I built my first sump recently and I did not really take into account the size of pump compartment. There is no "max level" where water wont overflow if you keep it below.
When I turn off pump, it looks like it will overflow the entire sump. Of course, all is good right now, and I am looking at getting a backup batter. But, does anyone have any clever fixes that will divert back flow?
I do have a valve on distal (to tank) that I can shut off (still over flows). I also have really tight plumbing on the proximal portion (to sump), where it would be hard to place a valve.
But, I am sure in the history of sump making someone else has done this and has some clever work-around. Any tips?
