Stopped Mr Ratty popping up through the toilet ... yes, really!
I’ll keep this simple: we had an unwelcome visitor finding his way through the drains and emerging via the ground floor toilet. A trail camera confirmed it, which was both useful and something I could probably have lived without seeing.Since installing this drain guard, there have been no repeat performances.It’s sturdy, looks the part, and was easy enough to fit with a few basic tools, and provided you pay some respect to the serated door, very safe. I had to tap mine into place with a hammer to get a secure fit, but nothing complicated. I’ve also set myself a reminder every couple of months to check it over, which just means making sure the flap moves freely and there’s no debris build-up. So far so good, and my goodness, what additional peace of mind!

Good solution to stop rats in drains.
Quick delivery, appears to be very sturdy good quality product. I am confident it will do the job. Good value compared to similar more expensive drain rat guard and in my view a better design.Fitting it, I found it necessary to literally hammer it down into place as the cement surrounding the drain is narrower than 4" drain. Once in the drain the fit was good and will I'm sure stop the rats. As can be seen I fitted on the in the exit drain, meaning I can subsequently easily check that there is no snagging that could cause a blockage and see any evidence (droppings on the side shoulders) of a rat getting though.

Check the direction of flow sticker is correct!
Appears to be a good product so far. I recommend using a rubber mallet or similar to help get the product into the pipe.One thing to note, the product has a sticker to show which way the product should face based on the direction of flow. One of the guards actually had the sticker on the wrong way and nearly caused an extremely unpleasant back up.I definitely should have checked this before installing but blindly trusted what was on the product. As the first guard was fine. WHEN USING CHECK THAT THE METAL FLAP OPENS UP TOWARDS THE DIRECTION OF FLOW. This caused me to triple check the other guard which indeed correctly printed.As the instructions state, worth checking these regularly.

Fits well, easy to install and so far so good controlling ingress.
Ordered 1 then a second few days later to isolate the house drainage system for all ingress areas. Both been installed 1 week now and seems to be a positive solution so far. Narrowed down ingress issues to drains and so far, no further bait takes in the area. fingers crossed this continues!Easy to install, drain reachable at arms length then gentle tap into place with rubber mallet.

Beat the rats!
This rat gate has been a game changer for dealing with a rat issue we were facing. We had been dealing with rat activity under our floors and in the loft. After speaking to a specialist he advised that they were entering through the drains and told us to fit a gate in our drain inspection chamber.The rat gate is a robust, made from stainless steel, and it's clear that the product is built to last. I had seen some plastic alternatives but the risk is the rats will chew through the plastic.Installation was a bit tricky, but manageable. As our drain was relatively shallow, I was able to reach in and fit the guard. It took about 5 minutes, including tightening or loosening the bolt to secure each gate in place. For those with deeper drains, the installation might be more challenging, and a different type of gate may be needed.I initially purchased two of these drain guards several years ago, and recently purchase of a third to cover an additional drain, I checked on the original two. I was pleased to find that there were no signs of rust, wear, or movement—testaments to the product’s durability. There was also no signs of a blockage as the gate allowed liquid and solid waste to pass through while preventing rats from moving upstream.

Problem mit den Ratten was sofort behoben!
Nachdem wir ständig Geräusche von Ratten in unseren Hausrohren hatten, habe ich diese Sperre bestellt. Es war die beste Idee die ich hatte. Meine Nerven können sich wieder beruhigen, das Problem mit den Ratten war sofort behoben.Jetzt können wir wieder schlafen.Der Einbau war für mich als Laien sehr einfach und hat rund 15 Minuten gedauert. Das Material fühlt sich sehr hochwertig an, ich denke das wir jetzt viele Jahre Ruhe haben werden.Allen die mit Ratten ein Problem haben , kann ich diese Rattensperre nur empfehlen.

Total Geil!
Perfekt, wirkt absolut robust, und etwas Gemein, also genau was man sich wünscht.Ich habe die Klappe im Wartungsschacht vorm Haus nachgesetzt um zu verhindern das Nagetiere zu den Fallrohren gelangen.Hat geklappt! Diese klappen habe ich nur gewählt weil sie total wirkungsvoll, fies und gefährlich aussahen...passte zu meiner Stimmungslage, gegenüber den kleinen Tierchen :)
