Get great water flow (and more joy) from your gravity-fed rainwater tanks with full-port valves

Brad Lancaster shows you how the valve choice (and hose size choice) for your gravity-fed (free gravity is your only “pump”) rainwater tank makes a big difference in water flow.

The better the flow, the more you’ll happily use your free harvested rainwater, instead of other imported waters that you have to pay for via a utility bill, a pump, and/or power costs.

The key is to make it more convenient and more joyful to do the right thing, while also reducing costs and complexity.
