Water Filtration System Update

I had installed a reverse osmosis (RO) system under the sink of Voyager about a year ago.  It is made by Watts and was a really good system making excellent water; however, there were some issues with it.  First, it was difficult to get it to stop leaking in the beginning.  I did manage that.  I also found out that the "T" fitting which is an off-shoot adapter to the main line installed at the shut off valve had to be completely off prior to putting pressure to the RV line.  The sudden surge of pressure popped the push-in plastic lines.  So, to keep this from happening, I found out I needed to open the RO faucet (has it's own), bleed the RV system of air, open the "T" valve slowly, and once the RO faucet is producing water without air, close it.  So, this may sound complicated, but it's not really.  The hard part was the trial-and-error to figure it out.  The second issue was Gina's did NOT like the loss of  under-counter space.  The RO system had a 5-gallon holding tank and it did basically render all space under the sink unusable.  The third issue we had was that it took hours for the system to filter enough water to drink and cook with.  The last issue we had with the system is that for every gallon of pure water made, there were many gallons of waste water depending on how unclean the water was.  When you've got "full hookups" (sewer), that's not an issue as all the waster water filtered by the RO system going into the sewer.  We did have a small issue with wasting so much water, but really not too much.  The real issue for us was the filling up of the Voyager's holding tanks when were not using full hookups.  Regardless, we used the RO most of last year.

This winter cinched the deal for us.  I winterized the RV by blowing out all of the lines with air, but I forgot the filter housings in the RO system were full.  A hard freeze cracked one of the filter bowls rendering it useless.  I let the issue go until now.  We do need filtered water while we travel especially considering all of the places our plans include.  I found single "standard" bowls at Lowes that were reasonable priced and made by Whirlpool.  The quality seemed very good.  The first filter is in Voyager is at the water intake.  I've got a clear bowl with a 5 micron sediment filter.  This will remove most particles, including the very small ones, and protect Voyager's Pex line and water pump.  Under the sink, in the pic below, there are 3 more filters.  The first is a 5 micron carbon block filter designed to remove most other particles, chlorine, other odors, reduce bacteria, and reduce chemicals.  The second filter is a .5 (point-five) micron filter designed to remove everthing else including 99% or better odors, chlorine, bacteria, chemicals, and metals.  The final filter is a finishing filter to improve taste.  Since I had all of these filters with the RO system, my only expense was the bowls and hardware.  Now, we get constant, clean water without waste.  And the best part is Gina gets her space.  If this system doesn't work, I'll let you know and what we decide to do about that.
