I'm fitting a new radiator in my bathroom. The existing feed is 15mm reduced to 10mm for a short length to the radiator. Can I fit 15mm pipe instead of 10mm without affecting the system flows (altho' I realise I'll have to gag the flow to prevent starving the other radiators)?
Alternatively, do I have to buy a 10m length for a fortune just to use 1.5m? Could I then use a reducing set and standard 15mm valves?
