Anonymous users2024-01-24Do you do a closed water test for secondary drainage? Is it to do a closed water experiment at the caisson position of the secondary drainage, or to do a closed water experiment after the prefabricated slab is overhead and the sanitary ware is installed? If it is to complete the surface to do the closed water test, it is not good to do, if it is the secondary drainage caisson position to do the closed water test is necessary to do, basically 24 hours or 48 hours test, and then check whether there is water leakage in the downstairs floor, it must be done, if not to do can not be accepted, the real estate property will not be accepted.

Anonymous users2024-01-23There is nothing bad about the closed water test!
Their so-called water leaking into the water pipe is extremely irresponsible and unprofessional (the national code clearly stipulates that waterproofing requires two closed water tests). They are worried that the drain will leak, take a strong plastic bag of water, and tie it tightly, can't it? Even a renovation worker will have a way to do a closed water test.
They will definitely help you do waterproofing for secondary drainage (you see if there is in the quotation, if not, they may be malicious leaks or too unprofessional), do a good job of waterproofing must do a closed water test, closed water test is generally done twice, brush the waterproof floor tiles before doing once, 24 hours downstairs observation no leakage is qualified, the second time is the floor tiles are pasted after the floor drain is installed, the same 24 hours downstairs observation no leakage is qualified.
In addition, I would like to remind you that you look at the warranty period for waterproofing in their contract, and the national standard stipulates that the waterproof warranty is five years.

Anonymous users2024-01-22You have already done it when you received the house, so you still have to do experiments when you do waterproofing with the decoration company, and you have to do it when you finish it, no matter what, as long as it is waterproofed again, you can find him within 5 years! Nothing to worry about! It's the same with or without a contract, as long as you can prove that he decorated it for you!
If you have a renovation contract here, then it's even more fine!

Anonymous users2024-01-21The closed water test is very simple, plug the door with sand, plug the floor drain, put the water on it, and go downstairs for 24 hours to see if it doesn't leak. Just do it yourself.
It must have been before the bricks were laid.

Anonymous users2024-01-20The decoration company is obviously lazy which rough room decoration bathroom does not have water pipes to do the experiment is the construction specification because to observe 24 hours so the decoration company is not willing to wait You have to strongly ask to do it Otherwise it is very troublesome to go wrong in the later stage When the closed water experiment is accepted, you must also invite the property company to come or the owner downstairs to confirm so as not to have problems in the future.

Anonymous users2024-01-18The closed water experiment is something that every family must do, otherwise what to do if there is a problem in the future, it must be done.
The closed water experiment must be done before laying the floor tiles, and after the floor tiles are laid, if there is a problem, how do you fix it?

You can use JS, polyurethane, Cao Yangbao, Jintang water does not leak, plugging king, South Korea Shuangxiong, the dry area is 300 high, the wet area and the adjacent wall of the bedroom study are also 1800 high, waterproof and do over the threshold, the root of the wall is rounded, the pipe is flanged, the water is removed after the 24-hour water storage test without leakage, and then a layer of mortar protective layer is made, and finally the wall and floor tiles are pasted.

The ground floor drain is a primary drain, and the underground floor drain is called secondary drainage. Because the toilet drainage is generally discharged through the floor drain, but there is also water that will seep directly into the caisson from the floor tiles, day after day, more and more water in the caisson, if the secondary drainage is done, the caisson can be successfully discharged. >>>More
1. Open holes and install drainage pipes. We first need to make a hole in the main drain pipe in the bathroom, and then install the drain pipe. The mouth of the drainage pipe should be the same height as the original sunken layer waterproof layer, and the other end should be inserted into the main drainage pipeline, and the PVC glue should be used to bond firmly. >>>More
Put the prepared sand in a plastic bag and plug the floor drain to prevent the water from escaping. Plug the door where the water may be full, and the ground is very low. >>>More
Secondary drainage is a drainage method to prevent leakage of water pipes buried in the bathroom and water seepage from the floor to the owner's house downstairs. Because the toilet will leak into the caisson in the case of long-term use, and then accumulate in the caisson, the cement will more or less leak downstairs in the long-term soaking, and the secondary drainage just solves this problem. When decorating, the owner should pay attention to the water pipe laid in the room and it is best to seal it with asphalt, so that even if the interface position is not completely sealed during construction or has been used for a long time, it will not leak. >>>More
