With the stone sub base in place and nicely compacted down we are now ready to start the prep for the concrete. With it being such a big area (11m x 5m) we have split it into two bit size chunks and shuttered these areas so these can be poured first. The concrete is due for delivery on Monday.
In preparation for a new underfloor heating system we have been excavating the floor down to a depth of 450mm and then back filling with sub base (recycled road planeings). The next stage is to lay the 100mm reinforced concrete… more to follow #recycling #reinforcedconcrete #underfloorheating
Derek’s been a busy bee this week looking at flues. At one property, when we went into the loft to inspect the flue, we noticed that the flue hadn’t been screwed together properly and that there wasn’t enough brackets on the flue pipe to hold it in position. The picture on the left shows another section of the same flue which has been fitted correctly. Note the brackets AND screws holding the parts together.
The problems is not that its dangerous NOW, but we have to consider what might happen in the future. If something or someone was to inadvertently interfere with it, the parts could become dislodged and this would allow products of combustion into the house, this in turn may get into the boiler causing it produce carbon monoxide, which of course is deadly. Derek and I determined this to be “At Risk”* and with the owners consent disconnected the gas supply so that it simply couldn’t be used. Documents were completed and issued to the home owner.
By chance, the next day, Derek and I had another call from another customer who had, this time, had his boiler condemned by another Gas Safe engineer and wanted a second opinion as he was facing a bill of several thousands of pounds for a new boiler.
In this case the engineer had determined that the boiler had failed the “spillage test” and the “smoke pellet flue flow test” and had determined that it was “At Risk” and as such issued a Warning Notice and labelled the boiler as “WARNING – DO NOT USE”.
I carried out some tests myself and found them all to be OK, so I rang the gas fitter and asked him what he had found. He said that the CO2% was too low and that I should know that and that is why it’s unsafe. Therefore I rang Baxi to check the figures and was told that there is no published value for the CO2% and so the figure I had found of 6% was fine, not dangerous. I removed the Do Not Use notice and reissued the Home Owner Gas Safety Certificate.
The clients were delighted that they haven’t had to fork out over £2000 for a new boiler and are now confident that their gas appliances are safe.
Bee Safe folks !
* At Risk (AR) means – An “At Risk” installation is where one or more recognised faults are present which could constitute a danger to life or property without further faults developing – further reading available at :- http://bit.ly/beeARAR
A recent study by education charity Edge and the City & Guilds Group found that parents think plumbing apprenticeships make young people more employable than their peers who studied at university, however most of them said that they still wanted their children to get a degree. At the end of the day, what you study is your choice, so it’s pretty important to seek out other routes into employment, and apprenticeships is a pretty good one.
So why not do both? Many companies are now fully aware of the benefits of having graduate engineers who have learnt a “trade”, they understand the business from the ground up and have spent time with semi skilled tradespeople in the shop floor where they will have developed a healthy respect for the value they add to the process. PwC’s retention rate for apprentices is 85.8%, compared with 67.7% for graduates, after qualifying. There is the opportunity for everyone who completes an apprenticeship to remain with PwC and to take advantage of ample career support and job opportunities. pwc.co.uk/higher- apprenticeships
SCIENCE, TECHNOLOGY, ENGINEERING and MATHS – Apprenticeships with degrees exist from these companies and more.
I am delighted to have passed my commercial gas engineer qualifications.This means I can now work on industrial gas equipment such as boilers, air warmers and pipe work, allowing me to service and repair appliances as well as make alterations, purge, test and commission pipelines.
