Don’t forget about the “Water BOB” that fits inside a tub. About $30 and it’ll hold about 120 gallons of water, IIRC.
I have some surplused USGI 5gal/20L plastic cans bace by Scepter. Tough to get replacement parts, but the best cans ever made.
Thank you for an excellent Christmas gift idea!
My parents live in a rural area and have well water, which doesn’t work during a power outage. This beats filling up gallon jugs in preparation for a storm.
