Power Flush...

[AlexGas]

I use Power Flush FX2 and the crystals to clean the CH pipe work. I find that it takes ages to get the dump water clear. It took me less than 20 min to do the job by using mains cold water pushing all the dirty water out. 2-3 min per rad, job’s done. OK, it’s a bit of waste of water… What are your thoughts on this one? Does anyone else has the same procedure?
Here the set up I had:

I think you need a quick revision of water regs re contaminating the mains supply!!!!!!!!!

 

[AlexGas]

Double check valve!

 

[lame plumber]

like i said have a read of the wras regs

 

[AlexGas]

OK, bad idea, I'll stick to plan A.

I've got gallons on Fernox F5 in the garage if you want to try??

Thank you, I like using the acid.

By the way, a boiler in this house was off for the last 2 years. Dead. How about that!?

No, in the right circumstances a mains flush is a good option. Just stick a double-check valve into your rig so you can't get any backflow from the CH system into mains.

As for how good it is compared to a full flush with FX2, in my experience mains flush will only wash out loose debris. For hard, caked-on magnetite, chemicals, preferably with heat and agitation do a much more thorough job.

Horses for courses. Understand all the techniques approved in BS7593:2006 and apply according to your judgement.

If you haven't done so, download the instructions from Kamco's website or go on their training. You basically do a mains flush through the machine before you start the chemical flush anyway!

Defo! I love my magnetite.

I don't think on boiler changes customers expect to pay for extra time for power flushes

I always include one in the quote. But then I very rarely do boiler changes in one day.

Some dudes do try to do it in a day, though! Not me.

Im not interested in blasting through them anymore getting old plus just think it looks better to customer if you take your time.

 

[AlexGas]

I always use Kamco machine with magnetite set up. All I wanted is to speed up the final dump.

A magnacleanse in series with your power flusher, cuts loads of time

Does anyone do the dreaded - Take each rad off & flush them outside with the mains & a garden hose? Then, flush the pipes as OP?
I used Fernox F5 on a job & left it in full period. Then went back & lifted all rads off & hosed them out. I honesty don't think a power flusher would have removed the dirt as well. 3bar mains into bottom of empty rad & also turning the rad over a few times with some water in it seems to clean it well.

Nope, not me.

Go on! Be brave! :smile:
Honestly, - on some houses removing rads method is quicker than proper power flush I bet. Certainly no slower from what I see. I also reckon if after some power flushing is done and a rad is removed, there will be crud still in it.

Just invest in a Power flush kit.

Bugger that.. I imagine black sludge spurting out over walls & carpets plus it gives me a bad back just thinking about the concept!!

I have a basic power flush machine sitting ready to use, but it's gathering dust! I don't use it as it doesn't do a great job.

Depends on the house, - if it is all white carpets etc, then I would be wary to lift rads off. But if it's mainly tiled or wood floors, then no worries.
Sure you can drain the system first, then put plugs on rad rails if it is too risky.
Does really need two people to lift rads off, although I have done a few by myself. Must admit it's not worth a sore back!
