SAN-EI has filled in check marks except water saving category.
This is because SAN-EI does not categorize water saving faucets by such water saving parts but by their internal regulation.
According to SAN-EI’s internal regulation, they regard No.1-5, 7-13 as water saving faucets because the faucet is conformity with Japanese Industrial Standard, JIS B 2061 for “Faucet, ball taps, and flush valves”, and also No. 7 has a flow regulating part built in the faucet, while they do not regard No.6 K2530 as a water saving faucet.
However, the most important thing is that JIS does not have the standard for “Water Saving”.
Thus we do not know whether all faucets can be regarded as water saving faucets which follow all clauses TIS regulates.
If you need more specific drawings or data in order to judge what parts has water saving function, I will discuss SAN-EI accordingly.
