Flushing a micro-bore system with British Gas or Npower

[smoggs03]

i'm an installer so have nothing at all to do with repairs/services.. the usual route is to advise a new boiler which will fix everything, in which case i turn up fit new boiler and .........hey presto 4k all works leaving me to fix a cruddy system as well!!!! but 1200 can't work that out and i have price lists??? can only assume each rad needed hand flushing so labour charge x2 but fully qualified engineers??? dunno quessing

Good call smoggs, unusual to have 2 x blokes on the job so there were extenuating circumstances for sure. If I visit 8 x properties in a day, at least half would have sludge. Why don't installers insist on powerflushing before installing new boilers? I don't know if it is workable but I'm considering it wen I decide to go it alone - is it feasable?

In my experience you need 2 guys to powerflush properly. Each rad needs to be flushed and reverse flushed individually and if there's more than 12 rads in a system you'll be working all day. I've yet to find a system i've flushed that doesn't have a couple of leaking lockshield valves that require changing. Powerflushing before installing a new boiler or before commissioning makes sense. I do warranty work for one of the largest oil boiler manufacturers in the UK and I've lost count of the expansion vessels i've changed that are full of black iron oxide due to an installer not flushing correctly. For a dirty system you can't beat a powerflush as long as it's carried out correctly. Sitting in a van for hours reading your paper while the machine flushes is NOT the correct way to flush. I'm sure you'll agree.

Kip, CO Detectors are NOT a pitch, they are best advice which is an industry thing not just BG. The other stuff ...you could have a point, that's the pressure we are all up against. Drop the hang up about BG engineers tho, we use the site too, ppl who fire snidey shots from the comfort of this place **** me off (touche), you should have told him there and then mateand debated it in front of the customer.
