Ok I’ve got one of these in the van with new filters about six months ago, recently added a booster pump as tap pressure here is about 20psi now got 60psi. The system is designed to make pure water at 60/40ratio of pure to waste. Now this never happens so am content with 50/50 however the following happens. Pure water is consistent at approximately 1.2 litres per minute, however waste often starts at 1.2 litres per minute but then drops off to a trickle then to zero. This then fowls the ro meaning I have to flush and start the process over again. This goes on a good day for about half an hour and then settles down and all is well, but then sometimes like today two hours later I’m still fiddling and trying to work out what to do. Anyone suffer like this, I can’t leave the system alone ?
