FAQ

This plug is designed for 1.5-inch female threaded connections and is commonly used as a filter drain plug or winterizing plug on pool and spa plumbing. Based on the available product information, it is compatible with many Hayward and Pentair applications that use an SP1022C-style 1.5-inch threaded plug.
The confirmed part number for this plug is SP1022C. That is the main reference number shown for this 1.5-inch threaded pool plug with O-ring.
The SP1022C is typically used for pool winterizing and as a filter drain plug. It can be installed in 1.5-inch female threaded ports on pool equipment, skimmers, return lines, or similar plumbing connections where a watertight threaded seal is needed during seasonal shutdown or maintenance.
You may need this plug if your current drain plug is missing, cracked, leaking, or no longer sealing properly. Common signs include water dripping from a threaded drain port, a flattened or damaged O-ring, or difficulty winterizing the system because the port will not seal securely.
Installation is usually simple and takes only a few minutes. In most cases, no special tools are required—just thread the plug into a clean 1.5-inch female port and tighten it snugly by hand. Avoid overtightening, since the O-ring is what creates the seal and excessive force can damage the threads or O-ring.
Before installation, inspect the female threads for cracks, debris, or old seal material. Make sure the O-ring is seated correctly and the sealing surface is clean. If you are winterizing the pool, also confirm the line or filter housing has been properly drained so water is not trapped in the equipment.
The most common causes are O-ring wear, thread damage, overtightening, aging from sun and chemical exposure, and repeated seasonal removal and reinstallation. In winterizing applications, leaks often come from a hardened or flattened O-ring rather than the plug body itself.
