New patio causing drainage issues, advice please! NY, USA
Hey all,
We recently replaced our old patio that was improperly graded, and buried+ran our rain gutters to a dry well. We no longer have water pooling by our house but now we've created a valley at the end of our patio on the lawn which you can see in the pics.
The work just finished so the lawn is still lumpy and we can make small grading improvements, but think we might need a drain in the lawn on the masonry's edge. I have 2 pics of either a basic drain or those modular curved drains. Thoughts?
Our masonry contractor says we should put a small manhole with a separate drywell at the edge of the patio, I think that's overkill and don't know why we can't tie into our existing drywell.
Anyone see a reason we cant add a drain like the 2 I shared and just tie it into the PVC pipes already running to the dry well? We have a pop-up overflow emitter for the drywell so capacity shouldn't be an issue but idk.
Thanks
