Wondering if anyone uses anything to flush through supply and waste pipes after or before a period of no use?

I`ve used this for over 6 years now :- http://www.cleantabs.co.uk/puriclean.htm

CARAVAN CAMPING PURICLEAN 400g WATER TANK & PIPE CLEANSER | eBay (http://www.ebay.co.uk/itm/CARAVAN-CAMPING-PURICLEAN-400g-WATER-TANK-PIPE-CLEANSER-/171120949088?pt=UK_Campervan_Caravan_Accessories&hash=item27d79a7760)

Hunt around i`m sure you`ll find it cheaper.

My Tank and Pipes are spotless and we drink the water from the Tank without any problems at all.

So how do you use it? Flush the pipes through with it? Leave it in the tank for a set time etc?
Yeah I did think about Milton as well.

If you use Milton be very careful of the strength that you mix it. Too strong a solution damages Stainless Steel (it should tell you on the bottle). Follow the instructions. You don't want your boiler falling apart.

Follow the instructions and make up the solution as required for the size ( litres ) of your tank.

Then run the taps for a short while until the mixture is in all the pipes and taps etc. and then close them so the solution stays there.

Leave for your desired time ( between 1 and 12 hours ), i leave mine overnight.

Empty the tank and run the taps and then fill and flush the tank and taps a couple of times with clean water, job done.

1 X 400g tub does mine twice, i use it approx every 6 months and it works well for me and keeps everything spotless.

Do you use the Aquatabs as well Wooie?

Hi there.

No we don`t use the Aquatabs, but we are quite particular / fussy about the water that we put in the tank.

Used to be puriclean for us but since fulltiming we don't bother as the water is constantly replaced, if you don't like products as such white vinegar is really good if you use quite a strong solution it will also descale the boiler without the risk of causing any harm to the stainless steel tank, Truma used to recommend it's use before they came out with their own products. I personally wouldn't use Milton as it can harm the boiler tank and can leave a nasty taste and smell, some people believe that it causes some chemicals to leach out of the plastic pipework, despite what the data sheets say.

I don't pretend to know the in's and outs of the plastic hose business but what I do know is that most of the problems with the unwanted taste and odour seems to have started around 2004 onwards and as a manufacturer of various types of motor caravans and specialist vehicles for the fire and ambulance services etc we noticed a difference in the food grade pvc hose that we were ordering, it was a lot stiffer for a start , maybe the make up of plastic was different to what we were using before but it was around this time that we found people having problems after using Miltons and if I remember correctly so did several major caravan manufacturers, as we also used almost exclusively Truma boilers who also don't recommend the use of Miltons etc we had to advise our customers not to use it. just came across this ;
A simple thing like "TCP taint" in drinking water is actually very complex and involves a series of interrelated events and genetic predisposition.

Flexible plastic tubing is flexible because it is dosed with a plasticiser during manufacture - different plastics use different plasticiser compounds - but if it's for food grade tubing they will all be passed safe by an independent authority.

Under certain circumstances - minute amounts of plasticiser can leach from the tubing - but it usually doesn't taste of anything and people don't notice. And by minute I mean the equivalent of one part in a million - much less than say one speck of sugar in a one kilo bag of Tate & Lyles finest...

But then things can go wrong: If the owner uses an Oxychloride steriliser (like Milton and many, many other sterilising solutions) under the wrong conditions (acidic water) to sterilise the pipework, or if emergency pipe work in or around the camp-site has just been carried out and the water authority has used point sterilisation - then small amounts of free Chlorine can be released into the water - and this reacts with any "loose" plasticiser to create a Chlorinated compound that has a taste remarkably similar to TCP

And to add a bit more complexity, there is a genetic predisposition to detecting this "TCP taint" - it's at remarkably low levels in the water - and many people just don't notice it, a few people can, and a very few (like me and I guess Pete in a post above) are ultra-sensitive.

So if you are one of the many - it doesn't matter what you use to sterilise the pipework, doesn't matter if the pipework is dripping plasticiser - you won't taste it, won't be even aware of it, and you'll happily write "I do this and no problems" on an internet forum
If you are one of the few - then injudicious use of Milton tablets can screw up your pipework for weeks or months unless you literally pump gallons of water through it.

And if you are one of the very few - then a point sterilisation of water authority pipework outside the camp site can (and did one year in France) cause the irrevocable contamination of our whole water system - but if you aren't susceptible to the taint, you wouldn't even notice it - but I can still taste it four years on.

So we always use a 2 litre water jug for drinking and cooking water - and sometimes if the camp site has plastic pipework and was "zapped" with Chlorine years ago, we need to buy bottled water from a supermarket.

And then there's the off-taints from mould and algae growing in stagnant water, but if it tastes like TCP - then it's Chlorinated plasticiser

Many years ago on boats I used to used puritabs and similar products but for years I just use water lots of it. In many respects really sterile water is not good as t actually makes you more vulnerable to bugs. I use only potable water sources to fill my tanks and have no problems, though tend to use my own hoses and connecting devices whenever possible

I do it this way except I usually leave it only for the time recommended on the bottle, and certainly no longer than an hour, never had any problems.

I think you`ve slightly misunderstood me.

The instructions are for Puriclean which is a powder and comes in a tub.

They say to leave in for between 1 and 12 hours as per the website and the label on the container.

We just take the waters wherever we are !. But, if referring to that non-alcoholic water based stuff, we just fill the tank & drink wherever we are, from Stornoway to Sarajevo. We once used used weak Milton in our system, 7 years ago, tasted horrible. Never cleaned tank., pipes etc, since & not had any problems.

Cheers for that, yes thought you meant Miltons, doh.

Hi Rodeo,

We use Sodium Hypochlorite tablets as recommended here :- Zappysblog for practical articles and tutorials on motorhome water hygeine, tank cleaning, tank disinfection tablets,cleaning water tanks, image tutorials choosing a mobile satellite system and more. (http://zappysblog.co.uk/) , bought from Graham as well.

That's what I use. I tried to find a link like you did but could not manage it, so well done. :wave:

AGREED... For that reason we have only ever used Milton on the waste water side.

we only have the removable 25 ltr water containers, and use Sodium metabisulfite from my old brewing days,


oh but don't breath it in especially if your asthmatic.

I keep something similar for the water containers, they only need treating before our first trip as they are used a lot after that.

I always use Elsil an Elsan product developed for passenger aircraft fresh water tanks you can even add a few drops when topping up with water from unsure areas as well as using to flush and clean all tanks,pipes taps etc not a bad price as well, very safe to use and no taste

Well my original question has generated a whole host of opinions! Due to a dicky stomach after drinking dem foreen waters a few yrs ago, we always buy bottles of water to drink.We will only use the on board system for washing/showering. The whale type submersible pump and all the pipe work is brand new, so Im hoping to keep it that way with somesort of sterilisation.

Has anyone used the pressure drainer (I think it is called floe) that uses a tyre type valve in the water system to let you empty all the pipework ?

It seems to claim to clean the pipes as well ?

As far as I have ever read Floe is only designed to remove all water from the system by Air Pressure

I believe that the pressure is only 1 or 2 bar.

We just give the system a good flush. When we come home we do the same with the house plumbing for the drinking water but we don't bother with the hot water system. We are careful of what we put in the tank though. We carry bottle water in case we do have to use slightly suspect water, doubles as a backup if the tank runs out.
