Service Kit includes 3 Orings. SPX1500P is the lid O-Ring for the Hayward Power Flo Pump. It Is designed for the Power Flo 1500, 1510, 1511, 1550, 1575 Series. It also fits the Power Flo LX (1580 series). This O-Ring will not work on the Power Flo Matrix Pump (see SPX5500H).
If a pump is sucking air, spitting air back to the pool thru the inlets, an air leak is causing the problem. This can result in equipment damage, less chemical efficiency,less efficient filtration, and other problems. The first thing to check is the pump's lid O-Ring for small crackage. If the O-Ring is swollen or exhibits cracks, then the O-Ring should be replaced and can be the reason or part of the reason for air leakage.
The gasket is constructed by SSC to the manufacture's specifications.
