I‘m designing my tank build as we speak and have started to consider doing dual corner overflows instead of a center overflow. Trouble is I only have two drain pipes (plumbed down to my garage). Would it be crazy to join the full siphon and emergency drain pipes from each overflow together so that each overflow combines into a central main drain pipe and emergency drain pipe?
Something like:
As you can likely tell from the diagram I plan on running a full siphon on the 1 1/4” main drain and have a 1” back up drain.
Is this a bad idea? I think tuning the full siphon would still be doable and don’t think I’d be risking flooding since with a full siphon I should be able to still drain 1000gph+ (I think). Plus I’d still have the 1” emergency which still should be able to handle close to 1000gph. Looking at between 600-800gph on my returns.
