Fisher’s DrainKing waste valves feature a stainless-steel rotary ball valve held in a leakproof socket and sealed by two PTFE seals. The valves also feature a “clear through” opening to eliminate the need to disassemble if snaking is required. Surrounding the stainless-steel ball is a solid-brass body designed to the industry standard “sealing” angle, making it a flush fit for stainless-steel sinks. Featuring an extra-sturdy stainless-steel clamping ring, the unit quickly installs without disassembly. Choose from stainless-steel flat or locking basket strainers. Optional vandal-resistant models are available.  It is backed by a three-year warranty.
