This is a picture of my current setup which is a combination of MDPE,Hoselock and JG Pipes, Merlin RO, double DI and water softener.
I really badly need this system to start manufacturing once pure water is pumped to the van and stop once the Pure water RBC Tank is full.
I also need it to run to the waste water tank/drain after the RO until the TDS drops to around 20 before it is sent to the DI's and pure water RBC (which currently I do manually with the JG valves / I also regen the water softener manually because it has a massive 60psi water pressure and the washing m/c hose blew off the water softener while unattended when on timer regen)
So how do I do it (preferably without metal to avoid freezing)? And what kit would I need?
