Detailed Overview of Various Pool Plugs and Their Functions
Pool plugs are generally small components, ranging from a quarter-inch to an inch in diameter, crafted to fit specific parts of your pool system. Below, we delve into the most common types, their functionalities, and ideal applications.
Winterization Plugs
As the colder months approach, winterization plugs become indispensable for protecting your pool. These durable, tapered rubber plugs feature dual stainless steel washers and a central bolt mechanism. When tightened, they expand to create a secure seal, preventing water from freezing inside pipes and skimmers, which could otherwise lead to cracking or damage.
Popular among pool owners, these expansion plugs are available in numerous sizes to match your pool’s specifications. For example, Poweka offers reliable winterization plugs—typically sold in packs of two for around $10. Remember, selecting the correct size is crucial, as these plugs come in more than ten different dimensions to fit various pool models.

- Price Range: Approximately $10 for a pair
Filter Plugs
Filter plugs play an essential role in your pool’s filtration system by sealing off drain openings during maintenance or cleaning. They are male-threaded components that fit into filter outlets or drain ports, preventing water leakage and allowing for proper drainage or pressure testing.
One widely recommended brand is ATIE, which offers versatile filter plugs compatible with leading brands such as Hayward, Pentair, Jandy, and Waterway. A pair of these plugs can be purchased for less than $7, making them a cost-effective solution for routine maintenance.

- Price: Under $7
Pump Plugs
To facilitate the servicing and cleaning of your pool pump, pump plugs are used to drain and seal the pump housing. These plugs are typically 1/4-inch threaded units, often equipped with O-rings to ensure a watertight seal. When replacing or installing a pump plug, check if your model requires a plug with or without an O-ring, and consider using Teflon tape for an extra secure fit.
The Hayward brand offers a reliable 1/4-inch pump plug compatible with most standard models, featuring an O-ring for a tight seal. For larger applications, the Jandy 1/2-inch plugs also come with O-rings and are made from durable materials suitable for frequent use.

Heater Plugs
Heater plugs are small but vital components used to seal the inlet and outlet ports of your pool heater when it’s not in operation. Typically made of brass or PVC, these plugs are equipped with O-rings for a secure, leak-proof fit. They are generally 1/4-inch in size and are essential during winterization or maintenance to prevent debris or water from entering the heater system.
For compatibility, always consult your heater’s manual or contact your local pool store to ensure you select the correct plug size and material suited for your specific heater model.
Hydrostatic Relief Plugs
Located at the bottom center of your pool’s main drain, hydrostatic relief plugs are critical for preventing structural damage caused by hydrostatic pressure when draining the pool. These plugs release accumulated groundwater pressure, thus safeguarding the pool shell from floating or cracking.
There are two main types: automatic relief valves that activate under pressure, and manual plugs that need to be manually opened or closed. The Hayward SP1056 Hydrostatic Relief Valve is a popular, reliable choice for maintaining safety during pool draining procedures.
Test Plugs
Test plugs are large, straight, non-tapering components fitted with wing nuts, designed primarily for pressure testing plumbing lines during installation or repairs. They are usually constructed of steel, rubber, or plastic, and temporarily seal off lines to allow for pressure assessments or leak detection.
If you need a dependable test plug, the Wimdoyily Steel Mechanical Test Plug offers a versatile option that fits most standard applications, ensuring accurate pressure testing and leak prevention.
One-Way Plugs
Specialized for winterization, one-way plugs are designed to permit air to escape from the pool lines but prevent water from returning. These plugs typically incorporate a cap or valve that allows air to flow out, helping to prevent freezing and expansion damage during cold seasons. Once the air is expelled, the water remains sealed, reducing the risk of cracks or pipe bursting.
A recommended model is the Threaded One-Way Swimming Pool Winterizing Valve, which includes a cap and O-ring for secure sealing. Proper installation of these plugs ensures a safe winterization process and long-term protection for your pool system.
