influenced by Dicks flushing jig, I'm making a powerflush machine, Its a jetwash which my lad bought and never uses so I've adapted the hose to fit on a rad, trials will start shortley and you will see it live as it happens,  |

Sounds good, Tom. If it works, you need to patent a special pressure washer hose that attaches to rad or pump valves.
Next stop - Dragons Den!  |

I can't see how it will not work but, just for my safety, I'll wait till Mrs plum goes out before I do a trail, cos if it fucks a pipe or fitting and we get a flood, or even worse, no hot water for a day or two, I'm brown bread,  |

I think Woodies's on to something with the patent idea. Those powerflushers surely cost too much money.
I can tell you from my point of view, my system is so totally fully of shite and I've tried almost everything (chemicals, mains flush etc) except a powerflush.
I started looking at the cost of powerflush machines and most of them are more than a bloody grand ! So I stopped looking and resigned myself to a life of half-bore pipes, noisy boiler and cold bottomed rads. I'll never pay a penny let alone £600 to the dedicated power-flusher brigade. To be fair, if I wasn't interested in plumbing myself, I would happily pay a proper plumber but not those double glazing powerflushing salesmen.
Back to the point. Using a jetwash sounds a really cool idea. You obviously get the pressure there but do you get the required flow?

Fking hell ! Just looked at the spec of a typical one. 130 Bar !!! That is definitely you toast I would think. Only 6 litres per minute flow though. Maybe though, if you open up the aperture of the nozzle (or you're not using one since direct connection) you'll get a lot less pressure and a lot more flow? Still, sounds a bit risky on your own heating? Test with a gauge first? Shame you're not working anymore, you could test it on a customer that you don't like much  www.screwfix.com/p/titan-ttb669prw-130bar-pressure-washer-1-8kw-240v/5014j |

Using a jetwash sounds a really cool idea. You obviously get the pressure there but do you get the required flow? During summer If I get a really bad F&E system I just use 25 litres of anti-freeze (G12 specification works very well and is very cheap) and fill the system with that, I use the systems own pump on a plugin timer with the central heating valve set to open. Now this is not the best method as the product is only in the system for a short period but does allow plenty sludge to be dislodged then removed when I use the mains to flushing it out. However, if the job allows it during the house holders demands for heating winter period I prefer just to leave the antifreeze in the system for a few weeks as the system operates normally - the extra time typically produces excellent results and your doing no extra work. I have (hose lock manifold gardening gear) and a clear tank with magnets inside so I can monitor whats being flushed out the connections to the manifold allow reverse flushing or single point flushing depending how the house instal is set up. When I finish I just a one litre bottle of inhibitor to the system. |

Maybe the pressure washer adaptation isn't really suitable, or just for doing a single rad at a time. Would certainly find any weak points in a system. 
As for power flushing, maybe you could hire a unit?

I have to say both very good ideas. Looks like about £20 for 20L of G12 on ebay.
The hiring I'd previously discounted because I hate hiring generally. BUt in this case, even first link I clicked (your hss one) was not too bad considering the machine costs a grand new. Delivered on a FRiday PM and Collected Monday AM would be £84.
From what Battle says I'm thinking 20L of antifreeze might be better than 1 or 2L of regular cleaner (alongside the powerflush)?
After 10 years of being in this place, I might finally get it done properly...... Will definitely post up here if I do !

On the pressure washer - I wonder what the pressure and flow would actually be if you removed the nozze? Might be something within powerflush parameters...?? |

my thinking is, as long as you always have an open end, its not going to put the pipework or joints under stress, I'm hoping it just pushes all the crud out and makes the system more efficient, Thats going to be my marketing spchiel on the tompowerplum flusher in the Den,  |
