Question
Under-sink space for a reverse osmosis system
5 months ago
There’s a decent amount of space under the sink. I’ll send measurements soon. How big is the system?

Reverse osmosis can use a fair amount of water to make drinking water. I wondered if you might reclaim it for some non-potable use. Also, did you calculate total water usage with RO? (If you don't boondock, it probably doesn't matter.) I like getting off grid.
Thanks. I haven’t decided how big of a system yet. I’m just trying to save counter space over a countertop reverse RO system.
I went with a Philips under-sink RO. It just fits diagonally and works great. I drain to the underside of the camper instead of filling the gray-water tank; I installed it just beside the hot-water-heater overflow tube.
That’s good to hear that it fits under the sink. Thanks for the link. Are you worried about the drain making it more challenging for your HVAC to keep up or freezing in the winter?
18” high, floor to that shelf the trash bags are sitting on. Also, you do want access to the water heater; mine failed and was replaced.
Any idea what this is? Found on the floor of my Pebble next to the bathroom door. Sort of a flexible, rubbery translucent strip. Like a weather strip or seal, but have no idea where it fell from. Seal at top of bathroom wall? Thanks. Primarily due to no blackout curtain yet above the table, my Pebble has hit 105 degrees here in Florida. Feel like the heat has caused this piece to un-adhese from somewhere.
Figured it out. The item found on the floor of my Pebble is the outer glazing-stop vinyl strip that holds the glass for the bathroom wall in place at the top.
I finally received my blackout curtains today, so hopefully I can drastically reduce heat absorption through the windows, especially over the table, and avoid the overheating while the Pebble is stored that led to the strip being dislodged.
Did you order the blackout curtains when you purchased or after delivery?
It was part of my original Pebble purchase in late December. Glad they finally got the supply resolved. Assume all outstanding orders will now be delivered shortly. Next focus: cameras.
Thanks for the info. Definitely need to upgrade those cameras to surveillance.
Surveillance aside, I’m more focused on cameras online for traffic monitoring while driving. I kind of thought it would be functional by now.
Reverse osmosis purification produces 3–4 gallons of waste for every 1 gallon of purified water. I used such a system on our sailboat to desalinate seawater, with a ratio closer to 7:1. Electrical consumption is also high. Not very practical for dry camping, unless you want to draw and purify water from a stream; see the ITEHIL Portable RO Filtration System.
I’m more worried about being safe than saving water. I’m currently trying out a countertop system that makes about half purified water from the water reservoir.
Of course. I mistakenly assumed you were seeking a full water-system RO unit. The countertop units are interesting; please share your findings.
The one I am testing right now is in the link below. It has a water reservoir of 2.5 liters and a glass carafe of 1.7 liters. All of the waste water is pumped back into the water reservoir when it gets done. They recommend dumping that out, but if you are worried about water waste, I’m sure you could use it for something else. I like the unit, it just feels bulky on the countertop.

I don’t know if Pebble staff has gotten back to you, but here is a photo of the under-sink cabinet area.
The right side panel offers a mounting space of about 18” H × 7” W × 6” D if you remove the little waste container that hangs on the door.
Thanks for the dimensions on the photo. One quick question though: is that 6 inches deep or 16 inches deep? The photo looks deeper than 6 inches.
