Partially blocked microbore C/H

[DealorNoDeal]

Therein lies another problem.

The muppet who installed the C/H used very long lengths of microbore. (It's usually recommended, with microbore, that you don't have radiators more than a couple of metres from a manifold.) One of our radiators is so far from the manifold, it takes about 1/2 hour to heat up.

The blocked radiator is about 10m from the manifold with what I'm guessing are quite a few elbow joints inbetween. It might be possible to rod the pipe but it wouldn't be easy.

Any suggestions of things to try?

Have you asked your accountant?

Have you asked your accountant?

You mean the one who installed the C/H?

If you were thinking of moving house, now might be a good time to consider it.

Yes, and moving house would probably be less disruptive than replacing all the crappy microbore. Most of it is downstairs and buried in the concrete slab.

I took some syrup of figs and I'm fine now.

Sorted

I cobbled together a connector so I could attach a car foot pump to the flow pipe.

It was a bit squeaky bum as I increased the pressure higher and higher but the blockage finally gave way at 5 bar (70 psi).

So next question - how do you fix things so it doesn't occur again?

Short of replacing all the microbore with 15mm...

It's probably worth shoving some cleaner in now and again, and making sure the system is always well dosed with inhibitor. I think there are also some filter devices you can install which are supposed to trap sludge.

Yep, magnetic filters. Well worth fitting in your case as they will catch the rust particles and sludge from the radiators so you can periodically remove and clean them. I'd remove the radiators in turn, flushing them out to remove the worst of the crap before refitting. Flush the system as thoroughly as you can to clear the pipes afterwards, then run cleaner through it and fit the filters. Run the heating for a while every day to begin with to encourage the remaining muck to circulate and the filter to catch it on the way past.
