Fixing an underground outside pipe

bungaro79

Hi all
just looking for pointers on how to get a job sorted. We got a drains report last year when we bought our house. We knew we had to get the gullies out the back sorted but the engineer said it wasn't urgent but to get it down when we had a bit of savings. So, I'm just wondering is it just a builder I need to get onto to to get this sorted? I've attached the section from the drainage report below (if might make more sense to people on here!). Is this a big job? Am I right in thinking they will have to dig up the gullies and pipe to fix them?
Thanks


"The first foul access junction located at the rear corner has one inlet from a gully
taking kitchen waste with two gullies on line at the rear of the extension and a
test here showed a major leak."

We had a problem with sewer pipe. Got Dynorod to inspect it, identify the problem and fix it. Required some sort of cement work. Wasn't cheap, but its a shared line, so all the neighbours chipped in.

As suggested get some video work done as the leak may be fixable by lining the pipe with fibreglass with a big dig, depends on the extent of the leak
The video work will also give you the exact location

Do you mind me asking how much Nick?? I am trying to find the video of the inspection, pretty sure I saved it someplace. I didn't realise that Dynorod actually fixed stuff like this, I thought I would need a builder of some sort??

Does that not indicate you've to separate the grey water from rain ? Or am I reading it wrong. Also there's a leak

Sorry Bungaro, I unfollowed the thread, as I can't offer expertise. Hence not responding sooner to your second question.

I think it was about €450 for the survey, and possibly for the subsequent work it was about €1100.

Basically rats had nibbled away at the edges of a manhole and were scattering the gravel along the pipe, causing regular blockages.

Dyno Rod did the survey and gave us the video and the bill, and a recommendation for repair. This involved installing some sort of swinging door in the pipes, and repairing the damaged bottom of the manhole. No digging needed. However, the guy previously told me that even damaged pipes can be fixed by putting some sort of sleeve into the pipe.(we became quite friendly after all the visits :eek:. Had a naughty neighbour who insisted on flushing nappies, despite the numerous newsletters I put in the letterboxes).

In our case we went for one stop reputable company, to make it easier to get the money from the neighbours - proper invoice and all that.(it wasn't even in my garden!!).

Good luck with it.

Listermint, I've attached a picture of the area in question. The previous owners built an extension and there are gullies around it. Number 1 and 4 seem to get clogged up pretty badly but 2 and 3 seem to work fine. From looking at the picture, 1 and 4 aren't connected though so I'm assuming that the leak is between 1 and 2.

Nick, thanks for that. I'm hoping they can be fixed without digging but its good to know that DynoRod do this kind of work. Might get onto the guy who did our video inspection and see if he can recommend anyone else locally in Cork.

That reads to me like you need to separate your rain gullies from the kitchen waste . It's either the kitchen is going into the ground water or the gullies are going into the sewerage. Either or. But has to be remedied

Thanks Listermint. Is this a builder job or a DynoRod job, just so I can make it seem as if I have some sort of clue when I get people in to check it out?!

It just says a rain water pipe is connected to the foul line.
As far as I’m aware,I’m an old plumber that’s been around a bit, that’s no problem it’ll keep the pipe nice and clean.

There is two sink connections into the foul. This again is normal and proper practice.

There is a leak. This is your problem.
Dino rod type companies are expensive but will have the job done fast and proper. You could kango the ground up. Cut the pipe and replace but that is very likely to end up costing more than the company.
You don’t need a builder unless you want to ad another 20 per cent to the price for no other reason than the builder ringing a cheaper version of dyno rod.

Great stuff, thanks for the clarification. I think I'll give them a buzz on Monday and get a quote and go from there
