FAQ
Kitchen Sink & Faucet
How do routine maintenance of the kitchen sink?
1. Cautions in routine maintenance:
(i) Keep articles that are prone to rusting away from prolonged contact with the kitchen sink.
(ii) Clean the kitchen sink after each use and wipe it dry with a cloth.
(iii) Try to keep the kitchen sink surface as dry as possible.
2. Unexpected behaviors in cleaning:
(i) To remove mineral deposits on the bottom of the kitchen sink, use diluted vinegar. Afterward, rinse with water.
(ii) Avoid using steel wire balls or abrasive cleaning materials to clean the kitchen sink.
3. Unexpected behaviors in routine maintenance:
(i) Avoid leaving pickles, other pickled foods, mayonnaise, or mustard in the kitchen sink for extended periods of time.
(ii)Do not leave rubber placemats, wet sponges, or cleaning sheets in the kitchen sink overnight.”
How much space should be allocated for the sink?
Ensure a minimum of 40~50mm of space.
How to remove the rust on the kitchen sink?
For rusted areas, use a damp cleaning cloth or cotton cloth (instead of steel wire balls) with a small amount of cleaning powder (such as toothpaste). Gently rub back and forth and then rinse with water.
How to solve the problem of foam coming out of the overflow port?
As an auxiliary accessory, the overflow pipe is used to drain the remaining liquid into the waste pipe. It is connected to the waste pipe.
After pouring the foaming agent and water into the kitchen sink, the water will be drained through the waste pipe due to its heavy weight. The air pressure generated during this process will be relieved through the overflow pipe. The foam is light and bursts slowly. Consequently, the foam that bursts more slowly will be pushed out of the overflow port by the air pressure.
Currently, JOMOO kitchen sinks and most other kitchen sink brands on the market do not have structures to prevent foam or water backflow. This is not a quality issue. It is recommended to use a small amount of dishwashing liquid when washing dishes.
Why is the kitchen sink scratched?
Each JOMOO kitchen sink is made from one-piece 304 stainless steel, which has a relatively low hardness due to the absence of surface treatment. To maintain its surface, it should not be cleaned with steel wire scrubbers or subjected to collisions with sharp objects. It is recommended to clean the sink using a non-abrasive scouring pad.
You may refer to the care instructions on both the product label and the user manual.
How to protect the kitchen sink that has been installed but not used immediately after installation?
After installation, cover the kitchen sink with its polyethylene (PE) bag (or the hole size reference board) to keep it from corrosion by dust or liquids during decoration.
Why does the faucet in the kitchen swing at the moment of turn-on?
It is normal. The rotatable spout of the faucet in the kitchen has a buckle structure. There’s a gap between it and the mounting hole. When the water pressure is large, water rushes up due to the inertia at the moment of turn-on of the faucet, making the spout move up. The larger the water pressure, the larger the radian of swing will be.
Bathtub
How to maintain a bathtub?
1. In routine cleaning, clean the bathtub with soft cloth (or sponge) and clean water. Then, wipe the stains on its surface gently with soft cloth and toothpaste.
Note: Wiping the scales with steel wire balls or hard brushes may cause scratches.
2. Every three months, clean the backwater strainer to prevent blockage from hair or other debris.”
What materials are used in JOMOO bathtubs?
Most JOMOO bathtubs are made of acrylic, while only a few are made of cast iron.
How to remove scratches in JOMOO bathtubs?
To remove scratches, grind them with 2000-mesh fine abrasive paper and water.
Bathroom Accesorries
How to install the angle valve or the cold tap?
1. Rotate to dismount the plug, turn on the water source, clean the inlet hose, and ensure there is no sand or debris to prevent blockage during use.
2. Wrap PTFE tape clockwise around the G1/2 thread on the water inlet of the angle valve. If the angle valve has a decorative cover, mount it onto the angle cover first. Connect the angle valve to the water inlet connector by rotating them (tighten with a spanner). Install the angle valve according to the signs for cold and warm water.
3. Turn on the water source and then turn off the angle valve. After 5 minutes, check for leaks in the inlet hose and angle valve.
Why does the angle valve leak?
Figure out the leaking position. If it is due to a common fault of the connector, replace the gasket; if it is due to a common fault of the water outlet, have the water outlet wrapped with another turn of PTFE tape.
How to maintain the floor drain?
