My long-term plans for AP at my place include having a decent sized system in my living room, since it has the only south-facing window in my house. Living this far north, the only way I can run a system all year is to have it indoors. My wife is on board with most of my plans, "as long as it looks good". I know a few finishing carpenters, so I think asthetics will be fine; however, visiting with guests and watching TV in the livingroom are 2 things we do a lot of, and I'm concerned that noise may be a factor.
I've done a lot of work with aquariums and sumps, and know how to make them almost silent (durso and herbie drains), but I'm wondering if that'll be possible with a flood and drain system. In the aquarium, then top tank has a constant level, so there's no sound of the siphon breaking, and the return can be placed under water, as the return chamber of the sump tank is typically kept at a constant level using baffles.

Does anyone have any experience keeping an AP system in their livingroom (or any other highly inhabitted room in the house), and are there ways to mitigate the sound of the drain (I'm guessing durso will work the same) and siphon break (this one has me a bit stumped).

Thanks!
