Life depends on run hours, water temperature and keeping salt within the manufacturer's range. Low chlorine output at a correct salt reading usually means the plates are worn.\u003c\/p\u003e\u003ch3\u003eWhat salt level does the system need?\u003c\/h3\u003e\u003cp\u003eMost residential systems run between 3,000 and 3,500 ppm. Too little salt reduces output and stresses the cell; too much can trigger a fault and accelerate corrosion of nearby metal.\u003c\/p\u003e\u003ch3\u003eCan I use a salt system with any pool surface?\u003c\/h3\u003e\u003cp\u003eSalt systems work with most surfaces, but soft stone coping, untreated natural stone and some heater components are sensitive to salt. Confirm your heater has a cupro-nickel or compatible heat exchanger.\u003c\/p\u003e\u003ch3\u003eWhy has chlorine output dropped?\u003c\/h3\u003e\u003cp\u003eThe usual causes are a worn cell, scale on the plates, low salt, or cold water. Most systems reduce output below roughly 60F by design. Inspect the plates for white scale before replacing the cell.\u003c\/p\u003e\u003ch3\u003eHow do I confirm this part fits my equipment?\u003c\/h3\u003e\u003cp\u003eCheck the part number stamped on the component you are replacing, or find it on the parts schematic in your owner's manual. If the number differs or is unreadable, send us your equipment model and serial number and we will verify fitment before you order.\u003c\/p\u003e\u003ch3\u003eHow quickly does this ship?\u003c\/h3\u003e\u003cp\u003eIn-stock items ship from our US warehouse on business days. You will receive tracking by email once the order leaves the warehouse.\u003c\/p\u003e\u003ch3\u003eCan I return it if I ordered the wrong part?\u003c\/h3\u003e\u003cp\u003eUnopened, uninstalled items can be returned within 30 days. Equipment that has been installed or plumbed cannot be returned, so confirm fitment before installation.\u003c\/p\u003e\u003ch3\u003eIs this covered by a warranty?\u003c\/h3\u003e\u003cp\u003eManufacturer warranty terms vary by brand and product.
