Mouls in water pipes

see if you can get some pipe that wont let light into to it,the light is what causes
the algae to grow. cheers

how about painting them

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

I use air hose on my caravan comes in Yellow, Blue and Blue/Yellow
On the small line 1/2 black dripper tube also works, use that from tamk to pump suction line, I use air on pressure line

Yeh replace the clear pipe with non transparent, It's the light that does that ,get a clear plastic water bottle and solid color bottle and half fill them and leave them for a few weeks and see the result

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

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

Thanks guys.

Heaps of good answers here and ideas. I will give them a go over the next few weeks with good results I am sure.

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.

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:-).
