What's on your mind, he's digging a trench not a gutter.

Still wondering about the porch which is in the way. How do i install the pipes? Dig through to the other side? Maybe dangerous with massive slab of concrete. I assume there are no foundation for the concrete slab. Or do think there should be?
Seems to be a trouble spot in the basement near there too. Damn there is always another thing!

All the safety stuff that you need for underground mining.
When the dig a hole for a foundation they dig it big so five feet of dirt beside the wal cannot be trusted to be safe and stable, it may be but you don't want to trust it. So the deeper you go the wider you want the trench to be.
The slab has to be judged for how well it will st if you end up trenched out something 4 ft deep and something like 3 1/2 feet wide under the slab.
I would say the safest bet is to remove about three feet of it. If you do shore it up and dig under it back filling will be a problem.

So about a 3' trench? I guess rain would be a problem i am waiting for some good dry weather.

I was going to start with the hand digging around the spots.

Here is the plan, i wonder do i put the access pipe just after the before it?

Never hooked one up but I think you would want access to it like a small manhole or something. ??

I don't think it is good to have an air space that will just attract water. I assume it should work a long time, does the sewer really back up that far?
I meant an access pipe to the weeping pipe just before the back valve and cap going up. That's gonna be a lot hand digging.
I guess rain will be a problem with the soil collapsing.

You want to be carefull when you are head down in a trench a little landslide is all that is needed to kill you.
Did you see on the show Dirtist jobs, where the sewer line at the street was plugged and the people at the bottom of the hill were on holidays. They came home to feet of sewer in the house.

If you do rent a machine, take it out back and practice until you are comfortable. I have dug close to the house without a problem, but it takes 100% concentration, 100% of the time. My mind drifted for a second and I almost took out a column on my front porch. Luckily the machine controls were responsive.

The arm of the mini-ex is slightly off-center, so work with that side closer to the building. you will want to work from the far end and back up the machine as you go.
And I would consider doing the final layer of dirt - that is stuck to the wall - by hand after the trench is dug.

It looks like you are draining to the left in your diagram. Maybe you could avoid the area under the porch and have the drainpipes exit on either side of it, then tee them together a little way downstream.

If you have any doubt about the safety of the trench, you can shore up the sides with plywood and some boards. The boards would be horizontal and brace up against the building (like a truss)
