Hi all,

We will be having our system power flushed (as new boiler put in and
loads of sludge) and the plumber has suggested putting a cleanser in a
few days before. I thought a cleanser was instead of a power flush? Is
this really necessary?

I have had a few issues with him and wondered if he is going to
'pretend' to power flush but actually do a chemical clean instead.

Your thoughts would be much appreciated.
Many thanks
Rebecca

I'd guess the cleanser is to dislodge the scale prior to the flush.
Power flushing alone is unlikely to be very effective I would have thought

Really both the chemical before and during the use of the machine are
good.
If you don't trust the guy to do the right work why are you using him?

As he was the plumber contractor used by the building company that did
our extension so its incompleted work! I realise that sounds odd
without that explanation! Thanks for your input.

It is worth doing IMHO. A chemical cleaner can't actually remove
anything from the water without a flush, but it can help dislodge and
break down sludge in the system prior to flushing.

(it will only cost you £15 ish for the cleaner, so why worry?)

How long can the cleaner fluid be left in the CH system?

It will probably tell you on the back of the bottle. IIRC when I did
mine, I stuck the cleaner in a week or so before decommissioning the old
boiler...

Due to ill health, as I mentioned on my posting of an article about
grinding a twist drill, I have not been well enough to drain my system
down. It has cleaner in it from late last year. What damage can it have
done?

Probably none... if you read the spec[1] on Sentinel X400 for example it
says:

"The product should be circulated, preferably at normal operating
temperature, with all valves open and the pump set to maximum flow for a
minimum period of 2 hours or until satisfactory performance is restored.
Where systems are badly fouled, a longer period of circulation (e.g., up
to 4 weeks) is recommended, but the product will not clear a completely
blocked pipe. There is no limit to the time for which the product can
safely be left in the system."

Many thanks John. I am slowly getting there and I will post details on
both subjects soon.
