RO/DI Question

[Funky_Fish14]

PS. Incase you aren't sure how to find out... check your house water pressure on your water meter (which will be in your basement most likely where the water comes in through the floor(usually) or wall.

You should be able to google the average TDS in your city water (all the water params in fact) but a TDS meter is still a good idea to have especially if you want to monitor your R/O unit's output and condition etc...
