Water seepage in the bathroom damps the downstairs walls and floors

The responsibility for this question lies first and foremost with you. If the water leaks downstairs, you are liable for compensation. Before you renovate, the developer has done waterproof treatment, it depends on whether you have damaged the original waterproof layer during the renovation process, if it is damaged, then you can't find a developer.

If there is no damage, then you can go to the developer to recover your losses. The state has provisions on waterproofing treatment in the regulations on the completion and delivery of residential buildings.

Then this problem is a problem of building quality, and you should check this problem with the developer. If it is not solved, there will be endless troubles.

Alas, it's been so long since the house was delivered, and most of the responsibility lies with you. It is recommended that you find a professional to visit your home.

The responsibility should be yours, it's your water pipe that is broken!

It must be your responsibility, waterproof is just prevention, you do this, more than 60 tons of water, the home is not goldfish porcelain, your kitchen, bathroom is waterproof, so you have to go to the living room, hehe!

This is a big deal, and depending on the situation, you can't face this responsibility.

If you had done a waterproof test at the time, it would have been fine.

Anyway, I know that when you hand over the house, the property should be responsible for repairing the leakage, you can go to the property and ask.

This responsibility is, of course, the property's.
