FAQ

This drain cap assembly is used on many Hayward Pro-Series and Pro-Series Plus sand filters. Confirmed compatible models include S140T, S144T, S164T, S166T, S180T, S210T, S210SV, S220T, S220T2, S230T, S244SV, S244T, S244T2, S270T, S270T2, S310T2, S311SX, S311SXV, S360SX, and S360T2. It is commonly listed for Hayward sand filters produced after 2005, so matching your exact model number is the safest way to verify fit.
SX180LA is a drain cap assembly that typically includes the drain cap, gasket, and screen. These pieces work together to seal the drain opening while helping keep debris from entering the drain area.
Common symptoms include water leaking from the drain port, a cap that will not tighten securely, a cracked or stripped cap, a flattened or damaged gasket, or a missing/broken screen. If your filter starts dripping specifically from the bottom drain area after reassembly or winterizing, the drain cap assembly is a common item to inspect.
Yes. The main replacement part number for this assembly is SX180LA. Some listings also reference HAY-051-2173 as a catalog or cross-reference number. When matching parts, SX180LA is the key number to verify against your filter model.
Installation is usually simple and takes only a few minutes. In most cases, no special tools are needed. Shut off the pump, relieve filter pressure, remove the old cap assembly, inspect and clean the drain opening and sealing surface, then install the replacement cap/gasket/screen assembly. Do not overtighten, since excessive force can damage the cap or sealing area.
Before installation, make sure the filter is off and fully depressurized. Check the drain port threads and sealing surface for cracks, chips, sand buildup, or cross-threading. Clean away debris so the gasket can seat properly. If a new cap still leaks after proper installation, inspect the filter tank's drain opening for damage rather than assuming the cap is the only problem.
They usually fail from age, overtightening, repeated removal during draining or winterizing, UV exposure, and gasket compression over time. In pool equipment, a small leak often starts when the gasket hardens or the plastic cap develops hairline cracks from stress.
