It seems like the Xero version made for hard-water and regular use is the same as the older Wash-it Pro. I remember reading a thread that Chris posted which made it sound like the Wash-it is junk, and breaks constantly. Have the issues been addressed with the Xero, or is it identical?
I have no idea, but it seems like a business relationship that didn’t work out, but are the Wash-it/Xero units still running into the same issues? I don’t even know what the issues are, but I’m looking into a WFP system for larger projects such as condos and commercial buildings that are interested in my services.
We have a situation where we’re working off an irrigation control valve which usually gives around 40 psi. Hard water and we need to use the wfp for 3000+ windows for up to 60 ft apartment complex. Would RO/DI work with a pump for this? Would I have to use DI only to get to the taller windows and use RO/DI for lower windows? I suppose I will burn through some DI filters in this scenario.
I don’t think you’re going to have success at 60’ with only 40psi, operating in RO/DI mode. I’d recommend a booster pump for sure.
If you’ve got very hard water, operating in DI only mode will kill your resin pretty hard. If you know your average TDS reading, you can use the chart below to determine how many gallons your DI would produce VS RO/DI mode.
But again, if you’re PSI is that low and you need to reach 60’, a booster pump would be your best bet. We have a great 12v pump and a very powerful 110v pump.
