Water tank pressure relief valves are discussed here at WATER PUMP & TANK SAFETY. At Relief Valves - Water Heaters we discuss temperature and pressure relief valves used on residential water heaters. For a general discussion of temperature and pressure relief valves used as safety devices on heating boilers and other pressurized please see Relief Valves - TP Valves. Pressure relief valves (that sense pressure only, not temperature) are also required on pressurized tanks such as water tanks in buildings.

PUMP & TANK SAFETY - Water pump and water pressure tank or water storage tank safety advice

While you're on the topic of water pumps, tanks, and controls, here are some safety tips about water pressure tank relief valves and electrical safety around this equipment.

• Trip hazards wet floors can cause slips and falls - be careful.
• Electrical shock hazards: can be fatal. Do not touch electrical controls in a building, such as a pump power electrical switch, if you're standing on a wet floor.
• Fatal Electrical Shock Hazard if you remove the cover of the pump pressure control switch (discussed above at ADJUST PUMP PRESSURE CONTROL) you can get access to the two nuts that adjust the operating pressures of the water pump. But watch out! There are also live electrical contacts exposed in this area. If you touch them, especially being near water piping, there is a serious risk of death by electrocution. Watch what you touch, or have a professional plumber or electrician do this job for you.
