JayADee: I'm not using flexible pipe, I'm using 90 mm thin wall, solid pvc. Like the 60 and 80 mm kind on your downspouts.
I don't know how to hook the pipe up to my access pit without it being stuck there with zero slope.





Connect the pipe to the 0-degree fitting. Gently heat the pipe near that fitting with a hot-air gun until it softens enough to droop/bend down to create the shallow angle you require.

?bury the square box at the slight angle you require rather than verticle so that while outlet pipe is a zero degree but the box and pipe is sloping downhill.

Then arrange soil to mask the slight angle.

1 in 100 is such a gentle slope that you might be able to just glue the pipe in then immediately before the glue sets bend the fitting slightly. Otherwise just get a plumbquik coupling (black rubber joiner with hose clips) Cut the pipe by the pit box leaving enough to join onto. Then use the plumbquik to rejoin the pipe and get your angle.

They don't officially make a 90mm plumbquik but an 80mm one should work fine.

I thought about that but it just seems like it shouldn't be necessary, know what I mean?

Thanks for the suggestion.
Have you got a link to where I can see a plumbquik?
Though 1 in 100 is the minimum recommended I was going to go a little steeper.

I do have a heat gun and this certainly did cross my mind even though pvc literature specifically says not to. 👍😀

Does it matter that much? It's only stormwater, so it doesn't smell, and you will have standing water in the bottom of the drain pit anyway. Most stormwater systems that discharge to the gutter will have water resting in them permanently

The other thing I am going to try shortly is a 22 degree and 15 degree elbow and rotate them to both get the slope I am after and see if I can negate the direction change the rotation causes at the same time.

It's so weird there isn't a simple solution for this. You'd think a straight run pipe with a slight fall would be the easiest thing to do.

Yeah, saw these in a dux brochure online, they do come in 90 mm but I might have to special order one. D156-33

Does what matter? Not having a slope you mean?

Looking at the dimensions of that plumbquik the 80 mm might just fit. On Monday I'll see if the local plumbing shop has one. Bunnings is a fair drive and I want to try it on the end of a pipe rather than order blind.

Why not use a short length of convoluted/flexible pipe at each end to give the desired 'angle'?

Its easy to squish the pipe if using a heatgun, normally for smaller conduit we put a spring inside or just do it really carefully one side of the pipe at a time. Wonder if you could find a bit of 80mm flexi to push in and prevent the pipe collapsing when it gets hot. Probably do it in the trench instead of trying to bend the pipe up first.

Hard to find fittings for it, I think the flex i is 110, the pipe I have is 90. That did cross my mind tho.

I'm still thinking about this option. I could run an extension cord out there no problem and as I said we do have a heat gun (if it still works, it's very old now!) I also have some flex pipe I could cut up the middle to make it small enough to put in, that's a good idea.

It does sound like the clamping rubber sleeve would be easiest. I've got a small chunk of odd sized pvc in the garage, I might try a melt test on it tomorrow.

I'm tuckered out from weeding tomatoes.
