Hi,
I am new to this group and am not a plumber or any good with DIY infact
so be gentle with me please!
I have recently moved to a 6 year old house with an Ideal Classic FF
boiler that suffers from kettling once warm.
I have had 2 plumbers look at it, 1 said the system needs pressurising
whilst another just advised as I live in a hard water area to put a
bottle of Sentinel x100 into the header tank.
After a bit of research I thought the Sentinal option would be the less
painful.
I poured a litre of x100 into the header tank but really can not see
how that will circulate through the system?
So the question is do I just sit and wait for it to circulate or do i
have to do something to force the water from the header tank in to the
system?
As another supplementary question was the first plumber trying to rip
me off?
Thanks for any help and advice.
