Water leak, new extension- advice please

[Kelbelm]

Looking for a bit of advice please- we had a new kitchen extension, after a few weeks of using it- the concrete where the extension meets the house looked visibly damp- this area is where the old sink was located and pipe extenders have been laid to the new sink. At first we thought it might have been loose plumbing connections, plumber came and dug it up, and tightened the fittings. It started to dry, but after rain this weekend it started to get wet again. The water seems to be seeping through old pipework in floor. Plumber has ‘listened’ to mains and can’t hear leak (not convinced he has ) although it is strange that it started drying out then started leaking again. Any other suggestions on what this can be- builder is stumped and so are we.Any advice would be appreciated- not sure what to do next.

Water seems to be coming from this area, this is the hot water feed- it’s also in the direction of the external wall where there has been no patio around that side of the house due to the building work. The area has been water logged due to the rain- could that have seeped in? Or is it more likely to be a leak in the pipework?

Sorry, could you explain what you mean by this- never had building work like this done before- what has he done wrong?

The pipe has a kink in it, that needs to be cut back.

Could that be why the water is coming in? Could there be further damage up the pipe?

Push fit and compression fittings concealed?

Out of sight out of mind.

Out of sight out of mind.

Clearly not in this case

Push fit and compression fittings concealed?

What should have been done? The plumber was sub-contracted by the builder and I have no idea what should have been used.

Sorry, I should have worded it as embedded and concealed in a solid floor. Basically they can use whichever fittings they want to, but need to be protected against corrosion and in your case undue warming (hot and cold touching each other). Would have been better spaced apart and in a purpose made channel so if needed the pipe can be withdrawn for examination. Not cemented/concreted over.
