No Central Heating, Pump faulty???

[Wrighty8]

Hi all,

Central heating has packed up at my parents house, firstly it was only the upstairs Rads that were working and downstairs not now both have stopped working.

I think it could be the central heating water pump as it seems a little loud with some 'odd' sounds now and then, I have tried tapping it with a hammer and it did work for a day or two then nothing.

The pump is under the living room floor so quite awkward access, not sure of the model but I did see an empty box (may not be the current pump) saying Gold 30 or 50 on it.

Do you think a pump change will solve this and will any pump fit?

Many thanks.

Pump common to loose downstairs first

It does sound feasible to be the pump. Measure across, should be 130mm, and note the head, so will probably be a 5m.

Thanks for the replies.

Going to take the pump out first and take a look and manually move the impeller to see if that helps but will order a new one for them.

Update.

I've just had a call from my Mum and it's come on! up and downstairs all working - it's set on a timer for 2130.

99% sure it's the pump now as I only took a hammer to it yesterday and gave it a few whacks.

Failed again! Lasted all of one day/night!

Here is the pump that's installed currently, there also was an empty box under the floor boards of a Wilo Gold 50!

Is the current pump any good? What can I replace it with?


Thanks.

You tried screwfix that wilo should be ok

If the old pump was a 5M then the Wilo is fine, if a 6M, go for the Wilo Yonos Pico 6M.

I think the old pump is a 5M, the old old pump was 5M as the Plumber left the empty box under the floorboards.

@ShaunCorbs, yes oos near me.
