## Questions & Answers

**Q: Is this likely to stop rodents from entering if fitted vertically? In my situation there is little chance of back flow which would close the flap.**
A: Hi no it won't work vertically mc alppine make samebut for vertical where the trap will close otheralturnitive is to further along pipe where it is horizontal then install you will need one that fits inside pipe it works well cabinets for bathrooms have this

**Q: Is a similar fitting available for 160mm pipe?    I've got to stop waste coming back up the pipe but its further down the sewer line.**
A: Standard fitting

**Q: Can this be fitted in the manhole in the sewer if it is the same size, or is is only for toilets.**
A: Hi, we have fitted these into the inspection chamber/manhole. They fit inside the feeds into the chamber, and have successfully stopped the smell from a septic tank backing up and stinking out a bathroom. They would also stop rodents getting into the foul system. Hope that helps.

**Q: Can this be used to prevent back draft of wind**
A: From where and in what?

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for rodent problems!
*by M***S on 28 September 2016*

I struggled to source this at both B&Q and Screwfix (genuinely perplexed the staff in Screwfix) before finding it via Amazon and was good value. This worked perfectly for a rodent issue with a downstairs toilet leading directly into a sewer. The barrier valve worked perfectly and fit tightly within the sewer pipe, seems to have eradicated the problem and worked very well.

### ⭐⭐⭐⭐ Four Stars
*by J***I on 30 August 2015*

Seems to work, not RATs have entered my bathroom since fitting.

### ⭐⭐⭐⭐⭐ Stops fumes coming back
*by D***. on 21 July 2025*

Delighted, it did the job, easy to fit ,good price
