Water tank, overflow pipe..?

[Jutstar]

I have a 1989 Leisure drive, it has two tanks on board one for fresh and one for waste, which live under the van.

I went to fill it with water today and notced that water was coming out from underneath, popped my head underneath and there is a pipe that comes out of the tank with water coming out of it, it does have a jubildee clip on the end but am i right in thinking this is la drainage pipe and would need a tap connecting to the end?? If so is it the sort of thing i could get from JK.

Thanks in advance for your as usual very helpful replies.

Now - resurrecting this unreplied post as I have a similar question:

I also have a (cak?) leisure water tank in out autosleeper trident (91) with a vent (?) pipe coming out about 3/4 of the way up.
Since we got the van this has had a wooden dowel in the end - however water seeped out from the filler connection to the tank when you filled it up.

I guess the overflow also allows the air to be displaced from the tank when you fill it (or can it be displaced through the pump somehow?) - At the moment I have left uncorked - obviously as the water sloshes round it can slosh out through this pipe (a bit) - but this also leaves it open to possible muck getting in (I could tie it up out of the way and put a bit of sommet over the end I suppose

- any ideas - what are the rest of yours like?

Mikey , water tanks are full of bugs , waste fuel , cause loads of worry , and are truly unnecessary , esp when you have a youngster or more to be health-aware ; get rid of it and use those handy 2.5 litre fruit conc plastic bottles from tesco, hang em from a cup hook by their neckhandle .

What a ridiculous post! A 60/70 litre tank versus loads of plastic bottles, I know which I'd choose. No bugs in a tank if properly maintained, more fuel is wasted by the front of the van! I wouldn't like 60 litres worth of plastic bottles hanging around my van. If your travelling for a couple of months or even a couple of weeks what use are they ? And you would need to find water every day if you only had a few bottles.
If you deprive your offspring contact with bugs, bleaching everything, disinfecting everywhere they will never build up any immunity to life's travails. Haven't you ever drunk water from a stream?
If you are worried about bugs in water fit a nature pure filter then you can fill up from muddy ditches, green canal water etc.

what a load of crap!
what world are you living in?
where do you fill your wonderfull tesco crappy squash bottles from?

there are no bugs in my water tank that are not in your plastic bottles, and my water is cooler and therfore a lot less likely to be contaminated that your 2litre at a time kept in the warm ambient temp of your van.

please do not mislead forum users with incorrect information.

If the pipe is 3/4 the way up I wouldn't have thought that it was an air vent - an air vent should be at the top. See if you can check the top of the tank to see if there is another pipe on the top for venting - if there is you can safely plug the pipe permanently ( it may be an off the shelf tank with various connections for differing orientations).
I would ensure that the filler pipe to the tank seal was watertight though.
If you have a large diameter filler pipe and a vented cap you wouldn't need an air vent. You can then plug the offending pipe.
The water tank that I have on my Merc bus has several plugged pipes due to it being an off the shelf one.

On my autohomes there is a pipe that comes off the top of the tank. It vents and acts as the overflow.
