A cycle is when the tap is turned on after sitting idle for greater than 2 hours. You can count or estimate how many cycles exist per day and  x 7 will give the weekly figure. Enter your data in "By-pass water Recovery Cycles per Week" column

To calculate the actual water loss,  measure the amount of water you would normally let run down the drain before the hot water arrives to the supply outlet, using a measuring  jug and bucket. This is the amount to enter into the "Litres Recovered" column for each individual recovery

Enter your actual figures in the yellow areas
