Exclusive to Drain- Net! Canplas are so confident in the integrity and durability of our Grease Interceptor that on return of the Warranty Registration Card printed on the reverse of the Engineering and Installation manual supplied with the interceptor, your standard 12 month warranty will be extended to a full 10 years. In fact the materials used should continue to operate effectively for the life of the plumbing system, so unless you move premises or expand your business to new locations this will probably be the last grease interceptor you will ever need to purchase.
