Hello.

When I checked my KHD today I noticed some odd measurements and went to check on the machine.

All hoses where filled with water and I couldnt empty them. Found out that the waste hose was placed in the drain. Probably beneath waterline. Pulled it up and the machine was able to empty as normal.

My question.

IF the waste line was below surface of my drain would that mean KHD siphoned water from the drain inside the KHD and then also back into the aquarium?

Feeling nervous about this.
