I have a large (30 gallon?) Brute trash can I used for storing RO water. The RO system in the bottom of the can is a Spectrapure system that will need all new filters. The can also has the float shutoff where the RO water came in. The other two fittings on the can are an overflow (in case the float valve failed) and where I plumbed a submerged pump (not included) to an outside hose for easy filling of top off buckets. The slot cut in the cover was where the cord for the submerged pump went. From new the can was only ever used for RO water storage.
