Over the years, I have installed several for my customers. You wonder what is a seasonal spigot? When houses/ condos/ townhouses are built, the builder or plumber picks the location of the outside spigots. Later, the location can become a PITA to use. As an example, had a customer (80+ years old) who had a deck full of flowering plants, that she was going to have to give up because she couldn't go down stairs, and around the deck to reach the spigot several times a day. She didn't want to leave water pressure on garden hose 24/7 either for fear of it bursting. So I hooked her up a seasonal spigot. I used 1/2" PVC, with a boiler drain, and a connector that allowed me to connect spigot to PVC using a washing machine hose. This way, water could be on from last freeze in spring to first freeze in late fall.
