Why should I test my water?
Unlike other water systems found in homes and commercial premises where the water is flushed or drained away after each use, swimming pools, hot tubs and spas could be considered as a re-circulating water system where the water is retained and re-used many times over.
If you’re not testing the chemical and microbial water quality regularly, taking steps to maintain balance and keep it clean, issues such as pH and water clarity can change, and more worryingly bacteria can start to grow rapidly.
Am I legally required to test my water?
If you are running your swimming pool, spa pool or hot tub as a ‘commercial entity’ then UK health & safety law requires you to carry out microbiological water testing. This includes any holiday property that is let to paying guests.
How often should I test my water?
Pools, Spas & Hot Tubs should have a microbiological water sample taken on a monthly basis.
Spa pools and Hot Tubs are required to be tested on a quarterly basis for Legionella species.
