Power flushing costs

He was on about unsoldered (it got forgotten probably) ancient pipework. I have given a practical example that this does occur having found one only last week. The fact that it wasn't on CH pipework isn't relevant.

What he might have meant (only he knows) is that what would happen if a joint such as this exisited on a CH system and which the ordinary circulator didn't cause to leak but that a powerflush machine might. I think.

Guess you havent done many powerflushing jobs keystone ??

You'd be right because I prefer more old fashioned methods. Nevertheless I don't know how you derive that conclusion from my post or was it just guesswork? Go on then educate me please. What is the a difference in pressure and flow rate between a power flush machine at max chat and a domestic circulator? Has a power flush machine ever caused a joint previously thought to be OK to fail because of that difference?

All I can say is that I have done hundreds of power flushes over the years.
I also worked for a company that has done thousands of power flushing job.
I have never once had any joint blow, never once. I have only had one radiator leak in all that time.
I am not aware of any of the jobs from the company I worked for that has had a joint blow.
So can it happen ? Well maybe but in my opinion it is very unlikely.
Would be more helpful if the people that replied to these threads had some experience in what they are talking about, instead of confusing people.

Good for you.

Thank you that answered one question. How about the pressure / flow rate one. As I said I don't actually know what he meant.

Thank you for your experienced opinion.

I would agree entirely. For example I know that a power flush has no chance of shifting a solid magnetite build up nor will it shift a solid mass of sludge in the bottom of a rad. As I said nea the top of the thread mechanical means are needed in my experience.

if you look at my post history you will see that i only comment on things i know about..:D
you replying to a post about powerflushing when you have never even done a powerflush seems strange to me. are you just trying to get your posts up ?

Oh what a shame - you were doing really rather well but now have gone and spoiled it.

there is alot of bickering & BS floating about on this subject, i have been running a plumbing & heating co in southampton since 1982 & i have done alot of powerflushing jobs, from my experience BG charge on average £600+ & don't do a very good job of it (ie i did one today on a system that BG fitted a new boiler, pump, mid pos valve & pump 5 years ago & it didnt look to me if they had flushed it at all), i charge on average £300.

Is it worth doing ? well that depends on each situation but it will generally make your boiler & pump last longer if done correctly but of course that will also depend on your heating system & pipework being installed correctly in the first place (& you would be surprised at the amount of systems that aren't fitted correctly).

most new boiler manifacturers insist that the system is flushed before fitting or it may invalidate the guarentee

A chemical flush not a powerflush is required by Vaillant, Viessmann, Worcester Bosch to maintain the warranty.....customer's choice.;)

here we go again read my post i said flush not a powerflush, but have you ever tried to manually flush a heating system ??

1 it doesn't work very well as you can't get all the sludge out
2 the time taken to empty & re-fill time after time it would be cheaper & better to powerflush
