Plumbing in Laguna Niguel, CA — What You Should Know
Laguna Niguel's South Orange County hill country — from ocean-view estates in Niguel Summit to tract homes in Kite Hill and Marina Hills — sits on steep slopes with decomposed granite soils that shift when winter rains follow dry summers. Imported MWD water is moderately hard, and 1980s–90s construction left copper lines in slabs now hitting their leak-prone decades.
