Of all the questions we hear from customers as the top-rated residential service plumber on Chicago’s Northwest Side, “why does my toilet keep running after I flush it?” is probably the most common. Mind you, these questions usually come to us when we’re there assisting on another residential plumbing issue so we’re not being tasked with stopping it – just being asked for information which we freely give. In an effort to help even more people across our service area, we thought we’d share our answers with our website visitors in the hopes that they may help them as well.
