One thing that I learned from this forum an a couple years of doing it is to have backups of backups. I’m organizing and trying to be sure that I’m not missing anything. Anytime something fails and I have to buy a part or product to fix it, I buy two or more. Recently I had problems with my burner and it ended up being the high pressure switch. I bought two. I also bought a few other parts that a fellow washer said are prone to fail. Spray bars, sc swivels, reel swivels, spare hose, spare fittings, extra 12v, spare guns, rebuild kits, ppe, unloaders, etc. if it can go wrong, it will. Spend money now and don’t miss out money and look bad when it fails. I’m thinking to buy an extra pump 2021 soon just in case.
What are some things that you recommend keeping on hand? What am I overlooking?
