Water Testing Good Practice

Testing starts with the sample – from where do we take it?

• The main body of water (i.e. pool or hot tub)
• Ideally mid-way between in / outlets
• Between 100 – 300mm below the surface

 

How do we take it?

• Clean plastic container (never take glass to a hot tub or pool)
• Rinse the container several times
• Make sure you have enough water
• Carry out tests straight away

 

Remember only measuring small quantities

• Equivalent to 1cm on the height of Everest
• Wash and dry hands before commencing (sweat can contaminate the sample)
• Use clean dry equipment
• Make sure you have sufficient sample
• Use suitable location

 

Carrying Out the Test

• Wash and dry hands
• Use clean dry sample tubes or pool block
• Rinse containers several times
• Do not handle the tablets
• Crush tablet using clean dry rod
• Allow time if appropriate

 

After Testing

• Empty and clean all the vials
• Dry all equipment
• Return all tablets to boxes
• Return equipment to box
