powerflushing microbore

[gas1]

hi do you think i could pre treat with kamco fx2 for 24 hours before power flush to speed things up or is this acid based chemical to strong?
have already tryed neutral cleaner but has left lots of scale on system visible on magnaclean twintech clear filter

thanks mark

i think kamco say to use hyperflush in the system before hand beacause i think your right its too acidic

wouldn't leave an acid based cleaner in a system...not even for 24hrs,acid will attack the metals in the system....could cause more probs than solving. are you using a inline magnetic filter within your powerflush setup?

 

[danielp]

dont forget to use your ph paper and your turbidity tube and your rad drill hammer that if you have got rusty rads will go straight through them !

ok that was what i thought really will not pretreat,i have a norstrom magmaster with integral magnet filter that works realy well on magnatight, it is just this scale i need to disove and remove first flush was with sentinal x800 but it did not touch the scale

When I did the Fernox powerflushing course they told me that powerflushing microbore can cause more probs than it solves

The biggest problem is with the old twin entry one sided valves as you can never flush every bit of cleanser out of the system.

the pipework is classed as microbore but it has 22mm main feed and reture pipes with 10mm tails to either side of rads, it still reduces flow alot throu powerflusher

piggin nightmare
did one the other day took 2 hours to clear the upstairs rad
rad wasnt the problem it was the f/r in micro back to the manifold
when quoting quote extra to take into account the possibility of a major blockage thats tough to clear in the 10mm tees of the manifold

Did a microbore system last week 2 rads not heating up. Flushed rads then had floor up and it was a combined manifold, ran new connections flow/return and capped existing 8mm, couldn't touch the rads after that. Job sorted.

Hello Gas1.

If you think that the problem you are faced with is so bad that you need to put in FX2 (which is the best 'hard' cleaner around) then, personally, I would prepare the customer for the worst possible outcome and be prepared for more work.

That's just my opinion of course. We've had a few microbore jobs that on the surface looked straightfoward and turned out to be a pig. Out of many successful ones.

To protect yourself in a court of law I would imagine that you must read Kamcos instructions and follow them - just in case. However, I would be happy to leave it in my system (Vaillant boiler, 15mm copper pipes and steel rads) overnight. And add neutraliser after the clean

I have no aluminium and lots of time, water and neutraliser for my own system.

GAs1, do you refuse to powerflush 8mm unless you can clean out the rads outside first? Does anyone else?

I wouldn't worry about putting a hole in a rad with a vibrating pad. Has anyone actually put a hole in any kind of rad using a vibrating pad? The first time I used one a badly installed 15mm pipe popped out of a lockshield but blasting a hole in a rad with one?

I for one would love to hear about it. There are a few myths around that get in the way of the truth about powerflushing. People need to know if that is happening and why.

Gas1, please forgive the soapbox and all the best whatever you decide to do.
