160-320 Gallon BPA-Free Emergency Water Storage Tanks | Portable Food Grade Plastic Water Containers (2 Pack 320 Gallon) with 25' Hose & 5-Year Water Treatment - Perfect for Disaster Preparedness, Camping & Off-Grid Living

I've had my double-stack water storage tanks for just over six months now, so I'm speaking from a little more experience than "I just received my barrels and they look great!" Here's what I've noticed:1) They came decently packaged (plastic wrap on a pallet), but they did have a couple bumps and bruises. I don't blame the manufacturer as much as I do the delivery company. I saw how the pallet was stored in the back of the truck and how he removed it. Thankfully it's all cosmetic and doesn't affect performance in the least.2) Wash the interior of the barrels before thinking about filling them. I used a diluted solution of bleach-to-water, roughly one cup of bleach to one gallon of water per barrel. It's overkill, but I found the barrels to have a slight odor on the inside and didn't want that to potentially transfer to the water. I dumped the solution in, sealed the cap, and gently rolled the barrels around (so the spigots wouldn't be adversely affected) to get complete coverage. I did this for roughly 5 minutes per barrel. Afterward, rinsed them out. The smell was gone.3) While not heavy, the individual barrels are bulky. Getting them through doorways and downstairs by myself wasn't terrible, it just takes a tiny bit of core strength.4) Be sure to buy some quality water preserver before you fill. Also make sure you have enough for your ~320 gallons of water, plus additional if you plan on any form of water rotation.5) Depending on where you store your barrels, as in my situation being in the basement, you may want to also invest in a solid, high-volume water pump. I purchased this from Amazon as well: "SuperHandy Water Transfer Pump Utility 1/2 HP 1525 GPH Dual Thread 3/4" Inch GHT 40' Feet Head Lift". That has enough head to get the water up and out the basement window in the event I need to empty the tanks quickly. Hoses are also necessary, obviously.6) These have held up perfectly, each holding their max volume, without a single leak or drip from any of the fittings. I've also tested the ball valve spigots, and they work flawlessly.In closing, I would definitely recommend these water storage barrels for long term water storage.
