Having posted on trouble with rising TDS, members have advised me to get an 11 litre resin cannister. Having found a couple on sites, they all have input/output male hozelock valves at the top, can anyone point me in the right direction for a fitting which will connect this to standard 1/4" RO hose from the membranes.I've found male / 1/4" http://www.cleaningspot.co.uk/acatalog/200_GPD_RO_Systems_and_spare_parts.htmlbut obviously there is another way of connecting these vessels to standard ro hoseThanksFieldsy
