关于 Derby 的水泵更换
泳池水泵更换与安装
我们在 Derby 的团队服务于北岸以及纳苏和萨福克周边庄园。每次上门均有记录、投保，并由受训专业人员执行。
Derby
Connecticut Gold Coast pools face heavy salt exposure from Long Island Sound and prevailing southerlies. We run monthly corrosion inspections, sacrificial anode replacement, and premium stone-coping sealing to resist scale and pitting.
每次上门以 pH 7.4–7.6、总碱度 80–120 ppm、钙硬度 200–400 ppm 为目标，所有读数均存档。
