[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]It should be fine, OP. Not ideal but your house has perimeter drains and if they’re working properly, they can handle it. [/quote]

Utter nonsense.

If perimeter drains could handle it, why would the house have gutters and downspouts?

There was a time after perimeter drains were introduced, in the 50's and 60's, when people thought they were magic and could handle any amount of water. Houses were built without gutters and downspouts. Those that are still standing were retrofitted with gutters and downspouts. [/quote]

All homes built after 90s have exterior French drains and sump , you should be able to not ever have water in the basement even if a downspout fails. [/quote]

Again, utter nonsense.

A typical summer rainstorm might drop an inch of rain in an hour. If a house has one thousand square feet of roof, that's 83 cubic feet per hour, or 667 gallons per hour or 11 gallons per minute. The perimeter drains are a horizontal pipe, they're going to be completely overwhelmed by that level of flow.

They are meant as a backup for any water that gets past the gutters and downspouts, they're not meant to take the whole flow. [/quote]

Okay but one storm? Wouldn’t the water just sit by the foundation for a few hours waiting to drain? I’m not saying it’s good but I would be shocked if that led to an immediate problem. [/quote]

Depends a lot on the type of soil.  Many parts of the local area have maybe 1-2cm of top soil and then marine clay.  Water sitting on marine clay is mostly going to sit in place unless gravity pulls it away from the foundation.  Slopes downward by the foundation on all sides to pull water away are terribly important.[/quote]
