Overview
Australian Valve Group (AVG) PTR25-1000-LF 25mm (1") 1000kPa PTR Pressure and Temperature Relief Valve (also known as TPR valve) is Australian Watermark approved and intended for commercial hot water service applications, with a high kilowatt rating of 132kW.
Pressure and temperature relief valves, known PTR valves are critical mechanical safety devices for all hot water services. The temperature sensing probe monitors the hot water service's temperatures. AVG PTR valve temperature probe is covered in a Teflon wrap to prevent any calcification build up overtime and to ensure long term accuracy. Inside the AVG PTR valve body, there is a piston mechanism that opens according to the pressure inside the water tank.
During the operation of the hot water services, the volume of the water will expand during heating cycles, as cold water heats up. This increased pressure can be dangerous if not regulated. The PTR valve regulates the pressure slowly dripping the water out of the tank in a controlled manner, usually via a discharge pipe into a drain or ground. Therefore, when the slow dripping is observed, it is just a perfectly normal PTR valve operation.
When there is a malfunction with the heating component or the thermostat in a hot water service, an uncontrolled heating can be extremely dangerous and explosions can occur catastrophically. PTR valve can detect this when the temperature and pressure exceed 99 deg or its preset pressure ratings. In this case, PTR valve will fully open and dump hundreds of liters of water to relieve the water heater tanks. The Kilowatt rating of the PTR valve refers to the rate that the PTR valve can dissipate this energy and this is regulated by Watermark and plumbing codes in Australia.
When a high kilowatt PTR valve rating is required in a commercial installation, a smaller sized 15mm or 20mm PTR valve must not be used as a cost cutting method for safety reasons.

Activist history
Format: Hardcover
Anderson quite thoroughly explodes the myth of the rampant voter fraud claims that fuel the actual problem of rampant voter disenfranchisement, particularly aimed at non-whites. And, by extension, Anderson explodes the myth of the United States being a free and open democracy and shows us how much we still have to do to live up to the national image some of us like to think we put out to the world. From the illegal purging of voter registrations, to gerrymandering, to voter intimidation, Anderson offers up the facts of the racist policies that look to keep elections in the hands of white patriarchy and suppress its opponents. While Anderson sometimes resorts to some typical metaphors in her rhetoric (false comparisons to Stalin, for example, or Orwell name drops) that could too easily be cherry-picked by dull-minded opponents looking to poke holes in an otherwise fine case of what should be enraging us into action.

You will never look at voting the same again.
Format: Kindle
A well written, easy to understand, and eye opening book which details the problems with our current political system and the efforts to control the vote in order to keep the power and the money in the hands of the few. Well worth reading and will shift your view of voting and the difficulties many of our citizens face.

A must-read for every American
Format: Hardcover
This book is a must-read for every American. It starts as a historical lesson about voting rights and how they have evolved and devolved over the years and ends with a very detailed real time discussion of current voter suppression, gerrymandering, and election fraud. The greatest lesson I learned from it is that our voting experiences are absolutely determined by our zip codes. It is extremely relevant to what is happening today and in our very recent past. This book should be required reading in every high school and college American History, Civics and Government class un America.

excellent
Format: Paperback
Detailed look at the many voter suppression efforts that target communities of color and the poor. The rationale is partisan and simple: a majority of the country doesn't agree with Republican politics. In order to stay in power, the GOP is using seemingly neutral laws that in reality disenfranchise many voters, particularly African Americans. The GOP has manufactured solutions in search of a problem, all in an effort to stop non-white people from voting. It's incredibly pernicious but Carol Anderson has written an excellent book pulling back the curtain on voter suppression.
