  1. Ah, one of my fave jobs working for the gas board, fixing the problems after the DIYers bugger up their systems, or the standby call at 7pm when the water is pouring through the ceiling after the bleed plug is removed from a radiator! Enjoy!
  2. That is generaly what I do as part of a powerflush, obviously I only carry out remedial work as required, but I will generaly replace the pump & pump valves as part of the job. I always combine cold feed & expansion pipes if possible (on open vented systems) as we try to eliminate the chance of needing a re-flush. Fitting a Magnaclean is the way forward too in my opinion, I recomend any engineers working for themselves to start fitting them! Also, I didnt mean to tar everyone with the same brush, I realise there are some good firms out there who also do give a good service, just watch out what you are getting for your money! P.S. dont all engineers love getting numerous cups of tea? I do!!!
  3. I think some people on here are getting a bit carried away with their 'expertise'! I am a BG engineer, and indeed an engineer who carries out powerflushing on a regular basis (everyday just now!) Ideas like 'just turning your pump up a notch' and 'I bled the radiators and now we dont need a new boiler' are complete rubbish! When a system is drawing air in and needing bled regularly, a powerflush will temporarily cure the problem, however, when we carry this work out we will normally cut & clear system blockages (normally occuring in the cold beed pipe where hot & cold water meets), combine the cold feed & expansion pipes if possible (open vented systems) only if the appliance has an overheat protection device. We will also balance the system and set the correct pump speed. In most cases the pump, and and valves (pump, motorised or manual) will be replaced. Twin entry radiator valves (valves with one valve & 2 pipes) require to be split & replaced with a valve either side of the radiator before a powerflush can be done, as there is a small tube which circulates the water attatched to these which can become dislodged during a flush. If you have had a powerflush but still have twin entry valves, chances are the system hasn't been flushed correctly. We now use a magnaclean filter (a strong magnetic filter) incorporated into our powerflush machines to extract any iron oxide in the radiators & pipework. We can supply & install a permanent magnaclean filter to any system at additional cost. I read that one user reckons 4 hrs is a good time to powerflush a system, BG powerflush (including remedial work to rectify faults) is normally done in around 8 hrs and priced accordingly. Our price includes all parts (irrespective of cost) and labour. The powerflush lifetime guarantee was only introduced in 2004 (I think) but we will do a re-flush if needed as long as the same customer owns the property. Any radiators which corrode badly and leak will be replaced if a powerflush has been carried out. Our average price is around £600, and we use fixed price quotations (subject to region) but if the powerflush is done correctly it IS good value for money when you look at the work we do. Lets see if your £250 flush gets you anywhere near a service like that, I'd think not.
