Sprinklers shower development

The use of the shower is a high proportion of domestic water consumption. Taking into account that the shower use a rate of about 20 liters per minute, and the average time a shower is estimated at 5 minutes, the volumes consumed by shower can be up to 100 liters. This figure would be very worrying if it were not for the fact that there are really very simple options to reduce this amount by up to 50%.

Correct action to reduce the amount of water consumed in the shower should be directed in two ways:

• Limit shower time optimizing water use (close the tap while soaping, avoid long time under water, etc.).

• Install saving technology that reduces the output rate.

Although the technical description of the mechanisms of savings are based on heads telephone showerheads, being the most widespread in homes, all specifications can be applied to sprinklers embedded in own wall of public facilities (locker rooms businesses, sports centers, etc.).

Judging from the location of savers systems themselves, we differentiate between those located internally in the head, and that can be placed externally, as an additional mechanism.

Usually external devices offering fit most of the heads, which reduces in a simple and quick way water consumption. However, usually they have certain rejection by the consumer, since in some cases have a less integrated in the shower design.

Efficient sprinkler Drips n Drops shower

Saving water efficient showers are achieved through different mechanisms that can be combined with each other depending on the model chosen.

Air mixture

One of the most extended options is to mix air with water so that the jet provides the same sensation of consuming approximately half wet water. This measure is often accompanied by an increase in output pressure and droplet size. This effect is known commercially as perlizado .

Reduction of the diffusion area

Usually, part of the water coming out of a shower head does not take advantage properly. This is because, to increase the feeling of abundance and misunderstood comfort, it tends to overestimate the broadcast area. Simple concentration gets outlet jet showers in considerable savings efficient without reducing the amount of useful water per unit area.

Flow Reduction

Reducing the flow, adjusting it to consumer fair values, it is the option that should serve as the basis for any efficient element.

The flow is considered right (at 3 bar pressure) is 10 liters per minute at European level or 2.5 gallons per minute in the United States (approximately 9.5 liters per minute). This flow ensures adequate service and quite away from the 20-liter, this same pressure, offer many traditional shower heads.

When reducing the flow is important to consider that the water pressure is not constant in all facilities, even having variations depending on the schedule.

Therefore, we will classify the flow restrictors as possible adaptation to pressure variations. Thus, we find two main groups: static flow restrictors and flow controllers.

The operation of the limiters static flow is simply based on the decrease in water flow section, thus diminishing the amount of water passing through a point. Generally they work properly usual service pressures (1 to 3 bar), but do not guarantee optimal operating conditions at low pressures. In the market they are recognized only guarantee a certain flow reduction (usually between 40 and 50%) in a given range of pressures, without securing a fixed rate.

There are different commercial presentations, among which the throttles, reducing the flow area by increasing the thickness of the walls of the ducts, and disks with holes in the center graduates. As more advanced option, you can purchase models with interchangeable disks with different rankings. These allow us, at least, an adjustment to the general conditions of our facility.

The flow controllers, more sophisticated than previous ones , but similar in external appearance, behave dynamically depending on the pressure to which they are subjected. They are usually composed of a plastic part shaped ring located at a point where all the water must pass. When the pressure on the rubber is very high, it is tensioned, reducing the water flow, whereas when the pressure decreases, the ring relaxes, increasing the passage section.

Different types of plastic compounds and combination with certain sections allow to guarantee a fixed flow within standard pressure (reaching up to 5 bar pressure).

Some phone showers offer different options from the head itself, launching other systems that also promote water conservation.

Among the most common alternatives highlights the so – called fragmented, which produces a fine dispersion of droplets of water (fog), creating a greater sense of moisture with less flow. This group may also include the jet pulsing or champagne, based on an almost imperceptible interruption of water flow performed repeatedly. In principle function of this mechanism it is to cause a sensation of massage (and well as offer commercially), but indirectly also get a water saving.

External additional mechanisms

As discussed above, there are different options on the market that allow us to reduce consumption without replacing our shower head. The main mechanisms are:

flow reducers. Generally static type (limiters), can be threaded onto the shower hose, both the beginning and the end. In addition, different brands offer their most common models for a number of accessories (disks, reducers, etc.) that are placed inside the shower head, thus eliminating any unwanted aesthetic effect.

Switches water flow. This simple system is placed at the beginning of the shower hose and its only mission is to block the passage of water without having to turn off the faucet. Thus it is avoided manipulate mixture of water (especially in faucets Single – hole), facilitating closing operations at times when water flow is not essential (soaping). There tailored specifically for sprinklers embedded in wall elements.
