This section outlines what to check before visiting Discount Pool Mart.\u003c\/p\u003e\n\u003ch4 data-end=\"951\" data-start=\"887\"\u003eHow can I confirm the O-136 fits my Pentair Ultra Flo pump?\u003c\/h4\u003e\n\u003cp data-end=\"1182\" data-start=\"952\"\u003eIf your original lid uses Pentair part 39300300, the O-136 is the correct replacement. Many customers bring photos of their pump lid so staff can verify the fit quickly. The O-136 is molded to match the original groove dimensions.\u003c\/p\u003e\n\u003ch4 data-end=\"1248\" data-start=\"1184\"\u003eWill the O-136 work on both older and newer Ultra Flo lids?\u003c\/h4\u003e\n\u003cp data-end=\"1430\" data-start=\"1249\"\u003eYes, Pentair has used consistent sizing for the Ultra Flo lid seal across different production years. As long as the lid accepts the 39300300 O-ring, the O-136 will install cleanly.\u003c\/p\u003e\n\u003ch4 data-end=\"1506\" data-start=\"1432\"\u003eCan this O-ring help fix low suction or difficulty maintaining prime?\u003c\/h4\u003e\n\u003cp data-end=\"1731\" data-start=\"1507\"\u003eYes, worn lid seals commonly cause suction-side air leaks. Replacing the gasket with the O-136 helps eliminate bubbles and improves prime stability. Many walk-in customers replace this O-ring during routine pump maintenance.\u003c\/p\u003e\n\u003ch2 data-end=\"1770\" data-start=\"1733\"\u003eInstallation and Leak Prevention\u003c\/h2\u003e\n\u003cp data-end=\"1884\" data-start=\"1771\"\u003eDiscount Pool Mart customers frequently ask how to seat the O-ring properly and how to ensure airtight operation.\u003c\/p\u003e\n\u003ch4 data-end=\"1938\" data-start=\"1886\"\u003eHow do I install the O-136 on an Ultra Flo lid?\u003c\/h4\u003e\n\u003cp data-end=\"2116\" data-start=\"1939\"\u003eClean the lid channel, lubricate the O-ring lightly with silicone-based lubricant, and press it evenly into the groove. Make sure it sits flat without twists for a uniform seal.\u003c\/p\u003e\n\u003ch4 data-end=\"2182\" data-start=\"2118\"\u003eWhy might my pump still pull in air even with a new O-ring?\u003c\/h4\u003e\n\u003cp data-end=\"2373\" data-start=\"2183\"\u003eCheck the pump lid for cracks, and ensure the lid is tightened evenly. Also inspect the suction plumbing for unrelated leaks. A properly installed O-136 should remove lid-related air issues.\u003c\/p\u003e\n\u003ch4 data-end=\"2430\" data-start=\"2375\"\u003eHow can I tell if the O-ring is sealing correctly?\u003c\/h4\u003e\n\u003cp data-end=\"2585\" data-start=\"2431\"\u003eThe pump should prime quickly and operate quietly without visible air entering the basket. A consistent water level in the pump pot indicates a good seal.\u003c\/p\u003e\n\u003ch2 data-end=\"2626\" data-start=\"2587\"\u003eIn-Store Pickup and Local Guidance\u003c\/h2\u003e\n\u003cp data-end=\"2747\" data-start=\"2627\"\u003eCustomers often visit Discount Pool Mart when dealing with prime-loss issues.
