Hi all.

The other day after a trip I had need to crawl under my Jayco Penguin Outbacker to fix a water leak near the tank outlet.

I noticed that the water filler pipe (about 1 inch dia) and the smaller 3/8th my water suction pipes were made of that clear beverage plastic.

I also noticed that both these pipes were badly effected from within by mould.

Yucky Pooh's !

Before my wife and I die of some exotic water born mould or disease from our drinking water, does any one have a solution as to how this can be overcome?

Regards

Hi

Yeah I understand that, but to replace the pipes I would had to destroy the seal that goes through the floor, and the only pipe that I know of that would 'really' be suitable is the black poly pipe,and that is by far to rigid to take in any and all bends.

Hi

Now that may be the way to go if nothing else comes up.

The other problem is cleaning the inside of the pipes.

The larger of the 2 pipes, I have managed to buy a small bottle brush that I hope to feed through the piping, but the small hose, I think I will have to make up a sort of 'pull through' as in rifle barrel cleaning, and hope I do not loose the rag half way down the tubing.

Algae is actually not a problem. It filters the water, absorbs nitrates etc.

Actually true... Just the same as the water from a mountain stream tastes clean & pure it's because of the green stuff in the Algae, Chlorophyll, they used to put it in toothpaste as a mouth freshener...This problem happened to me and I naturally panicked and when down the road of Algae destruction only to discover that the plastic taste returned...

Somewhere along the way I was told that in a healthy stream system with a dead animal decaying in the water, it should be clean again with 30 meters or so?

downstream with the flow, point being that micro organisms, plants etc are filtering the water

Speak to a cruising yachtie. They deal with this kind of thing all the time.

I know Bias Boating sell a potable water tank conditioner product.

Janset,

This is a real easy one.

I do a lot of work with the marine industry and one particular vessel I work with fills it's fresh water tank with rain water.
This causes mould and a green algae to grow in the tank and the pipes.

A good dose of bleach or chlorine (about 1 litre per 1000 litres water) and a good flush out fixes the problem.
Same as a swimming pool I suppose.

Hope this helps

David

Chuck a couple of drops ( literally ) of ti tree oil in it, that'll kill and mouldy crap and do you no harm.

Is it possible to slide a larger diameter black tube over the top of most of your clear water hose ? That way you would shield most of the hose from light and avoid changeing it where it penetrates the floor.

An extra layer would also give it a bit more protection downstairs.

Interesting idea that. One could slit a suitable piece of black hose lengthwise with a stanley knife, pop it over the clear tube and tie it up with cable ties.
That would be the easiest fix if it does the trick.

For cleaning this problem they make a product called tank clean you should be able to get it at your local camping store or caraven store from what i understand this product will even take the plastic taste from tanks and lines.

More good ideas.

Thanks guys. The sleeving idea, I have about one meter of that foam insulating hosing used to lag hot water piping. I think the diameter is just about the right size also. If it does not quite fit, I can always spray some of the black rubberised solution that I already have.

I may look at that first as I have always had concerns about stone damage also.

I never had any problems with a plastic taste so far, but I will look into that also to retard growth or just as a general tank clean out.

The correct hose for this type of use is "food grade" plastic hosepipe.
It's available from Caravan & Accessories outlets.

To clean and flush existing tanks & hose, all that should be required is a cup of bi-carbinate of soda.

Yes, after cleaning your existing pipe to get rid of the "Yucky Pooh's" you could paint over it. This may not stop algae/mould/bacteria from regrowing, but you would never see it then:-).
