Grundfos pump installation

[stevehayes]

when fitting a new grundfos pump, 15-50 (like for like replacement) do the wires go into the junction box in the bathroom in a certain order? is this a standard order for all systems ? will the new pump have instructions on this ... ? is this easy to do? thanks all for your advice!

the wires go into the pump

 

[stevehayes]

yes i know they go into the pump!!! but they also go into the junction box on the wall (plactic with a screwed cover)!! the cylinder stat and three port mid pos valve also go into it as well as other leads. !!!

you dont have to disconnect both ends to change a pump

 

[kevplumb]

so leave them in the box and change them at the pump end

Yes. The wire goes between the pump and junction box, this is what I do.
No need to renew wire, easily get lost in maze in junction box. Just replace pump and refix wire.

doing one end is proper, unless you're thinking of rewiring the house because the pump is shot!!!!!
