Many people who decorate themselves may forget the operation of closed water test, which often leads to a lot of hidden water leakage hazards in their bathrooms, and may cost more money in the later stage. The closed water test is the last step in waterproofing, and the tight plugging of the sewer nozzle will be the most critical step in the closed water test.
Because of its importance, I don't know what to plug the sewer pipe in my house, why? Because I didn't expect to do a closed water test at the beginning, the sewer pipes have been cut and ready to be tiled, and the nozzles are only plugged with simple rags to avoid clogging the gravel and cement falling into the sewer pipes during construction. When the neighbor came to the door, he immediately stopped me and said:
Have you done a closed water test? Are you so confident in your skills and eyesight, and you're not afraid of leaks? ”
Well, admit that I don't have that much confidence, so I cleaned up the tools on the bathroom floor and made the bathroom into a "big container" ready to waterproof, and the neighbor reached out to stop it: "Don't you check your sewer plug?" And it's better not to use a cloth plug.
One is because the cloth will absorb water, which will affect the effect of the closed water test, and the other is because the cloth is very difficult to stuff and difficult to find, so the simple and easy way is to find a plastic bag filled with water, provided that the plastic bag is not leaky.
Use the pressure of water to plug the sewer pipe, which is easy and easy to operate, or it is also feasible to replace the water with yellow sand, which is the most common material on the construction site, unlike the cloth and the special belt, and even if it is used in the process of laying bricks in the later stage, it is also used more sponge, and its cleanliness is better. Have you done a closed water test at home?
Just find some fine sand or dirt to use outside – just clean up after the closed water test!
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.
After 24 hours of waterproofing, the water will be closed, and the water level at the highest point of the plane shall not be less than 2 cm. The entrance is built with a waterproof edge. Acceptance after 24-48 hours of water closure.
The bathroom did not do a good job of waterproofing, and in principle, it had to be smashed and redone. There is an economic loss for sure, and it will be higher than the cost of renovating the bathroom for the first time, because the master in the industry would rather take the work of decorating the rough house than taking the work of repair. As for the damage to the structure of the house, as long as the construction is reasonable, the use of electric hammer instead of real hammer will not cause damage to the structure of the house. >>>More
The bathroom must do a closed water test, because it is easy to cause water leakage if the waterproof is not done well. If you live downstairs, you will be unlucky. The closed water test should generally be done after doing a good job of waterproofing, and now the floor tiles are pasted and then done, if the water leaks, the floor tiles can only be dug up. >>>More
