      Guide Steps

      Step 1

      The old safety valve - seen in the first photo already expanded - is screwed on the pump. It is replaced by a combination of safety valve and pressure balance valve. The diaphragm valve dampens the shocks of the pump, making the flow of water quieter and quieter.

      Step 2

      Remove the two hoses from the valve. For the thicker hose you have to squeeze the hose clamp with pliers, push it away and you can pull off the hose.

      Step 3

      Pull the pump slightly out of the housing in its rubber mount. Place a fork wrench SW 12 on the pump tube.

      Step 4

      Make sure that there is a sealing ring above the thread on the valves, marked yellow in the photo.
