How high the inspection opening on the toilet drain should be from the ground

1 meter, the upper and lower error does not exceed 20 mm.

The national water supply and drainage engineering acceptance code stipulates that "an inspection port should be set up every other layer on the drainage riser, but an inspection port must be set up on the lowest floor and the highest floor with sanitary appliances, the center height is 1 m from the operating ground, the allowable deviation is 20 mm, the orientation of the inspection port should be easy to maintain, and the inspection door should be installed on the inspection port on the concealed riser".

Generally speaking, the toilet drain should be inspected more than 1 meter from the ground.

Summary. Hello (How high should the inspection opening on the bathroom drain be from the ground?) 1 meter, the upper and lower error does not exceed 20 mm.

The national water supply and drainage engineering acceptance code stipulates that "an inspection port should be set up every other layer on the drainage riser, but an inspection port must be set up on the lowest floor and the highest floor with sanitary appliances, the center height is 1 m from the operating ground, the allowable deviation is 20 mm, the orientation of the inspection port should be easy to maintain, and the inspection door should be installed on the inspection port on the concealed riser".

Extended Materials. Toilet drainage.

And by lowering the toilet floor or raising the toilet floor surface layer, an intermediate layer is produced between the two, and the toilet interface, the bathtub interface air trap box, the sink interface air trap box, the floor drain air trap box, the dredging box and the transverse connecting pipe are buried in the middle layer. The current drainage pipe of the upper toilet passes through the floor slab, and the form of connection and assembly is completed in the upper space of the lower floor, which solves the various contradictions caused by the repair of the drainage pipe blockage, water leakage, and floor seepage.
