Supplying warm water to RO

[Oleg30]

Hi Experts,

I might sound strange but here is a problem I'm thinking to solve.

I have an RO system that I need to supply 25-30 C water. Here in Canada during winter the cold water is very cold. I'm considering adding either a mixing valve or a regular faucet to mix hot and cold before RO.
Mixing valve option is not really good as temperature range is 33-70C and requires a high flow of > 0.5 gpm.

Now plumbing a regular faucet could be a problem due to pressure, but not sure.

Can you please advise.

thanks!
