I have added a 32mm gate valve below the ball valve I already had on my DT to sump return. Gate vales are much easier to balance and fine tune. I can now shut of the water to the sump using the ball valve above and use the gate valve to fine tune the water level in my weir. Just a small mod but a worthwhile one for anybody having difficulty getting the ideal height of water to the overflow in their weir.

I've thought about doing this a few times... looks like it works!

Man you can adjust these like nothing else! Takes about 30 turns to close it! LOL!

But you have no need to close it if you have a ball valve above as I and many more have. Ball valve = on and off, gate valve - fine adjustment. :)

YES! My point was that you can fine tune like crazy! Like a ball valve takes one turn and the gate takes many because you can fine tune it so well. I added three to mine!

Thanks for the awesome idea! Glad I saw this post just in time as I was in the middle of plumbing my new tank and had an extra ball valve sitting around.
