I had put off doing mine, fearing it was a big job to do, and couldnt find the bolt hidden behind some pipework. With a call for help on the site, I got the info I needed.
Turned out to be a very easy job to do. I am sure I am not alone, but when trusted and experienced members like yourself post how tos up, it gives us 'mere mortals' the confidence to do the tasks ourselves
. For this I thank you and all the others who contribute.
