Experimental work

1. Sketch the pipework layout for a typical group of sanitary appliances in a

dwelling, where they are all connected into a stack. Show suitable pipe

sizes, slopes and details of the connections at the stack.

2. A range of WCs is to be connected into a common branch pipe of outside

diameter 125 mm fitted within a false ceiling 300 mm deep. It is intended

that the furthest WC should be 18 m from the stack. The branch has a 90°

bend between the last WC and the stack. Determine whether the proposed

arrangement would be satisfactory. If it is not, calculate the maximum dis-

tance that could be allowed between the furthest WC and the stack.

3. Storage soakaway pits 2 m deep are to be used to dispose of rainwater

from a roof of dimensions 10 m x 8 m. Determine a suitable size and num-

ber of pits.
