Comments: I have to say im annoyed by people like you who think a job such as replacing a diaphragm on a CDI combi is easy. Ive had many years experience as a boiler engineer and I still find this to be a difficult job to do due to the many "what ifs". Can I just remind yo that you must be gas safe registered to do such work on a boiler like this ....
Admin reply: Hi Dan,
Thanks for your feedback. It is disappointing to hear that my overview of what's involved caused such annoyance; it certainly wasn't the intention. You are correct in saying that diaphragm replacement isn't an 'easy' task per se, however neither is it beyond the wit of someone with a certain level of mechanical aptitude. (Some would argue that if I can do it then anyone can! ) I think you might be surprised that this level of ability is not all that rare given the number of e-mails I receive from others who have succesfully tackled this job; many (perhaps most?) of which have hitherto not even looked inside a boiler before. What they do all seem to have in common however is a desire for a job well done, a certain level of mechanical aptitude and related transferable skills/experience, and perhaps most importantly an approach with due diligence in taking the matter seriously given the potential consequences of getting it wrong.
With regards to your belief that one must be registered with Gas Safe in order to perform this task I would have to disagree with you there. As I know you will be only too aware, but to aid other reader's understanding, the regulations governing such activities are detailed in The Gas Safety (Installation and Use) Regulations 1998, however the nuances of that document do admittedly add up to something more than a one-liner. However, what it is clear upon is that you must be Gas Safe registered if performing 'gas work' (whatever that is) for 'reward' (i.e. payment for the sake of argument) and that if receiving no such reward one must only be 'competent'. It doesn't define 'competent', and it certainly doesn't define it as being Gas Safe registered. As far as the regulations are concerned it is therefore perfectly acceptable to perform this work, for DIY purposes (no reward), without being Gas Safe registered. I would, however, caution against anyone without training/supervision from performing any work on the gas-handling aspects of the appliance - the diverter valve not being one of them.
To clarify, I clearly state that it is not a guide, but rather an overview of what is involved and, in doing so, my aim was to give others a heads up as to what they'd be up against. It is up to them whether they consider themselves competent to attempt the repair, and indeed I regularly receive e-mails from people saying that they were going to give it a go until they read what's involved and decided against it! However, as mentioned, I get other e-mails (far more in fact) detailing success stories so you really shouldn't underestimate the skills of others. Besides which, we are all still your potential customers - particularly for work involving the actual gas side of the appliance - and so I'm not quite sure what your gripe is? You might not find it easy, but others do (or, to be fair, easy enough). There's nothing wrong with either viewpoint and, more to the point, plenty of room for both.
On a lighter note, one only has to read the e-mail I received, and subsequently published on the boiler page, to gain an appreciation that there are indeed a number of "what ifs" to this task! Cheers, Mathew
Comments: 4'X3' sheets of aluminium stored in the loft for seven years!! We might be related?!?! I found your site after googling to fix my boiler, and the cat feeder has made a long evening at work pass with a smile. I hope my wife never finds out about my visit (and future visits) here, or she'll ban the computers. Fantastic site, and the articles are informative and enjoyable. Well done.
Comments: there is a hyundai god......thanks your manuals have stopped the headaches.

Comments: Very cool project, your cat feeder! I also like what you did for World IPv6 day. I sent the link along to a couple of other IPv6 enthousiasts, but they turned out to be too immature for the power bestowed on them... sorry about that.

Comments: Just changed the diaprhagm on my aging 25CDI. Thanks to your article, it went without a problem! This despite sniggering & sharp intakes of breath from the boiler spares man! Having done this job, I think I will maintain the old boiler myself from now on. Many thanks again!
