Power Flushing Techniques

Kamco sell the neautriliser

I've done a power flush on every boiler I've installed, the amount of muck I've pulled out of systems is unreal. The Kamco magnet works a treat.

I do the following:

Open vent system
Isolate cold water supply to f and e
Drain out f and e tank and cap the feed pipe and open vent
Set up power flush and connect to pump
Open all rad valves and with the pump set to dump I switch it on and the initial muck gets removed from system.
Set pump to recirculate and let it heat up, add chemical, either FX2 for cast iron heat exchanger or Sentinel X800
Let everything circulate and then close off all rads/hot water coil apart from one.
Flush that one rad until evenly hot all over and use a rubber mallet for persuasion if need be
Move on to each rad like this and then open coil to flush again
Then, start dumping and rinsing with fresh water only on just the pipes
Then go to each rad one by one and flush with clean water until water runs clear
Open whole system for final rinse
Add neutraliser if required and flush accordingly
Add inhibitor
Job done
Depending on size of house can take between 3-6 hours

Couple of questions: (sorry if they're stupid)

What do you connect to to fill up the system if you've disconnected the f&e?

When you say, set it up to recirculate and let it heat up, are you running the boiler while doing this or do you have one of those heater attachments?

Let's say its a 3 floor property, do you do one floor at a time?

Also, let's say its a 3 floor property and you've connected to via the pump head on the ground floor and you want to flush upper floors, once you've dumped and refill, won't it fill up the flush machine before it reaches the upper level rads??

I'm gonna do the kamco course as soon as I can but these are questions that are bugging me at the mo

Fill through flushing machine.
I use the boiler, all mine are oil boilers.
Depends on the power of the pump on the flushing machine.
Only have a problem if you turn it off. I have my machine in an extra large gorilla tub which catches the overspill.

Do you guys do pH and TDS measurements?

 

[macackau]

I run the boiler to warm system but have an immersion element to warm up if the boiler is dead

I do a rad at a time so floor by floor is sort of followed as i just do the rads one by one

The machine is dumping the water you add so you're not losing water from the system and yes I test PH and TDS

Where do you live, if your local I'll show you how i flush if you like?

Not far then, 11 miles only snag is, I work for a firm mon-fri.. Do you do work saturdays?

 

[macackau]

Not usually. More than happy to sort out a flush at my place one Saturday though to show you what I do. My system is sealed but will show you what needs doing anyway.
