About this cord/connector

The Waterway EX2 Drain Plug (715-4020) is an essential plumbing component designed for Waterway spa pumps and circulation systems. This OEM replacement part features 3/8" male pipe thread (MPT) connections, ensuring a secure, leak-free seal when draining your spa for maintenance or winterization.

Engineered to Waterway's exact specifications, this drain plug delivers reliable performance and precise fitment. At Bubbles Supply, we guarantee an exact fit for your spa system, back every part with our comprehensive 1-year warranty, and ship same-day to get your spa running quickly. The durable construction withstands repeated use and temperature cycling typical in spa environments. Always verify thread size and connection type match your existing drain plug before installation to ensure proper sealing and prevent leaks.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Drain plug missing after previous service

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your existing drain plug is 3/8" MPT thread — measure or check the pump label before ordering
  • Inspect the receiving port threads on your pump or plumbing for damage — a new plug won't seal on stripped threads
  • Verify this is the EX2 series pump or component — Waterway uses different drain plug styles across pump families
  • Check whether your existing plug uses a separate O-ring seal or a tapered thread seal, so you have the right sealing material on hand

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
