8 bids already with 6 days to go .............. Looks a good buy but for the right price. From the look of the pump and filter bowl, it have had a fair bit of mileage.
I would personally calculate into spending £300.00 + on R/O the with new filters, r/o membrane and Resin, although maybe not immediately. If there is a battery in the box then maybe that will also be well into its working life.
