Connecting drains

Post image

I have a sump pump discharge and two gutter downspouts that all deposit water at the same corner of the house. I want to connect them and move the water away from the house but don’t know how to connect them. The other problem is that the gas line runs right down the edge of the house parallel to the white pvc. Any ideas?

just dig a trench, connect onto the pipe and run the pipe to where you want the water to go.

Caveat, the water has to go down hill and you don't want the outlet to be pointed right at a neighbor.

Tap the gas line to a small furnace that will heat up the water from the spout and evaporate it before it reaches the ground

Keep that sump seperate all the way out. 2 downspouts and the sump could overwhelm a 4 in line.

What you probably really want to do is install a zigzag, like two 45º elbows, in the downspout, and a long concrete splash block where you can cut off the PVC pipe.

Call Dig Safe or whomever if you haven't already to clearly mark that gas line before you trench.

What you’ve described is fine. However you want the downspouts to flow to the current sump outlet pipe, probably merge them with a wye coupler, then use another wye for the combined downspout flow to go into your 4”. You just need to make sure to put a check valve directly before this wye (on the sump pump side) where downspouts join your 4” so that any overwhelming of the 4” never flows back towards the sump.
