Thank you guys. Got a plumber round and he was saying to have it fitted under the bath where only the bath water will be pressurised. As there is no electrical socket in the bathroom, he was suggesting to drill a hole into the wall and have the wire leading to the next room and plug it into a...

I can see the two pipes for the heat exchanger. I can see the pipe that goes into the bottom from the cold water tank. I am assuming the hot water out would be somewhere on the top? Which still leaves my question of the pump unanswered. Can the impeller or bearing be damaged if there is...

Do I have to use both sides? By only using one side for the hot water damage the pump? I have looked at my hot water tank and cant seem to figure out where to make the cut to fit the pump. Can someone guide me. Please find picture below: http://oi41.tinypic.com/1642s7.jpg

Many thanks for all your help! Does it matter which pair go to the hot and which pair got to the cold? How can I tell which is the inlet and which is the outlet?

Thanks! So shall I replace all the grey bits with new JG Speedfits and do I need the inserts if my pipes are copper? Also what can I use as a rubber base and can it be purchased separately?

I bought a secondhand shower pump which I assumed came with all the fittings. Looking at it, some of the connector attachments are missing (see below). https://www.dropbox.com/s/h74ephbgbgw3543/2013-12-07%2010.25.23.jpg Is there a way I can get these from somewhere or what are the other...

Told the missus to observe it but she keeps forgetting. Nevertheless it has behaved since. You were right though about pressurising the vessel first as the way I done it, the gauge would reach around 2.5 bars and would fluctuate quite a bit. Done it the way you adviced and now the gauge does not...

Hi Mandate, thanks but it seems to have done the trick. Have been observing it for 2 days but point taken about the volume of air side. The only reason why I did this was because by filling up the vessel, to 0.6 bars, I have been able to bleed the system via the PRV. Now I know this is not the...

ratonnastick, thanks but I am really beginning to think that the pressure loss is owing to either the expansion vessel or the PRV as after misterdubya and Mandate mentioned it, it jogged my memory that the pressure loss started happening after I touced the PRV. It does seem like a coincidence...

Any tips on the best way to check if the diaphragm on the Expansion Vessels blown? Can I not just stick a pin in the tyre valve and see if water comes out through there?

Hey guys, thanks for the reply. Yes it does make sense now. I'll check the PRV in the morning and post an update.

Sombody? Anybody? :)

Hi, my boiler has behaved absolutely well for the last year. So the other day, switched it on and shock shock horror horror, the pilot would not come on. The boiler and fan light was on. I am extremely DIY competant and see a boiler much like car engines and heater systems without the gas of...

Nearly forgot to post... it was the C/H pump.

The pressure is at 1.1 bars now and it has stopped leaking. I'm suprised that the HE is an RGI job as it is totally independant from any gas work. Development. Boiler did come on again by the way and now the overheat light is on again. The boiler took over half hour to come on after the last...

Yeah thats what I would have thought. Anyways, this is where I am... took the case off, the joints connecting to the HE is fine and not wet or anything. Removed the cover that exposes the HE and you can see that is it slightly moist. However, the water has now slowed done and is easier to see...

I did the most stupidest thing tonight. Boiler was shutting down and overheating light kept coming up, So I bleed all the radiators. It still kept doing it and I could hear gurgling in the pipes near the boiler so I opened up the fill loop and started bleeding through the pressure relief valve...
