Job went fine with no snags. The funny design of TRVs was actually a help,
as the 'top hat' olives are easy to remove without damaging the pipe - you
simply saw through the top part and slightly down the side and they break
with a screwdriver.

Since the new TRVs are reversible, I took the opportunity to swap ends on
three of the rads where this would make them more accessible. I've also
put them horizontal this time - be interested to see if they control the
temp any more accurately being sited slightly further away from the heat
source.


I've done that with a few and I think it does improve behaviour a bit.


The water when drained down was amazingly clean - as were the dribbles
from the rads. A tribute to Fernox in a pretty old system. I'll put in the
fresh tomorrow after a final check for leaks.

One wonders why people *don't* put this in. It's very cheap
insurance.
