I used the VEVOR 36QT S.S. stockpot for the bottom half of an 8 GAL water gravity still filtration and an import locking top 31 L S.S. stock pot to build it. I used a step drill to cutout a spot for one stainless steel spout, and complete the 8 gallon water filter system. Drilled a hole in the top stockpot for the filter. Commercially sold 3 gallon styles don't provide enough water for one person per day. I designed 2 flat aluminum bars into strapping bands together with a 3 piece cutout white cutting board to anchor the 2 stockpots from sliding apart. Not you average use for these stockpots, but saves money on a bigger gravity still water filtering system. Also, drilled a small hole on the top side of the VEVOR stockpot for equalizing air pressure so the water would filter down easily, otherwise, a vacuum is created and the filtration will stop. Taped a small glass cap over the drilled hole to keep it clean. A great camping water filter system when you need more water too. Besides this, the VEVOR 36QT is built thicker than most stockpots, and the welded handles can hold the weight. A good value for the money.
