I have an issue with mine. Silt builds up over the pipe. And I forgot to shop vac it out after the first 8" of rain. Yesterday's 2" made it flood into the basement.
Using cocorahs totals, I'm almost an even 10"
It amazes me though how unsoggy my back yard is. Back in May with all the rain it was a pond. With this rain, it's not bad at all
I noticed this morning I had a clogged gutter on my garage. Fortunately it shouldn't be any big deal since it is sloped down to the road at that spot.
A clog in the back of the house in this rain would be very bad.
Cocorahs has me in the 5" range, though you sure can't tell. Barely any puddles around.
We went camping (in a mini cabin thank goodness) at Martinak State Park. They had upwards of 3". Thankfully my canopy didn't leak
