How to Locate Leaks in the Kitchen and Bathroom (Kitchen and Bathroom Waterstop)

If water leaks downstairs whenever water is used on the floor, but stops when water is not used, the problem usually lies with the water supply pipes.

Generally, leaks from water pipes are characterized by large, continuous leaks. Pouring water into the floor drain, sink, and toilet will indicate that the drain pipes are not the issue. If the bathroom has not been used for several days but leaks persist and the leak has not lessened, the problem is likely with the water supply pipes.

If the leak is in the drain pipes, you need to locate the exact location of the leak and determine whether partial tile removal is necessary. Complete tile removal is not always necessary.

Extended Information 1: If the leak is in the waterproofing layer of the bathroom, and not in the water supply or drainage pipes:

In such cases, repairs can be made without removing tiles.

The repair method is simple: apply a new type of penetrating waterproofing agent to the bathroom surface to prevent water from seeping into the ground and instead allow it to flow away through the drains.

2: If the problem is with the water supply or drainage pipes... Furthermore, since the water pipes are underground, it's necessary to consider removing the tiles, but a complete bathroom renovation isn't always required.

For example, if the water inlet pipe is leaking, it can be replaced with an exposed pipe, eliminating the need for the leaking pipe.

What is the waterproofing height for a kitchen? (Height of the waterproofing strip in the kitchen and bathroom)

The minimum waterproofing height in the kitchen is 30 cm, with a standard height of 1.3 meters. After the waterproofing is dry, it should be tested for 48 hours with no water seepage to the surrounding area; only then is it considered合格 (qualified/acceptable).

If you're installing waterproofing in the kitchen, the walls also need to be waterproofed.

Because the kitchen is a place that frequently comes into contact with water in daily life, it's crucial to have proper waterproofing in place to prevent larger problems caused by leaks later.

Waterproofing should be done on the entire floor of the kitchen, and the walls should also be waterproofed up to 30 cm. The sink should be about 50 cm higher than the water outlet.

When waterproofing, it's recommended to first apply a layer of waterproof mortar, followed by a layer of waterproof coating, which can better prevent leaks. It's also advisable to reinforce the waterproofing of key areas first, and then proceed with overall waterproofing.

What are the construction and acceptance standards for waterproofing in kitchens and bathrooms? (Specifications for waterstops in kitchens and bathrooms)

The relevant construction and acceptance standards for waterproofing in kitchens and bathrooms are as follows: The "Code for Acceptance of Construction Quality of Building Ground Engineering" and the "Code for Design of Civil Buildings" stipulate the following regarding waterproofing in kitchens and bathrooms: 6.12.3 Floors in bathrooms, toilets, kitchens, and other areas frequently exposed to water or non-corrosive liquids should use waterproof and non-slip surface layers, and should be lower than adjacent floors, with a drainage slope towards the floor drain; bathrooms and other building floors requiring waterproofing must have a waterproof isolation layer; the floor structure must use cast-in-place concrete or precast concrete slabs, with a concrete strength grade not less than C20; except for door openings, the perimeter of the floor slab should have a concrete edge with a height not less than 120mm. Floors frequently exposed to water should be lower than adjacent floors or have thresholds or other water-blocking facilities, and should have drainage measures. These floors should use non-absorbent, easy-to-wash, and non-slip surface materials, and should have a waterproof isolation layer. The "Code for Acceptance of Construction Quality of Building Ground Engineering" stipulates the following regarding waterproofing in kitchens and bathrooms: 4.9.3 For building ground engineering requiring waterproofing, the joints between risers, sleeves, floor drains, and floor slabs must be sealed before installation, and a concealed inspection should be conducted; the drainage slope should meet design requirements. In summary, waterproofing in kitchens and bathrooms is a crucial aspect of construction work, directly impacting the user's interests. Only by strictly adhering to the specifications can leaks and rework be avoided.
