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 does require some attention to ensure that the hose connections and the cheap nozzle don’t leak everywhere. Like I said, it was made in a pinch and paid for itself on the first job. I will likely invest in the Bandit version 3 for this season and keep this setup on a small cart to haul around to hard to reach places. I believe @squidskc did something similar but I can’t find it now.
Oh, believe me I wanted to. I also wanted to do his flatwork but he said he’ll do those himself. He swore by some rust remover product that he bought at one of the big box stores. I told him good luck with it and thanked him for his business. He was next door to one I was already doing and I had just bought this stuff the day he approached me so I got up early and threw it together, checked for leaks and rolled out. It would not be my first choice though!
