RO/DI unit upkeep

Thanks for all your help. But I hope you can help me now, I found a small stumbling block...
Most of units I am looking at are 15-18" tall and I only have 11"-12" max height to work in under my sink.
Does anyone know of any units that are about 10-11" tall and can put out 25-55gpd?

I bought the aquaticlife power unit works great...what I like about it everything is enclosed and you change the filters from the top. But it’s around 15” tall however it stands on its own base so you don’t have to mount it.

Most of the units are as tall as you say. The inside filter is a standard 10 in tall.
Just measured my individual filter unit, it is 11.75" tall. If you have 12" in you could still mount the unit. Would have to mount the ro membrane, which is atop of the filter unit, separetly somewhere else, just have to plumb it in with longer hoses. And the bracket that mounts the filters, just have to turn the bracket from this: L to this: 7
A seven does not make an upside down L but you know what I mean

Great ideas from hillegom. Just because the units come assembled on brackets etc, doesn't mean you can't get creative in how you wish to mount the assembly. If you get extra tubing and fittings, you can disassemble the whole works, reassemble without the brackets and stand the filters on the floor. Just need to have something for around the base of each cartridge to keep it from falling over.

The measurement of my BWI SR-1 unit, standard 10" transparent containers, is pretty close to 12" from top to bottom without the bracket though, not much room to manoeuver. You could always build a small wooden rack to mount them at a slight angle sitting on the floor, although not too far from the vertical as I don't know how that would affect performance. The RO housing is mounted horizontally anyway. Might seem like a lot of trouble, but by getting standard size cartridges, it's far easier to source replacement filters. When you buy smaller, custom and less common units, you're at the mercy of the OEM's filter format and they often crank up the price because there's no alternative when it comes to filter replacement.

Found a better solution - use a portable unit. Bulk reef supply has some that just hook up to the faucet and I can disconnect and store it when it is not being used.
Without all this discussion I would have never found a solution - Thank you to all!

That can be done with the purchase of a sink adapter on any unit.....

I bought a full unit from Red Coral and picked up a sink adapter from revy.

I make water once a week by pulling out the ro unit from storage hook it up to the sink and tada 0 tds water.

I don't know the price difference between a portable or non portable but if its significant then get the non portable and just store it until you need it.
