Worcester Greenstar 24RI - Burner Seal Replacment
Got some quotes for a service, one person has said if I haven't had the burner seal replaced for past 5 years, it should be done (& service price goes up by £55). Boiler installed in 2015 - never had the 'seal' replaced? Is it a necessary requirement just as a matter of course?

Grundfos Alpha 2 Wiring Connector
Hi, I note that the Grundfos Alpha 2 requires a special plug to connect the electric wiring. Are those plugs reusable if rewiring is needed? It's an expensive plug, costing as much as a used Alpha pump. Suppliers of refurbished pumps don't supply a plug. Fine if it is a Grundfos like for...
