Today's windy weather - also known as Storm Doris - is a timely reminder just how damaging to your swimming pool weather can be. Surprisingly - its not always just the obvious items such as flying fence panels and falling trees that do the most damage. Most often I get called out because a loose fitting cover has allowed all those finer bits of leaf and other flying debris to blow into the pool. If unchecked, these bits block up swimming pool pumps and make it more likely the pool will be a nice shade of green when it comes to Spring. Check your winter cover fixings and make sure the cover is nice and taught. Empty the catcher basket and see the pump isn't struggling.
