Hey Guys I finally have somthing to post instead of just being a lurker! I just built a pond and it is filling up nicely, my question is this:

I have 4 field tile which run into the pond at about 3'-0" below the surface ( or what will be the surface)

I would like to keep the tile funtional as they drain my horse pastures and hay field.

I am trying to figure out a check valve system which would allow the tiles to flow the runoff onto the pond and not backflow the pond into the tiles.

Any ideas?

Thanks in advance for the help

Mike
