Wow! 2000 for a water heater install and that's a good deal? We have gas, the last thing I want is some ignoramus blowing up my home with bad gas work. We put our own replacement in. No big deal. I never realized how lucky I was my dad did all this type of stuff and made me help.
Although I must admit changing out a toilet is intimidating to me. Yes I've helped and yes I'm scared. I am STILL going to change out my own toilets upstairs when we remove the carpet (hopefully next year). I hate carpet.
