Tyler Zowat lives in Perris, California. He wanted his back yard plumbing repaired because it was always dripping water all over his new patio tiles and his patio entrance. He purchased all his plumbing parts from The Home Depot. 

This post shows seventeen steps on how to move a rusted galvanized twin water bibs away from the front door of his new patio area. 

Step 1: It's best to create a plan alongside a parts list. This makes the job easier to do when parts are picked up at your local warehouse store. This job entailed moving the water pipe from near the entrance and across the to the garden patio area. Above right fig.1 shows the last picture from first post. Additional posts are at the end of this post.
Step 2: Fig.2 shows a metal chisel and metal sledge. The cement edges had to be removed around the metal pipe before a schedule 40 male adapter could be inserted. The previous owner had buried the metal pipes in the cement patio never intending on repairing the water pipes that supplied his backyard.

Step 3: Fig.3 shows that the male adapter was sanded with Emory cloth before gluing to the pipe and the 90° Elbows.

Step 4: Fig.4 shows the male plastic adapter is in the metal pipe near the cement. Attached to the adapter is a 2-inch PVC pipe which also attached to a 90° Elbows.

Step 5: Fig.5 shows a 4-inch PVC pipe that will be sanded on both ends before being glued to the adapter and the fig.6 below shows the 90° corner elbow fitting facing down. Between the patio tile and the main cement patio were several inches apart. The irrigation pipes are adjusted to run from the top of the patio to the bottom and to move the water pipes.

Step 6: Fig.6 below shows a 90° Elbows facing down at the cement in a slight angle. This sets up the next pipe to be leveled with the cement floor.

Step 7: Fig.7 shows the 4-inch pipe with another 90° elbows facing the bottom of the patio level.

Step 8: Fig.8 shows a 4-foot pipe stretched across the gate entrance. Fig.9 shows the other side of the door entrance had to be done also so the pipe would not be in the way when the people crossed over the gate threshold.

Step 9: Fig.10 shows the pipe is being placed into a slip union and near it another 10-foot pipe will be used to be near the garden area. The middle of the picture where the pipe stop by the wall is another drop were two more 90° Elbows and a short pipe was used to lower the pipe to another level of the patio.

Step 10: Fig.11 shows the standing wall pipe has been placed into the new ball valve to turn off the water in case of any repairs to the water bibs system.

Step 11: Fig.12 shows the dry positioning of the ball valve to the Tee fitting adjoining the water pipe. Later Cristy's Red Hot Blue glue was used to fuse the pipes together.

Step 12: Fig.13 shows the pipes are sealed and ready to go.

Step 13: Fig.14 shows the pipe is ready for use.

Step 14: Sometime the cut cannot be completed and fig.15 shows that the PVC pipe was placed in the PVC cutter again. It's worth the trouble to get the job done correctly.
Step 15: Fig.16 shows the end of the garden pipe with a without a pipe cap.
