Power Flushing Techniques

[hammers4spanner]

Jay What you should have done was get some PF jobs booked in B4 you spent out on a machine, that's the route I went down paid over £1200 for mine, (Kamco) Got it on my account with Plumb Centre at start of month so had 8 weeks to pay for it. A
Little forward planning is all it takes.

Do you ever get asked to do much power flush work down here?

No done 2 in 10 years, when I lived near ascot could have done 2=3 a week but never had the time but on average 3 a month, But still got my Kemco unit.

So I took the unit out to have a look and found this lovely crack in the casing to the wiring!!

This order gas been a shamble from beginning to end. Def going back!!

Was this a new unit Looks used

I got asked once last year and then they expected it for about 80 quid lol

Bet you snapped their hand off , People wont pay the cost down here + we don't seem to get the same level of contamination Proberly to do with the soft water.

If you are doing oil fired boiler installs (not sure about gas as I only did oil work) then you will get plenty of use with the power flush machine as most/all boiler manufacturers require flushing at least prior to an install.

Do the plumbers on the forums flush as a matter of course on a boiler swap like we do here?

No only a chemical clean. Flush out. Change. Flush out. Inhibitor.

 

[jtsplumbing]

PF is not a requirement , I mainly do a chemical clean, F5 in system about a week B4, Drain & Flush system, change boiler add F3 for another flush, Re fill add F1, will recommend a filter if customer wants to pay the cost, Will PF if asked for, but people always look at extra charge,

 

[SimonG]

Forgot the filter.

Always offer the flush (and most take it) prior to install. Normally do it on day one and cracked on with remedial stuff at the same time. I'm 'down here' and often get 3 or 4 full magnets worth of sludge out of the system so definitely worth doing imo.

Same here. The last company I worked for had a lot of success selling a powerflush as part of a boiler swap. I'd say 9 out of 10 customers were happy to pay for it to be done at the same time so my employer's Kamco got plenty of use.

The boiler manuals (for Grant at least, we fitted almost exclusively Grant boilers) state that the system must be cleaned thoroughly before installation and again after for warranty purposes, whilst this can mean a chemical "gravity" clean, it was not difficult to sell the benefits of a power flush, especially on older systems.

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

So do you just bung the cold feed from inside the f&e or disconnect the pipe and cap it with a stop end?
