Haunched? Downpipe knackered

[jacko555]

The gutter downpipe is cemented into the ground.

This has perished. I had river in last night's rain where either its blocked with moss, or, just unable to cope with deluge.

See expert pic

I know the sewer/drain (brown lines) runs left to right as there is a drain cover just out of shot to the left.

I assume the downpipe joins via the dotted yellow lines as its the shortest route.

Blue is the rather deep river I had last night. House is old (100+ yrs).

Am I correct that ideal world is it needs digging out, potentially unblocking (silt/moss) and flaunching again?

Is it also probable I'll find clay? pipes and they have cracked / perished etc?

Is this a diy job? If not, anyone want to hazard ballpark costs to renew this?

For a temp fix, I could reroute the downpipe as per below. That is the kitchen outlet drain. Then wait till warm and dry weather to dig it up and fix.

I assume this is ok, as rain, sink and toilet water all go to the same drain.

Appreciate any advice

That's fine

What combination of bends would you suggest
2x 92.5?

What about going into the water butt with a hose into the gully.

about going into the water butt with a hose into the gully

Good idea. Saves on faffing a 3m run.

My concern is if a deluge fills the butt before. it can drain. That downpipe is the only one for the entire house (detached), so is draining the whole roof.

Pragmatically, even if it did, it's no worse than whats currently happening (a stream) and the butts are on a sloped handstanding. The butt also has an overflow pipe

Nice idea. Thank you

May well be a gulley under that downpipe, I would do a bit of (careful) digging. If property is on a combined system, the rainwater would be connected via a trapped gulley. I suspect someone may have concreted it over for appearance sakes, now the gulley pot is full of crud and the water cant get away. Worst case scenario, if pot is knackered, as long as you can cut back to a decent bit of pipe, fitting a Bottle Gulley isnt difficult.
