Description
Overview
The HYDRO BAN 4-1/2 in. Mixing Valve Collar is a preformed waterproofing accessory for the valve opening in a compatible shower membrane assembly. Its pliable sheet conforms to the prepared surface and integrates the penetration detail with the surrounding waterproofing.
Features
- Preformed component avoids making the valve collar from loose sheet pieces.
- Compatible with the specified modified or unmodified thin-set installation method.
- Part of the coordinated HYDRO BAN sheet-membrane accessory line.
Specifications
- Collar opening size: 4-1/2 in.
- System: HYDRO BAN Sheet Membrane waterproofing
- Assembly approvals: Use the sheet system’s specified steam-shower/room and IAPMO-approved details
Applications
Use around a correctly sized mixing-valve opening in a compatible shower or steam-shower assembly. The collar seals this local detail; it is not a standalone waterproofing system.
Plan Your Installation
- Verify valve-opening dimensions and clearance before selecting the collar.
- Embed it using the specified mortar and sheet-overlap method, eliminating trapped air and maintaining the required waterproof connection.
- Coordinate it with the surrounding membrane, seams and other penetrations before tile setting.
Common Planning Questions
Does the collar alone waterproof the entire shower?
No. It completes the valve-opening detail within the full membrane assembly.
