With the implementation of water-saving sanitary ware standards, there are now clear guidelines for water-efficient products. From faucets to bathtubs, a wide range of water-saving options have hit the market. But how do you choose the right ones? How can you identify their water-saving performance? Let’s take a closer look with the editor.
**1. Water-Saving Faucet**
**1. Main Application Technology – Air Injection**
Most water-saving faucets are equipped with an aerator, which works similarly to air injection technology. The main difference is that the aerator mixes air with water as it flows out, creating a foaming effect that enhances the cleaning power while reducing water usage. This not only saves water but also provides a more comfortable and efficient experience.
**2. Flow Rate and Water Supply Time**
According to the latest water-saving sanitary ware standards, the flow rate for basin, bidet, washer nozzles, and non-contact nozzles should be between 2.0 to 7.5 liters per minute. For delayed self-closing nozzles, the water supply per use should be ≤1.0L, and the duration should be between 4 to 6 seconds. When purchasing a water-saving faucet, make sure to check its flow rate and water supply time.
**3. Check the Spool and Water Effect**
There is a noticeable difference between water-saving faucets and traditional ones in terms of spool quality and water flow. Most water-saving faucets use ceramic cartridges to improve sealing and durability, allowing for thousands of on/off cycles without dripping. Additionally, they create fine bubbles that make the water feel soft and mist-like, improving comfort and reducing splashing.

**2. Water-Saving Shower**
**1. Main Application Technology – Air Injection**
Today, most water-saving showers use air injection technology. By mixing air (typically at a ratio of 1:3) with water, these showers reduce water usage by up to 30% while maintaining high efficiency. Look for air injection holes on the shower head or handle for better performance.
**2. Water-Saving Performance Grades**
The national standard GB/T 31436-2015 classifies water-saving shower heads into three levels: Level I (best), Level II (moderate), and Level III (basic). When purchasing, check the grade label on the product for transparency.
**3. Feel the Soft and Comfortable Spray**
A key feature of water-saving showers is the soft, pulsating spray caused by air injection. This results in larger, gentler droplets that provide a more pleasant experience compared to regular showers.

**3. Water-Saving Toilet**
**1. Main Application Technology – Pressure-Assisted Flushing**
Water-saving toilets typically use pressure-assisted flushing systems to improve efficiency. These systems increase the force of the flush, reducing water consumption while maintaining strong cleaning performance. Other methods, such as waterless designs or wastewater reuse, are less common due to practical limitations.
**2. Water Consumption Must Be ≤5 Liters**
According to the new standard, water-saving toilets must consume no more than 5 liters per flush. Some models even use as little as 4 liters. This regulation came into effect on December 1, 2015, ensuring that all water-saving toilets meet clear criteria.
**3. Check the Flushing Clarity and Water Exchange Rate**
To ensure a toilet is both efficient and effective, check its flushing power. A simple test involves placing 100 floating resin balls in the bowl. After flushing, the fewer balls left, the better the performance (qualified toilets leave no more than 15).

**4. Water-Saving Bathtub**
**1. Main Application Technology – Volume Adjustment**
The design of a bathtub plays a significant role in its water efficiency. Water-saving bathtubs are designed with specific shapes—such as a pyramid-like structure—to optimize volume and reduce water usage. Compared to standard rectangular bathtubs, these models can save up to 20% of water.
**2. Inclined Wall Angles**
The rear wall of a water-saving bathtub is usually inclined at an angle of 110° ± 25° from the horizontal plane, while the front wall is angled at 120° ± 30°. These angles help maximize water retention and minimize waste.
**3. Check the Circulation and Capacity**
Water-saving bathtubs are designed with smaller bases and optimized dimensions (typically 1.2m to 1.7m in length and 0.5m to 0.7m in height). Their compact design makes them easier to stand in, making them ideal for elderly individuals and children.
