Power Flushing

[heating-eng]

Thanks for all your replies - confirming what I thought. No I have not paid for the powerflush. The powerflush was the first part of the work to replace a gas boiler and hot water cylinder - and not a lot went right. I don't have time to list them all, but really obvious ones were inacessible hot water cylinder drain - so inacessible that I could not tell if one was fitted at the bottom back entry into the cylinder. Then there was the flue that sloped the wrong way causing dripping outside... the problem fixed by adjusting the plume to point upwards, needless to say this did not work!

There is also a problem with the controls behaving very strangely and inconsistently, like the boiler coming on when it was switched off and I turned the room stat down .... but it does not do this consistently. Also I have had the pump starting up when I turned the hot water stat down. I have had them to look at it and they seem convinced that its the diverter valve that they are going to replace.

The guy involved is on the gas safe register.

i would report him . show them the pictures and ask them to check it

Must have only just scrapped by then.

Love the powerflush method, might have to try that one myself...

If that is how the powerflush was done, may as well not have bothered. It aint been flushed to BS:7593 and your boiler warranty will probably be null and void

gas-safe are very good if you ring them they will come and check it for you for free .

Any of you responded to my questionnaire/poll in the Gas Safe section of the forum?

I'm not an expert in this field, but I agree with the pump or pump tails connection method, anything other than this will short circuit the flow of flushing agent and leave most of the system still full of sludge.

Probably had a complete new system fitted since the original post:smile:

Yeh best to take out pump & connect there, flush hot, cold, reverse it, rubber mallet cold spots on rads, clean out F&E, re do "h" section, I can say it's always been days work for me standard sized house

 

[Geyser]

Never seen anything like that connection. Terrible. I allow a day also for a proper flush and must do five miles running around the house!

Last power flush I did took me from 9:30 am to 6pm, it had 25 radiators and I isolated each one and used a rubber mallet to clear through. Also used a water gauge to check the drain water was within 10 percent of the incoming. I connected to the pump flanges also
