Full Siphon Standpipe

Today I assembled the full siphon standpipe. As you can see from yesterdays pictures I did not have the union or ball valves as part of the dry fit. All the fitting on this channel are now cemented into place.  I think I'm only going to use union valves for the open channel and emergency standpipes in order to breakdown for cleaning. I cannot think of any reason why I would need ball valves on these channels. Probably next week sometime I will finish the overflow plumbing. 

Drilling.

Today I drilled the tank and cut and dry fit most of the plumbing. Also painted the back of the tank, pics of that will be up tomorrow. Drilling of the bulkhead holes went pretty painlessly. The first hole was the easiest and fasted by far. By the third hole the bit was getting a little worn down so it took slightly longer.
