For the past couple seasons Ive been using The Gigit winterizing valve (basically a one way valve that screws into the jet ports of the pool, you use low pressure compressed air to blow through the lines and then the valve shuts)
This works fine on the return side where I built a manifold to feed the compressed air through. However, my pump uses quick connect plumbing on the suction side, so I don't have an easy way to interface compressed air directly with the quick connect.
My question is - can I put a barb fitting on one of the pump drain plugs and blow compressed air through that? I would put the multiport valve into Closed position so the compressed air going through the drain plug port *should* feed back thru the suction line right to the pool. Does that sound correct?
