So last night, I came to fit the bog to my daughter's bathroom - you remember, the Barcelona whose bag of bits had been missing, and were replaced by the erk in the shop nicking a set from another box on the shelf.
My son-in-law had done a nice job of fitting the syphon unit, and the inlet float unit, with a wipe of silicon rubber here and there, so we were all ready to go. When I came to secure the pan down to the floor, the screw holes went straight in, parallel to the floor, so there was no way to put screws straight down into the floor. I ended up screwing a block of wood to the floor, and then screwing horizontally into that, which has not given what I would consider to be the 'normal' solid fix. The bottom of the pan is not particularly straight, so there is some movement when it is sat on. Any thoughts on that part ?
Anyway, we then went on to fit the cistern and connect up the water. All of that went without problem, and when the water was turned back on, it all started to fill with no leaks. I gave it a test flush with it about 3/4 full, and that was fine, so I let it fill again, and it filled, and filled and filled .... No sign of it cutting off, even though the float was fully up. So, cut the water again, and removed the valve cover / float arm attachment point. No diaphragm in there ...
Son-in-law then comes back with one in his hand. "Is this it?" he says. The instructions claim that this is a spare, so where was the original? I put it in without looking too closely at the rest of the assembly, and screwed back up. Water back on and filling, I lifted the float. No sign of even the slightest reduction in water. So out it comes again for a closer inspection, and it is at this point that I notice that the float arm, when it comes up, pushes on a solid plastic pin at the back of the valve. This part of the valve fits solidly onto the front of the valve assembly, and is then firmly fixed there by the screw-up collar, so cannot move itself. In every valve of this type that I've seen, that pin which is solidly part of the moulding on this one, is a moving pin, which pushes on the diaphragm to close the water off, when the float rises and the arm pushes on it. Interestingly, the 'spare' diaphragm also had a neat hole in its centre, as though it was meant to loacate over something. It does actually fit exactly over a raised lip around the removable part of the valve with the solid pin.
Trust me, nothing does, or can move on this valve, as a result of the float rising. Am I missing something here ? Apparently, even the replacement bag of bits that my daughter was provided with the first time, was open, so maybe that doesn't bode well for the contents ... She's off back down there after work today to demand an unopened bag from the exact same model bog. I don't fancy the chances of anyone there who crosses her on this one. She is mad enough to start screaming and shouting at the store manager now :-)
