Gutter/sump pump drain backing up into yard

I bought a house last winter in which the sump pump and gutter tie into an underground PVC pipe which empties out into the road 75' from the house. Recently, water started bubbling up from the ground around halfway to the street. I dug up the area and found a backflow outlet of some kind that was buried under the grass. I then tried to snake out the PVC pipe from this halfway outlet, but I found that the 1/2" x 50' snake is useless in the 4" PVC pipe. I fed enough snake in that it should have come out of the outlet by the street but it never did. Tried going in from the street outlet and also never felt any resistance. When the sump pump goes off it spills 5 gallons in the street and 50 gallons in the yard! During a bad rain my entire driveway gets submerged.
What's the next course of action? I want to get a plumber to use a power snake but the wife thinks that's pointless and I should hurry up and dig up the entire run break up the sidewalk and replace everything past the backup outlet. Please view the pics and help me. First house ,no handywork experience.

I would not summarily break up the pipe.

There is a blockage somewhere in the pipe. YOu just need to find the blockage and clear the blockage.

You might remove the cover from that square grille inlet and have a plumber put a snake downthere to clear the line to the left (street).


States can help recovery from hurricanes and tornadoes by not requiring due digence or prompt and timely correction of substandard conditions, and by providing continued liability insurance where companies drop homeowners.
