1. If it is caused by improper decoration by the upstairs user when decorating the house, the upstairs user will pay the maintenance fee.
If the structure of the house itself has quality problems, and the house is still under warranty, the developer will pay for the maintenance. If the house has exceeded the warranty period and requires the house to pay the house maintenance fund when handing over the house, then the owner can apply for the house maintenance fund to pay the maintenance fee.
3. If the waterproof layer in the upstairs user's home is aged, damaged or caused by pipeline rupture, the upstairs user will pay the maintenance fee.
4. If the user downstairs uses it improperly, causing the pipeline to break and leak, the maintenance fee will be paid by the user downstairs.
Tips: When users downstairs find their own water leakage problems, they should first find out the cause and location of water leakage, and then find the corresponding maintenance person in charge. If the user can't find the cause and location of water leakage, he can ask a professional testing institution to help him with the testing.
Causes of leakage of waterproof layer upstairs
1, the water inlet pipe is leaking. The method of judging whether the water leakage in the upstairs bathroom is caused by the water inlet pipe is very simple: first, we write down the data of the water meter and ask the upstairs residents not to use water for a period of time. After this time period, check the data of the water meter. If the water inlet pipe leaks, it will definitely be reflected on the water meter. Water leakage in the inlet pipe will cause unnecessary waste. You can consider the water fee of the upstairs users and ask the upstairs neighbors to cooperate.
2. The drain pipe is leaking. When testing whether it is a drainage pipe problem, we need to find a water pipe to connect to the faucet so that the water can always flush at the floor drain. Be careful not to let the water reach the ground for 2 hours, and see if the leakage downstairs will increase. Or block the floor drain and drain the water in the bathroom to see if the water leakage downstairs will increase. If it gets worse, it can be determined that it is a drainage pipe problem.
3. The waterproof layer leaks. If there is nothing wrong with the inlet pipe and the drain pipe, we will close all the sluices, drain all the water in the water pipes, and do a 24-48-hour water-closing test upstairs to see if there will be water leakage downstairs. The leakage of waterproof layer is a troublesome water leakage problem, so it is necessary to knock off the floor tiles upstairs and make them waterproof again. Therefore, in order to avoid this situation, the owner should do a good job in waterproofing, standardize construction, and conduct three closed water tests at the beginning of decoration.
Solution to leakage of waterproof layer upstairs
1. If the problem is the water inlet and outlet pipes, then considering that the water pipes are underground, the original tiles need to be planed off. If the water inlet pipe leaks, it can be replaced by an open pipe, and the leaking water inlet pipe can be discarded. If the drain pipe leaks, it is necessary to find the specific location of the leak, and then replace the water pipe accordingly.
2. If the waterproof layer on the ground is damaged, the lighter can repaint the brick joints on the ground with waterproof coating. It is better to remove the original tiles and waterproof layer, re-make the waterproof layer and re-paste the tiles. The waterproofing of the ground and wall can be completely removed and renovated as a whole; You can also tear down the ground. Only two bricks on the ground were removed from the wall, and the part below the two bricks was waterproof. In general, the shower area wall is below1.8m, and the non-shower area wall is below 0.9m.. Before you finish waterproofing the ground, you must do a 24-hour closed water experiment according to the national requirements. Splash water in the bathroom at home, and then look at the same place downstairs to make sure it doesn't leak again.
Of course, the solution of the above three problems is based on the complete understanding and cooperation of the upstairs users. If we can't negotiate with the upstairs residents on the grounds of water leakage in the upstairs bathroom, we must be rational. We can sue each other according to relevant laws and order them to solve the problem as soon as possible, but we can't take drastic measures. Otherwise, not only will the problem not be solved, but it will also increase our troubles.
