I have done a fair bit of PVC sprinkler pipe repairs at my homes over the years but something strange happened today. I was doing a very simple thing - adding a second sprinkler head in a flower bed.
I purchased a brand new set of Oatley primer and glue, and new PVC pipe. In the final joint the 90 degree elbow came off after glueing like a repelling magnet. So I cleaned up the elbow and pipe with paper towl and sanded both very lightly with 600 grit sand paper. I tried again and the same thing happened. Then I cut off both pieces and glued for the 3rd time holding the joint together for 5 minutes. It was okay afterwards.
I wondered if there was water, but the pipe was absolutely dry.
I wandered if there was a pipe restriction and the elbow was coming off because of air pressure build-up in the pipe. Nope - I blew through the pipe easily.
This was strange. Never had anythings like this ever before. Maybe the new lue formulae is a bit different. Let me know if you know what the issue could be.
