I use the valve at the bottom of the primary drain set up and it works great. No noise at all. If you go this route make sure you use a gate valve and not a ball valve as the gate valve is easier to adjust. I have the ball valve on myn and I have to adjust it about once a week, basiclly every time I do a water change. But like Meister said make sure you have a back up drain plumbed higher than the gate valved like incase of blockage.
