Pride Plumbing was called out for two toilet tanks that would run constantly and not fill. We replaced the toilet tanks' water fill valves with new Fluidmaster PRO45B models; their flappers with new Lavelle 54BP black Korky models; and their above-floor braided stainless steel water supply lines with new Mainline MLB19DLMF models. We tested for leaks and proper operation of both toilets with no issues.
