For bore wells without casing pipe and in areas where loose boulders are present in the bore, it is suggested that the size of the bore should be minimum 2” more than the OD of the pipe. This is to prevent the pump from getting stuck up due to loose boulders.
For bore wells with casing pipe, a minimum gap of ½ “between the Internal Diameter (ID) of the casing and OD of the pump are recommended.
