FREQUENTLY ASKED QUESTIONS ABOUT LOW PRESSURE TAPS:

Especially in the bathroom and kitchen, a faucet is used every day intensively. Therefore, it may be necessary to change your tap after several years of use. Besides, you may simply want to change your faucet to get access to new technologies or to adopt a style that suits you better. Whatever the reason for replacing your mixer, before choosing a new one, you must know from which system your hot water is coming. When is it necessary to choose a low-pressure basin tap or sink faucet? What is the difference between a low and a high-pressure mixer? These are the questions this article answers.

WHAT ARE LOW-PRESSURE FAUCETS?

There is no difference between the appearance of low-pressure faucets and high-pressure taps. However, the design and operation are different. The low-pressure faucet is used when hot water comes from an instantaneous water heater. In this case, two connections are made to the boiler and one is required for the water supply so that we have three connections instead of two. When the hot water lever is open, cold water flows from the water inlet to the tap. From there, it goes into the water heater at a lower pressure where it displaces the hot water, which is driven to the tap through the third connection and is distributed in the desired hot and cold mixing ratio. The tank of the water heater fills up as the hot water is withdrawn. By using a low-pressure tap, only a small portion of the pressure is released into the boiler. Due to their more complex design, low-pressure valves are more expensive than high-pressure models.

This picture shows the difference between low pressure fittings and high pressure fittings. Low pressure fittings use hot water from a boiler.

WHEN DO YOU NEED A LOW-PRESSURE MIXER?

It is used in decentralised hot water supply, i.e. when an instantaneous water heater or the hot water tank is used. Since these cannot withstand the pressure of normal water supply, a low-pressure mixing valve is absolutely necessary, otherwise, the instantaneous water heater tank may burst when water is forced through it at high pressure.
