Basin basin drainage height is generally how much
The problem is not clear, refers to the water pipe out of the ground from the wash basin outlet height or refers to the water pipe into the wall on the wall out of the height of the wash basin outlet? The former, then the height should not be too high, with a hose to connect the wall can be connected down, so there can put some things, too high can not put things, inside the other pipeline is not easy to repair when the failure, if after Of course, naturally high is better, from the wash basin outlet 10 cm or so is not higher than the outlet just fine
