I am sure that many of you WFP users know how to build your own WFP system but also there are probably many that do not know. I thought then that I would offer my services for free as I am not an engineer, just a good ol window cleaner. If anyone is thinking of switching or wants help building an RO system in a van, trolley, or trailer, then let me know if you need some advise or help building it. As long as you can get to me I will help build it for free as I enjoy doing it and not for any financial reward. I hope I am not breaking any forum rules as I do not want any gain, just want to help. Attached is a photoe of the system that I built in my van - a 2 man system.
