I have been reworking my sprinkler system and that has involved cutting into the existing CL 200 PVC pipe to add or change fittings. Two things have come up:
1. One of my re-routings requires that a pipe runs across another pipe at a 90 degree angle. The two pipes are touching each other. Will this cause a problem over time, such as expansion/contraction movements wearing down one or both pipes? If so, is there an approved method of dealing with this?
2. The existing 1" PVC pipe near the valves is very discolored from being buried for eight years. I wanted to add a tee in the pipe. No matter how much I washed, sanded or primer-cleaned the pipe, it still remained quite gray looking. I just couldn't get it to look the original white color. I went ahead and glued the new tee in place. Will I have problems later on from a poor joint? Is there an approved method of cleaning an existing dirty underground pipe prior to solvent welding in a fitting?
I look forward to your advice.
