The waste hose through which the water is removed from my washing machine is inserted into a vertical pipe extending from the floor with a U shape at its end.
The problem is that there is foam coming out of the pipe where the waste hose is inserted.
Can I extend the pipe that is after (above) the U to leave more room for the foam to form and hopefully prevent it from overspilling?
Is there a height limit ?
If the hose can reach 1 meter above the washing machine, does it mean that it is safe to have the hose connected so high?
Is there a danger of causing damage to the washing machine's water pump that pushes the water outside if it has to push a water column that is too long/high ?
