Product Details
Product Details
The GW20BLP (20L) and GW40BLP (40L) are low-profile, box-style grey water bladders designed for caravans, camper trailers, and 4x4 setups. Perfect for Australian camping, they make managing waste water simple, compliant, and space-saving.
The compact flat design fits neatly under vehicles or into tight tray spaces, making them ideal for modern touring setups where storage is limited.
Featuring reinforced webbing handles, heavy-duty Australian-made PVC construction, and quality welded seams, this is a smart and reliable solution for responsible grey water management on the road.
