Name and item number

Evaluation Yes/No

1- Ensure that the pipe connections are suitable so that they are free of leakage 2 - Cleaning the end of plastic pipes from oily materials and dust before applying the adhesive during the bonding process 3. Ensure pressure test two hours after fastening 4. Ensure the diameters of the pipes 5- Ensure that the plastic pipes (PVC) penetrating the external walls are placed within a steel pipe and make sure that these openings are isolated from the inside with two pieces of rubber to prevent water from entering the building 6- Ensure the places of drainage of groundwater away from sweet water 7- Ensure that sweet water pipes are far from electrical installations, gas pipes and saltwater 8. Ensure the tendencies of underground drainage pipes and apply these tendencies accurately 9. Ensure that the ground pipes are well supported at joints, bends and connection points by providing them with supports and supports 10- Drainage pipes are installed in straight lines for the fluidity of water drainage and so that their heads are always directed to the top direction, provided that the pipes are well based on a healthy layer at the bottom of the trenches or concrete mattress and be according to the approved levels 11. Ensure that groundwater is not flooded for the main drilling during rainy seasons
