Hello,anybody got a couple of 10 inch pre-filters with gauge,20 inch or 40 inch RO housings with or without membranes,or a decent RO system complete?,am looking to set up my own RO unit and would be interested in any spare bits you might have lying about( RO housings,filter housings etc),bottom line is i cant afford new but i am wary of anything previously frost damaged. If you think you have some gear i might be interested in then send a text to 07949608079 and i will text or ring back,regards,sean brennan. Located in York.
