Hi
Im after some advice please.
Had this boiler fitted around 2006-2007 and since then we have had a service plan with Worcester who do a service once a year and if it goes faulty they will come out and fix it.
Back in January I noticed that the pressure had dropped to 0 so I toped it up to around 1.5 bar and thought that was that.
Within a few hours maybe even less it was back at 0 again which clearly isnt right so I called them out and they changed the PVR, Expansion Vessle and I believe a fan I think he said it was as they were faulty/leaking
That has stopped the pressure droppping within a few hours to 0.
Unfortunalty over the period of around 7-10 days the pressure slowley drops and then ends up at 0 again.
Now I didnt really play with it to much as I dont want to mess with it to much as im no expert and when it comes to things like boilers and gas for me thats one for the professionals.
So when I saw it was at 0 I topped it up straight away but again after 7-10 days it drops.
So I called Worcester out again who came and did a few checks and said the PVR is fine and checked the pressure gague and said that was also fine.
He also said it cant be the heat exchanger as the design of this model and I quote is impossible to leak.
What I didnt realise until now was he didnt even try any taps in the house he literally just looked at the boiler.
His conclusion was that there must be a leak in the central heating system and that we should put some leak sealer in and see if that helps.
So with the help of a friend we isolated the towel rail drained out some water and added a bottle of Fernox F4 then turned it all back on and repressured the system to around 1.5 bar.
Later in that day it dropped to around 1.2 bar and thats pretty much stayed steady at that for over a week.
The last couple of days it was reading around 1 bar and again when I checked it this morning.
But all of a sudden it dropped straight down to 0.
Rather then top it straight back up I noticed that the heating for example wasnt on so I waited for that to kick back in and see if it changes and indeed it climbed back up to around 0.8.
I still havent topped the system back up yet but the other thing I have noticed is that say I run the hot tap in the kitchen after I finish the boiler sounds a bit like a toliet thats just been flushed and is refilling.
Currently its back on 0
Like I say im no expert but for me if there was a leak somewhere where it was slowly droppiing surley it wouldnt just drop from 1 to 0 after a steady week or so around 1 and then also climb back up again even if it wasnt as high as before.
Bearing that in mind surely this would be a boiler issue?
Sorry for the long post but can anyone offer some advice please.
Im quite happy to call a plumber round to investigate a leak but a lot of our pipes are underground in concrete and hard to imagine it the upstairs floors are also concrete so finding a leak if its that would be a nightmare in itself.
But I dont want to call one out if its still possibly the boiler and waste my money for no reason if that makes sense.
Thanks in advance.
