Installation of the drain pipe for the temperature and pressure relief valve?

It is the drain for the Temperature and Pressure relief valve (T&P valve, or TPV). It's function is to release pressure from the water heater if the pressure or temperature of the water exceeds preset limits. Do not cap off the pipe, or remove the T&P valve or alter it in any way. Doing so could cause serious injury or death! If you notice water dripping or running from the pipe, call a plumber to check it.


What is difference between pressure reducing valve and pressure relief valve?

pressure relief valve relief the excess pressure which is developed in the syatem, while pressure reducing valve reduces the pressure and supply it to the system.


Difference between Thermal relief valve and safety valve?

A thermal relief valve is a liquid-only relief due to expansion of a liquid with increased temperature.A safety valve relieves pressure due to a gas.It should be noted that "safety valve" is a general term which could refer to Pressure Relief Valves (PRVs) or Pressure Safety Valves (PSVs), terms which are used synonymously in some industries (such as the petroleum industry) to refer to all relief devices in general.


Is it normal for water to leak out of the pressure relief valve on a hot water tank?

YES, as a hot water tank should NOT have a relief valve it should have a combination of Temperature and Pressure relief valve. Normally a T&P is SET @150 PSI and Or 210 Deg F. If the valve leaks this is a sign of an impending disaster such as a pressure vessel exploding. A professional will check to make sure (NBBI, ASME, LMP,) 1- The pressure is not exceeding the high limits of the system 2- Make sure the aqua stat is actually functioning 3- The pressure temperature relationship of the system is not exceeded


How do you size a boiler relief valve?

The relief valve should be at least as large (in BTU/hr capacity) as the input of the boiler. A 3.5 million input boiler would need then a relief valve to handle at a minimum 3.5 million BTU/hr.

What is a tell tale on a relief valve?

A tell tale on a relief valve is a small opening or connection that allows excess fluid to escape when the relief valve opens. It is used to visually indicate when the relief valve is relieving pressure and discharging fluid. Tell tales are important for monitoring the performance and functionality of relief valves in a system.

What is Difference between relief valve and safety valve?

Relief valve always position in the suction line in oreder to relief the extra pressure, while safety valve is always placed at discharge line to release excess pressure.I would take that one step further by stating that a " RELIEF VALVE" is one that is "meant" to be lifted off its seat, as opposed to a "SAFETY RELIEF VALVE" which is not!DIFFERENCE BETWEEN RELIEF VALVE AND SAFETY VALVE:1. Releif valve is applicable in the fluid system.safety valve is applicable in the gaseous system.2.Relief valve opening is directly proportional to the pressure rise.Safety valve opening is will happen at after reaching the setpressure.3.Mode of relif vlave line is again connected to the suction.But in the safety valve is just vent-out there is no connection tosuction.
