Review on 🚰 Barker Portable 5 Gallon Tote-Along Drain Water Tank by Dennis Wood

This would be a great tank if a major design flaw could be fixed: Currently the air pressure relief port has a cap that fits loosely. The moment you try to move a full tank, the lid comes off and smelly water splashes everywhere. I tried to solve the problem by gluing the cap onto the tank once it was full. This worked somewhat, but the manufacturer was able to easily fix the problem by replacing the screw cap with a screw cap. Aside from this horrible design flaw, the overall build quality of the tank is pretty good. Mine appears to have had a defect at the factory that looked like it could be fixed with a melted plastic patch. The tank feels quite sturdy and the quality of the hose that comes with it is good. Another design element I don't understand is why they used a screw-on main cap instead of the bayonet fitting used on RV drain hoses. Overall, the poor design and mediocre build quality of this tank makes me wish I had bought the Tote-N-Stor 25951. I would not buy this tank again.
