How Clean Tabs Products Can Help You

Clean Tabs has made a detailed study over many years of the problems associated with small scale water storage in boats, caravans, motor homes and coaches. The deterioration of water quality when stored and contamination of the water storage system, requires specialised treatment to be effective.

Clean Tabs have developed a range of products, specially formulated to care for the many aspects of stored water. The following information gives an explanation of some of the problems encountered and the products to use to avoid them.

Stored water must not be taken for granted

Pure water is essential

Safe drinking water is essential to good health and a continuous supply is vital to the human body. The water we drink must not contain any concentration of micro-organisms, parasites or any other substance which constitutes a potential risk to human health. It is also important that water used for domestic purposes i.e., washing, brushing teeth, cooking, making ice and washing fruit and vegetables, ids of equally high standard.

Availability of water

Suppliers of public drinking water in the UK ensure the safety of supplies by disinfection and treatment of the water at source and through the supply network. The quality of public water supplies is usually assured and is available on tap in almost every building. Modern practice is that drinking water is taken directly from the mains – not from storage.

Away from a public supply

When cruising in boats or touring in caravans or motor homes away from a home water supply, a continuous supply of water is still essential for drinking and domestic use. Water must then be carried in a storage tank or a container and usually piped through a low-pressure water system to taps and other outlets. Water may be stored for days or weeks and may be refilled from various, and possibly dubious supplies. When water is transferred from a good mains supply into a storage tank, it will deteriorate in quality and contaminate the storage tank and water system if not treated.

Good water storage practice

Water transferred from a public supply into a water storage system will deteriorate to unhealthy levels unless preventative measures are taken. Transfer the water from the public supply in a container or via a hose, used especially for that purpose and disinfected periodically with Puriclean or Puri Sol.

Dangers of Water Contamination

Water contamination

Strict water quality standards derived from the EU Drinking Water Directive ensures that “water is free from any micro-organisms and parasites and from any substances, which in numbers or concentrations, constitute a potential danger to human health”. Because water is a very good natural solvent, depending on the water source and other factors, water can contain small quantities of dissolved and suspended particle, but the greatest concern of water suppliers is the danger of pathogenic micro-organisms.

All public water supplies are disinfected, treated, and distributed under pressure through pipe work where it is most unlikely to sustain pathogenic bacteria. However, when water from a public supply is transferred into a water storage tank, a completely different situation arises which adversely affects the water quality.

Never take stored water for granted.

Water stored in a tank or container is exposed to an ideal environment for growth of micro-organisms and will deteriorate in quality unless treated. The deterioration will become more rapid if initially the tank and water system is in any way contaminated. It is possible for untreated water to contain many organisms, for example:

  • Bacteria
  • Fungi
  • Protozoa
  • Algae
  • Viruses
  • Spores
  • Cysts

Biofilms – the real danger

Bacteria within a water system attach to inner surfaces, cracks and crevices, and secrete a slimy glue-like matrix biofilm. Bacteria within a biofilm will utilise available nutrients to multiply, enlarging the biofilm which releases bacteria into the water passing through, creating further biofilms in the water system and infecting the water. Biofilms are resistant to many disinfectants, and so it requires specially formulated products to remove the biofilms and eradicate the bacteria within. Use of these formulations with a ‘soak and disenfect’ action is proven to be hugely effective.

Tastes and odours

Tastes and odours in water – musty, earthy, plastic, metallic, chlorinous – can originate from the public supply network, but more often from within a water storage system. Causes can be – bacteria, biofilm, fungi and leaching from metals. Pheno; leaching from plastic pipework is a common cause of unwelcome tastes and odours. A disinfectant increasingly used in public water supplies to remove tastes and odours is available for use in the form of:

Puri Sol to eradicate bacteria and remove tastes and odours in water storage tanks and systems.

Aqua Sol to treat and eradicate taste and odours from water.

System 1

Aqua Mega/Midi/Mini Tabs should be added to the water when filling or refilling to ensure that the water is free of harmful bacteria and to keep it fresh. It is essential that the water system is completely cleansed and disinfected by a specialised product at the beginning and end of each season. Puriclean is a special formulation for this purpose and is a simple process of soaking 1-12 hours to clean and disinfect.

Aqua Mega Tabs

Rapid dissolving effervescent tablets for treating stored water. Each tablet purifies 225 litres of water.

Aqua Midi Tabs

Rapid dissolving effervescent tablets for treating stored water. Each tablet purifies 25 lts of water.

Aqua Mini Tabs

Water purifying tablets. Each tablet purifies 1 litre of water.


Cleans and purifies all stored water systems in boats, caravans, motorhomes and coaches

System 2

Bad tastes and odours occur in stored water often from bacteria, metals or phenols leaching from plastic pipe work. Aqua Sol is a solution like that used in public water supplies which disinfects and removes tastes and odours leaving fresh tasting water. Puri Sol is specially formulated to clean, disinfect and remove odours from the water tank and pipe work by soaking 1-12 hours. Use at the beginning and end of each season.

Aqua Sol

Purifies water for drinking and eliminates tastes and odours

Puri Sol

Cleans and purifies water tanks, removes biofilms, kills micro-organisms and eliminates tastes and odours.

CAUTION: do not mix systems 1 and 2 because this can nullify the purification process.
