High Pressure Water System (Type 1)
If you have a hot water tank (cylinder), usually found in your airing cupboard, but you don’t have a cold water tank (cistern) in your loft or
garage, this is an unvented high pressure system.
This can look similar to a low pressure system so check carefully to avoid confusion. Also take caution in refurbished houses with disused
water tanks.
If you have this high pressure systems all product sold by Premier Taps are suitable.
High Pressure Water System (Type 2)
If you have a Combination (Combi) boiler
which heats water on demand so there is no
hot water storage cylinder or cold water tank, you have a high pressure system.
If you have this high pressure systems all product sold by Premier Taps are suitable.
Low pressure gravity fed water systems
If you have a cold water tank (cistern) in your loft and a hot water tank (cylinder) in your airing
cupboard, this is a gravity-fed system. It’s the most common household plumbing system and means you have a low pressure water system.
Having low pressure need not limit your choice of tap or shower. If your hot water cylinder is large enough, simply choose from our extensive range
of Low Pressure (0.2 bar or below) products.
If your hot water cylinder is large enough and you a tap or shower that requires 0.5 bar or above, it is possible to boost
your system with a pump.
