There's so many 'Glen's a the best plumber' topics, but rather than making yet another, I bumped this one from 2010. He still sounds busy like crazy, but he did a great job as usual for me. Not often do trades ask for less than I want to pay.. lol
I had him replace the flappers in 4 of my toilets and one fill valve. We had tried 3-4 'recommended models' at home depot (it was really great of them, first guy says, "buy this one", when we go back another guy says "no, that was the wrong one, use this one", and the third was like "uh, keep trying until you get one that works".
Glen peddles flappers that actually WORK in our crane toilets like its the secret sauce

(And by peddle I mean sells for what he paid for them). If anyone's got running cranes, I suggest you guy the 'Master Plumber Hornet'. Its yellow and not at any of the local places, but you'll probably be able to get them at Noble.. might set you back as much as $3.
Again, you need plumbing, Glen is your man. He's worth waiting around on (although he responded same day to my email and worked around my schedule to see me in a few days).
Go Glen!
