How important is washer/dryer waste pipe height

[Scarletpimpofnel]

Fitted a new integrated dryer with built in drain hose. The manufacturer specifies a maximum height of 80cm for the drain hose but I can only manage 85cm without several hours work and butchering a few cupboard panels etc.

The argument to stick to max 80cm is that anything more puts strain on the pump. As it's an increase of 6% in head is it really the case that is make or break for the pump?

Should I crack on or will the pump fail sooner rather than later or worse burst into flames?

Any thoughts?

I doubt it would matter that much if its only 5cm, if it were me i would just crack on.

Try it and see what happens. If the dryer chokes, take it out and start butchering.

Personally I'd get these things as low as I could...tumble dryers are useful, but there have been too many cases of issues with them to compromise.

Might it be to do with the volume of water that runs back when the pump stops?

It sounds like a vague 'requirement' which may depend on other factors.
