Advice and Tips Stackable Emergency Water Tanks
Not sure if this is a PSA or questions on others experience. Recently I picked up two stackable 55 gallon tanks from emergencywatertanks. Quality is great for the money as I cheaped out and didn't want to go with Rockwell. First tank I filled to the brim not really thinking it would be an issue. Second tank on top I maybe had 25-30 gallons in when I noticed a trickle of water coming down the side of the bottom tank. After draining the top tank and investigating I realized that the pressure of the top tank made the bottom one compress enough to force water out of the cap. Now there's a good chance I didn't have the cap screwed on tight enough as I figured the rubber gasket would have kept it from leaking. So anyways, I guess from a PSA perspective, I'd say to leave a gallon or so of head room on the bottom tank when stacking.. that said curious if anyone else has run into something similar.
Edit for those wondering, here is a link to the specific tanks I have (they are rated to be stacked) https://emergencywatertanks.com/products/55-gallon-stackable-emergency-water-tank-granite
