A leaking or missing drain plug can quickly turn routine pool maintenance into a bigger problem. The Swimables Hayward-Style Drain Plug Replacement (SW-27-022) is a direct-fit replacement designed to restore a secure seal at the drain port of compatible Hayward-style pool filters.

This drain plug is used to safely drain water from the filter tank during winterization, servicing, or repairs. When the original plug becomes cracked, stripped, or lost, even a small leak can lead to pressure loss, water waste, or equipment damage. Replacing it with the correct plug ensures your filter drains properly when needed—and seals tightly during normal operation.

Manufactured to OEM-equivalent dimensions, the Swimables SW-27-022 installs easily and provides reliable performance without the higher cost of factory-branded parts.

Designed for Hayward-Style Filter Applications

This drain plug is engineered to match the thread size and sealing surface used on many Hayward cartridge and DE filter housings. Proper fit is critical, as incorrect plugs can cross-thread, leak, or fail under pressure.

Using a purpose-built replacement like the SW-27-022 helps protect your filter tank and surrounding equipment.

Durable, Chemical-Resistant Construction

Pool filter drain plugs are exposed to water pressure, temperature changes, and pool chemicals. This replacement plug is made from durable, chemical-resistant material designed to hold up in real-world pool environments.

It provides a snug, dependable seal that helps maintain system pressure and prevents slow leaks that can go unnoticed until damage occurs.

Why Replacing a Worn Drain Plug Matters

A small component plays a big role in system reliability. A worn or damaged drain plug can compromise filter performance and create avoidable maintenance issues.

• Prevents leaks at the filter drain port

• Maintains proper system pressure

• Allows safe draining during service or winterization

• Protects filter housing threads from damage
