Water Supply Regulators -Water Saving Devices

Water supply regulators save 1/3 of the quantity of water that flows through the tap without our even noticing it.  The regulators allow for a steady and economical flow of water and are easy to install - simply screw it in.


Water Supply Regulator for the Kitchen Tap

This regulator allows for a steady flow of water from the kitchen and bathroom sinks.  There are two types of regulators:  a line regulator installed between the wall and the tap and an end regulator installed on the end of the tap, instead of the regular water filter that does not save water.  After installation of the water regulator on the sink tap, water flow will range between 4 and 8.5 liters per minute.


Water Supply Regulator for the Shower Head

This regulator allows for a steady flow of water through the fixed and hand-held shower heads.  The regulator is installed by simply screwing it in before connecting the shower head or between the battery הסוללה and the handheld showerhead pipe.  After installation, water flow will range between 8 and 11 liters per minute.


Water Supply Restrictor for the Sink Tap

This device reduces the diameter of the water pipe and thereby reduces the supply that flows through it to the sink tap.   It is installed simply by screwing it on the opening of the tap, instead of the water filter which does not aid in saving water at all.  After installation the water flow will range between 3.2 and 10 liters per minute.


Economical Shower Head

This  shower head features a water supply regulator or restrictor.  The quantity of the water used with the economical shower head ranges between 4.5 and 11 liters per minute.


Economical Hand-held Shower Head

This  shower head features a water supply regulator or restrictor.  The quantity of the water used with the economical handheld shower head with a water supply regulator ranges between 4.5 and 11 liters per minute and the quantity of the water used with the economical handheld shower head with a water supply restrictor ranges between 4.5 and 13 liters per minute.



Taps with Automatic Shut-off Valves

This is a tap operated by pressing or pulling on a button, which closers automatically after use or after a set time.  There are two types of taps with automatic shut-off valves:  a drinking tap that supplies water as long as the button is pressed and a sink tap that supplies a set amount of water, which allows you to use both hands to wash dishes.


Taps with Automatic Opening and Closing Valves

A tap operated by a system of electronic sensors, without the need for manual operation.  The tap works as the sensors detect hands approaching the tap and automatically close when the hands move away from the sensors.


A Garden Volumetric Valve

The 1” or ¾” garden volumetric value - enables a planned allocation of water supplied to irrigate the garden.  The volumetric valve automatically opens and shuts the water flow based on the predetermined time and quantity of water.
