New Water Pump Didn’t Fit… So I Built a Franken Pump!

I thought this would be a straightforward job… swap out the old freshwater pump and fit a new one. It wasn’t. The new pump looked identical, but the quick-fit connectors were just slightly different — enough that nothing would fit. So instead of a simple replacement, this turned into something else entirely… A proper “Franken pump” build using parts from both the old and new units. Along the way, I also explain: • How a boat’s pressurised water system works • How multi-diaphragm pumps actually move water • Why small differences in fittings can cause big problems If you’re working on your own boat systems, this one might save you a bit of head scratching. 👍 If you found it useful, give it a like — it really helps the channel 🔔 And subscribe if you want to follow along with more real-world boat fixes Support the channel / early ad-free access: 👉 https://www.patreon.com/svimpavidus #boatmaintenance #boatrepair #liveaboard #sailinglife #diyboat Sail Safe Guys, Ant & Cid XX 🇬🇧 ⛵️⛵️⛵️⛵️⛵️⛵️⛵️⛵️ =================================================== 👋 We’re Ant & Cid aboard SV Impavidus – two adventurers sailing full-time since 2018.
