WaterMark Product Search
You can search the WaterMark Product Database to check if a plumbing or drainage product has been certified under the WaterMark Certification Scheme, which ensures the product is fit for purpose and authorised for use in plumbing and drainage systems.
If you’re having trouble finding your product, try the advance search options to search specifically for the Licence/Certificate Number; Model ID; Model Name; Brand Name; Product Type; Specification or Licence Holder.
Licence/Certificate Numbers are a 6 digit number, e.g if you have a 4 digit Licence Number you need to add 00 at the start - 001234.
