I have contacted 2 more distributors and none are keen on working make repairs and have it all working in top form ,they quckly want to sell a new self serve equipment telling me that it not worth the labour put in repair it, my PLC on the RO System went out and i replace it with a used one that was programmed by Coleman but unfortunately it still has hickup that there is no output coming on i am thinking maybe the PLC is bad or coleman programmed it wrongly, they want 1200$ for a new one. and being new to the business i dont understand much of it .
