Upgrade or replace your RV’s holding tank system with our comprehensive Universal Holding Tank Installation Fittings Kit. Designed to fit RecPro and a wide range of other RV models, this kit delivers all the essential components for a seamless, tool‑free installation. Each set includes three 1 1/2″ grommets (requiring 2 1/2″ holes) and one 3″ grommet (requiring 4″ holes), ensuring compatibility with most standard RV plumbing configurations. The ABS barbed couplers—three 1 1/2″ and one 3″—provide a secure, leak‑free connection to your tank’s waste line.
What sets this kit apart is the inclusion of six high‑quality black tank waste water sensors. These sensors monitor waste levels, giving you real‑time feedback and preventing overflow.
