I have 6″ white pvc pipe sticking out of the ground a few inches at one corner of the house where a downspout could be connected to it which isn’t. Looking down the hole it goes down about 8 feet to the foundation and makes a bend (I assume this runs down and out into the the city’s drainage system.) Since this is not being used with the current gutter configuration I was wondering if I can connect and underground drainage system into it.
I have standing water in the back yard and was wondering if it’s a bad idea to connect black 4″ drainage pipe into this white PVC about 2′ down.
My main concern is overloading this and/or getting silt into this existing system. I planned on wrapping the drainage pipe with landscape fabric and gravel minimize the dirt getting into it.
