What sort of a drain pipe is this

drainpipe

I dont even know if drain pipe is the right word. We have this little pipe jutting out of the wall in our back yard.

It keeps dripping water. Its a new unit/apartment in Australia and the builder is now no where – so we are on our own.

First we thought it was the water heaters outlet, because the builder said so. But the water dripping out is cold. Then we noticed it will only drip when our washing machine is draining its water into the trough. Clothes washed with cold water. Doesn't look like all of the water is getting out either, but only a glassfull.

1) Should we be worried about it ? 2) How do I fix it.

If you only notice it draining when the air conditioning cooling unit is on, my guess would be it is the condensate drain for the evaporator coil.
