Use our handy guide to understand your plumbing system and calculate water flow.
The best way to check your pipe diameter at the intended point of installation is with a Vernier measuring caliper.
As a rough guide, 15mm pipe is approximately the same diameter (width) as a 5p coin,
whilst 22mm pipe is more similar in diameter to a 20p coin.
* Please note, this method is intended as a guide only and assumes metric pipes. If in doubt consult a qualified tradesperson.
Follow the steps below to calculate your flow rate. Use our handy calculator below to avoid the maths part entirely.
Place a bucket under a tap and turn the cold water on full blast. Important: note the bucket's volume in litres.
Time how many seconds it takes to fill the bucket to the brim. Ensure you don’t have a flow restrictor fitted to your spout or system.
Divide the volume (in litres) by the number of seconds, so if it took 15 seconds to fill a 5 litre bucket do: 5 divided by 15 = 0.333
Then multiply this figure by 60 to calculate the number of litres per minute: 0.333 x 19.999, or 20 litres per minute.
