Tips on washdown pump install?

[Marin]

Real smart, saltwater does not smell nice after parking in the pump/hose for even a few days.
Someone invariably grabs it to wash their hands and gets the rotten egg treatment!

It's smart if you do it in a smart way. We leave the seacock on the anchor washdown pump closed unless we're going to use the pump. So when we energize the pump for a second to move the impeller to a different parking spot it's not pulling any water in.
