I am looking to fit new radiators throughout the house which currently has 8mm microbore to the radiator valves. Currently has really old rusty radiators with manual valves etc.
I've decided 15mm TRVs will be best to allow future changing of pipework when a new boiler is installed (hopefully later rather than sooner)
I am planning to use 15 to 8mm reducers for this but should I also be adding a couple of inches of 15mm pipe to the top of the reducer to allow for the fittings of the TRV? I've not yet ordered the radiators and TRVs to tell if this will be necessary but thought I'd check here for the general norm.
Cheers
Dave
