Been to a job today to have a look at a leak on an Ultracom 2 30CXI. It was leaking very slightly from the diverter valve spindle and also the AAV. Glow Worm Group Service have already been out to look at the boiler.
They claim to have drained some of the water into a small jar and left it on site. The water had a brown tinge to it with some settled sediment at the bottom. I drained a little bit of water out the boiler and it was clean. Very clean. Boiler was installed by BG December 2011, has a filter fitted on the return and the commissioning book says X300 and X100 used.
So I rang GW again, they said it needed flushing before they would do any work (code 3) as the system was 'really dirty' and the Fernox test said 0.015 or something like that (sounded like BS to me). So I have today drained the system and flushed it through with some Fernox F3 cleaner and added some Fernox F1 inhibitor. The system was possibly one of the cleanest I've drained. Water was clean as anything. I've now booked it back in for them to attend and actually do the job.
So just watch out these guys must be getting some water off the van to get out of doing the job. I just can't see what was in the jar being out that system. Surely on a system 18 months old, the boiler should be able to withstand a small amount of debris from new rads. If the system needs to be spotlessly clean for a seal on a diverter valve to not leak then to me the boiler is not fit for purpose IMO.
