Tip & How-To about Garden
The thermal relief valve is a valve that opens when the water inside your pump gets too hot. When you are not pulling the trigger on your gun, the water is circulating inside the pump. After a little while the water starts getting hot from the friction of the moving parts. When the water gets too hot, the heat starts to damage the water seals. What a thermal relief valve does is, at about 145 degrees it opens up dumping the water inside the pump on the ground. As the water pours out, new cool water flows in from the garden hose, cooling off the pump. I personally recommend a thermal relief valve to everyone I sell pumps to. Not all pumps come with a thermal relief valve. For the price (between 10 and 15 dollars) they will save you a lot more than they cost.
