I didn't mean I wanted to buy a new stock tank, just the drain valve. I did find it on the Rubbermaid commercial site
http://www.rcpworksmarter.com/rcp/products/detail.jsp?categoryID=507&subcategoryID=555&rcpNum=5050-12 but they probably won't sell a single one to me. I will call the Skippy site tomorrow and see about getting one overnighted. Right now, we're attempting a glue job but it's a pretty long crack and I'm dubious. We will also take it down to the hardware store (home depot and lowe's) as well and see if there is something that will fit. The hard part I think will be finding one that is square on the outside or that will bit within the space allowed.
This is a pic of the outside with the original plug.
http://www.skippysstuff.com/biofil02.jpgI have the plants from the skippy sitting in the pond now, I doubt most of them will do well but they were too big anyway. I had taro and canna in there that were at least 5' tall. The roots had gone throughout the skippy, it was just a mass of roots. It was working really well though, the water has been clear as long as it was running. Even now, with all these plants laying into the pond, the water is clear. It's not an optimal situation though and I want to get the skippy online and the plants out of the pond as soon as I can.
Oh, the waterlilies that I got right before we left in June are all blooming, gorgeous. The fish are fine and the Roy the Koi seems happy with his Wakin friends.
It was the banana. Whoa! That thing took off like I can't believe. We took out 6 trunks that were a foot in diameter and there are still 5 that size and a few small ones. We dug down where the banana sprouts had pushed up into the drain and put some metal flashing against the wall behind the skippy. We're hoping that plus more vigilence will keep it back.
