I have decided to go for a new UNVENTED system to replace the faulty Vented Combination Cylinder. Can anyone recommend a registered plumber to fit a new Unvented Megaflow including all parts and labour under 1000 including any VAT. As per the attached photos it is housed in the basement. I...

Hi Picasso - do you have any further plumbing diagrams so that I may prepare to purchase an identical Combination Cylinder and connect up a new one ? Also, for all others out there , I have now come to the agreement/conclusion that I need a new cylinder and want to replace 'like for like' &...

....from what I remember of the plumbing (and as per attached photo's), I don't remember seeing an overflow pipe from the header tank part of the cylinder. There is a separate overflow pipe, I remember this input being from a different pipe connection area near the cylinder. Also, I am...

I turned off the main stop cock to empty the top header tank with a small bucket last night then turned it back on - about 1 full turn anti clockwise (to re-open it so not fully open) so, may be, this lowered the pressure and 're fill' rate? I will check again tonight when I get home.

.. also, why would lowering the pressure as I did last night (ie for the lower coil you mention) slow down & possibly stop the overflow above if the upper coil has still 'pinholed' as you say ? Thanks

.. so just to clarify, the problem you suggest still lies with the Cylinder 'pinholing' and hence needs replacing ?

Many thanks for your prompt posts. Just one further addition to my issue, .....before I went to bed last night I reduced the pressure (on the 'Pressure Vessel' - ie the red fat round bulky item - as in the photo) down from about 1.5 Bar pressure to 0.5 Bar pressure) by turning the black...

......offending cylinder. They are in the Album called : 'Water_Cylinder'. Are there any other tests I should do before I replace the cylinder. Also, I have a Potterton boler (small) firing up the heat for this and have been offered a larger Vallient from family (who have replaced for a new...

5 photos of leaking cylinder

I will get some photo's acros to you at around 6pm today (when I get back to the house). Many thanks.

You'll have to educate me on the new terminology though ie 'coil pinholed' & 'Thermal Store'. Could you be saying that water is pinholing out of the internal coil (Heating coil) into the main cylinder lower section and forcing its way out through the bottom 22mm pipe and back into the top...
