Found it at last Drain cock outside, letting by Not sure if it’s the rubber washer inside that needs replacing but going to have to drain the system to check or replace it Would have never noticed, there was just a damp patch beneath it (it has been raining a lot so just never noticed it) oh...

Now that is an idea with the gauge I have had floor boards up traced pipe work, checked all the drops, tried shutting off all the valves (see if it dropped in the pipe work) I was hoping there might be a pin holein a rad, or the pipe work in the conservatory (I can dig that out easy enough...

Okay, I’ll have a shufty on eBay, just thought I should add I have thermostatic valves all round, except the bathroom towel rail can’t do much until Monday now If possible I’d like anyone’s views on the Fernox, has anyone used it ?

Right going to have to answer this bit by bit The pipe work in the conservatory is John Guest plastic with push fit fittings (the ones that twist and lock) it was wrapped in insulation, I wanted the heat in the rads, not under the floor, but that is completely isolated I have used a hydraulic...

I have also checked the valves, in case they were weeping, wrapped them in a paper towel (seems that will show any water leaking from em) Now common sense tells me, if water is leaking, it should show somewhere

Completely isolated, not connected, open ends at the joints going to them (I used push fit elbows to connect them, removed them put cap ends on the pipe work feeding them from the boiler So yes completely isolated I have read the paper work on ferric, it says it doesn’t clog heat exchangers...

Well I can’t find any water anywhere I’ll be using 500 mil bottle, there is inhibitor in it all ready 2 litre MB40 2 rads in the conservatory completely isolated Maybe it will work, I’ll ask Valiant what they say

Okay, when the heating goes off over night, I’ll isolate the boiler from the rads, pump it up to 2 bar and check in the morning But as this has been going on over 2 weeks it should show somewhere Not showing any water in the pipe work from the safety valve or condense line (bags are empty)...

They isolated the boiler from the radiators, 30 minutes, then open up the valves, it didn’t drop from the boiler, just when they opened the pipe work and radiators So my thinking is it’s on the heating side (that is what they said as well, they checked heat exchanger and pressure vessel) I put...

It does but that was checked by Vailiant, the water must be going somewhere, but I’ll be buggered if I can find it

Valiant isolated the boiler for 30 minutes, dropped .2 bar So I am assuming it’s on the radiator side Checked all the drain valves aren’t letting by I bring it up to 1 bar, the hearing is on for 1 hour in the morning and 4 hours in the evening, by the morning the system says 0 bar no sign of...

Yes, Vailiant did that It’s got to the point I have to top it up every day Nothing from the safety valve or overflow

I have a leak somewhere on my heating It’s a combo system, the system has been in over 20 years with no problems New boiler 4 years ago Something has developed a leak I have two radiators in the conservatory whose pipes are under a screed floor, I have isolated them All the other pipes are...
