Hi,

I have just finished some work on my central heating system (fitting TRVs,
changing the bathroom radiator for a towel rail type radiator and some
pump work involving some soldered joints).

I would like to refill the system and run it for a few hours to check for
leaks *before* adding inhibitor. How much "damage" is this going to cause?
OK, it wont cause damage, but is this a good idea?

If there are no leaks then I have lost some time part-draining the system
and adding inhibitor, but if there are leaks I have saved myself the cost
of the inhibitor.

Thanks,
BraileTrail

I would see no problem in doing this provided you have flushed the system to
remove any debris that could interfere with the boiler/pump. If no leaks are
found drain a little bit and then add inhibitor.
