Your Husband Botched the Job
A plumber's job is not to come over to your house and embarrass someone who has tried to fix a job himself. Chances are, if you've tried and failed to fix something yourself, the plumber will just come in and quietly take care of the problem. He may chuckle behind your back when you leave the room and regale his plumber buddies with your mistakes over beers at happy hour, but he's really secretly happy you made a real mess of things. He's hoping you can be a constant source of work for him when you continue to screw up your own plumbing jobs.
