Boat Toilet Not Working? I Replaced the Jabsco Pump at 82!

I came back to Zephyr IV in Portsmouth Marina to find my Jabsco manual toilet pump had given up completely. No sea drama – just the grim reality of boat ownership staring at me from the heads. So, at 82, I got stuck in. Creaky bones and all. In this video I walk you through the full Jabsco manual toilet pump replacement – why I chose the complete assembly (around £85) rather than just the service kit (around £50), the exact tools you'll need, and every step from closing the sea-cock to the final leak test. ✅ Whether your pump won't draw water, leaks, or the joker valve has finally had enough – this guide will get you sorted. 📌 CHAPTERS 00:00 When the "romance of sailing" meets stark reality 00:16 Diagnosing the fault (pump works but won't draw water) 00:29 Full assembly vs service kit – which to choose? 00:50 Tools and hygiene prep 02:27 Closing the sea-cock (and why you can't see the inlet sea-cock) 02:44 Removing old hoses and the pump 05:32 The Joker Valve – what it does and how to replace it 06:05 Installing the new Jabsco assembly 08:18 Testing for leaks and full function 🔧 PARTS USED • Jabsco Manual Toilet Pump Full Assembly • Replacement Joker Valve (included in full kit) 🛥️ ABOUT THIS CHANNEL I'm 82 years old and sail Zephyr IV – a 35-foot Westerly Ocean Quest based in Portsmouth Harbour – proving that age is no barrier to life on the water. Over 66 years of sailing, plenty of jobs I'd rather not do again, and still going. #BoatToilet #MarineMaintenance #JabscoPump #BoatDIY #SailingLife #BoatMaintenance #WesterlyOceanQuest #SailingZephyrIV
