In this episode of Waterfall, Mike and Karen chat with Andrew Tucker, Demand Reduction Manager at Thames Water, about one of the biggest hidden sources of household water waste: leaky toilets. They discuss how modern dual-flush toilets leak internally without people noticing, how a single leaky loo can double a household's daily water usage, and what smart meter data is revealing about continuous leaks across thousands of homes. Andrew also breaks down why internal mechanisms fail and how upcoming regulations, like Defra's mandatory water labeling, aim to fix the issue on a national scale.

In this episode of Waterfall Rapids, Mike and Cath explain why the water pressure drops or the water goes off when it's really hot. It's not because there isn't enough rain - there was plenty over winter and spring. The real problem is that when it's hot, everyone uses much more water at once, and the pipes and treatment works can't keep up. They talk about how companies can get ready for this, why saving water all year round helps, and why South East Water brought in a hosepipe ban - not because of drought, but because their network couldn't cope with demand.

In this episode of Waterfall Rapids, Mike and Karen are joined by Natasha Wiseman, founder of Make Water Famous, a positive news platform dedicated to connecting people with water in all its forms.

With child drowning figures having doubled in recent years, Matt explains what is driving the rise, what the Water Safety Code is and how to follow it, and why more than half of all drowning fatalities happen in inland waterways rather than at the coast. The episode also explores the broader message of respecting water in all its forms, from open water swimming to water conservation.
