US Water 2.5" x 20" Re-Mineralization Filter
Calcite is naturally occurring calcium carbonate media. Upon contact with acidic waters, calcite slowly dissolves and the calcium carbonate raises the pH, which reduces potential leaching of copper, lead and other metals found in typical plumbing systems. It also raises the TDS (Total Dissolved Solids) level of the water and gives it a refreshing mineral flavor for those people that are used to drinking spring or mineral water.
Depending on the pH, water chemistry and service flow, the Calcite cartridge has to be periodically replenished as the Calcite is depleted. In most cases, it lasts up to 6 months.
- Neutralizes water to a pH of 7 to 8
- Adds healthy minerals to the water.
- Available in 3/8 or 1/4 inch inlet/outlet connections
- Includes mounting bracket, screws, and tubing for easy installation.
- Includes 2.5 x 20 Calcite Cartridge

I’ve purchased the white 20” remineralizer and installed it today. I can not get water to flow through the filter. I can remove the filter element and I can get free flow. I have plumbed it to take the RO water in, or I can valve in full house pressure to do the required rinse and valve on outlet to pass to drain. Even the line pressure input will not flow through the filter. I’ve tried a second filter cartridge and same results. I tried blowing through the filter with lung pressure and I can get air to pass...pretty high pressure and very little flow. What could be the problem?
It appears that there is a problem with the cartridges or housings. The cartridges are not compatible with some housings. It is best to call 1-800-608-8792 and ask for tech support. We may need to us refillable canisters for your particular type of housing.
Where should this be installed? In one comment you say to match the tank pipe diameter, so if on the tank line, the water would pass through the filter in two directions as it fills and empties? Or just on the down stream point with unidirectional flow? I’m also surprised there is no mention of flow rate requirements to achieve a desired amount of TDS?
This should be installed between your RO and faucet.
