Upstairs bathroom drain pipe leaking

If there is a leak around the water pipe and prefabricated slab, a 2 x 3 cm groove needs to be cut around the pipe mouth. Then wash it with a brush dipped in water, and finally fill it with CF-2000 high-efficiency composite waterproofing agent, and smooth it with calendering. If the pipe elbow interface is leaking, it is necessary to customize special plugging fixtures and supporting plugging materials.

Don't damage the pipe structure, it will be easy to leak.

As long as you plug the leak. Generally, it can solve the problem, because if the upstairs is not a cistern, there is usually only a small amount of water in part. Therefore, there will be no diffusion of water seepage on a larger scale.

This may be the water used in other places downstairs from the ground tile joints seepage, and then from the root of the pipe, to be upstairs to lead people to repair, not downstairs maintenance, more information, better advice, free concrete waterproofing and leakage water repair technical advice, to avoid today's repair, tomorrow's leakage, every year repair, every year leakage troubles.

The current drainage pipe, in the middle of the floor, is generally a straight pipe, the joint or the head bend inspection port is downstairs, the material is PVC, generally not damaged by external force, and there is rarely damage and leakage, because there is no water pressure, and the joint gap is rarely a problem. But it doesn't mean that there is no problem, you can try it, for example, if you want to flush upstairs, the drainage pipe is divided into a fecal pipe and a sewage pipe, which is separated, the fecal pipe is specially connected to the toilet, the sewage pipe is a ground drain, the washbasin, you see which pipe is seeping water, flush which pipe, if you flush (at least 5 minutes) you can see the water coming out of the drain, it is likely to be the water pipe. If it's a water pipe, in your home part, if it's visible, small damage can be repaired with glue, you ask the plumber and they can fix it.

Breakage is rarely seen in the middle of the slab. If it is the position of the joint, it can be cut off and replaced with a new one, and the current drainage pipes are connected with glue, which is still more convenient.

There is also a possibility that the nozzle is seeping. It is the joint between the water pipe and the floor slab, because the material is different, the thermal expansion and contraction coefficient is not the same, the waterproof is not done, or the waterproof is damaged, the water under the tile is easy to seep down from the gap. It is characterized by water flowing down slowly without flushing, and white crystalline calcium carbonate.

In this case, it is best to do the nozzle waterproof from upstairs, and it is recommended that it is best to chisel the floor of the bathroom to make waterproofing. If the upstairs does not agree, the situation allows, and the nozzle can also be waterproofed from the downstairs.

In the picture, it is the water seepage at the nozzle, not the water pipe itself.

The water pipe on the far left seeped water, the upstairs did not agree, and we blocked it from the downstairs for the owner.
