Is there a problem with the crooked toilet drain pipe?

1. Not necessarily.

2. The flush toilet has a drain device. >>>More

Now it is common to use PVC drainage pipes, which are convenient for construction and not easy to block, and the only drawback is that there is a sound. Fortunately, it can be installed on the ceiling, but the ceiling can not be completely soundproofed, you can use old cotton clothes to cut into strips, wrap the pipes on the ceiling, and build the riser with bricks, so that although it can not be completely soundproofed, but the sound will be very small, please accept it.

As long as there is no leakage downstairs, it's fine, install the toilet first, the pipe leakage is repairing the pipe, and the toilet will not be dismantled for maintenance, even if the repair is repaired downstairs.

In some commercial buildings, the balcony only has a roof underwater pipe, and there is no reserved indoor sewer pipe. >>>More

It is best to advise you to find a professional to deal with it. The leakage of the sewer pipe building is mainly because there is no water-stopping rubber ring when installing the sewer pipe, I don't know if you can still install it now, our family later pried the bricks around the sewer pipe, and then cleaned up the small stones around the water pipe, and then sealed it with cement, and then made a layer of waterproof after drying, remember to brush it thicker, and finally paved the bricks, and filled the ditch sealant, and now it has not leaked.
