Water in clear hose pipe connected to boiler

[Trac]

Is there always water left in?

The water is clear – if it’s waste why is the water so clean and clear?

I see few of these maybe 1 a year so others may disagree.
Boiler should have a solid plastic pipe from it to a small pump and the clear pipe in your photo will come out of the pump (this is discharge side). This clear pipe will sometimes go up a wall a maximum of around 4.5m and eventually join the drains. This clear pipe should not go downwards and then go upwards again (important bit) and yes this pipe will have some water in it. Although it may look clear I wouldn`t drink it.

This is really helpful so thank you very much for taking then time to answer my questions. It’s so clear I wouldn’t think it was discharge – as you mention this should join the drains – as far as I can see it all goes downwards and at no point does to turn and go upwards. Very very helpful and puts my mind a rest! Thanks you very much

.....so are these plastic pipes not so common then? And why would they be used as oppose to another type of pipe of different material?

Hi
It's because th waste water ( condensate) from your boiler is very corrosive to metal.
