Yes it is ground floor. Connected into the existing soil pipe that the upstairs loo uses. How can we resolve?
Or have the flexi replaced with hard pipe if possible. It usually is possible to do so and flexi pan connectors are often used simply as an easy or lazy solution. The sewer would be best baited using rat bait boxes put into below manhole covers.
I'd go for replacing the flexi with hard pipe too, but please don't kill the rats. They've just as much right to life as we have.
I don’t like animals being killed either Joe. I even catch spiders and flies etc and release them to outside. Rats can be a problem though and a serious health risk.
Thanks for your advice guys. I think it's pointless trying to kill the rats as there would only be more. I just need to stop them damaging the plumbing.
Definitely needs a rodent barrier or "rat flap" installing. Even changing to rigid means they can still be there and if you are really unlucky, come through the trap on the WC
I have a similar problem. A brand new flexi was installed about 6 weeks ago in a first floor bathroom. The flexi is stretched at an S shape as shown in the picture to fit into the soil pipe. When the toilet was flushed today it leaked. When I investigated, I found that the flexi has shredded in a few different places. I was wondering if the holes in the flexi have been caused by stretching the flexi to get it to fit the S or is because it has been chewed by rats?
If the plastic splits it's usually a straight line ,not jagged and in multiple places. Rodent damage would be by Suspicion. More likely on ground floor ,rather than first floor ,but still possible.
