No car stuff done as the boiler is demanding my attention this week
It's had a weep (ok a bit more than that!) from both the main exchanger outlet and the pressure switch for a good while - although the exchanger leak had largely sealed itself. This week it got substantially worse, and with the cover off water was pouring out of the exchanger outlet. Now, this is a copper pipe into a plastic housing, sealed with a O-ring, and my plumber friend thought the o ring had gone (sounds familiar....) and got one ages ago, but we never around to fitting it. He's away of course this weekend... Anyway, got it apart and managed to get a new ring from the plumbers merchant (£3.41 for a 22mm O ring

). The pressure switch is also plastic, and screwed in - despite having a new switch, I had put off installing it, as I strongly suspected it was going to shear off as soon as I went near it. I was not disappointed

Went and bought a set of easy outs, but wouldn't play (later turns out I was just screwing the easy out into the back of the brass housing

) So I drilled it a bit, then spent about 90 mins cutting / scraping out the remains of the old one until I could screw the new one in. New O-ring on, put it back together, filled with water, and...... no real change

A closer look at the outlet housing shows that in fact it is cracked, and given that it doesn't appear that the housing is available separately, and a new exchanger costs half as much as a boiler, looks like it is new boiler time. Of course they always pick the cold times to give out, don't they

There's still time for having a go at a bodge though

I think that a well aimed piece of alu plate, some RTV silicon, and a jubilee clip, may effect a 'temporary' repair to give us some breathing space before fitting a new boiler.
On the up side, the PTFE repair on the dishwasher is holding, and the boot handle for the Pic has arrived.
Off on an emergency call to a friend's with a new baby to look at their heating now
