What this video covers

Replacing corroded brass seacocks and skin fittings on a 1992 Bavaria 350 requires removing old, brittle components that have suffered from de-zincification.0:05 To extract the old fittings, an angle grinder with a metal-cutting disc removes the flange from the outside, allowing the assembly to be pulled through the hull.5:29 The installation uses DZR brass ball valves and stainless steel hose tails, sealed with Loctite 572 thread sealant.12:29 To prevent the skin fitting from rotating while tightening the internal nut, an 8mm or 17mm combination spanner can be inserted into the internal lugs to hold the fitting steady.13:57 The project also involves rerouting galley sink drains through a single T-piece to free up a seacock for an auxiliary engine cooling water intake.2:53 Proper installation requires ensuring hoses maintain a high loop above the waterline to prevent siphoning.18:35 Using DZR brass or bronze components prevents the structural failure common in standard brass fittings below the waterline.0:22
