Guys, guys guys !! Not a lot of love on this debate !! 
I think that to shift the stubborn bits of rust and such, in rads at least, you can purchase a "rad Hammer", which you fit to a drill with hammer stop, and vibrate the cold spot on the offending rad.
With regard to powerflushing, as long as it shifts the majority of cr*p in the system, then this must be a good thing. You can always go back to the old way and take each rad off the wall and flush it outside with a hose.......
Its funny how a relatively simple question creates a thread with sooooo much condascention and animosity!! Makes me chuckle
IMO, easier to respect other peoples advise, even if its different from yours, and as long as its good info, than to verbally abuse others. Why do you guys think that the plumbing forum has the most hits on it ? Because there are several different ways of getting the same job done...... and don't get all specific and say, " well actually there are certain things you do need to get specific on, blah blah, blah....." you know what I'm trying to say

Perhaps it would be quicker if softus explained how to remove the remaining 10-20% of debris in a system.
I guess from his long winded and argumentitive approach he has either no intention or an inability to do so.
I always powerflush systems with either x400 or x800 and use a combi mag aswell. Was amazed at how much quicker it was at removing the iron oxide that then allowed you to tackle more of the remainder thats left.
We will never be able to remove 100% in my opinion and to achieve 90% is acceptable. A magnaclean or similiar to help maintain the system afterwards is the best we can achieve. If you put a y strainer on the return it has the ability to stop the carp getting into the boiler but it could affect the pump if the flow becomes too restricted.

It would be quicker, if I knew how to.
I don't know, and I never implied that I know.
Does this mean that you consider removal of a mere 80% to be unacceptable?
A filter won't stop corrosion; only correct pipework, correct cistern water level (where applicable), and correct dosing will prevent corrosion.
Isn't a new pump a cheaper/quicker option then replacing corroded radiators and a blocked heat exchanger?

Maybe? Are you unsure about it?
And could you explain what my profile has to do with this question:

gas4you believes that powerflushing won't achieve more than 80-90% removal of deposits, which means that 10-20% of them will be left inside the system.
So, what proportion of "crud" in a system will have affect how a system works?
30%? 40%? 50%?
And what proportion of "crud" in a system will negate the dose of inhibitor?
It is the mobility of the dirt that will create the problem. This is mostly in combi boilers where it can block the plate HE.
Dirt well coagualated in the bottom of a radiator which has already been properly power flushed is unlikely to cause any further problem.
There is a wide variation in the effectiveness of different powerflushing methods.
Some of my trainees have said they did power flushing previously by just connecting the pump to all the rads for a couple of hours some with and some without chemicals. PROPER powerflushing is a very energetic activity with the flow being reversed several times on each rad in turn.

1stly the 80-90%, in all due respect to the quo tee, is an opinion, so the question has no standing in serious discussion on the subject.I assure you that I don't do sarcasm.
Do you have anything to offer on the question of getting rust particles out?
I suggest you research the question before making your point on the subject.
For the record though & the benefit of our readers, the effect of the amount left in a system will depend on many factors,, as quoted by Tony being 1 factor !!
My previous quotes were valid and very useful but you decided you needed an ego boost but made a very wrong decision in choosing ME to do so!!
People like you who hide behind a keyboard and a screen and act condescending are just trouble making wimps IMHO.
Would you be like this to someone face to face ? I doubt it unless you thought you could get away with it !!
I don't know why you didn't say so at the outset, and save us all a lot of time.
You have the right to suggest whatever you like.
It's a complete unknown then, other than the fact that Magnaclean won't remove the rust particles that aren't stuck to bits of Magnetite.
Au contraire - I was looking for information, and you completely failed to provide it, and you got all snotty.
I asked the question of several people, but you're the one who turned your posts into an information-free zone.
And there it is again - the personal comment.
And there's your veiled threat again. I guess that's what makes you big and tough.
