My central heating system is currently piped using microbore (8mm)
copper pipe.
As I decorate each room, I will be renewing the radiators, and would
like to fit 15mm copper to the valves and connect this to the
microbore under the floor using a reducer. (re-piping the entire
system is outwith the scope of the project!).

Could this cause any problems?

Thanks,
Mark.

Why might it cause problems?
Or why am I doing it?

Can't think of any, if you do the plumbing soundly!

I would guess it is that the 8mm bore looks crap, bends when hit with a
vacuum cleaner and you are limited to the choice of valves should you need
to replace them.

Sorry, why are you doing it?- Hide quoted text -

- Show quoted text -

2 main reasons for doing it - (1) the microbore is not "straight" - it
curves out of the floor and attaches to the values - looks a bit messy
- and it's caked in years worth of paint, and (2) when removing the
rad for decorating, the 8mm pipes are very very easy to bend and cause
a leak.
