The Vertex Replacement RO Pressure Metal Tank stores purified water produced by your reverse osmosis system and delivers it to the faucet with steady pressure and reliable flow. Designed as a direct replacement for compatible Vertex RO systems, this durable metal tank helps restore normal draw volume and performance when an existing tank becomes worn. Replacing the pressure tank is an effective way to maintain consistent, on-demand RO drinking water in residential and light commercial installations.
(The standard 4.0 gal plastic tank Vertex POU Filter Systems are no longer available and are being replaced with this 4-gallon metal tank instead)
