Does this pipework look okay?

I've had a plumber around today to look at the pipework behind the washing machine area. I was hoping that the MDPE piping bringing the water supply into the house could be terminated at the wall, and an elbow joint used to transition to copper piping along the wall, to join with the existing copper piping. The idea being that this would reduce how far it sticks out (initially was around 6cm out from the wall), and would be a better material in terms of heat resistance, as the washing machine can get hot.

What they have actually done is to bend the MDPE pipe, which looks fairly well kinked to my untrained eye, to route the MDPE pipe along the wall, and then gone up from there to join to the original copper piping. So the MDPE pipe sticks out just about as far from the wall (possibly 0.5cm less), albeit in a slightly better position, as well as now appearing to be kinked.

Can anyone advise on whether the MDPE piping is safe as it is, particularly if it may be subject to heat from a washer/dryer? I've tried to show the kink as best as possible.

If this is not safe as is, can anyone suggest a way that this can be redeemed? I'm struggling to see any solution. Any thoughts or advice massively appreciated.

At the moment it feels like I've paid over £250 to make the situation worse, or at least to not improve it in any meaningful way, but hopefully I'm being overdramatic! Previous setup included for reference.

Good Grief, that is appalling. What is the arrangement of the MDPE externally to start with, it shouldnt be poking through the wall like that! Need to get the external sorted before worrying about the internal.

And who fitted that waste? Its rare to see so much wrong in one picture!

That is not of the work of a Plumber by the way, whoever you employed should stick to playing with water in the bath.
 
Thanks for the replies. The MDPE I believe goes under decking, then through the external wall underneath the decking level, and through the internal wall where you see it there. So as pictured in the original set up, it follows an upward trajectory. This is as far as I can tell from poking around, but have just moved in recently so not privy to the full history.
 
Service Pipe needs installing properly, partly to protect from Frost and partly to satisfy Water Regulations. Should be 760mm deep in the ground, then brough up either internally through a suitable duct, or use a Groundbreaker Insuduct to bring it up externally and then suitably insulate the service through the wall.

Putting a bend on the end of what you have there is just a sticking plaster, the whole thing needs doing properly. Given the state of that sink waste, whoever has been let loose on the Gaff was/is a complete Cowboy, from what I've seen and heard in these two posts, the plumbing is utter carnage.
 
Thanks again. Essentially there is nothing that can rectify the errors made today, or would it at least be less of a risk of the MDPE pipe was re-routed back along its original trajectory so that there is no kink?

Ultimately though, this is going to be a pretty big job to fix then. Any thoughts on very rough costs for this kind of work?

Not really, that pipe has been damaged now and badly scored by the looks of it, nigh on impossible to get that back to any real normal condition it needs replaced - properly.

As suggested the whole mains run needs looked at, as to how it exits the ground outside and then as it's routed and then enters the building.

The sink waste, as suggested, needs looked at too, waste water won't run up hills properly, especially like that heading out the wall, which means that whole section of waste pipe up to the level of the pipe exiting the wall will always be full of waste water. That will only lead to problems with poor drainage and blockages in the future. That needs sorted too.

Cost is usually dictated by location and work required, without knowing the whole extent of the required work then any figure wouldn't be accurate. You need to try and get a hold of an experienced & recommended plumber.

Have the shysters that did that been paid, I'd be ripping them a new one at this point and showing them the door if I was over seeing that TBH.
 
Thanks for the really thorough information, it is really helpful and massively appreciated.

They were someone that I found through MyBuilder, and yes I have already paid.

I have been advised to pop down to my local plumber's merchant to get recommendations for decent local plumbers, so will be doing that shortly.

Don't use that platform.
I tried to use it to get work.
It was bad enough to start with but at least you could see profiles of the customers looking for work and those tendering for it, so you could get an idea of calibre etc, then they changed it so it was completely blind bidding.
Paying a shortlist fee - just to get contact details - so that, only then can you ask all the important questions before tendering!
No Thanks!
Some clients posting jobs are genuine, many are not! And you can't tell which is which until you've paid the fee.
If that's the sort of quality I was competing with, then even more glad I gave it the heave-ho!

I can't see the external entry point unfortunately as it seems to be under the decking. Given that the pipe is damaged now and needs replacing anyway, makes sense to reroute/insulate it and have it enter the house properly at the same time. Appreciate everyone's advice on this.
 
The MDPE, depends on what the situation is outside. If it suddenly rises from the ground and through the wall, then probably not too big a job to bring it into the house properly, however if it's been run a couple of inches below ground all the way to the boundary, then there's going to be a bit of digging involved. I'd be pulling some decking boards up and having a look.

Sink waste is slightly more straightforward, needs a new hole knocking or coring through the wall, and a new waste pipe putting through at the correct height. Once outside if going to a Gully, reroute as required, if to a stack, then new connection made, again at correct height and existing blocking off. Remove old waste and make good redundant hole in the wall.
