Cleaning the water tank


Tomo3090

Recommended Posts

I am wanting to freshen up my water tank after our trip and I wondered what to use. I was going to use "Milton Fluid", but to buy enough to clean a tank, even as small as ours, (45 litres), would cost as much as the van did!

 

Does anyone know where you can "bulk buy" or is there something else I could use?

I bought something called Puriclean from my local caravan shop. Cost me £5, and there's enough to treat the system twice. Also bought some tablets to put in the tank every time I fill it to keep the water sweet.

I have heard horror stories about Milton, not sure how many are true. One of them suggested that neat Milton will eat its way through a stainless sink overnight, so beware if you use it. I've also heard that it wil make a mess of your Truma boiler.

Hi,

 

Go to your local home brew shop and buy the cleanser for wine making equipment (it used to be SDP Chempro but that has now been superseded). It is safe on aluminium and stainless steel, the materials that may be danaged by either Milton or Puriclens, and more importantly it is safe if you ingest it or the residue of iti.e. foodsafe.

Our tanks had been cleaned by the previous owner using Milton and then we used Puriclean a couple of times. I think they are both based on the same chemicals. We could never get rid of a strange smell to the water as it came out of the taps. And I had trouble with the Puriclean, I didn't dissolve it first and it all got clogged in the inlet pipe. Horrible stuff, I think. Then I discovered you shouldn't put it through the Truma and since our system automatically pumps water into the boiler, this is not good!

 

Have now discovered (through reading previous posts on this forum) that Certisil is the stuff to use. I used it for my spring cleaning session, and since then the water from the taps has been smell free at last.

 

It comes in liquid form and although not cheap, it will last for a good few cleanouts.

 

Get it from www.myriad-products.com or we bought it at a show.

I've actually given up on worrying about the taste of water from my inboard tank. When I use my 'van I fill it and empty it a couple of times so that it's had a good flush through. (I'm fortunate that I've a sink in my garage and a long hose so it's an easy business to fill it.)

For drinking water we use two or three (depending on how long we're away from a supply) of the plastic milk bottles from Tesco, which hold four or six pints (I can't remember off hand!). These, thoroughly cleaned, make excellent compact water carriers and again, I'm lucky that in my 'van there's a convenient place to slot them.

We only use the inboard tank for washing and teeth cleaning and all drinks come from our separate supply in the plastic bottles.

Once every year or so I may put a bit of Milton through and it doesn't matter if that leaves a slight taste as we're never going to be tasting it!

The wine bottle cleaning jollop is Sodium Metabisulphide. Used to use it quite a lot when we were into home brew wine.

Try Boots or your local independant Chemist. (I try to not use Lloyds because they seem to be driving all the independant Chemists out of business, They did ours!)

Cheers people! We don't use it for drinking either, but I just felt it might be a good idea to keep things "fresh"!

 

The heater thing might be a problem though, any ideas there?

 

Do you clean your teeth with it though?

 

Your reference to heater thing, do you mean that it has been known to damage some, if so use the wine making stuff as recomended by myself and named by Clive (thanks Clive couldn't remember what SDP was made from) as it is safe for use in your heater and whole system in the van without any worries at all. We've used it for years and it is what was recommended in the Carver instructions for use as being suitable.

I have to state, you chose your words well. The ideas you wrote on your encounters are well placed. You made some good points there. I did a search on the topic and found most people will agree with your opinion.

We have used the same approach as Caraprufe for the last decade or so at home and abroad.

 

Drinking water is kept in recycled milk bottles and the local municipal treatment of wherever we are keeps the livestock in the main tank under controll. Before a trip I fill the tank about a third full, go for a drive to swill the tank and leave for a day or so then drain and refill just before leaving.

 

The 2 litre ex milk containers have a handle and are a handy size for pouring and storing. We use a half dozen giving about tw or three days between refills for the two of us.

This topic has been done to death but here goes again.

Never cleaned a tank on any of my caravans boats or Mh. Clean our teeth, make ice and drink it and never had any ill effects. I just drain the tank if its being left more than a few weeks.

Same here.

 

Life's too short.

 

Have never "cleaned" our freshwater tank. Cannot see the point.

We don't even drain it in between tours. Just fill it up with a hose from the house supply just before leaving for our next tour.

 

Our drinking/cooking water is bought en route as bottled water (every shop on Spain/Portugal/France etc sells the 5 litre containers).....we carry about 3 of those big bottles as a time.

We just use one of those little bottle-top manual pump jobbies to decant it into kettle/saucepan from the in-use bottles location on the floor opposite the kitchenette.

 

We do wash up, shower, and clean teeth with the tank water......and astonishingly we haven't died from that process as yet.

By far the easiest stuff to use is beer line cleaner. Custom made for the task, and thousands of people can swear by its effectiveness!

 

Ask in your local - they may sell you some or get you some.

(and you can have a pint when you're in there!)

 

From memory (but don't quote me) , about £8.00 for 5 litres which will last forever.

Having previously posted on this forum that I used Milton fluid I was advised that I was doomed, doomed and that my boiler would become a colander. Been a few years now and it is still in one piece however I have just stopped cleansing. Although a bit out of kilter at the moment I never waste water as it is such a valuable resource. Those that drain off after every trip have little time from me for this total waste as there is absolutely no logic.

I had suffered a lot with awful tasting water from the holding tank and put a posting on here probably about a year ago, various suggestions were made and a lot of folks just didn't understand why I was too tight to go out and buy gallons of bottled water, however one kind soul PM'd me and told me of Elsil, it is nothing short of fantastic, the downside is I have only found it on line.

Here is a link to the Milton Fluid Data sheet

 

http://www.milton-tm.com/hres/milton%20fluid%20safety%20data%20sheet.pdf

 

Section 8 is the relevant part. They are talking about undiluted fluid in contact with metals for extended periods.

 

When I used to make parts for nuclear reactors any substance with chlorine in was not allowed anywhere near the stainless steel stock or parts for the reactors as it could eat in to the steel during the life of the reactor.

 

So there must be some wisdom in not using any liquid that contains chlorine to clean water systems that have metalic parts.
