The regulation states that any fluid of category 4 or 5 must be separated by a double wall in order to comply. It is generally accepted (but debateable) that the change of fluid category associated with showering is at the point of the trap for the shower where it passes from its lowest possible category of 3 to a category 5 fluid on joining the rest of the waste system. There are certainly some circumstances where the shower waste itself prior to the trap may be deemed as a category 5 fluid.

Therefore, in order for a single walled product to comply, additional design and installation requirements are required.

The primary implication of this it that a drainage trap must be installed downstream of the unit, and therefore a trap should not be installed before the WWHRS. Removing the trap from the normal position at the bath or shower tray, and then relocating it downstream of the WWHRS unit (often on the floor below the shower or bathroom), can present several significant issues to both the installer and homeowner:
