I have a caravan with a water filter under the sink. It has a separate tap to the main water tap, but is from the same feeder line. The filter I have is labelled NRV 100-053. It states it is a 6" cartridge, 6000l, max flow 1.9LPM and max pressure 8.6 Bar. Do you have a compatible filter to replace this one with and if so, what cost to get posted to Australind, WA, postcode 6233, residential address.
