I’ll revive this older thread to plug my HbrewO system after all these years.  It consistently puts out 0 TDS and 0 chlorine water from my crappy tap water.  Recently it took a hit when I left it outside full of water in freezing temps, and the flow restrictor cracked.  Water gushed out instead of being forced through the filter cartridges and RO membrane.  I contacted HbrewO and Mike is sending me a new flow restrictor.  Because I needed to make some water, I had also ordered these flow restrictors from Amazon which are rated with the same output rate as the original.  They seem to work perfectly with the minor addition of a new piece of 1/4” OD polyethylene tubing to make the connection.
