step one inspect the signs to determine the position of the server connection two determine the means of access to the drain installation means of access could include the following one a manhole at the sewer connection and man holds its strategic points on the system two a manhole at the sewer connection with bedded inspection eyes at all junctions and changes of direction on the system three a manhole at the sewer connection with rotting eyes brought to the surface of the ground at strategic points on the system and four a rotting eye at the sewer connection with an inspection eye immediately downstream of the rotting eye and rotting eyes at strategic points on the system remove the cover at the connection if sewage can be seen within the manhole or rotting eye this will indicate that the blockage is either in the sewer connection or in the sewer in this case you should tell the property owner to contact the local authority to investigate the problem step 6 if no sewage can be seen within the manhole or rotting eye this will indicate that the blockage is in the drain then proceed as follows manual removal step 7 if it is the case of one is described above remove manhole covers from the manholes until the position of the blockage is located in the case of three as given earlier remove rotting eye covers until the position of the blockage is located in the case of four as described previously remove the inspection eye cover immediately downstream of the rotting eye at the sewer connection and the rotting eye covers until the position of the blockage is located insert a catch stick in the downstream side of the next clear manhole between the blockage and the connection manual securely assemble a corkscrew attachment to three or four clearing rods insert the corkscrew and rods into the upstream side of the drain adding more rods as required until the blockage is reached rotate the rods in a clockwise direction so that the corkscrew enters the blockage material withdraw the rods still turning them in a clockwise direction remove the blockage material from the corkscrew and repeat this procedure until sewage is flowing freely remove the catch stick flush a number of appliances with water to ensure that the drain is functioning correctly in the case of two above blockage removal should be attempted from the connection manhole insert a cat stick in the downstream side of the connection manual and then proceed as just described step nine if the blockage is not removed using the method described in step seven the buried inspection eyes must be excavated exposed and the inspection eyes removed the blockage removal should then be attempted through the inspection eyes using the method described in step 7. you
