My Worchester Heatslave oil boiler appears to be weeping oil around the pressure adjustment valve on the Danfoss BFP 11 oil pump that is attached to the burner. The weep is specifically coming out of a small hole in the side of the brass tube (P1 in the diagrams). Is this new pump time or can I simply replace an o ring/diaphrargm? There appear to be 2, one seating the pressure adjustment valve as it is screwing, an another that seems to have a square profile, I'll try and add a photo tomorrow. If I need to replace the oil pump, I think the pressure needs to be around 115-125 PSI. What would be a suitable pressure gauge to use?
Boiler will be serviced in October so will get it checked professionally then.
