Hi, I wonder if anyone can help with some advice. My builder has laid a new concrete floor. I've just noticed that he's set plastic water pipes into the concrete but I'm sure i've read somewhere that the regs specify that 'potable' water shouldn't be set in concrete floors. Is this right? If so can someone direct me towards the documentation. I've had a look at: http://www.planningportal.gov.uk/uploads/br/BR_PDF_AD_G_2010_V2.pdf but can't find anything.
Cheers
