I saw some duck pond plans on here the other day. It was with a 500 gallon rubbermaid brand tub and attached was pvc pipe to drain the water. Does anyone know where this can be found?? thanks!
All the Rubbermaid stock tanks come with a 1-1/4" threaded drain. In this picture, it is a small tank but I also have two 300 gallons ones used as filters for my pond and duckling brooder. They have the same drain setup.
All you need is
1-1/4" male threaded adapter
length of 1-1/4" PVC pipe
In my picture, you can also see a 1-1/4" ball valve. I turn the valve to drain the water.
All these stock tank drains are on the side, rather than the bottom, so you cannot drain every drop of water.
