changing fill valve on concealed lower toilet pan

Ha now you see the practical disadvantages of these poncy toilets!
The toilet pan will be secured to the floor with two or four screws with caps on so you have to take these out. Then remove the screws holding the cistern to the wall. Then gently ease the entire pan/cistern assembly forward until you gain access to the filling valve.
Obvs by this time you will have isolated the cold feed and emptied the cistern.
You might well find that the stem of the filling valve contains a flow restrictor (like a plastic hedgehog) removing same will improve the flow.

 

Just pray the pan was fitted with a Flexi connector and not hard piped to the Pan whilst the scant framework was open then boarded and tiled afterwards!

 

relax, it will be on a flexi pipe to the cistern and a flexi soil conection, how else could the plumber fit it?,,, unscrew the pan and pull out, expect to lose some water from the base of the toilet, have some towels ready, we plumbers hate these toilets too, the salesmen don't explain to the customer they are not serrviceable freindly,

 

Not always, I've seen loads of toilets that go all the back to the wall piped up in copper, was not a happy bunny when I pulled the toilet out

 

And I've fitted a few where a bracket holds the pan connector and then you just shove the whole thing back and hope for the best.

 

I had a barney with bettabathrooms, they sent out one of the fancy toilets but with a standard toilet seat that fits from underneath,I explained to the customer that if i fitted it it would make hard work to replace it when it broke or worked loose or just wanted a change, the bettabathroom salesprick said " thats the seat for that pan",,end of,,,So I fitted it and made it plain to the customer that I was not coming back to replace it,

 

What about those baths with the taps on the long edge against the wall. I always say when, not if, the taps fail you'll have to remove the bath and bottom row of tiles. Style over form?

 

More common than ya think TomP!
Been working on some new builds where the bathroom fitters have fitted back to the wall Pans against studded 4x2 framework and because the framework has yet to be boarded over and tiled they used solid 4" pipe to connect up as they obviously were able to access their hands through the openings.

It was only when I pointed out that once the boarding and tiling had been completed afterwards then how the **** was any Plumber going to reconnect if they removed the Pan?
