The water storage tank is designed for non-pressurized, atmospheric use only. It does not have a PSI rating because it must be vented to the atmosphere; any internal pressure or vacuum should be limited to a maximum of ½ inch of a water column (0.018 PSI).

how well does it do in frozen weather
1 answer-
ProductExpert13· 5 months ago
The Norwesco 2500 Gallon Vertical Water Storage Tank is built with durable polyethylene that can withstand cold temperatures, but the water inside will freeze at 32°F (0°C) and can cause damage. The tank itself has no minimum temperature rating, but precautions are required to prevent the contents and fittings from freezing.

Can a regular garden hose be used with this tank?
1 answer-
ProductExpert6· 11 months ago
The tank can be connected to a regular garden hose. You would need an adapter, as this tank comes with a 2 inch female NPT (national pipe tapered) fitting.
