haha

that will work ha ha

It's a pretty standard design. What makes you think it won't work?

Define 'work' ?.

what about square bogs that seem to be rather common these days ?.

Students used to use clingfilm to achieve a similar effect.

Would cling film keep a reasonable head of water out?

Floodwater is rarely a 'reasonable head of water'.

No point sealing the bog, when sewage-contaminated flood water comes through the air bricks, up through the ground under the building, under the doors, ...

In some circumstances the floodwater comes up through the sewers but is not on the ground. It's quite common.

Bill

Equally, there's no point seeing to all those if you don't also seal the loo.

I doubt that gadget would help much, when the pressure simply needs to blow off the pan connector at the back.

Interesting. I have struggled to get those on in the past, so say it takes 20kg pull to get it off. The cross section is around 100 sq cms. So, it would take a 2m head of water to pull it off. Is my maths right?

Obviously, a straight connector won't come off at all. A 90% degree connector would get support from the waste pipe, which I haven't allowed for.

If connected to the same downpipe would the sewage just find another route like pushing out the bath plug and filling the bath?

water will come up at the lowest point...the bath

It all depends on whether the rim of the bath is higher or lower than the rim of the bog, and how deep the flood-water is outside...

yip

and don't buy anything from this shower of crooks as there is no way to contact them when after a few months what you bought has a fault...they won't even reply under their facebook page.....

There'd need to quite a bit of back pressure to get to an upstairs bathroom. In any case, theer's usualya n airbreak between the bath outlet and the sewer.

Many people have the bath on the first floor, but they have a guest loo downstairs. So, the bath won't be a problem, but the kitchen sink might

- or the washing machine stand pipe. All these can be blocked rather more easily (with a rag in a plastic bag, say) than the toilet.

Of course, yes, if the flood water is at first floor level, you do have a bit of a problem.

Are you in a bungalow?

I saw someone unblock a toilet once using cling film, it was in a hotel.

It seemed to be well and truly backed up. After I called reception, he appeared quite quickly and, out of habit I showed him to the problem. Before I even left the room, he had the seat up and was stretching cling film across the throne.

Intrigued I stayed to watch.

He flushed the toilet, the cling film ballooned up (air only), and he pressed it down with the lid.

The blockage cleared. A couple of flushes and off he went.

It couldn?t have taken 10 minutes, probably nearer 5.

No dirty rods or plungers.

What if the cling film breaks? It's very weak stuff.
