I think I’m going to get the stealth150. Good reviews and for hydro
Just remember ro systems rely on pressure and the water coming In at 77 degrees. For every degree below 77 degrees it’ll lose efficiency. So say it can do 12 gallons an hr if the water coming in is say 68 degrees you won’t get anything close to 12 gallons an hr and instead it will create more waste water instead. Now if the water coming in is warmer then 77 degrees it’ll allow more junk to pass the ro membrane making your tds/ppm/ec higher as the membrane swells. They make a blend valve you can tap both your warm and cold lines and blend the water to say 75 degrees and youll get stellar water production with very little waste.

Btw I use these commercially https://reverseosmosis.com/products/tritton-ixc-commercial-reverse-osmosis-system?variant=29813216542764
and this is for home use

That unit is so nice. No ones explained to me how the temps effect the units, thank you for clarifying that!

Double the output of your RO unit while maintaining the same amount of waste water by running two RO membranes in series.
RO ended up causing deficiencies I couldn’t get under control. I ended up switching to Spring water from the local watering hole and been able to keep everything in check better.

Thank you, that's a good thing to know! Maybe I'll add a bunch of PEX before the RO, it should allow the water up warm up to near room temperature.


The article mentions this though, "all water heaters have silt and other sediment in their reservoirs that can damage the membrane and RO unit."
My water is around 1.3 EC and the house I bought had no softener. :wall:
When I tried to flush my water heater the sediment clogged the drain valve!

I knew what to do... Shut off water to the heater and drain it. Remove drain valve and open water supply a bit to flush. Use a coat hanger wire or something through the drain valve bung to loosen up the sediment that's settled on the bottom. I got about a gallon of sediment out of there!
Yes, it messy.
