When you guys powerflush where do you connect the flusher on a combi boiler?

I've always connected to rad tails, made perfect sense. Just watched a video though saying its better to tee off by boiler so you flush the pipework leading up to the first rad. Most of the time though combi is in the kitchen and the first rad is couple of metres away, is it worth the hassle of cutting in tees below the boiler just to flush few metres of pipe? or is he trying to justify the higher price he charges for his flushing?

The bit he says about not being able to flush individual rads unless you flush from boiler is complete bs though

I often do as you do cos its easy, I also cut in tees but I think many connect to the pump tails

Way I see it, you're either flushing the entire system or you're not! Not so bad on a combi swap, but think of that last return run up to an old Kingfisher or similar, Normally gunged right up!
 
Take the pump head off and use an adaptor. It gets all the pipework and the plate heat exchanger without having to take it out.
 
With a powerflush they are getting a filter as well. Fit the filter first and then connect machine via this.

You take the pump head off on a combi? Bit dangerous aint it?

Awfully close to the pcb!

The pump head adaptor comes with good thick O-rings, plus I have a selection that I've taken out of old pumps. I also have a selection of different length Allen bolts. Very rare to get a drip, and if you do, just stop the flush and sort it before continuing. Or you can slip a bin bag over the PCB housing and tape it up.

I've always done mine through the pump head, use the Kamco pump head adaptor and seals and you're away. Never had a problem.

If we are talking about a combi & you go through the pump you are flushing through the boiler & HE, do you really want to be putting the contents of a dirty system through them ?

It might give you a line size connection via the pump but what about the filter, built-in by-pass & all that high quality rubber tubing in them now days ?

And those that are flushing through a rad cons (I bet you don't even take the valves off) so you might have a nice big flushing pump but it is trying to push through a <10mm opening, you are just not going to achieve the velocities needed to clean the 22 or 28mm main F&Rs through a 15mm let along the valves.

Have you ever cut out sections after flushing to see if you have actually done the job you have claimed (& been paid) to do?

Last up, I listened to it right the way through & I don't believe he ever claimed that you can't flush individual rads unless you flush from boiler.

I use the boiler as I can heat all the rads up and make sure that the heat exchanger will get cleaned out as well. If the boiler is dead then the Kamco immersion gets switched on. Power flush magnet collects a lot of the muck anyway, never had a problem myself. How do you do it? Someone mentioned a great idea of linking the cold feed and open vent on a gravity system the other day, previously I'd just capped them
 
Southern Powerflushing do a great job and their prices are very fair. If you have any questions about powerflushing you can call them for free.

They also hire contractors across the south east of England (I work for them currently) good pay!

Www.southernpowerflushing.com

Power flush, power flush radiators, central heating cleaning, boiler powerflush
 
I find it funny they allow the same time for upto 10 rads as they do for 21+ good luck doing 21+ rads in a day

Yeah, true. They do say the allow up to 3 days per job. The booking system just books in one contractor per day (so they don't overwork/over assign us)

You can only do one a day anyway well properly
 
I use a magnacleanse rather than a traditional flusher. That way a combi can be flushed through completely using its own pump.

If you flush through the combi you let it run ? If so, you will feck the pump one day because if you change the direction of the pump then you got 2 pumps working against each other.

I don't think it's good to flush through and will not do it in the future. To push all the mick through the heat exchanger etc don't think it's the right way. I'd rather would flush the heat exchanger seperatly. Someone told me recently he flushes with the biller running in low speed but just in one direction because of the pump. But as mentioned I would not do it will be too expensive if something goes wrong

He doesn't use a power flusher just the mag unit

I know, I was just general speaking, I don't even know why it quoted. However, i didn't want to comment on him particular just comment on to the subject

You certainly wouldn't flush the old combis with diaphragm diverters. I use a magna cleanse because it uses the boilers own pump and also there's no changing direction.

Does it help? How long do you flush it through ?
 
For anyone who doesn't know

Isn't a wind up just wondering as I do not flush through boilers at all.
Click to expand...

yes you do, as ive had the same conversation with you remember you trying the flush the boiler and pipework with the boiler valves closed, you were wondering why there was no flow through the mag unit

and i guess you dont use the mag unit to attach your flushing equipment

No i don't !!!!

And yes boiler valves are shut because I don't want to flush through the boiler. It ain't good. I always attach my mag unit ... how do you know how I work mate?

Because you phoned me up and asked me why it wasn't flowing and if you attach it to the filter you can't do it any other way (than going through the boiler)
 
I have to question qualifications here. Are you trained?

If I do a power flush I do t need to flush through the boiler it will work without it
