Nice one :)

Haven't we already established all this, like ages ago now. And the OP knows this.

Because it's what I do for a living! 20+ years, and still at it. Fixing heating systems, I'm not an installer. And we had a contract several years ago with Baxi to do their warranty work which I did for 2 years, daily.

It's the preheat valve, mentioned above.

It does unscrew, and if it's dry, then go for it. It will be fairly tight, you just need to grip it without squeezing it. The force required can distort the round shape of your not careful. Depending on the tool you use. Normally a stubby wrench can do the job. Pliers can crush tho.

Sounds like your talking about the INSTANT version of that boiler, and its the pin in the preheat diverter thats stuck (common fault). You need a sturdy tap spanner (see link below for the one I use) with a wrench on the end to get the back nut undone, but in all honesty if the pin is showing...

All good advice so far, but you are aware that by the looks of your picture you don't actually have a compression reducer insert fitted! You have an 8mm to 15mm soldered reducer. This has been inserted into a standard 15mm olive fitting rad valve. By design an olive fitting slightly crushes...

Resoldering isn't the easiest option, it's much better to cut the pipe lower down and use a straight connector to add a new short length of pipe with a new joint into the valve. You can either duplicate what you have by using a 15 to 8 reducer, or a 15 to 8 reducing olive (easier). In either...

The chrome nut can be tightened up, if that's leaking. But support the valve with some grips or wrench so you don't twist it. The 8mm to 15mm reducer would either need resoldering or repkacing and that needs some plumbing skills/equipment.

A scratch isn't an issue, a graze that has gouged a groove or any sort of channel, i would want to repair. Easy for me to say though :) Depends on your diy skills, but it could just be a simple case of cutting the pipe across the damaged area and going over it with a straight or slip fitting...

If a service is due, then that's a great opportunity to get your guy to measure and record the gas pressures for you. It could be that things have changed and it's now on the lowest allowed limit or just below, which would be ideal to call national grid out. Your boiler should to a certain...

It might be worth getting your gas man out to do a working pressure test at the boiler, and the meter. The thing is, that if there is a pressure loss across the pipework, then that's an installer issue, and if the installer is the same chap you use for servicing, he may not be willing to admit...

That's disappointing to hear it's the manufacturer fobbing you off. I'd phone and complain asking for a different engineer to visit. Or if you have it repaired by another qualified engineer, and it's not power flush related, you should be entitled to a full refund from Glow worm. Regardless of...

No offence but that's only as far as you know, a properly qualified and experienced gas engineer will know what to look for, and what to check, and whether something operates or sounds out of the ordinary. Which an unqualified diyer wouldn't be aware of. I'm not saying your wrong, but also you...

You need someone registered with a gas analyser to test combustion, working pressures and flue integrity, amongst a few other things. Power flushing isn't going to fix an ignition fault.
