VANPET RV Winterizing Kit with Bypass Valve

The VANPET Upgrade RV Winterizing Kit installs directly onto your RV water pump, providing a hands‑free method for transferring antifreeze into your plumbing system. By simply connecting the kit, the pump does all the work, eliminating the need for messy manual pouring and reducing cleanup each winter.

Included in the all‑in‑one package are durable brass fittings, a 59‑inch siphon hose, a 1/2″ valve with caps, a double‑female adapter, a brass connector, and PTFE tape. The brass components replace standard plastic parts for superior corrosion resistance, while the extra‑long hose offers flexible placement around the vehicle, allowing you to reach hard‑to‑access water tanks without repositioning the pump. Install once and reuse indefinitely for quick, reliable winterization season after season.
