Yes, it's very expensive but you get what you pay for. A top quality product that does the job. Review: this is seriously well made - I ordered a Nordisk TX11 after receiving a recommendation, its more expensive than other alternative but its a seriously well made, its easy to install and locks securely in the drain. in my situation I needed to install it in a 3m deep sewer pipe, i used 3 extension rods and it was simple. I have absolutely no doubt that this will work perfectly. The service received from Metex Online was also first class - over all I would give this product 10 out of 10 and would give the same rating for service. If you think you have a rat issue this would be my first port of call from now on! ## Features - STOP RATS TRAVELLING THROUGH 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 Rat blocker is installed within the inspection chamber to stop rats movement upstream. By installing a Rat Blocker all upstream branches are protected. - DOUBLE PROTECTION: The Metex Ratwall has two sharp serrated flaps for double protection from rat infestations. This also 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. All models of the Nordisk TX11 Rat Blocker are supplied with reversible flaps so that the same unit can be used in either inlet or outlet pipes. - WRC & VA APPROVED: The only UK rat blocker to achieve Water Research Centre Approval, the benchmark in UK water industry. The Nordisk rat blocker has also passed the stringent VA Approval issued by the Danish certification body, ETA-Denmark, and inspected by the Danish Technological Institute. - PROVEN PROFESSIONAL RAT BLOCKER: Over 250K units installed worldwide, this rat flap is proven in professional pest control use over 10 years and used in 1 in 6 Danish homes. All parts of the rat valve are made of marine grade 316 acid-resistant stainless steel for demanding environments. Unique patented design with expanding sides allows the rat valve to slide into the drain without friction.
