Never encountered this before, but hear it's not uncommon. I'm in a flat, there's little room for head, so water pressure relies on a pump, which is now dead. Seeing as I'm looking at £300 to replace it with a decent on, I started wondering about going over to mains pressure, but I'm electric only. I'm a decent plumber, loads of experience with pipework, central heating etc, but I've not done unvented before. Am I right in thinking that it needs certification and can't really be done DIY?
Correct ,G3 qualification required. Why not just replace the pump ,miles cheaper than any conversion .
Out of interest, any idea why the need for certification? Obviously I appreciate that heating water in a sealed system requires caution and care, but it's not THAT dangerous... Is it just another of those schemes like Part P which do nothing useful and just make the authorities money?
Of course I understand that, but there are far more dangerous things which someone could do in their home that are equally, if not more dangerous
Hi If i recall correctly, it’s only a one day course, so may be a good idea, to improve your qualifications for the benefit of your future Plumbing career? Just a thought, Another feather in your quiver, as they say Good luck Peter
If you haven't got a plumbing background you can't do the unvented course Installing unvented requires planning approval
Not sure it require planning approval as such. What is required is that the building control department is informed of it being fitted, this is often done by the cylinder manufacturer as part of their warranty process.