1. To clean the filter, remove the outer cover and filter layer. Use a toothbrush to remove hair and dirt. If the filter remains dirty, use neutral detergent. After cleaning, reassemble the filter layer and outer cover.
2. Maintain the water seal by providing regular water feed. If the floor drain won’t be used for an extended period, seal its outer cover.
3. To prevent blockages, regularly clean the floor drain and avoid disposing of foreign objects or debris into it.
How to maintain the accessories?
1. Ensure good ventilation by frequently opening the bathroom door and window to promote fresh air circulation and maintain family health.
2. Avoid using corrosive detergents. Instead, wipe accessories with a soft cotton cloth and clean water to maintain their glossy appearance.
3. Clean the interior thoroughly every 3 months. After cleaning, wipe the accessory surfaces to prevent water stains.
How to clean the surfaces of polished or elaborately polished accessories of 304 stainless steel? (Accessories of models ending with "AB-1" are stainless steel ones.)
If there are rust spots on the surface of such an accessory, clean surface of the accessory thoroughly with mildew-proof water wax, rinse it and wipe the water on it with soft cotton cloth to make it glossy.
Bathroom Furniture & Mirror
How to maintain the bathroom cabinet?
1. Every week, clean the bathroom cabinet and the bathroom sink with a soft cloth (or sponge) with household dishwashing liquid, clean the faucet with a wet soft cloth, and clean the makeup mirror with alcohol or glass cleaner.
Note: Wiping with steel wire balls or hard brushes may cause scratches.
2. If the screw on a slide, hinge, or handle is loose, have some 502 glue drip into the original screw hole and lock the screw after the 502 glue has cured.
Can another brand's liquid soap be used after the original liquid soap in the bathroom cabinet has run out?
Please use JOMOO liquid soap refills.
1. The liquid soap dispenser can be affected by the liquid soap used. If the liquid soap of another brand is used, the liquid soap dispenser may fail to work normally due to corrosion of its interior as a result of blockage and leakage.
2. If the liquid soap of another brand has a different concentration from JOMOO liquid soap is used, the liquid soap discharge effect will be affected, and the pump will be overloaded. After long-time service, the air intake of the pump may leak, making the liquid soap dispenser abnormal due to interior corrosion and damage.
What is the material of the main cabinet?
Solid wood, stainless steel, composite boards, and PVC.
What is the material of the makeup mirror?
Aluminized mirror, coppered mirror or copper-free mirror.
Why is the color of the bathroom cabinet different from the color seen in the store?
The color of bathroom cabinets may vary slightly between different production batches.
Why is the liquid soap dispenser not responding?
1. Check if the liquid soap dispenser is a rechargeable model. If so, charge it and try again.
2. If it is rechargeable, ensure the power plug is properly connected.
Why is the liquid soap dispenser of the new product not dispensing liquid soap?
Check whether the liquid soap dispenser is correctly installed. In its first use, try a few more times.
Why do the lights fail to turn on or adjust brightness?
1. Check whether the lights are correctly connected to the power source.
2. Check whether the hand waving is correct.
a. Hand waving: Move a hand leftward or rightward through the sensing range within 10 cm in front of the mirror to enable or disable the LED light. When waving the hand, keep all the fingers together (to avoid light leakage) and wave left and right at a uniform speed while the palm faces the mirror.
b. Sensor lights on both sides: Put a hand in a position less than 10 cm under the sensing point at the bottom of the light (the operation can be done from either side) to turn on or off the light.
3. Brightness adjustment: Put a palm in the sensing distance for some time.

How to maintain ceramic products?
1. We recommend descaling a toilet or squatting pan every two weeks. Here’s the method:
(i) Pour toilet cleaner into the water seal (trap) of the toilet or squatting pan.
(ii) After 15 minutes, clean the toilet or squatting pan using a toilet brush and flush it.
(iii) Use a toilet brush with soft bristles to avoid damaging the glaze (avoid using tools like steel wire balls).
2. When flushing a toilet, avoid pressing both flush buttons simultaneously. If you do, the toilet will execute the ECO flush, resulting in poor flushing performance when dealing with a large amount of feces.
How to remove the scales on the water seal of the toilet?
1. If you’re using a toilet in an area with good water quality, clean it daily. Remove scales using dilute hydrochloric acid or an ordinary supermarket cleaner.
