GettingBy... BIG HUG I think you are a bit handicapped with expecting your buddle of joy. You are used to doing it. Think maybe you are as frustrated with you not being able to do it alone as you are with his goofing off.
If money not a problem, you should be able to get him to understand hiring a plumber.
I just wanted to send a HUG as know you are better equiped to find solutions than I am.
Has your day improved any?? How about your gratitude list?? I sometimes forget mine.
