OK I'm not a plumber and in fact I have been known to have nitemares about getting a water leak and flooding damage. We are getting new floor covering in our house and I have to remove the toilet temporarily for the installation. The toilet has a shut/off valve that has not been closed in 35 years and it won't budge and in fact dripped water for a few hours when I tried to turn the handle. Should I: 1) Pay a real Plumber to do the job 2) Shut off the water at the main valve in the basement and remove and reinstall the toilet after the floor covering is finished or 3) Attempt to repair the 35 year old shut/off valve at the toilet ??
