When these O-rings wear, crack, or deform, the valve loses its ability to fully redirect flow — resulting in incomplete backwashing, water bypass, or visible leakage at the valve body. Replacing the full kit restores proper valve operation. Match part number 273109 to the label or documentation for your ABS Backwash Slide Valve before ordering.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePentair Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e273109\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eQuantity Included\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eKit (multiple O-rings)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eWhen servicing the ABS Backwash Slide Valve, replace all O-rings in the kit at the same time — even if only one appears visibly worn. O-rings on the same valve age at the same rate, and replacing them together eliminates the need to re-open the valve for a second repair shortly after. Before seating each O-ring, apply a thin, even coat of \u003ca href=\"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_r172351\" alt=\"Pentair R172351 Lifeguard Silicone Lubricant\"\u003ePentair R172351 Lifeguard® Silicone Lubricant\u003c\/a\u003e to help each O-ring seat evenly, prevent tearing during assembly, and extend service life.
