I’ve seen dozens of threads on here asking about a basic DIY SW setup. It really isn’t too complicated once you get into it. This is my first rendition and it was literally cobbled together 2 hours before I needed to use it on a Dryvit home. I believe total price was just over $400 so its definitely done on the cheap but it works surprisingly well for now.
(1) Marine Deep Cycle Battery
(1) REMCO Fatboy 7.0 GPM/60 PSI Pump
(1) Set of Battery Post Clamps
(2) 1/2" Hose Barbs
(2) Large Battery Boxes
(3) 50’ Sections of 1/2" Water Hose
It’s so simple and ugly but it does a great job!
