Hi, the water in our Bailey Ranger is undrinkable, even boiled as it has a distinct 'rubber' taste to it. We never had this problem with our old Compass van. The Compass while ancient (1993) had been a high spec van when new and the water system had a water filter built in. The Ranger being a bargain basement van does not. Does anyone know if it is possible to fit an after market filter in the water system in the Ranger, or even suggest alternatives? We never drink water that has gone through the caravan straight, but it in our old van we used it for tea/coffee and cooking. We have miltoned the system so I am confident the taste is not due to microbes.
