Plumber hasn’t bolted WC pan to floor - is this right?

[avocadoze]

We have just had a new bathroom fitter and the plumber hasn’t bolted the WC pan to the floor. There are holes either side of the base of the pan for just that.

It’s possible he’s used sealant, but that’s not a long-term fix, is it? And the holes for the bolts will allow any liquids which run down the outside of the pan to get into the space underneath, won’t they?

I think I need pigletjohn or someone who knows this sort of thing as I feel I’m being fobbed off by “nah, love, we use this stuff to fix it these days”.

You are a cowboy by all means , how you will keep guarantee of ditra matt or any other subfloor if you secure the toilet with screws ??? Think before unnecessary comments you,, professionals ,,!

Waterproofing !!! What utter nonsense
. Bad practice is what it's called Embarrassing

Cowboy!! , if you cant scew a pan down and make sure its water sealed after maybe you need to think about things a little more. As many other plumbers have said in this thread the pan should be screwed down.

Never knew there were so many plumbers on Mumsnet. Don't know why but this thread has tickled me this morning Glad they're coming back OP!

The only way to settle this is plungers at dawn!

Fucking hell no wonder I can't get trades, they are all here!

So Pigletjohn is really a Dread Pirate type eh?
Who knew.

Plumbing standards very clear, must be fixed down. Silicone may well fix the cistern but the pan needs screws or if the old type cement. New pans will nearly always have screw holes or plastic fixing kits which fix inside the pan.

I had no idea installing toilets could be so controversial!

OP, did your installer agree it should've been done or are they coming under duress?

Has anyone summoned tagged @pigletjohn? No plumbing related thread is complete with PJ's definitive ruling!

Oh feck...just checked my loo's are fixed down...not one is

This is a new build bungalow (only been in 5 weeks) with wet UFH & ceramic tiling. No screws or silicon...I can actually move the pan.

All you wonderful plumbers...how should I word this problem to my builder?

Who knew this would be an exciting thread! Can’t wait to get home to check my toilets 😂. I have no idea about plumbing but chuckling at the idea of silicon being a type of cement!!

Unlikely in this case but always be careful of drilling or screwing the floor in case of underfloor heating or other pipes

Fascinating thread.

Environmental department from the local council came out to check one of our rental properties, just a random check, not requested by the tenant.

They gave me a list of jobs they considered urgent and immediate and another "optional list" of works.

There were two things on the urgent and we are coming back in 14 days to check list.

1. Fix WC to floor with screws. (Silicon is not acceptable way to fix)
2. Use fireproof boarding to box in the flue where is entered the ceiling.

Well said I would have fixed to the floor with a decent silicone seals it to floor and you would have to give it a ridiculous push to move it and even then very unlikely if you change toilet in future and have drilled floor you left with unsightly screw holes. If it’s a wooden floor screw it down if it’s tiled a decent silicone fine both cases need sealing round bottom to prevent liquids from going under and smelling

Must be a power coup in Dread Pirate Roberts plumbing HQ.
shocked PJ, shocked are you even a woman?
Has someone crossposted to a plumbing forum?

Be careful with the underfloor heating, if it's not moving then don't worry.

As a rule when you are first fixing plumbing you avoid running pipes under areas like the pan. Its impossible to say whether this is the case in your case and as these pipes are always plastic you'll struggle to detect them as well.

I'd hope that the builder would have used a very clever mastic to fix it down.

I heard of a cleaner about 20 years ago that stood on the pan to clean above it. The pan wasn't secure and and tilted and broke cutting the woman's leg so bad it had to be amputated.

Pan in bathroom, fitted a couple of years ago is not screwed down. When I queried this with the plumber he told me it is fine and screws could perforate the underlying pipes. No obvious movement or problems so far.

@avocadoze what did you do in the end? I have got three new WC's and there is nowhere for it to be screwed to the floor whereas in the older AC's there were screws allowing fixing to the floor. I talked to the builder who said he will use silicone to seal it and there shouldn't be any movement 🤷🏽‍♀️
