Hidden Floor Fixing on Tavistock Ion WC Pan - Plumbers says it cannot be used.

[Geoff_]

A plumber has installed a Tavistock Ion open backed closed coupled WC in my bathroom. This is part of a full bathroom refurbishment so the plumber has installed the above floor soil pipe from the soil stack. The plumber has also routed pipes below the suspended weyroc floor. There is no electric underfloor heating.

The plumber has not used the proprietary hidden mechanical floor fixing kit because he claims the WC cannot be installed with the floor fixing included. The pan has been 'fixed' with silicone sealant.

My common sense view is that Tavistock would not offer the floor fixing system if it was impractical to adopt.

Is this a common problem or has the plumber failed to tackle the installation appropriately?

Unless the design of the pan does not allow it it should be straight forward to use the fixing kit.

Unless you have underfloor heating either wet or electric, I'd say the plumber didn't fancy drilling those porcelain tiles
Is the pan loose or solid

There is some movement. To make matters worse the boxing is slightly oversize so the cistern is not snug to the wall. This reduces the overall rigidity.

The plumber said that he could not use the floor fixing blocks because he could not lift the pan over the blocks. This implies to me that he did not want to engage the pan outlet to the soil pipe after the boxing & tiling.

The plumber has offered to remove the Tavistock Ion WC and replace it with a Vitra S20 close-coupled open backed WC. This is a fair offer to resolve the issue but should I be worried about differing whites between the Vitra WC and the Tavistock wash basin? The recommendation from the installer prior to work was not to mix sanitary ware from different manufacturers.

Sounds abit of a bodger to me to even contemplate just siliconing the pan down

Reckon 6 out of 10 are done that way that I see every week and few cause problems as long as the cistern is screwed to the wall. Agree it is the easy way out though.

Did the plumber do the tiling and boxing?

From your posts it sounds as though he didnt. If he didnt then he is getting the brown end of the stick.

The boxing should have been done after the wc was installed. Would have been a doddle to use the floor brackets then.

The plumber did the boxing in preparation for the tiler who works for the same bathroom installer.

Well he deserves the brown end of the stick then. Get them to do the job properly.

The reason it doesnt sit back to the wall is probably because he didnt allow for the thickness of tiles on the boxing.

My guess would be there is no slot at the bottom of the pan to slide the pan back over the brackets so it has to be lifted over the brackets but probably couldn't do that and line it up into the pan con at the same time

Why would Tavistock adopt a fixing system on an open backed close-coupled WC that cannot be used in situations that require an open-backed close-coupled WC?

are the floor tiles porcelain? if so they are very difficult to drill,if the cisterns fixed to the wall,that pan is not going anywhere,dont worry about it

This causes me no end of grief when trying to connect the pan spigot to the macerator rubber connecter and can lead me to fit a short McAlpine.
