Nature's Head® composting toilets are supplied with an 8.3l integrated urine tank. If this integrated urine tank is to be replaced with a larger, external urine tank, the integrated tank can be removed and the urine drain can be routed to the external tank using this 32 mm HT pipe.
Depending on length.
With large external urine tanks, odours can form if the tank is left standing for a longer period of time. To prevent these odours from backflowing, we offer an adapter with an odour trap for connection to an external urine tank that is compatible with the DN32 HT pipe.
