To Powerflush or not to Powerflush

[sharonjones2]

Hi, our downstairs radiators act as U pipes (pipes come down from upstairs, then back up on other side of radiator) and are constantly filling up with black sludge - we've been advised to powerflush, but also warned about the risk of pin point leaks...don't really want to spend £400 odd on a powerflush, but worried that if we try adding the chemicals ourselves we're going to get the leaks. Any advice?
Also, would it only be the radiators that would leak, or would the pipework (copper?) leak too? Thanks!

from my understanding (I m not a plumber or heating engineer, but i read the forums) it will be the rads that will leek, since they rust from the inside out.

copper does not rust so no problem there unless a bad joint gets blown apart (unlikely)

unfortunately only a powerflush can clean it properly .

A chemical flush (diy) will not remove all of the problems .

If you do get a pin point leak atleast you will have an expert at hand to sort it out if you have a power flush.

You can hire a powerflush pump with all necessary hoses, connections and chemicals from Travis Perkins for £60 a week.
It comes with all instructions and is a very simple process to do.
As for pin leaks, if you have so much sludge your rads will rot beneath it in any case (it settles and sets hard which is why you need to powerflush) if they are rotting then regardless of what you do you have a problem waiting for you.
New rads are readily available from many sources and you can usually pop one off and replace it quite quickly.
Otherwise shell out your £400 (I was quoted £580 from British Gas - taking the mick eh) you'll still have to sort leaking rads if they do leak.

I wouldn't be sexist though there are women plumbers I've seen......

when done correctly a powerflush will sovle many central heating problems but i would also advise fitting a magnaclean filter as well to keep the sludge down.
