Thank you. That helps tremendously.I just used the applicators that came with the pvc primer/cement. At first I tried capping the end and applying full vacuum to the pipe still leaked either I didn’t get enough primer and glue in the correct spot into the poorly glued joint or it had too much vacuum not sure then I drill the pvc cap 3/8” hole then tried again and bingo leak fixed. No issues for almost 2 years. The method definitely works you just need patience.
