Plumb it with a standard drain, then up size it to 2" and put in a ball valve. After the ball valve use pex to take it where you want it. 2" is highly unlikely to get clogged by anything from the ducks.I am just trying to avoid extra expense, the tub doesn't have any drain right now, just a big View attachment 2317348hole where the drain pipe was attached. If I put it up on blocks I could reach the drain from the outside and pull the plug without putting my hands in ducky water. Running it to water a garden would mean I would have to put it near the garden. Close to where it is is a creek that would be fine to have some duck water. Maybe I can get some inexpensive PVC to fit this hole, then I could use a valve. Then I have to buy more stuff. I have time to look around the RE-store and see what I can fix up.
