McMaster Carr actually no longer ships to Canada. :cry:

Yeah, hi, I'm not taking credit.

Additionally, I've had at least ten people use this design perfectly well with a good quality ball-valve. I think the most time spent on the adjustment was somewhere in the neighborhood of five minutes. But hey, for anyone who wants to spend more than $25 on a valve, it's their money.

And hey Andy, if you would like, please step up and take the throne to the Kingdom of Negative-attitudes. It's all yours.

Alright people lets not get out of hand here keep it in the good books can we. the board is to special to be filling it with negative and crappy thoughts.

FOr the record I would not have a valve to throttle back a pump unless it is a pressure and still the only place to throttle a pump back is at the end of the line going out. there is to much pressure at the start of the pump and that is how seals are blown.

If you want to throttle the pump back I think some one already said about a T joint and have a another line run back to the sump or to a Refuguim. That will work too. Having a grill on a over flow pipe is going to cause alot of trouble a ways down the road.

I would have the full flow going to the main tank and you can always up grade the return line to a bigger pipe to get more volume then pressure .

HTH

Or may i misread the post any wyas keep us informed

The pump isn't being throttled back. One of the drains is being restricted to fascillitate with noise reduction in the system.
