Replacement water supply pipe - couple of questions

[c00]

[Starting a new topic for this on corgiman's advice ]

I read on some previous posts here about using an Insuduct as an alternative to bringing the water supply pipe into the property below ground. (I'm shortly to embark on waper pipe replacement, and the idea of hanging down a 2ft 6 hole trying to tunnel through the foundations of a victorian (mostly stone) wall isn't something I'm looking forward to).

I had a look on their website and it looks good. Just wondering what people's experiences of using this were and if anyone would recommend it (or not), or if there are any other similar products around? Do you need the mdpe 'hockey stick' they mention? (Having tried bending 25mm mdpe pipe in the past I assume the answer's probably yes or it's not going to bend enough to go through the hole into the wall.....)

Also, everything else I've read about this says the water co. need to inspect the whole trench and the entry point to the house, and that you can't backfill undtil they have been and inspected it. However, the lady from Dwr Cymru just told me on the phone that they only need to inspect a 'short length' of trench and aren't interested in what's been done at the house end. She was a little bit sketchy on some of the other details, so based on this I'm thinking either
(a) she's wrong, and I'll fill in the trench and then be asked to dig it all up again. Sort of thing I might look back on in 20 years and laugh about, but probably likely to upset me quite a bit at the time.
(b) different water companies have different rules

Is there anyone in the Dwr Cymru area who's replaced their water pipes recently who can confirm what actually happened...?

Thanks (as always) for any help.

If you want an insuduct and groundbreaker box, then I have a set in the garage that didn't get used on a project. pm me if you are interested.

htgeng - PM on its way.

Still interested if anyone else can offer views on ease of installing this system vs. the conventional method.

(...or if anyone can confirm whether their water company were happy to have the majority of the trench filled in before inspection !)

Just called dwr cymru a second time for another opinion - spoke to someone else, and got a different story.....probably better if I leave the trench open, the guy said.
Me: I don't really want to. It's going to take a while to dig it all out, and I don't really want my small children falling into it and so on. I was told the other day that I could backfill most of it, and just wanted to check exactly how much of it you would want open....
Him: Well, you could fill it in and just leave a bit.... If it's a problem then they'll tell you when they come to inspect it, he says.
Me: Er, what does that mean...are they going to expect me to dig it up again?
[Cue various vague answers, repeat various parts of the above conversation a few times....]
Still none the wiser....
