We got flooded last year - and part of the renov included gutting up the floor and installing a checkvalve from the street sewar.
In Hindsight, I would have also installed a ball valve right behind that.
So Sandy has come and gone.
Unfortunately, we lost power as well.
The checkvalve did not work at all as we got backup that just coming and coming......
I wad hauling out 5 gal buckets until 3 AM
I hesitated on owning a generator (just due to infrequency of usage - maybe 1X every 3 years) but since have gone ahead and ordered one...
I still have a couple of days....till I pry the cover open to check the door operation, but if anyone can shed some light aside from something restricting the door from closing....as to why it would have failed/let water past the door, I'd love to hear some feedback.
And OR advisable solutions on whatever other plumbing things I could do to prevent the water backup.
Regardless of Sandy or not, it seems more reoccuring that if we get HEAVY water in a short amount of time, the city sewars just can't keep up.
It's not localized to my property but everyone on the block.
