Hi all
Hope everyone is safe.
We have Storm water going into rain tanks and have outlet which takes excess water out. But in recent heavy rains I found that in-spite of the whole thing working effectively with volume of water coming through it spilled over in basement.
Water wasn't clearing fast enough. I was thinking of putting a diverter in storm water inlet and connect it to outlet and when I know rain water tanks are full and anticipating heavy rain or going on vacation I might just divert directly to storm water drain by putting a T join. Thanks for help in advance.
