Includes a 1/4HP flush pump, 3‑gallon pail with locking lid, (2) 6‑ft PVC hoses, an open‑end wrench, pail opener, and a quick‑start guide—everything you need to set up a closed‑loop flush. 1/4HP HIGH‑FLOW CIRCULATION PUMP (1800 GPH) — Powerful circulation helps move cleaning solution through the heat exchanger efficiently. Submersible pump design makes setup simple for DIY homeowners and pros. (Always unplug the pump when finished.) STANDARD 3/4" GHT HOSES + 6‑FT REACH — Two 6‑ft PVC hoses are designed to connect to common tankless service/isolation valves, creating a simple in‑and‑out loop for flushing and rinsing. Flexible PVC stores easily and is quick to rinse clean after use. MADE FOR TANKLESS HEATERS WITH SERVICE/ISOLATION VALVES — Ideal for routine descaling/maintenance in hard‑water areas. Compatible with most tankless brands that have service ports/valves (including many Rinnai, Navien, Noritz, Rheem, Bosch, Takagi & more). Not intended for systems without isolation valves. DESCALE YOUR WAY (DESCALE SOLUTION NOT INCLUDED) — Use your preferred cleaner—white vinegar or a citric‑acid based descaler (per manufacturer guidance). The reusable kit helps reduce service calls and keeps your heater running efficiently. Descaling agent is sold separately.
