What this video covers
Armand and Liya replace the faulty water tank selector valves on their boat, Cosmo, to resolve persistent air-in-line issues caused by failing seacocks.0:11 The original threaded valves leaked and failed to fully close, preventing the crew from isolating individual tanks.0:44 An initial attempt to use 1/2-inch SharkBite push-to-connect fittings failed because the 15mm tubing was incompatible with the 12mm internal diameter of the SharkBite components, leading to snapped fittings.1:55 The crew successfully installs 15mm Whale push-fit valves, which feature a locking collar that turns green when fully tightened to ensure a secure, leak-free connection.3:00 After installation, the system maintains pressure and allows for reliable switching between the forward, starboard, and aft water tanks.4:53 Replacing incompatible or low-quality plumbing components with manufacturer-matched push-fit valves eliminates air intake and restores proper water management.
