Mice eating my toilet waste pipe?

[scz4]

Evening,

Noticed this week that water is coming up between my laminate flooring in the bathroom, mostly around the toilet bowl.

Upon closer inspection, looks like my waste pipe has holes in it, not a great situation!! Surprised it doesn't smell worse in there.

So is this mice do you think?

That looks more like a venting pipe than an toilet pipe.

This. That isn’t or rather shouldn’t be a waste pipe. Never seen a waste pipe with ridges ever. If it has been used as a waste pipe then you need to change it

Btw. Looks like plastic degradation to me. Not mice

Definitely the waste pipe (unfortunately).

Black item to the left in the picture is the flush system. Small white pipe is the filler pipe.

Yeah that's mice or rats, it's a common problem with those flexi waste pipes, apparently its because they can see light through them and they try and chew thier way out.
It would be worth replacing it with a solid toilet connector if the space you have allows this.

Hopefully not a rat, can handle mice being in the house.

Will put a trap down tomorrow, although you're suggesting they're in the pipe. It was surrounded in insulation, so wouldn't be any light I don't think.

I think you'll find they're pretty common

Yeah the one on the right is a flexi pan coupled to another flexi. They are smooth bore and twin wall so I'm going to go with eaten through.

I need some new glasses, I read that as mince. Have you been having one too many Keemas?

Not sure about that as the reason - I’ve had the same damage to a plastic container in the garage, and someone posted up a half-eaten windscreen washer filler cap the other day.

Yep, mice. Exactly the same happened behind my lavvy which also had one of those flexys. Unfortunately not possible to line up with a solid pipe so I had to use another flexy which has now worked for ten years.
I know it was mice because one of the little devils got stuck in a hole and I found the corpse.

ETA: they seem to like certain plastics. They destroyed two of my expensive silicone plastic bread-baking "pans", and the plastic back wall of a humane mousetrap. Little gits.

Not sure on the real solution, but perhaps wrap it when fixed in something

Every day is a school day. Never seen them myself - I would have sworn blind that it was a ventilation pipe

[AARONM3]

It will be rodents of some kind - I had the same issue with the same type of pipe. My drain access is just outside the downstairs toilet so after a couple of weeks of replacing the pipe 3 times we had a pest controller fit a metal one-way valve/flap thingy and the problem stopped.

I think it was this one https://www.ratblockers.com/product/2022-new-desig...

I have known of several house fires having started because mice have chewed the insulation away.
So I recommend that you have a thorough look nearby to check if this is just the start of their plans to destroy your entire home.

[scz4]

I've put a few mouse traps down and will see if I catch any tonight.

Although one of the posts above suggested they could be eating it away from the inside.

Would I be best to fully cut open the flexible piping to let anything out? Toilet is out of use anyway so makes no odds really.

SET TRAPS and try to block their access

[scz4]

Yeap. Pipe cut (not a pleasant experience). Two mice traps down with chocolate and one rat trap set in the floor.

Will check in the morning.

We've all seen Tom and Jerry, what you need is a cat, or a few cats... Then when the cats become an issue you needs dogs... Then when the dogs become and issue you need lions.


Or a more solid waste pipe...
