Hi folks, I just bought a couple of shower trays, and with them came two McAlpine top-access shower traps. These are very compact, and are described as having a 19mm water seal. Am I right in thinking that the Building Regs/Water Regs require that traps should retain a minimum 25mm seal - I think it may be part of the drains test?? If so, will the BCO accept these shallow traps? These shallow traps seem to be sold in several DIY Sheds, so I guess they work OK...
