Hayward 072184 WASHER SS 7/16"ID X 7/8"OD (SAMPLE W-7)

The Hayward Stainless Steel Washer (W-7) is a critical component in the SP3000 Series Super II Pump, playing a vital role in maintaining the integrity of the pump's internal seals and connections. Its primary function is to provide a secure and stable base for fasteners, preventing them from loosening due to vibration and water pressure. Without this washer, the connections might not seal effectively, leading to potential leaks. Over time, exposure to pool chemicals and constant water flow can cause the stainless steel washer to corrode or degrade, especially if it's not a high-grade stainless steel. This degradation can lead to a compromised seal, allowing water to escape from the pump housing or internal components. If this washer fails and is not replaced, you may notice a decrease in your pool's water pressure, visible water leaks around the pump, or even a complete loss of prime, meaning the pump can no longer effectively circulate water. Addressing a failed washer promptly is essential to prevent further damage to the pump and maintain efficient pool filtration.
