In older Fresno homes, galvanized or early copper lines can develop pinholes that leak slowly inside walls long before a stain appears. The local climate in the central San Joaquin Valley in Fresno can speed up wear on pipes and fittings, so a bill that creeps up through a season is worth checking.
