You will get a larger yield of spirit if temperature fluctuations are kept to a minimum. This is achieved with a constant cooling water flow. This can be difficult if family members are constantly flushing the toilet or putting the dishwasher on while you are distilling. Now you don't have to worry! This latest Still Spirits product is here to help you perfectly control your water flow when using your still. We have designed your own small water supply especially for your still. Connect this device to your tap, let it fill with water, and you have a reservoir of water for your still. The Water Flow Regulator includes: - Its own built in pump to supply water to your still. - A float valve to regulate how much water it holds. - A water flow controller, so that you can set it to the exact flow rate for your needs. - A cool reservoir to store up to 1 L of water.
