About This Product

Designed for fast and efficient installation, the Flash Shower Rough-in Valve provides flexibility for every situation. The Rough-in Valve features a flat back and compact body to ensure a secure and simplified install process that can accommodate smaller spaces. A flush plug is included, which allows both Hot & Cold to be flushed simultaneously for quicker installation and less downtime. Stainless steel fixation ring, with sure-grip flats, keeps flush plug and cartridge in place without screws. Cartridge sold separately.

Highlights

  • Flush Plug: Eliminates the need to remove cartridge during installation and allows installer to flush the lines without cross flow.
  • Stainless Steel Retaining Ring with Flats: Secures flush plug/ cartridge in place and eliminates need for screws. Flats make it simple to loosen ring for quick, easy insertion/removal of flush plug/cartridge.
  • Flat Back: Allows valve to be mounted flush against cross brace for easy and solid installation
  • Cast DZR Brass Valve Body: Resists corrosion due to high chloride and pH levels in water
  • Exclusive Plaster Guard: Plaster guard is designed to protect valve and act as a guide during installation. It can serve as mounting support for thin-wall installations.
  • Wide Rough-in Range: From 1-3/4" to 2-3/4" from finished wall to the back of the valve.

          What if anything do I need to do when double drywalling and tiling the wall this is going into?
          BySep 16, 2024
          1 Answer | 
          Answer This Question

          Hello Josh, Thank you for reaching out to American Standard. The rough valve will come with a plaster guard that you would during the installation. There is a thin wall side of the plaster guard and the other side is for an installation like yours. The guard will stay on until the wall and tile are up and then it is removed, and it will show you where the valve needs to be roughed in at so that you can attach your handle. If you have further questions, please reach out to us using the Contact Us form or Chat option on our website, and an American Standard Consumer Connection Advisor will be happy to assist you.