2. In regions with poor water quality (e.g., using seawater for flushing), clean the toilet weekly. Use Kangjie 99 Toilet Cleaner and scouring pads for scale removal.
3. If the toilet has hard water deposits or hasn’t been cleaned in a long time, wipe it with fine abrasive paper (with more than 1,000 meshes) using alcohol.
What's the rough-in of a toilet?
The rough-in of a toilet is the vertical distance between the center point of the waste pipe reserved in the floor and the finished tile surface. Typically, it’s either 305mm or 400mm. Here are the installation ranges:
1. For a 305mm rough-in, the range is 290-390mm.
2. For a 400mm rough-in, the range is greater than 390mm.
Note: If the installation range is less than 290mm, installation will fail.
What are the requirements for the water pressure of a toilet? How to measure the water pressure of a toilet?

What's the waste pipe's expected height above the floor?
Drainage pipe must be higher than ground level and less than 1cm
Is the ceramic product new if it has water stains?
Each toilet or faucet delivered undergoes a 100% water test to verify its functionality and leakproofness. Consequently, it may have water or water stains on it, which is normal.
Why is there stool retention on the flushing surface after the flush following each use?
Some people have viscous stool, so it’s recommended to use the bowl pre-wetting function and adjust your sitting posture before use.
There's a big gap between the tank and the tank lid, and there's only one foot pad on four edges of the tank, which results in a big noise. Why?
1. The tank lids are fired together, but they may experience slight deformation due to varying contraction percentages. This can result in incomplete contact between the lids and the tanks.
2. If the front part of the tank does not remain blank when the tank lid’s rear end aligns with the tank and is centered in the left-right direction, the product will not conform to specifications.
3. During production, the tank lid can remain stable with just one foot pad, which explains why there’s only one foot pad.
How to do routine maintenance of the intelligent toilet?
1. The intelligent toilet is an electric appliance and needs to be installed in a dry, well-ventilated bathroom. Direct flushing or spraying with water tends to result in damage to its electronic parts.
2. It is suggested to replace the filter every 4 to 6 months for effective water purification.
Reason: The intelligent toilet filter can filter out large particles such as sand and worm eggs in tap water. However, its filtering effect will decline after about half a year. It should be replaced at regular intervals for a healthy wash and to prevent product failure.
3. It is suggested to descale the intelligent toilet in the following way twice a month: Pour some toilet cleaner into the water seal of the intelligent toilet and flush with the help of a toilet brush 15 minutes later.
Never put foreign objects into the intelligent toilet, otherwise its water circuit may become blocked.
How to clean the seat?
Directly flushing the seat with water tends to cause wetting of the sensor circuit board, resulting in a short circuit of the electrical appliances, and so on. Please avoid striking or stepping on the seat.

Shower
Why does the faucet or the shower head have water leakage?
Check whether water leakage lasts for a couple of seconds after the faucet or the shower head has been turned off. If it does, it is due to the residual water in the faucet or shower head, which is normal.
What are the installation conditions of the thermostatic shower set?
1. Make sure the inlet hoses are correctly connected: warm water hose on the left side while cold water hose on the right side (viewed when you face the inlet hoses), which is the precondition of correct installation.
2. It is suggested to use an electric tank-contained water heater, a gas water heater or an air power water heater.
3. Temperature requirement for the water heater (water temperature check): If the outlet water temperature of the product is different from the set value, an adjustment must be done. It is necessary to make the inlet water temperature 55℃ to 85℃, and the inlet cold temperature 4℃ to 29℃. It is suggested to make outlet water temperature of the water heater 55℃ to 65℃.
4. The operating water pressure should be 0.1MPa to 0.5MPa (recommended value: 0.2MPa to 0.5MPa), and the pressure difference between cold water and warm water should be 0.2MPa (or 50%) at most. Otherwise, a flow regulator (prepared by the customer) should be installed at the inlet hose with a higher water pressure.
5. Installation spacing: The inlet hose connecting thread is G1/2; the cold water inlet and the warm water inlet should have a spacing of 150±10mm.
Why does the handle turn off automatically?
1. The cartridge pressing cap is loose (this is the main reason for the handle descending in half a year). Lock it again.
2. The handle is too heavy or the cartridge is too light. The corresponding cartridge is a 35mm flat-base cartridge. Please replace the existing cartridge with a heavy cartridge (code: K362710-1). If the problem still exists after the replacement, please apply for identification of refund or exchange.
