Need opinions. RO filter to water heater to shower


Hello all!

This is what I want to do: I want to take a reverse osmosis water filter(one with a 4 gallon tank) and run the water from the 4 gallon tank to a small 2-4 gallon water heater just for quick showers. I would buy one of those .5 gpm shower heads to help restrict flow.

Can anyone help me? I think I will need a small water pump from the RO tank to the water heater to force it out. Would this work?

Things that confuse me are: How will the pump shut off and on? What part do I need to watch pressures? because it's got to be a very small pump I would think.
lastly, when the pump starts to pump from the RO tank will it hurt the RO system?

Thanks for any help!!

Water from an RO unit is quite corrosive and standard water heaters are not designed for this water so even if you solve the pumping issues it is unlikely to work for long.

RO water is definitely not ideal for shower water. Additionally, you will waste a lot of water to get that 2-4 gallon tank filled. And I doubt that this will meet residential code.

That being said, it's possible. You need a vented tank so that the incoming RO water won't pressurize it & it won't contract when discharging.

A small demand pump will control the water on and off as you open the valves on the shower. Just like in an RV. The pump will control its own pressure with a pressure switch.

I'd suggest a point of use demand water heater would be ideal for this.

==================

How about using a fluoride filter cartridge system in-line with the water lines going to the shower or just shower head after the mixing valve? It would require some piping changes, but it sounds like you're willing to do that anyway.

See:

This is only one place where you can get these...there are others. Check for water temperature limits.
