Zodiac – Drain plugs with O-rings, set of 2 – R0446001

This is an official Zodiac replacement part containing two drain plugs, each supplied with its own O-ring seal. Designed specifically for Zodiac FloPro and FloPro VS pool pumps, these drain plugs are used to seal the drain ports located on the pump housing. When correctly installed, they ensure a watertight closure that prevents leaks during normal pump operation and allows for controlled drainage of the pump body during maintenance, winterisation, or servicing procedures.

The drain plugs are a consumable wear item in any pool pump system. Over time, the O-ring seals can become brittle, compressed, or cracked due to UV exposure, chemical contact, and repeated temperature cycling. Replacing them as a preventative measure during seasonal maintenance helps avoid unexpected water loss or pump damage caused by seepage around the drain ports.

Technical details and compatibility

The set contains two drain plugs and two corresponding O-ring seals, providing a complete solution for both drain port positions typically found on Zodiac FloPro series pumps. The plugs are manufactured to OEM specifications, ensuring a precise fit within the threaded drain port openings on the pump volute. The included O-rings are correctly sized to create a reliable compression seal when the plugs are tightened by hand or with a strap wrench. Using original Zodiac replacement parts rather than generic alternatives reduces the risk of cross-threading or inadequate sealing due to dimensional mismatch.

These parts are referenced in the official Zodiac 2018 and 2020 pump spare parts catalogues under part number R0446001 and are compatible with the Zodiac FloPro (e3) and related FloPro VS pump variants. Always check your specific pump model against the official Zodiac parts diagram to confirm fitment before ordering.

Suitability and installation context

This replacement set is suitable for residential pool owners and professional pool technicians working with Zodiac FloPro series circulation pumps. It is particularly relevant during end-of-season winterisation, when drain plugs must be removed to empty the pump volute and prevent frost damage, and then replaced with fresh seals at start-up in spring. It is also appropriate any time a drain plug is found to be leaking, cracked, or missing its O-ring. The installation requires no special tools beyond a suitable wrench for removal of old plugs, and the replacement process is straightforward for both homeowners and technicians.
