Water Pressure
Gravity - it is very important that before you purchase your tap you establish the water pressure in your home. If you have a traditional hot water cylinder the pressure will be determined by gravity only. Measure the height from the bottom of your cold storage tank (usually located in the loft) to your kitchen tap - the longer the drop the more pressure you will have.
0.1 Bar = 3 foot head of pressure
0.2 Bar = 6 foot head of pressure
0.5 Bar = 15 foot head of pressure
1.0 Bar = 30 for head of pressure
Key:
LP = Low pressure 0.1 - 0.49
MP = Medium pressure 0.5 - 0.99
HP = High pressure 1.0 plus
Combination Boilers - usually provide a good level of pressure - this is usually between 1.5 - 2.0 bar with an average mains pressure supply coming in to your house.
