If you drain your pool to carry out repairs the cost to both you and the environment can be enormous.

A swimming pool measuring 4 metres by 6 metres with an average depth of 1.75 metres contains a staggering 42,000 litres of water!

By draining off all that water the cost to the environment is huge - you then have to re-fill the pool and add the chemicals, yet more cost to you and more damage to the environment.
