Use Sentinel cleaners visit www.gebetz.com/sentinel - I've just done mine; I asked on this site whether I could leave the cleaner solution in longer than the 2 hours recoomended. I had replies saying it wouldn't matter - however when I visited the site above it said you MUST not. Best of luck
JAMES2, are you a salesman for Sentinel? This is an identical reply you gave to another post this evening There are several other manufacturers most of which are satisfactory. Cleaning out the system will not cure all problems though.
oooooooooh

No sorry - I didn't want to promote any products, but I found the website really useful when I had a similar question. Your right, I'm sure there are equally good, if not better alternative products. I reply with the same message as it equally applied to another question
it says on the website theres no limit to how long you can leave it in
Found it on the web site under frequently asked questions....
How long do I need to leave Sentinel X300 in the system?
Sentinel X300 should be circulated for 2-3hrs at operating temperature, or up to 24 hours if circulated cold….but no longer, and the system should be flushed with clean water immediately after use.

where a new boiler or pump is to be fited to an existing system, or where radiators have cold areas or are partly blocked due to sludge build up.
Sentinel X400 is a non-acid formulation which can be used in all types of direct heating systems including those containing aluminium components.
Dosage:
Sentinel X400 should be dosed at 1% of system volume, i.e., 1 litre per 100 litrs of system water. To clean an existing system in accordance with BS7593: 1992, Sentinel X400 should be circulated, preferably at normal operating temperature, with all valves open and the pump turned to a 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.
Rapid cleaning may be carried out if Sentinel X400 is used in conjunction with a power flushing device.
Flush the system before refilling and treating with Sentinel

OK - how do I estimate the volume of water in my system?
Or is the concentration of cleaner/inhibitor not that crucial?

normal; bottle will do an average system if your not sure stick another in overdosing does not present a prob
BTW ban link move nice

Ta - I guess it's an average system - 3 bed semi, 6 rads of various sizes and a towel rail. A lot of the pipes run hither & yon because the ground floor has solid floors, but that'd only be a few more litres.
Had some new rads fitted recently (the
looks fab), and
(a) the stuff that came out was extremely murky, even though the system was flushed and inhibited a few years ago
(b) it's now running without inhibitor, which I want to fix asap, so I'll give it another flush first, for a few days.

Hi
Refering to how long to leave Sentinel x300 system flush in a ch system. The instructions on the tub say you can leave it for up to four weeks. Hope this is ok as i'm intending to leave it for about a fortnight.
Can anyone advise me wether this could do my system any harm?
Thanks
