After the last very heavy rain storm my basement flooded as the floor drain could not keep up. The floor drain is connected directly to the public sewer. The floor drain has a 4″ compression one way valve, which seemed to not work well during this surge.
I’m thinking of installing a backup pump (it would probably only activate a few times a year). The problem with a sump pump is that I’d have to dig out a hole, which would be lower than the current drain. I’d rather use the passive drain most of the time so it would not use as much electricity.
I’ve thought of using an automatic utility pump, but those don’t seems as durable as sump pumps and as such carry shorter warranties.
The other option was to dig a sump pump pit, but at a depth that the pump would not activate unless the drain failed.
I’d appreciate feedback and alternative ideas.
