Lake Okeechobee, the eight largest freshwater lake in the US, and a paradise of wildlife, was contaminated with aggressive toxic algae. 72 hours after governor DeSantis’ call, a response team of field scientists arrived on site and applied BlueGreen’s Lake Guard® Oxy. Within a matter of days, toxic algae were completely eliminated, and no trace remained in the water. BlueGreen not only improved Lake Okeechobee’s water quality, but provided the means to keep all of Florida’s waterways clean and useable.

If your hot water system was installed by a licensed professional after 2013, then it’s more than likely that you have a tempering valve already installed.  They are a standard part of general hot water plumbing, and whenever plumbers install or replace hot water systems, they are required to fill out licensing paperwork to ensure the rules are followed.

Innovative formulations are used in small quantities to break down algae/cyano into inoffensive and non-toxic by-products such as O2 and H2O

Tempering valves have a life span of approximately 5 years, but you will likely pick up on the fact that it’s not working if it begins to fail.

Tempering valve regulations were introduced to counteract the potential danger from the simultaneous updates made to regulations for hot water storage.  It was discovered and then mandated that to avoid the build-up and growth of harmful bacteria like legionnaires, hot water storage units must be set to a minimum of 60 degrees.

BlueGreen Water Technologies' Net Blue™ technology removes CO2 by treating harmful algal blooms. The technology was tested in Utah's Mantua Reservoir and removed 12,913 tonnes of CO2. This accomplishment is a major step in the fight against climate change.

Signs your tempering valve is becoming ineffective include loss of hot water, reduced hot water pressure or lower hot water temperatures.  When this happens, you may not realise that it’s the tempering valves, but a professional plumber who performs hot water repairs will know what to look for and how to replace them.

In 2013 the Government updated the regulations for Australian plumbing standards so that every home, office or commercial business using hot water is required to have tempering valves fitted.

Here we help you understand what a tempering valve is and what the regulations are by answering the questions we most frequently get asked about them.

Since 2014, Chippewa lake has had to be closed to the public every summer due to toxic algal blooms. In August 2019 the lake was treated with BlueGreen’s Lake Guard® Blue. As the product floats, the natural movement of the water does the mixing and dispersal. 24 hours later, the lake was clean

Most people know that climate change, pollution, overuse, and waste is rapidly diminishing the planet’s water supply but there is another deadly problem hiding in plain sight.Cyanobacteria/blue-green algae, or harmful algal blooms (HABS) are proliferating in lakes and oceans around the world where they swiftly dominate ecosystems killing off other organisms, hampering the delicate balance of life in the environment, and causing devastating economic damage to industries that rely on water.Even more frightening, they release harmful toxins (such as cyanotoxins) that can sicken, or even kill humans and animals.

Did you know that there is a small device called a tempering valve between your hot water system and your tap that keeps you and your family safe?  Or at least – there should be!

Tempering valves are safety devices designed to limit the temperature of the hot water coming out of your tap.  It mixes the extremely hot water that comes directly from the hot water system with cold water from the general water supply to send out water at whatever the maximum temperature the valve is set to.

This dangerous exposure time dramatically reduces to 5 minutes for water set to 50 degrees, demonstrating the safety objective of the regulations.

The element is submerged in the water and responds to temperature changes by expanding and contracting, adjusting the flow of each inlet valve to ensure the set temperature is maintained.  The thermostatic element is accurate to within 3 degrees, so temperatures can vary plus or minus 3 degrees from its setting.

The tempering valve consists of 3 connections: two inlets for the hot and cold water and one outlet for the water after it is mixed.  It keeps water temperatures consistent by using a thermostatic element to control the flow.

Nan Hu is the beating heart of Yo Yang City and the site of its famous annual water festival. A proliferation of toxic algal blooms threatened to destroy the delicate environmental balance in and around the lake. After exhausting every alternative, government officials appointed BlueGreen water technologies to tackle the problems. Within 24 hours of implementing BlueGreens Lake Guard® technology, the lake’s outstanding recovery was clearly visible on satellite images.

Tempering valvehow it works

There are different types of valves made to suit different types of hot water systems.  Most use a colour coded system to differentiate between valve types, however, these colours can vary between brands.

A licensed plumber can adjust your tempering valve if you want to change the temperature it is set to.  Legally, it cannot be lifted above the maximum of 50 degrees, but if you want to reduce the temperature to protect people in your house or business, a plumber can set the valve to a lower temperature.  Most valves can be set between 35 to 50 degrees.  This is not something you can do yourself and requires a professional.

The Lake Guard® Blue treatment was applied to a 6-hectare reservoir in Israel. While it only took minutes to apply the formula, far-reaching results were evident within 24 hours.

South Africa knows more than most countries how critical every drop of water is. Within just a few days, one treatment with BlueGreen’s Lake Guard® solution made billions of gallons of water in South Africa safe for human consumption.
