Surely if the spark gas gone down the rectification side of the board it will be fooked???

I'm not surprised he's reluctant to call them.... they'd p1ss themselves laughing when they find our what he's done! He's an absolute k n o b.

11/4 solvent weld pipe and 11/4 pushfit pipe are slightly different sizes same with 11/2. measure the internal diameter of what goes through the wall and see if you can match it. other than that you are digging into the wall to get a fitting on to it.

You can ask gassafe to inspect the install if you have concerns. Does look a tad iffy to me.

Last really old vaillant I attended had the filling loop next to a downstairs toilet. Cold water supply to the toilet and a radiator circuit next to each other. Boiler was 20 feet away.

Just one bathroom or two? Possibility of a non return valve stuck open in the other bathroom. Causing cold water to mix with the hot water

Have you got a missing bog freshener?

Yes. I'd lift that to 70 tbh.rads need to get to about 55deg before convection starts occurring. Had a few customers who turned their hre's down to 40 deg on the heating side and it affected their hot water. I don't deal with many exclusives, mainly hre and eco rf. Don't see the point in having...

What is the boiler stat set to for the radiators?

I was under the impression that showers were limited to 12l per min? Might be misinformed? A 16l/min shower is achievable with an unvented cylinder but a combi?...mmmmm. My old 1930's stop tap was recently replaced by United utilities, for a modern plastic one. Before the swap I had 15l/min...

Blocked plate hex. First symptom is shower playing up.

What are the dynamic gas pressures at the meter and at the boiler inlet test point? Before we start sl@gging the boiler off!

Quote But I can see if the C/H header happened to be higher than the cold water tank (which is the case in my parent's loft I think), at 0.5L/hr, it might not be enough even overnight to cause the cold water tank to overflow. However, the C/H header float valve would still have to be operating...

Let's not bother trying to rule that possibility out then. I suggest the OP gets a jcb in and rip all the floors up. Rather than drop a spoonful of dye in......... Pinholed coils are unusual, only ever seen two in the 39 years I've been plumbing. 1st one hot water went manky, 2nd one just last...

But they will be using hot water, therefore keeping the level away from the overflow on the hot water header tank. I'm assuming that the heating header tank could be higher than the dhw header tank. I had exactly same scenario last year, pressurised system with a leak. Spent hours looking all...
