Safety Warnings & Critical Care

Depressurize First: NEVER attempt to unscrew the drain cap while the pump is running or the tank is under pressure. This can cause the cap to shoot off with dangerous force.
No Pipe Dope: Do not use pipe joint compound or "pipe dope" on the threads. These chemicals weaken the plastic. The O-ring provides 100% of the sealing work.
Thread Alignment: Be careful not to cross-thread the cap. Since the tank base is plastic, cross-threading can permanently ruin the expensive tank shell.
💡 Pro-Tips for Seasonal Maintenance
  • Hand-Tight is Right: Hand-tighten only to achieve a seal. If it drips, check the O-ring for debris rather than using a wrench, which can crack the plastic threads.
  • Lube the Seal: Apply a light film of silicone-based lubricant to the O-ring before installation. This prevents the rubber from pinching or jumping out of the groove.
  • The Winter Trick: When winterizing, store the drain cap inside the pump basket or the filter's internal manifold to ensure you don't lose the cap or O-ring.
  • Chemical Resistance: Built to withstand harsh outdoor conditions and standard pool chemicals without becoming brittle or leaking.
Product Note: Includes the Drain Cap and O-Ring only.

User Disclaimer: Verify that your filter drain port is threaded for MPT before purchase. Improper removal of drain components under pressure can result in flooding, equipment damage, or personal injury.
