I have an problem with the pressure control box on my pump. A recent visit from my usual service engr caused damage to the control switch on the black box causing damage to the plastic switch and the internal copper armateur. He has said it was not him. I can fix it if I could either replace the part (which comes off easily enough) or if I knew the wiring diagramme for it. Can any one help. It is a Grant Class F, PN10, TF110, IP44. WouldI be able to get a replacement part? I am assuming that I will need to buy a new pump which is anoying as the part would take minutes to replace..

the pump will be either a Grundfos or Wilo with a Grant badge. Neither of these manufacturers supply any spares for pumps, so it will be a new pump.

If it's a Wilo....You are lucky that it's not leaking.
