With all the blogs on drains you can tell that it presents more than a few issues and is one of the reasons that jobs need to be re-scheduled…Here again are the basics that have to be followed with any standard drain applaction that is going to be Hot Mopped.
A two-piece bolted clamping ring type drain.
Note: The size and number of bolts is not a factor…remember an adjustable screw in screen top is not part of the clamping ring system
The drain must be lower than your curb height!
Note: This distance needs to be a minimum of 1-1/2″ to 2″ depending on shower pan size.
2″ pipe and drain must be used for a shower
Note: A tub to shower only is one of the most common re-modeling undertakings…tubs are almost always 1-1/2″…and this needs to be bumped up to 2″.
All drains need to set flush and level with your sub-floor!
Note: If the drain can’t be lowered the floor must come up! An over pour of concrete, mortor, or plywood is often used!
