Which RO water filtration system?
 

I am trying to decide between Watts Reverse Osmosis system
versus Watts Zero Waste RO system, sold by Sams Club and Costco
respectively (links below). Which one you recommend? Is it easy
to disconnect them after one year and move to another place?

Thanks for your reply. Another option is to buy water filtered by
machines
available in some major supermarkets, like the type of machine made by
Culligan

How does their water quality compare to the home Watts RO systems?

These are very very similar products and will both work extremely well
with city water supplies. It is a FALSE statement to say that the unit
sold at CostCo has Zero Waste water. It is likely to produce at leasst
one gallon of waste water (brine) for each gallon it produces.

The two units appear to be otherwise identical, EXCEPT the one at CostCo
includes a permeate pump. The silver and black cylinder shown in the
background and its power supply lying in the foreground raise the
pressure on membrane to 70-75PSI. This increases the production rate of
the membrane significantly, so recovery time after draining some water
is much faster.

One thing to keep in mind is that water pressure and water quality are
significant factors affecting the output rate of a RO unit. Water
quality is important, to remove silt, and to remove the chlorine present
in most city supplies. A 75 gallon per day membrane when equipped
with this pump, can deliver up to 50 Gal/Day with good water quality.
The same system minus the pump will produce only about 25 Gal/Day.

Moving one from one place to another will be a problem. You get water
to these units by tapping into the cold water line under the sink.
Removing the unit will require inserting a valve to close off the water
to the unit when you disconnect it. You also have the issue of the
waste water line, which must also have a valve to shut it off when you
remove the unit.

I do not have a Watts RO, but I have been an RO user for 10 years. Don't
want to EVER go back. Will include a whole house RO in my new house
(under $3000)

the machines in supermarkets come with one additional item, a UV
disinfection unit that will kill any bacteria that manages to grow in
the output side of the RO membrane.

The issue with these supermarket vendors is cost. Ok, its WAY cheaper
than bottled water. Most of these on the spot vend machines charge 20
to 25 cents per gallon. The customer is then responsible for cleaning
and disinfecting the container before each use.

If you only use 5 gallons per week, and few households will use less
than that of this wonderful tasting water, coffee, tea, ice, all cooking
water, reconstituted fruit juices..... $1.25 a week, in 52 weeks its
$65, three years its $195, and you should have gotten the unit at
home. No jugs to handle, on the spot delivery and in three years, it
has paid for itself.
