I’d use a bicycle pump to pressurize a 55gall drum of water for flow but gravity is such a blessing you can’t pass up something so easy just be sure to only trickle the water as you don’t wanna waste scrubbing the soap does most of the work and water trickling helps lubricate while also the full rinse at end then rather than paper towels i use cloth towels that dry naturally hanging if ones sick but not the other I’ll have multiple handtowels even for visitors
I got 6 gallon water jugs they’re just about the weight limit i can carry reliably under full health and they too stack square and I’m developing backpack straps so it’s not just one 6 gall in each hand like 45 bags of groceries with it backpack that’s 18gall of carry capacity that’s 149.94lbs so id round to 150lbs and say i took a sip too 😂 One US gallon of water weighs around 8.33 pounds or 3.78 kilograms at room temperature. The precise weight of water varies according to its level of density, which in turn depends on its storage temperature. so i imagine you can store more cold as long as not frozen where expansion normally happens im trying to figure how to get rvc totes into the basement but for now 55gal drums 🥁 are my limits of what fits through doorways double stacked em though cause 8ft ceilings
