when sizing your cable length.
Sizing a Geberit cable drain is simple. Start
with acquiring the Tub Depth (see Figure 1),
whichservesasaroughguideforyournal
selection.Whiletheactualdenitionof“tub
depth”variesbymanufacturerandmodel,
the measurement is used to get a rough idea
ofthecablelengthyouwillneed.Usethe
Standard Rough-In Unit Cable Lengths chart
(below,right)todeterminecablelengthbased
on your tub depth.
To assure your rough calculations are correct
andyourBWOwillfunctionproperly,however,
please follow these steps (refer to Figure 1).
1.DeterminetheOverow Depth(A)which
isthedistancefromtheoverowcenterto
drain mounting surface.
2. Determine the Drain Shoe Length(B)which
is the distance from the drain centerline to
theoverowmountingsurface.
3.Choosematerial and joint connection
type. Because material selection and joint
preparationsselectionarecoveredbylocal
codes, be sure a professional contractor
isinvolved.Geberitoersacomplete
spectrumofBWOmaterialstoassurecode
compliance(seepage25).Thematerials
oeredareTubularPolypropylene,Tubular
Brass,ABSandPVC.
4. To determine the nal sizeofyourBWOfor

Onceyouhavedeterminedthesizeandpart
number,youcanalsogivethisinformationto
yoursalesoutletsotheycanverifyyouhave
the right Geberit model for your needs.
