It creates a watertight seal at the drain port, preventing leaks during normal operation. The seal is critical after routine service tasks such as draining, winterization, or internal pump inspection. Even a properly tightened drain plug relies on this O-Ring to maintain pressure integrity. This part restores the original factory sealing surface.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhy This Part Matters\u003c\/strong\u003e\u003cbr\u003e A worn or flattened drain plug O-Ring is one of the most common causes of slow pump leaks. Small leaks at the drain port can lead to equipment pad water damage, corrosion, and motor failure over time. Over-tightening the drain plug to compensate often cracks the pump housing. Using the correct size O-Ring ensures proper compression without stress. Replacing this seal early prevents larger and more expensive repairs.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eKey Features and Specifications\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eWaterway Plastics manufacturer part number 805-0112\u003c\/li\u003e \u003cli\u003eO-Ring size designation #112\u003c\/li\u003e \u003cli\u003eDesigned for pump drain plug sealing\u003c\/li\u003e \u003cli\u003eUsed on select Waterway pool and spa pumps\u003c\/li\u003e \u003cli\u003eCreates a watertight seal at the drain port\u003c\/li\u003e \u003cli\u003eSingle O-Ring component\u003c\/li\u003e \u003cli\u003eRound profile sealing surface\u003c\/li\u003e \u003cli\u003eService replacement part\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eInstallation and Fitment Guidance\u003c\/strong\u003e\u003cbr\u003e Remove the drain plug completely and inspect the sealing groove for debris or damage. Clean the groove thoroughly before installing the new O-Ring. Light lubrication with a silicone-based lubricant is commonly used to prevent pinching during installation. Reinstall the drain plug snugly without overtightening. Confirm by manufacturer part number before ordering.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAbout the Waterway Plastics Brand\u003c\/strong\u003e\u003cbr\u003e Waterway Plastics is a leading manufacturer of pool and spa components used by builders and service professionals worldwide. Their pumps and sealing components are known for consistent sizing and reliable performance. Many original equipment manufacturers specify Waterway parts at the factory level. Replacement components are engineered to match original tolerances. This consistency simplifies service work and reduces installation errors. Waterway remains a trusted industry standard.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCommon Service Context\u003c\/strong\u003e\u003cbr\u003e This O-Ring is typically replaced during pump leak diagnostics or seasonal maintenance. Technicians often identify failure by moisture around the drain plug area. It is commonly swapped whenever a drain plug has been removed multiple times. Keeping spare drain plug O-Rings on hand is standard practice during pump service.\u003c\/p\u003e","brand":"Waterway Plastics","offers":[{"title":"Default Title","offer_id":52008413856018,"sku":"805-0112","price":0.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/2279\/1186\/files\/WWP8050112_0.jpg?v=1770399204","url":"https:\/\/www.aquaterrabackyard.com\/products\/waterway-plastics-805-0112-o-ring-pump-drain-plug-size-112","provider":"Aqua Terra Backyard","version":"1.0","type":"link"}
