Hi,
Moved into new house to find that I have no CH or hot water. Under more detailed inspection I find the CH pump is red hot to touch and when I opened it I was unable to turn the spindle. I have researched how to replace it and having done a few plumbing repairs in the past I am going to replace the unit. Some questions
The unit has the markings 15-50 130 p/N 59525469 on the outside. and PC:0402 which I thinks means its 16 years old and not made anymore. How, or where, do I locate the right replacement part that will mean I can replace exactly with out having to change the pipework? If I get another pump that 130 mm 15 bore and 50 does the guarantee it will fit i.e https://product-selection.grundfos.com/ ALPHA1 15-50/60 130?
Either side of the pump there is an isolation stopcock so if I lock these off I shouldn't have to drain the whole CH system?
Any other considerations I assume the ALPHA1 15-50/60 130 will work with my existing Honeywell st6400c
thanks
Adam
