Hello,
I am having a pretty tough time deciding if my linked dry-well was done in the proper way.
I live in a town where homes are separate, but right next to each other. We have been in a drought, but recently have gotten a ton of rain. And, surprise, the back yard flooded. In some areas, we had about 2" of water. Yeah, I learned our yard is the lowest of our 5 adjacent yards to the North, North East, East, South East, and South.
The scenario is that we have two low points in the back yard. One, next to a downspout is closer to the street. This area doesn't flood, but the downspout threatens the crawlspace. Second, next to a patio near the garage, does flood. Here is what it looks like:
To help solve the issue, I have installed a pump next to the downspout and a dry-well next to the patio. I linked the two wells together, so that the pump can do it's thing for the downspout all the time and the patio when things get very wet. To prevent water from traveling to the patio area, I put a kink in the linkage pipe. But, I fear the kink was too aggressive and will prevent proper patio drainage.
I think my mistake was installing the patio dry-well outlet too high. It is basically just below the ground surface. My thinking was that this should suffice to prevent flooding as water should flow to the pump if it nears the surface (water nearing the surface likely occurs at both wells anyway...). Also, I can spare the pump a little by not unnecessarily putting every drop from the dry-well into the pump well. Most importantly, I can prevent water from coming from the downspout to the dry-well. The design looks like this:
So, the question is, where should the linkage pipe be installed. Or, more importantly, at what height? And, more specifically, at what height at each end?
Thank You,
A
