Point-of-Use ecoTAC™ Salt-Free Hard Water Conditioners

Economical, chemical-free solution for protecting water heating appliances and plumbing from scale build up due to hard water

ecoTAC salt-free conditioner

The effectiveness of our popular whole house ecoTAC units in a convenient, cartridge based form, our point-of-use ecoTAC units offer this incredible technology for low-flow applications at an affordable price. Manufactured with quick-connect 3/4" fittings, installation of these treatment systems is as simple as they are efficient.

These smaller hard water conditioners were designed to protect our customers' investment in tankless or more traditional tank type water heaters by being installed on the hot water line right before said water heaters; however, if the flow rate in your home will never exceed 6 GPM (small home or cabin), our largest model could accomodate your whole house needs.

Although maintenance of the tank-based units is already incredibly easy, these point-of-use units take it one step further by providing you with the ecoTAC media in an easy to handle up-flow cartridge shell. These shells feature a built-in sediment filter, and should be replaced every 3 years. With the on/off valves included on the unit, isolation and cartridge replacement could not be simpler.

Operating Conditions / Pre-Treatment Requirements:

The presence of elevated levels of chlorine, iron, manganese, hydrogen sulfide, copper, and certain other contaminants can damage TAC media, reducing its effectiveness and shortening its life. While the media can handle the typical chlorine levels found in municipal water sources, to maximize media life, it is generally recommended that chlorinated city water be pre-filtered through activated carbon to remove free chlorine before the TAC system.

Water exceeding any of the following levels should be pre-treated to reduce contaminant levels below the stated level.

Hardness: if greater than 25 grains per gallon or 425 ppm (mg/l), please call for sizing recommendation

pH Range: 6.5 to 8.5
Max. Water Temperature: 70C (158F)
Min. Water Temperature: must not freeze!
Recommended Pressure: 15 to 80 psi

Chlorine: < 3 ppm
Hydrogen Peroxide: <0.5 ppm
Iron: < 0.3 ppm
Manganese: < 0.05 ppm
Copper: < 1.3 ppm
Hydrogen Sulfide (H2S): must be removed
Polyphosphates and Oils: must be removed


These units come standard with 3/4" John Guest quick-connect fittings for the inlet and outlet. These allow for quick and easy connections to both copper and PEX piping, saving you costs on installation. If the piping in your home is larger or smaller than 3/4", you will require basic couplers to expand or reduce to these connectors. These are readily available at any hardware store.

The ecoTAC conditioner is designed to be installed after any treatment for removal of iron, manganese, hydrogen sulfide, sediment, and chlorine, but before a UV disinfection system and before a chlorinator (if equipped). Polyphosphate feeders should never be placed before a TAC conditioner. TAC treatment should also be done prior to any water heating equipment.

Pre-Treatment Packages

We are pleased to offer several simple, cost effective pre-treatment options for ecoTAC conditioners. Be sure to match the flow rate capacity of the pre-filter system with the flow rate of your ecoTAC unit. Please call us toll free at 1-866-376-2690 for assistance, especially for higher flow rate applications or for pre-treatment concerns not addressed by these systems.
