Pride Plumbing was called out for a water leak behind a shower and an American Standard toilet tank that would run constantly and not fill. For the shower, we found a loose connection on one of its water supply lines which we tightened and stopped the leak. For the toilet, we found that the toilet tank's flapper was deteriorated and not sealing. We replaced the flapper with a new Lavelle 3060BP red Korky universal flapper and tested the toilet for proper operation with no further issues.
