So what you're saying is, the expansion vessel air pressure COULD have dropped so much over time that water has managed to seep around the seal into the air side? Would I be right in saying then, that to test this, I could continue to press the valve, and if the seal was intact, the water...

Not according to the FAQ as you mentioned, "If water comes out when you press the central pin, you need a new PV" That seems like a pretty broad statement. Please explain how water would be where air is supposed to be in the expansion vessel without the expansion vessel being damaged...

Hello, Im back, Water immediately came out of the expansion vessel when the valve was pressed (system still pressurised to 1bar). The part number on the expansion vessel in the boiler already is 181050, I can't find this on ebay, I searched for (the model) ecomax 824/2e expansion vessel...

Just any pump such as a bike pump? According to the manual it is 0.75 bar

Hello, I have a vaillant boiler, the system is filled to approx 1bar. The filling valves are in the closed position. When the CH is on, the pressure increases relatively fast, after 15minutes it will have reached approx 80C and 2.5bar, when the CH is turned off, the pressure will return to...

How do I check/test Haha

So what should I do? I forgot the mention at the start, the boiler has been standing (not ran at all) for atleast 5/6 months.

No drippy taps from what I can see, however I will not rule it out (for now), Id imagine you'd need a very drippy tap to give the boiler the impression you need the heat to come on? (The HW symbol or whatever has not came on the display when the heat comes on unexpectedly). I'm a newbie when...

I don't recall the exact numbers but it says something like s.23 then s.24 which is ignition sequence warm start, then burner ignited. What I mean about "anything odd" is that it doesn't say s.34 for instance, aka frost protection mode. I must note, that when the boiler does come on...

Hello, I have a problem with a Valliant Ecomax 824/2E boiler. The central heating on the boiler comes on even though the timer says OFF, the timer is wired as according to the boiler manual. I've even tested its not the timers fault by unplugging the cables which would signal the boiler to...

Its a bit late along the line for knocking back to masonry I think, Should have considered it in the first place (just seemed like more work to a noob). All units etc are out, So do I PVA after bonding (before I start using multifinish?) Do I PVA again after first skim/level? How long...

Hi, I need to plaster our kitchen where half the previous skim has came off, and there are bumps from tile adhesive etc. There are also channels in the walls for cables I have made which need to be plastered over too. I have got Thistle bonding plaster and thistle multifinish plaster. I...

Thanks for all the response, It has guided me to the decision of removing the doorway (blanking the doorway off, it already had no door, was just the doorway). However inconvenient it may be (to have to walk through living room to dining room), I think the convenience of having a more...

That means carrying food through yeah, Boiler and cu are fitted and I would prefer to just put up with no door to dining room than moving one of them

If the cooker went next to the boiler, the edge of the cooker would have to be directly under the boiler, if it wasnt, then the cooker would be below the consumer unit. I cant move the sink over, as its already flush with another wall (the corner for the boiler). It is the hob of the cooker...

Indeed, To have a plug in tester show neutral as a fault in multiple sockets where an appliance works then your test equip is at fault

Hello, Half way through planning kitchen refurb and stumbled across a potential problem. There is only 1 possible place for the cooker to go (in one place it will be directly below stair case, other it will be below CU, other will be right next to boiler, other it will be right next to sink)...

Hi, there is an rccb so am okay in that aspect. So what I have proposed to do would be acceptable? Also, am I right in saying a 30a jb would suit this application. The ring is protected by a 32a breaker

Hi, I need to move an existing socket in the kitchen on a ring main. 1 cable for the ring will reach the new proposed position of the socket, but the other is coming from inaccessible boxing that goes up to the next floor which I do not want to disturb and will not reach the proposed position of...
