Sump pumps for townhouses
That woman is coming back from her Thankgiving trip to her family, and she's expecting me to give her good adivce.
I have an end of group townhouse that is twice as long as it is wide. Water can seep into the basement on 3 sides. Yet my sumppump is good enough (except once a little bit in 39 years.)
Her house is in the middle, with neighbors' abutting her house on both sides. How do they handle the back of such houses? The sumppump is in the front. Do they have a French drain in the back too, connected to the pump in the front? That seems unlikely. How would they do it? A pipe back to front under the floor of the basement and then back up to drain into the sump?
Yet the must do something to keep water from seeping in? My French drain goes around 3 sides of the house. There is one pipe comeing in from the side and the rear, and another coming in from the front.
I've wondered about this once in a while for years.
