Use the following table to calculate the dimension (x) to give a minimum effective head of
80 mm required to produce a satisfactory shower in all conditions.
The example below is based on the
“Pipework Schematic Diagram”
with 15 mm pipework,
A = 1.5 m, B = 0.75 m.
(A) 1.5 + (B) 0.75 = 2.25 x 120
(A) + (B) = x 20
Number of Elbows 1 x 55
Number of Elbows x 15
