One of the favorites of our Water Sales Department is the Tank Unit Bactericide System (TUBS). Apart from bacteria inhibition it’s basic function is to naturally, i.e. non-chemically condition/soften water and protect the expensive tank system against limescale, corrosion and metal pitting. This unassuming, compact and the lightest of the Magnetizers is sold to thousand of households that purchase $2-3K drinking water purification tanks (filtration steel tank systems, RO tanks, decontamination tanks, etc.). It is an indispensable companion to be easily slipped into the tank’s internal cold water inlet pipe. FYI We normally sell “TUBS” together with “RWE-1”, (= 1 ring as opposed to 2 rings sold with the main home conditioner “RWE-S”), which goes onto the hot water outlet from boiler/heater.
