30-50cm 15mm copper pipe (Brentwood CM14)

Hi there

I’m looking for a small section of copper pipe to fix the dire contractors my landlord hired to replace my under sink unit that was destroyed by a leak, they literally did the worst job making the unit pretty much unusable routing all pipe work through holes drilled in the cabinet it’s bleak.

I was trained by the DWP to fit bathrooms and kitchens so I’m just going to fix as much as I can to save cost of the landlord as it’s not there fault.

Any help is greatly appreciated

Kind regards

Jay
