Any tips for changing a central heating pump?

FFS get a fooking plumber.
If you try it you'll only piss your pants when you cock it up and then multiple dull threads will sprout up about your fooking plumbing.

WE ARE NOT FOOKING INTERESTED IN THE LEAST, GEDDIT.

WHS - Listen to Ricky Gervais explaining it to Karl Pilkington (30s in) and heed his advice.

You're a contractor. Get someone in to do it, FFS.

It is the duty of the wealthy man
To give employment to the artisan.

He deserves the rest of the quote:

Lord Finchley tried to mend the Electric Light
Himself. It struck him dead: And serve him right!
It is the business of the wealthy man
To give employment to the artisan.

In all seriousness, when you have changed the pump you should dose up the system with Fernox or similar central heating system treatment. You will be amazed at the difference it makes to the system, it will be quieter and will stop corrosion in the radiators and pipes. It will also make the pump run much quieter for longer. It is amazing stuff, really.

Dont use Fernox if you have a primatic tank.

I'd bought some and was about to put it in the system until I read up on the type of tank we have.

Fitted the new pump it around 30 minutes.

Then the bottom gate valve started leaking. It was one of those crappy isolation valves



So then it took 2.5 hrs to remove the pump, isolation valve, cut off the old olive, fit one of these



and put it back together again.

Thanks suity, was having similar problems but managed to keep the ego intact and fix it myself without the intervention of some knob jockey quoting me a three figure sum for a couple of hours work.

And my plumbers toolbox has a nice shiny new set of pump pliers. Plus if I ever need to change a pump again I know spot bollock what I'm talking about.

Time to celebrate with some guinness, whiskey and take away curry.

Edit : Getting nippy, better put the central heating on. :smuggety-smug-smiley:

I had a plumber out three years ago round Christmas time to look at a failed pump. He sucked mightily through his teeth and said they didn't do those pumps anymore and I would probably need a whole new heating system. He said that luckily he had a reconditioned pump from an old system and would fit it for £80 - I was in a tight spot so agreed. It failed about 6 months later.

After that one failed, I went to B&Q and found a replacement one. Bloody loads to choose from on the shelf. I was pissed off that the plumber lied and even more pissed off that I was stupid enough to believe him. Fitted it myself in about an hour - 40 minutes of that was looking for the right tools. Twas easier than fitting memory in a computer. Still working today and better than it ever has been.

Robbing tradesmen. Grrrr!
