The tiles on the kitchen hose cover are leaking

1Is all your house the top floor?

If it's the top floor, it could be due to the following reasons: ruptured sewer pipes; The waterproofing of the air pipe connected to the roof surface is not done well, and there are gaps; leaking exterior walls;

If it is not the top floor, and there are residents on the upper floors moving in normally, there is only one possibility: water seepage on the exterior wall at the corner.

Cracked sewer pipes need to be repaired by smashing tiles; Roof leaks just need to be redone on top of the waterproofing; The water seepage on the exterior wall should be found in the property and repaired outdoors, but the leakage point is difficult to judge, and it is difficult to smash it open to see, but the cost is all from the developer.

You're right, it's the exterior wall that's leaking! The main thing for you now is to find the leak point, and it will be much easier to find the source treatment!

Normally, the caulk and glass glue turn black, which is mildew, and the main reason is moisture.

Why is it damp, and there is water seepage, it is because:

When the temperature of the sewer pipe wrapped by the tile is low and high, it will affect the temperature of the tile surface, resulting in water vapor condensation in the kitchen.

There are two conditions for condensation:

The moisture content of the air is large;

Temperature varies greatly.

Generally, it is easy to appear in places with good thermal conductivity, sharp protrusions, large temperature fluctuations, and poor air circulation.

So don't worry about it for the time being, on rainy days, just turn on the range hood more often and close the windows tightly. If the darkening is more severe, it needs to be treated. It's best not to wipe it with a wet towel, the more you rub it, the darker it gets.

When you say water seepage, is it only in the place where the sewer pipe is wrapped, or is it all on the front wall?

Is the tile of the water pipe full of water seepage or local sporadic water droplets?

The water pressure of the sewer pipe can basically be ignored and should not leak.

It could be the exterior wall, it could be the flue coming down from the roof, and if you're on the top floor of your house, there's a good chance that the water on the roof is also very likely.

First use a quick-drying waterproofing agent to plug the exterior wall and then leak, and then it is not too late to knock bricks.
