively easy for a swimming pool owner to economically and efficiently winterize a swimming pool. A one-way valve is initially connected between the swimming pool and the recirculating water return line. The valve allows water to flow out of the return line but not in the opposite direction. A sealing plate is then placed over the intake throat of to the skimmer. It is then possible to purge the return line by blowing it out from the pump end. The skimmer intake line can similarly be purged by blowing it out from the skimmer end.
