Great prices on your favourite Gardening brands, and free delivery on eligible orders.

Review: Does the job. - Yes the non return valve trap does the job and so far for us this has worked well. We had an infestation of rats with the entry point through the main drains to under our property. We would add that it is a wise idea to regularly check your drains to make sure all is flowing well. But with regard to rats it does the job. Hope this helps.
Review: Flap not very strong! - item doesn't look bad and the idea is ok for blocking rats, but the flap bit not thick enough could be double in thickness, I will come back with an update about the product. Too prices for what you get!

## Features

- STOP RATS FROM DRAINS - One of the primary ingress points for rats into a domestic or commercial property is via the drainage system, either directly from the main sewers or a collapse within the pipe. A drain guard is installed within the inspection chamber to stop rats.
- ONE-WAY FLAP PREVENTION - The Roshield drain guards allows liquids and solid waste to pass down the system whilst preventing access to rats moving upstream. The rats cannot pass or chew through the barrier flap, thus preventing their access to re-infest.
- EASY TO INSTALL PROTECTION - Drain guards require no previous experience with installation and, once installed, needs no long-term maintenance. Drain guards can be installed either at the entrance or exit of the pipe, and the included bolt can be switched to match the flow direction.
- MADE IN THE UK - Are drain guards are manufactured in the UK from 316 stainless steel (marine-grade) and are suitable for the challenging and damp environment found within a drainage system. Our drain guards are used within the professional pest control industry.
- DRAIN GUARD KIT SIZE - This listing is for a 6" / 150mm version. Instructions are included, and we also offer a support video and backup technical help on request. A 4" / 110mm variant is also available.

## Questions & Answers

**Q: Does this fit into a 4" clay pipe as it is slightly smaller than 4" plastic?**
A: Yes,mine is fitted into a clay pipe. You need to squeeze it so that it goes into the pipe - then it expands when you release it to make a tight fit.

**Q: How does this fit in the pipe?**
A: Very simple and effective; the guard is in fact a slightly oversize 4 inch diameter tube with a broad slot down it's length. - To fit it into a 4inch diameter sewage pipe you simply need to squeeze the tube to reduce its diameter, then push it into the drain pipe and, as soon as you release it, it springs back to make a tight fit in the pipe. - Takes a bit of strength to squeeze the tube down to size,but I managed it without too much hassle.
When you do this, it's important to lift the hinged flap up out of the way. Hope this helps.

**Q: Will the guard prevent rubble from the pipes from getting through? I am worried it will get blocked up and cause flooding**
A: It is on a hinge that opens to allow waste to flow out to main drains and stays closed to prevent anything like rats coming up from the main drains.  I would have thought that rubble will block your drains anyway, regardless of whether you have the guard fitted or not.

**Q: I have had rats chew thru flexi pan connectors, which link the WC to waste pipe. Can these be inserted into waste, to stop rats getting at flexi pipe?**
A: Not sure, but we connected it to a defunct pipe which lead into our house and this stopped all infestation... not sure if this answers your question.
