Instructions for use:
The riser pipe is used as rising mains for use in corrosive water to fit India Mark II extra-deep well hand pumps (UNICEF material codes S0009185, S0009186, and S0009187).
This type of riser pipe should be used when water is too acidic for galvanised mild steel pipes.
Furthermore, stainless steel riser pipes should be used at installation depths exceeding 45 metres.
For shallower installation depths, U-PVC riser pipes are preferred, as they are less costly.

Field offices must specify the borehole minimum diameter at time of ordering in order to enable the supplier to correctly select the appropriate riser pipe centraliser.
