RODI System Plumbing Example


Installation Example
In this case there are Two RO Membranes running in parallel to produce more water. The DI Housing is located elsewhere in the Van.
Note:
The number one reason why RO membranes fail in the field is the carbon filter dies quickly and is not replaced.
A Regular Carbon Filter replacement and Service interval is important for that.
Which is why our H2Pro and this Build your own System store page offer Carbon Filters with a 1 to 2 year service life.
The small Carbon filter on most system needs to be replaced every 6 to 8 weeks,
The maintenance is not costly as the filters are inexpensive, but very expensive if the maintenance is forgotten, and the Carbon filter is not replaced as once dead it takes a couple of months for the RO to fail and you are now buying a new RO because of that small filter.
