US Water Systems Composite Reverse Osmosis Tank | 40 Gallon

Good, not great

Overall, this adds a little water hammer buffer to what we had before this product. Things I don’t like are the lack of an air pressure gauge for the pre-charge. I also wish it was a higher PSI. 20 PSI is too low. I’m running my tank at 43 PSI to not trip the SCALA pump which triggers at 45 PSI. Also, if you increase the precharge air pressure, the volume of water drastically decreases. At 43 PSI, the volume of water is closer to 10 gallons versus 40 gallons.
