I changed the toilet sewer pipe, how often to test the water

About 24 hours later. After the waterproof coating is painted to form a waterproof layer (about 24 hours later), the water storage is 20 high, and after 24 to 48 hours, see if the water is significantly reduced or go downstairs to see if there are wet water spots on the roof, and if not, it means that the waterproof construction is successful.

The specific method of waterproofing the bathroom is as follows:

1. Use cement mortar on the ground to find a slope in the direction of floor drain, but the surface should be smooth. The slope near the entrance is small, and the slope near the floor drain is large.

2. The pipeline passes through the root of the floor slab and near the floor drain to strengthen the waterproofing. The pipe root building sealing paste is tightly sealed, and the cement is smoothed after the foot guard, and when the waterproof coating is brushed, the glass wire cloth is reinforced with 1 or 2 layers.

3. The wall is clean and flat, without floating ash and small particles, and the small original corner or slope angle is wiped at the junction of the wall and ground. When brushing waterproof coating, paste 1 2 layers of glass wire cloth reinforcement.

4. The total thickness of the polyurethane waterproof coating film is required to be more than millimeters. It can't be decided by the number of passes. Brush the root and corner reinforcement layer first, dry the surface at room temperature for 4h, and then paint and scrape the area of Dayou Qingsale.

There shall be no leakage and bubbling. Brush a large area for 24 hours and then apply the next layer after curing.

6. The waterproof layer on the ground should be painted 300mm wide outside the door of the bathroom. The waterproof layer of the waterproof ground should be 200mm higher than the ground.

7. Do a 36-hour closed water test as required. Hope.

After the bathroom is waterproofed, it needs to be thoroughly dried, so that it can do the closed water test, you can contact the residents downstairs in advance, so that the leakage can be informed in time to avoid unnecessary losses of the downstairs residents When doing the closed water test, the depth of water storage can not be less than 20 cm, and the time can not be less than 72 hours, and the water level does not fall is qualified.

This can be done in a few hours.

If you have glue, try it in 24 hours!
