The raining season is ending soon! Do you have a water ponding backyard or a flooding basement? Please consider to improve drainage system in the yards, cover the sunken patio to basement (see photo). If the basement was equipped with a single-pump sump, please upgrade to a dual-pump system or even a triple-pump system to prevent flooding at power outage.請您考慮改善花園的排水系統，在地庫天井加裝上蓋(見附圖)，若地庫裝有抽水泵的話，請改裝為双重或三重保障的抽水泵，以確保停電時間可以正常抽水。
