Just a quick message to say that I fitted the Jass Ferry pump after all and it's still going strong nearly 3 years later. Thought this might be useful for anyone thinking of buying one.

Hi JohnD, Will this still help to free the sludge? Is the cleaner not more effective at higher heat levels to dislodge the sludge? Cheers

Well I spent ages cleaning the pump yesterday and when I re-fitted it, it kept tripping the RCD, so massive DIY success from me there! I think I probably got some of the electrics wet, like an idiot. In a calculated, prolonged fit of rage, I went ahead and fitted the new pump which annoyed me...

Thanks for all the replies. I wanted to change the pump because it is noisy as hell. I imagine this was because it was constantly trying to work through all the ****e running through the pipes. @ianmcd thanks for the technical advice regarding the X800. I rang the technical line at Sentinel...

I'm now also thinking about giving the system a quick blast of Sentinel X800 befor I fit the new pump but as above, do people think it's worth it considering the rads are all working again? The only reason I'd be doing it is to preserve the new pump. I'm hoping to get this sorted today so would...

Ahh, your way sounds like a much better method. I just followed the instructions on the Sentinel website, keeping the X400 in for a week, running it for 3 hours initially and then putting on the heating for a couple of hours each week: "Sentinel X400 should be circulated, preferably at normal...

Evening all, I've recently cleaned my F&E, microbore central heating system using Sentinel X400 and this led to the cold rads heating up again, so a success in that respect. Now, after a week of the X400 circulating, today I cleaned the F&E tank again (much cleaner water), drained down the...

All fantastic responses which have contributed to both my learning and my peace of mind, thank you all very much!

Hello all, My new house has a Baxi EcoBlue Heat Only boiler (pictured), complete with a hot water cylinder, an F&E tank and two cold water tanks in the loft. I've run into problems with cold radiators recently and managed to sort it by running Sentinel X400 through the system. Having had to...

Thank you for the detailed response, it make much more sense now! I've already cleaned out the F&E tank and am currently circulating Sentinel X400 cleaner around the system, which has sorted the issues with the cold rads (it's an annoying microbore system which I think had got clogged up). After...

Thanks for the quick reply; i'd already looked at those DAB ones and now i'm more re-assured about buying one. I noticed the link you provided says "Install with motor shaft horizontal". Apologies for the silly question but isn't my Grundfos one currently installed vertically? Also just out of...

Hello all, I may have to get my central heating pump changed as it is making an almighty rattle all the time* but I am not sure which one to get. The pump I have currently got is labelled 'Grundfos Selectric 4', Type 4 -50/130 (please see pictures attached) and has 4 speed settings. Is there an...

Thank you all for your replies. Yes, he is Gas Safe registered and I watched him test the work he did. He seemed a little confused about why it had started to leak and asked my brother or his kids had touched the pipe, which they hadn't. Anyway, i'll get some Denso tape and get the job finished...

Hello all, Hopefully this will be a simple one! I'm trying to fix this 68mm round guttering (see pic) but i'm a complete novice and rubbish with angles. Currently the downpipe is just loosely pushed into the gutter fitting above and resting on the stone below. I'm presuming it should be fixed...

Hello all, My brother has just had a new boiler fitted and the gas engineer routed a new copper pipe directly from the meter to the new boiler. The old copper pipe that fed the previous boiler came from under the concrete floor, where it tees off to feed the gas supply for the cooker. Although...
