Why does your toilet keep running? Usually it's one of three culprits: a worn flapper valve, a faulty fill valve, or the float sitting at the wrong height.

A quick replacement stopped the constant water flow and brought the bills back down to earth. S&J Plumbing offers a 10% pensioner discount on all repairs. Book online for toilet repairs across Logan.
