When I changed mine I simply isolated the boiler from the water system and radiators , then release the water pressure in the boiler. Nice video, well explained.
wouldnt recomend that on older boilers the valves can leak then you have 2 problems to fix but baxi 105 s have a drain off on the boiler dont know why he didnt just use that
What about draining the rads if you live in ground floor flat ..my pump is fine..its the manifold its attached to thats leaking from the top highest point out the plastic valve .
Haha I'm not a plumber or gas engineer and even i know u just needed to drain this boiler. FROM on the Boiler mmmm. This boiler has a drain valve on the right hand side behind the cover. Stick a small tube or straw on and drain lol
totally agree!!!! Not only that, his initial information is WRONG!!!!!!! The manual doe NOT say the pump is bad, it says "pump fault or low pressure". Most common problem is the pressure switch on the diverter valve.
@@tonyPOPhowes Will re-pressurising the water system get the whole thing working again - hot water and heating, do you think? I've got a very low pressure reading on this same boiler model with no heating or hot water.
@@SunOnMyStubble the radiator system needs pressure (needle in the green area), so if that is low it'll stop the heating coming on. Google diverter valve!!!, there is a micro switch on the back of it that is pushed by a pin coming up when heat is asked for. If it doesn't come up then sometimes wd40 can help lube the pin to rise up. Also you could depressurise system and take out 15mm nut to clean/grease. Or worse case, the diaphragm has a whole in it. No biggy to fix if you're handy. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xMOV0wohopM.html not my video but handy information
@@tonyPOPhowes Thanks for your reply. I fixed the boiler when it leaked last year (replaced the diaphragm, very simple) so, hopefully, this shouldn't be too hard.
