Waste Pipe ... What's it's purpose?

[odbguy]

There's a waste pipe on the underneath if my engine. ..
sometimes it drips other times ****es water after the car has been driven ...
I have checked all the levels etc and nothing seems low or to change. .. i ***umed it was possibly from the aircon, but it drips/****es regardless of use.
Iv tried looking on the net but not had much look.
Wondered if anyone could please advice me on its purpose and if it's a problem.
Any feedback will be appreciated. Ta

I'm not sure, but I think it's attached to a pan that collects all the condensation from the Air Con piping and then it all runs out of the pipe as you say. Sometimes, climatic conditions depending, it will drip more than other times.

It does sound like the aircon condensation outlet, but odd that 'water' runs out even when the aircon is off.

And another thing... how come every other f****r on TA can now swear like a c**t, except me?

 

[odbguy]

Haha I had to get my gf to check where I swore. Sorry about that

Cheers both for you answers .. I ***umed it was probably connected to the aircon but as you said Jon, odd that it drips even when aircon not been used.
Would you say that it's likely to drip even if just had the normal heating on and not the actual aircon??

Mine does this, came out of a service station last week and thought it was ****ing oil across the car park but it was just water. I have checked levels and its all fine. So I decided it must be the AC and I'm not worrying about it.

The heater being on wouldn't cause it. Maybe condensate collects in a tray and can't all get out at once... some stays behind when the a/c is turned off and splashes about so some continues to come down the pipe well after the a/c is turned off?

 

[Stevearcade]

Just testing: ****es

Edit: well, maybe ****es is a borderline swear

**** s**** *****

2nd Edit: the rest don't get through, it's all good

 

[odbguy]

Haha ****es is all good!!

Nice one cheers very much for replies ... I thought it was nothing worth worrying about but it's worth asking just incase

I would think that it's coming off the evaporator: even when the compressor is not running, I guess that moisture can still condense onto the evaporator when the weather is humid (the weather in this country is actually quite humid, which is why low temperatures feel colder than they actually are)

edit: Honda actually call it "climate control", which is different from ordinary A/C, in that "climate control" removes moisture as well as keeping the temperature at a stable level by adjusting the cold and warm air flows. Even with the compressor not running, the system will be using a cold air-stream (from the evaporator) to mix with the warm air-stream (from the heater). So there will almost always be an airflow over the evaporator

Ahh thanks Freddo, well explained il educate my dad over the weekend cos he was asking about the drip too ..
glad I asked this question and didn't just ignore it! Lol

^ mind you, having said all that, are you sure it's not from the waste pipe for the front guttering i.e. rain-water or screen-washers
