Cold feed blockage

[megancsaunderson]

Hi all,

Quick one (I hope). I have a gravity fed heating system with a glow worm flexicom boiler in the kitchen. A tank in the airing cupboard with a Grundfos Alpha 2 pump.

For the last month or so I've had lukewarm water and no heating, have been taking advantage of the immersion but my electric bill has been through the roof since so I needed to get someone round to take a look and it appears there is a blockage in the cold feed which explains why the pump has been making a strange sound, like a whooshing sound, not a steady flow by any means.

I am wondering how easy a fix this usually is? I know this is a job that varies as there's no saying how much it's blocked by etc but I am a novis with regards to these sorts of things and wondered if this is usually an expensive job, if there's anything I can do myself...

Thanks for your patience

I supposed it depends on how big the blockage is, either way if it is a blockage it’s usually a re-pipe.

Please confirm what you mean by the cold feed. It's a technical term and I want to check you don't mean something else.
