NEW Tank Build !!!

[The Grizz]

I found that the 1" durso was way to loud so I went with 1 1/2" and made all the difference in the world.

I guess I need to put a balancing valve in? If so can this go near the sump or has to go up by the tank?

[lastlight]

I always put the gate valve at the pipe's end before it enters the sump chamber. it needs to control the sihpon properly and because the water throughout the pipe is pulling downwards I think it has to be at the sump.

Ok so what I have learned is this

drain 1 Durso style with balancing gate valve at sump?
drain 2 = open acts as overflow

You balance drain 1 until it stops sucking in air and drain 2 takes the excess water?

[lastlight]

you don't need dursos really. the full siphon can just be thru bulkhead. i tune the flow so it just barely trickles into the secondary standpipe. You make the standpipe / emergency drain taller to raise the water level in the overflow box and make it as quiet as possible.

so the emergency also allows you to balance the height of the water in the tank?
