Is it ok to cut this 90 degree waste pipe and fit a flexible pan connector?

[tominator]

Hi all,

I'm new here, so please be gentle!

Due to simply being unable to get any response from local trades, I have begun to undertake a downstairs WC renovation.

Despite being modern, all of the pipework in our house is not buried in the walls, so is boxed in. This makes it very difficult to find a modern looking toilet as most are 'back to the wall', but we need a gap to accommodate the boxing. Having found what I thought was one with enough space, its still about 8.5cm out from the wall and I don't want to build the wall out as it will look terrible.

The waste comes up out of the ground, into a 90degree bend, with a very short section of pipe that the pan connector goes into. I can't cut this back far enough to lose the 8.5cm as the pan connector will then be directly into the bend. The section of pipe coming out of the ground has the sink waste coming out of it too, and its all solvent welded together so I can't change anything.

So my question is, can I get away with cutting the bend off at the green line in my photo below, and inserting a flexible pan connector into it? The fins on the flex are 6.5cm, and the distance from the green line to the sink waste is also 6.5cm, so the fins should not impede the flow of water. The concern of course is that if I get this wrong, the pipe goes into the ground, so I need to get it right.

Many thanks in advance for your help!

Tom.

Yes just cut as high as you can.
I would bin the flexi and use a proper bend pan connecter trimmed to correct length.
If your on ground floor rats just love chewing through flexi pan connectors.

Thank you for getting back to me so quickly! I will certainly see if I can get a proper one that lines up... the last thing I need is a rat infestation!!!

we had rats eat 2 lots of flexible pipes on 2 occasions all now replaced with solid pipework , would not recommend flexi pipe surprised i had not heard of this more often
I just thought originally they had been caught when installing as very small holes at the top - so the leak was minor
THEN on another pipe - huge hole

they came up the pipework from the drains - no sign around the area of droppings or anything

Ouch! I think my issue is going to be getting one that lines up perfectly.

Could I combine this:

To achieve what I need?

Thank you!

Having had a look, the standard 90 degree is 165mm from end of the fins to the centre of the pan hole. However, I need it to be 135mm to meet the back of the pan at the correct height, which would mean pushing the fins beyond where the sink waste joins at the side.

Looks like I might have to take my chances with the rats!

Build a false full height wall or a half height unit with shelves/ cubby holes.

TBH I've always been of the opinion that if any soil/drain pipes are getting eaten by rats, flexi's or otherwise then I'd always recommend that drain guards get fitted. Bugger having one of them pop up when on the dunny. Had a couple of clients mention it happening in the city centre, brrrrr ..... sends chills up my spine, luckily never had the experience.

I've also seen rigid connectors/waste pipes/water pips getting chewed too, the buggers chew on anything and everything, they need apparently as their teeth never stop growing.
