Worn seals can contribute to leakage or binding. Hayward service documentation for SP0410-series valves specifically notes that worn piston O-rings should be replaced with the correct sizes and that incorrect O-rings can cause binding and leakage.\u003c\/p\u003e\u003ch2\u003eCommon Signs to Inspect the Piston O-Rings\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eWater leaks through the valve when it should be sealed\u003c\/li\u003e\n\u003cli\u003eBackwash valve piston movement becomes stiff or inconsistent\u003c\/li\u003e\n\u003cli\u003eExisting piston O-rings are cracked, flattened, swollen, or damaged\u003c\/li\u003e\n\u003cli\u003eValve service identifies worn internal piston seals\u003c\/li\u003e\n\u003cli\u003eYour parts reference calls for the V60-100 \/ SP410-style piston O-ring configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eVal-Pak\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eBackwash Piston O-Ring Set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVal-Pak Part Number\u003c\/th\u003e\n\u003ctd\u003eV60-100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003eV60-100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUPC \/ Barcode\u003c\/th\u003e\n\u003ctd\u003e811636024243\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOriginal Manufacturer Application\u003c\/th\u003e\n\u003ctd\u003eHayward\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eValve Type\u003c\/th\u003e\n\u003ctd\u003ePush-pull \/ slide backwash valve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReference Application\u003c\/th\u003e\n\u003ctd\u003eSP0410 \/ SP410-style piston\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFunction\u003c\/th\u003e\n\u003ctd\u003eSeals the backwash valve piston assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOEM Status\u003c\/th\u003e\n\u003ctd\u003eAftermarket Val-Pak replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eCompatibility \u0026amp; Fitment Notes\u003c\/h2\u003e\u003cp\u003eVal-Pak classifies V60-100 as a Hayward Backwash Piston O-Ring Set.
