Fitting a Seal Kit
Changed most seals with unit fitted on the wall (recessed). Originally a Wickes branded model. Not all the seals shown in the diagrams were actually there, but most were. Used a 17mm bolt with two nuts locked together to undo the sleeve assembly holder (normal RH thread). Had to use a piece of coat hanger wire with bent end to fish out the final brass cup holding seals. Take care on reassembly that the wax element seats centrally in the spider seat, otherwise the control knob will not shut off the flow or work properly.
Job done, works a treat again.
