I doubt that you will find anything but the conflicting information contained in the instruction manual.
I just tracked down the purported manufacturer of the Via Aqua Seriesof pumps: Commodity Axis. Boy were they hard to find! The web site is VERY shallow and offers very little about the pump itself other than the hard specs, which are available anyhwere the pump is sold.
Here is the company mission statement:
"Commodity Axis, Inc.
-Bringing Products to Life.
Commodity Axis is an importer, exporter and manufacturer of products for the Aquatic industries. Headquartered in the United States, we primarily work with companies within the Pacific Rim-China, Japan, Korea, Taiwan, Singapore, Hong Kong and Thailand.
Another aspect of Commodity Axis' business is the importing of OEM products and manufacturing of private-label products for our targeted industries. We also scout and manufacture products for import, based on the highest quality specifications, while overseeing quality control. Only products meeting our exacting criteria are offered to our clients for import, export or manufacture. There is a modest fee for product searches with additional time being billed as needed. Commission fees are based on a percentage of searched products purchased.
Commodity Axis' service features include:
- Bilingual product research based on client specifications and needs.
