Winterizing and Test Plugs
A winter plug is basically a cork shaped piece of rubber with a threaded eyeball fitting on top of it. It is primarily used on above-ground or in-ground swimming pools. Its main purpose is to prevent the water in your pool from running out when the pool's filter and plumbing systems are removed.
