I have been given these two sumps that I would like to merge together into one almighty sump. The leftmost sump already has a bulkhead and is plumbed to have this little dongle thing coming out of it, so I want to drill the other sump and connect them via this tube. I do not believe the water will go through as it is the same elevation (both sumps) so I was wondering what I can do to make this work without spending 1 billion dollars. Thank you! I have one spare pump so I could just do like a hangover thing and have the pump in the left sump's chamber shoot water to the right sump, but I would rather not if possible.
