Adding inhibitor to sealed system

[autolycus]

Hi,

I changed over to a sealed system about 4 weeks ago and have held off putting any inhibitor in the system until I can be certain that everything is working ok.

First question is: will I have done any harm running the system without inhibitor for about six weeks (which is what it will end up being by the time I have done one last little bit of work)?

Second question: my plan for how to add the inhibitor was simply to drain the entire system, then pour 3 litres of inhibitor (it's a big system) into a downstairs vertical towel rail, and then refill/repressurise the system as normal. Is that a satisfactory method that will get the inhibitor distributed round the entire system ok?

Thanks in advance.

David.

Yes thats the easiest way to do it, also although not ideal i don't think you will have done any harm if only 6 weeks. P.S. read the instructions for the amount of inhibitor you need even on a big system (?) 3L seems a lot but it wont do any harm.

If you've changed to a sealed system then presumably you have a filling loop, in which case go to plumb centre and buy yourself some fernox express, which will require no draining down at all

Nice idea, bit already have a load of X100 that I need to use up.
