Frequently asked questions.

What is the difference between PYS, KYS and SDS?

PYS is a stainless steel floor drain with waterproofing for wet areas with a membrane; KYS has a compact body for general areas with a low installation height; SDS is a high-capacity point drain with a sealing collar bonded to the flange and S-siphon odour protection.

Floor drain or linear drain?

A floor drain suits classic installations where the floor slopes from four sides. For large-format tiles and a single fall, a linear drain is the better choice; see the linear drain selection guide.
