Sanitary ware is an important part of home improvement, and its quality directly affects the quality of daily life, especially the toilet is a product that needs a good performance every day, and its manufacturing process needs to strictly comply with quality control standards and certification requirements.
It is necessary for importers to establish effective quality control procedures to ensure the timely delivery of finished products that meet all relevant quality and safety standards. For brands or retailers, active quality control is essential to meet these challenges and optimize supply chain performance.
There are different types of toilets on the market. Common toilets on the market are generally divided into one-piece toilet assembly and two-piece toilet assembly. In recent years, some companies have chosen to develop smart toilets through continuous technical research, which have warm water washing, warm air drying, and seat Loop heating, sterilization and other intelligent and humanized functions.
How Does The Toilet Work?
When preparing to use a standard household toilet called a gravity toilet, both the tank and toilet are filled with water. When the joystick is pressed, it will lift up a rubber plug called a baffle, which allows the water in the tank to flow into the bowl. Water enters the bowl through small holes around the top of the inner bowl and siphon holes at the bottom of the bowl. Gravity forces the water in the bowl to flow onto the waste pipe. The water flowing into the bowl also cleans the bowl. The water in the bowl is replenished by the water entering from the water tank through the filling pipe.

During the inspection of toilets, we found some common major and minor defects, including but not limited to broken, crack, deformed, glaze bubble, cover deviation, stains, scratches, missing accessories, sharp corners, incorrect barcodes, poor paint, and poor assembly, etc.
Why is it important to Arrange Toilet Inspection?
- Identify any issues in product size/specification to save cost and time
- Reduce defects/flaws in the product and maintain a good brand image of the product
- Save on possible rework and product recall costs
- Confirm that the products will not be damaged during packaging and loading
How to Inspect the Toilets?
Before conducting inspections, AQI technical engineers need to understand your product characteristics to determine key risks. By combining our Toilet Inspection Checklist with your unique product specifications and quality requirements, each inspection can be customized.
We will identify and classify defects based on your Acceptance Quality Limits (AQL), verify the quality of mass production, perform product function and reliability tests on-site, and assess your compliance with product specifications and sizes.
Assess the quality of your product materials and workmanship, using a number of quality control checks and tests, including:
|Barcode scanning test
|Instruction manual check
|Water Leakage check/Leak tightness check
|Stability/Wobble base check
|Ball emissions testing
|Destructive Test for seat cover
|Water consumption check
|Splash pollution check
|Weight check/Loading test
|Colour comparison check
|Product size measurement
Water leakage check
- Fill the product with water and place 1 hour, the toilet shall not have any leakage.
Ball emissions testing
Place 100 polypropylene balls (each ball 19mm dia. 3g) in the toilet, starts flushing, test 3 times, The emission balls shall not less than 85pcs in 3 testing average.
Splash pollution check
A thickness of 10mm, at least 500mm x 500mm template transparent with three pads, support pad above the toilet seat ring 10mm. Start flush, test 5 times and report how many of water drop which greater than 5mm.
a.1 Sawdust test (or by ink):
20g of fine dry wooden sawdust. Moisten the complete inner surface of the WC pan below the flushing rim and above the surface of the water in the trap. Immediately afterwards, sprinkle that sawdust as completely and evenly as possible over the moistened surface. Flush the WC pan and measure any unwashed area. Repeat this procedure 5 times.
a.2 When tested in accordance with a.the arithmetic average of any unflushed area below the rim and above the surface of the water in the trap shall not be more than 50 cm2 after five flushing operations.
b. Flushing of toilet paper:
12 sheets of toilet paper: individuals sheets shall have a size of approximately 140 mm x 100 mm. Individually loosely crumple 12 sheets of toilet paper and drop them separately one after the other into the WC pan within a time of 14 s to 18 s. Operate the flushing mechanism within 2 s of the last sheet being dropped into the WC pan. Check for and remove any paper not flushed out of the bowl and the trap. Repeat this test 5 times.12 sheets of toilet paper shall be flushed out of the WC pan a minimum of 4 times out of five tests.
Performance and reliability are critical to ensure consumer satisfaction. especially Smart Toilets. However, some reliability tests cannot be performed at the inspection site. It requires a specific environment and test equipment to ensure compliance with applicable safety standards and regulatory requirements. AQI Service Inspectors can randomly take samples in production according to customer requirements and forward them to tested by an accredited laboratory.
Quality Control Standards for Toilets
Since the toilet handles body waste every day, stable performance is essential. Toilet manufacturers usually use the following quality control standards when inspecting their products:
|this standard provides a series of tests pertaining to porcelain plumbing fixtures’ materials, dimensions and functionality.
|the standard establishes physical, performance and testing requirements for macerating toilet systems.
|Environmental Protection Agency (EPA) WaterSense Standard
|the standard is for toilet systems with a manufacturer’s claim of water efficiency.
