we just built an 8 acre pond and they gave us the wrong part for the drain pipe.(part that shuts the water off) We just got the right part, but not sure how this goes together. Hoping someone can lead me to a diagram! We ordered from Pond Dam Co. Its a butterfly valve kit, 2 van stone flanges and a bolt set. I went to the website and can't find any help there. Husband left to go get neighbor to help figure it out and try to get it on before dark. Any help appreciated! Will post pictures soon..we are so excited!
