I bought my northern Florida house in 2017, and I didn't know it would turn grey and green if I didn't clean it. I just got my dad's old 3100-psi Homelite pressure washer working, and I learned that I can clean the house easily with a mix of pool bleach, water, and detergent. So far, so good. The people who make cheap pressure washers say bleach will kill their pumps. I don't care, obviously. A pressure washer pump is cheap compared to paying someone $300 for a 3-hour job. I could buy an entire machine every time I clean the house and still come out even, so buying a pump doesn't bother me at all. I am using bleach regardless of the risk, and after I use it, I shoot pump protector into the machine for whatever good it will do. I have no idea how long I should expect my pump to last, given that I am using about 2.5% sodium hypochlorite. Can anyone give me a ballpark idea, in hours? I would say I'll be putting maybe 10 hours in every year, cleaning the house and workshop. I'm thinking maybe I should go ahead and buy a new pump, because I don't want to get stuck in a situation where I've applied bleach to the house and then can't rinse because the pump has died suddenly. Also, can a pump screwed up by bleach be fixed with a seal kit or something? Thanks.
