Please can anyone advise me on a suitable fitting to put in a plasterboard wall so that I can get access to a service valve (ball valve with screwdriver slot head) but close the opening when not in use?
Background detail: the back-to-wall toilet has a service valve fitted, but to get at it would mean unscrewing both the pan and the cistern, unsealing the pan from the flooring and lifting the pan and cistern forwards. I have persuaded the firm who fitted it that this arrangement hardly satisfies the water regulations about having an accessible service valve.
The simplest answer seems to be to to rotate the service valve so that the slot faces backwards, and make a hole in the plasterboard wall behind the toilet. What I need is a fitting that will open to allow a screwdriver (and enough room to see the slot) - say 25mm diameter upwards - but can be closed when not in use.
