Toilets, Urinals & Combination Fixtures Specifications

• Is there an accessible pipe chase?
  • If yes, select a rear mounted fixture which is secured to the wall with anchor bolts through the wall.
  • If no accessible pipe chase is available, a front mounted fixture must be used.
• Determine the style of the waste outlet.
  • If the waste connection is on the wall 10" to 12" above the finished floor, this is a blowout style toilet.
  • If the waste connection is on the wall and 4 _" to 5 _" above the finished floor, it is a siphon jet style. Of course, if the waste connection is on the floor, the fixture is a floor outlet style. Normal rough-in for a floor outlet style stainless steel fixture is 4 _" from the finished wall to the center of the waste pipe in the floor.
• Is the fixture wall hung or does it rest on the floor?
• Is the flush valve connection on the back of the fixture or will it be on the top?

• A back supply fixture uses a concealed flush valve.
• A top supply fixture uses an exposed flush valve.

• Is the toilet seat to be integral with a high polished finish or is it a hinged plastic seat?
• If the waste connection is to be made at the wall, can a plain end connection be made using an adapter coupling or must a gasket flange be provided for a gasketed waste connection?
• If the fixture is rear mounted and is being installed on a poured concrete or masonry wall, is security frame (wall sleeve) desired?
