What if I stuck one of these in the water?

Black iron oxide has a density of 5.17g/cm3, this can hold 500g in total, meaning on average an area of 100cm3 plus a little. If system content is medium it should be ok, if however it’s on the large scale then maybe not. Remember the reservoir will still contain some that isn’t attracted to magnet. When I power flushed we used a chemical to break down any sludge and a silt free chemical to stop sludge re-binding and circulated back through system

Great, thanks. This will be the most cost effective method for me....i'll gìve it a go!

I haven’t read all posts but, how are you going to stick it in the water?

No, never.

 

[Harvest Fields]

No, never.

If I’m honest it is an art and there is a method to it.

I am guessing it will sink to the bottom of the reservoir of water in the flush machine?

I have read up about the method and am comfortable with that. I would have got a plumber in but the ones I have had in I wouldn't trust to do a thorough job, unfortunately.

How are you connecting the machine to the system? Which machine are you using?

I will use the Nostrom power flush and connect via the radiator pipes in the kitchen.

 

[Harvest Fields]

I wouldn’t connect at a rad. I would remove the pump and connect there mate.

I was going to do that but then I saw a video by Nostrom who said it was fine to connect to the rad......any particular benefit via your method?

Yes mate. You want to be attached to as big a pipework as possible. 22mm off the pump 15mm off the rad.

Thanks - this morning the boiler isn't firing up!

Does anyone know of a reliable boiler expert in the Kent area (DA14)?

A plumber came and believes 99% that the pump requires changing.

What do you think of this as a replacement:

Grundfos Alpha3 15-50/60 (130) 'A' Rated/EuP Ready Domestic Circulator with Auto Adapt 240V

I have a similar problem with the same pump. Grundfos suggested the problem was the orientation of the head. The wiring MUST be at 6 o'clock if the pipe work is horizontal - they said. In my case I think I have a blockage between the boiler and the pump as the Pw is only 10w on constant speed 3 or 5w on Autoadapt.
I have not solved my problem yet, but does this orientation point make any sense?
