Problem:

Institutions are obliged to flush water to prevent bacteria build-up in shower heads frequently and keep very hot water in the water pipes due to the Legionella problem, minimizing the risk significantly at the end points can save flushing and water heating costs.

Legionella is a parasite bacterium , disinfecting the water system does not prevent the growth of legionella in the shower head. In order to prevent the development of the Legionella bacteria we must continue to disinfect the shower head when water flow stops.

Hospitals and Hotels are required to perform an examination to detect Legionella in the bathing water, If the bacteria is detected at a concentration higher than the permissible the institution is committed to perform an expensive process, which can lead to a loss of time for maintenance personnel, lawsuits, Temporary closure of hospital rooms, evacuation of hospitalized patients or evacuation of hotel guests.

Low levels of chlorine, accumulation of scale and organic material in the shower head create an ideal environment for Legionella.

Legionnaires' disease is a hospital acquired disease!

Legionella's existence in private water systems as well. The estimated size of the market is tens of billions.

Unique Value Proposition:

We offer a solution with continuous disinfection much better than all the existing products on the market, Instead of an excellent Legionella shower head filter that usually clogs up after a few months and needs to be replaced at a cost of about 40$, we offer a product based on UVC Led unit with continuous disinfection that is not required such maintenance at significantly lower costs. 

We developed an UVC MVP and began a pilot in our first hospital.

 The patent claims are very wide, we got the patent for the principle that safe shower disinfect the water when the flow stops.

Patent number WO2018116291 

A number of hospitals and a number of hotels have expressed willingness to purchase the product after the pilot.

Solution:

Solution: A shower head with a tiny disinfection unit that is able to disinfect the stagnat water. Safe Shower patent for the solution is by sealing the endpoint for air entry by duckbill valves and then the stagnant water can be easily disinfected continuously with UVC LED unit. 

The invention basically allows for any disinfection unit to operate in a place where it has not been able previously. We prevent the entry of air, thus allowing disinfection units to operate continuously, simple and smart. 

When air is prevented from entering the to the shower head when the water stops by the use of Mini silicon valves, we minimize exposure to aerosols that transmit the Legionella, minimize chlorine oxidization, and minimize formation of scale and organic sediments.

competition:

1.Filters in shower heads: the good ones require expensive maintenance, and with high purchase costs 160$ per year, and a decrease in water flow. The best Legionella shower head filters that usually clogs up after a few months or weeks needs to be replaced and decrease water flow.

2 flushing. https://www.radacontrols.com/media/gl4dlnzb/rada-spa1-sports-shower-panels.pdf

We argue, why waste water and energy used to heat the water being flush, add a simple disinfection unit and duckbill valves that create a closed system, In this way, you can disinfect the shower all the time and solve the legionella problem in showers.
  The flushing also does not provide a continuous solution, between each flushing there is the fear of a renewed reproduction of the legionella bacteria, through continuous disinfection we can treat the legionella problem much better.
3. Auto-Drain  https://www.chicagofaucets.com/autodrain

Regarding the solution of Auto-Drain, there are several problems with it: A. There are still drops of water that are attracted to the pipes through capillary forces, the water drops remain there for many days. Legionella bacteria will grow better in this environment. B. Every time the water is drained, some of the water starts to dry up, thus encouraging the Scale deposition, an environment rich in scale will also encourage the growth of legionella.Attached is an article that discusses exactly this solution from 2020: https://www.aspe.org/pipeline/pipeline-exclusive-managing-legionella-risk-in-showers/

And the same writer, after talking with us, realized that the solution we offer is better: https://www.pmmag.com/articles/105733-reducing-the-potential-for-pathogenic-growth-in-showerheads
