  • Do not pull the front panel too far, it is still attached with different hoses and cables.

  • 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.

  • 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.

  • With the thinner pressure hose above you have to pull out first a clamp, then the hose comes out easily. There may be a gasket on the hose or it may stick in the valve.

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

  • Then turn out the old valve.

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

  • First screw the safety valve into the pump tube. Do not turn too hard.

  • then screw the pressure regulating valve into the safety valve.

  • Place the two outputs on top of each other.

  • Put the two hoses back on. Also pay attention here to the thinner tube on the sealing ring, if possible, a new one.
