If you do not feel comfortable doing it yourself, ask a plumber or HVAC tech. It is not an expensive or difficult fix. Price of the valve and a service call should cover it. Shut the boiler down a few hours before he comes to allow it to cool a bit before he drains it will help.

How do you test a safety valve of a Boiler?
Raise the pressure in the boiler until the valve relieves and note the pressure at which it does so.
What is the highest pressure safety valve allowed on a low pressure boiler?
I believe that is 15 PSI on a low pressure steam boiler
What is the feed check valve of boiler?
The feed check valve of a boiler is on the line coming out of the boiler it is usually to prevent the water from going back in to the boiler its coming out of so it would build up excessive amounts of pressure which will cause the t&p valve to blow temperature and pressure
How do set the lifting pressure of boiler safety valve?
The lifting pressure is set by turning the adjusting nut on top of the valve.
Reduce boiler pressure from 8kg to 6kg draw a schematic diagrame?
we can reduce boiler pressure from 8 kg to 6kg by providing pressure reducing valve that is PRV
Why is to safety valve mounted on boiler drum?
the safety valve is mounted on the top of drum because, if the water level in boiler decreases a certain value, the temperature gets increased in water drum because of lack of water. So, increase in temperature result in high pressure in steam drum, as the safety valve is designed to withstand a certain pressure, after a cetain pressure, the safety valve is removed by high pressure of steam. this is why the safety valve is mounted on top of boiler drum. +++ Shall we sort out that lot? That answer is wrong. Its only link with water-level is that the valve has to be above the water anyway. If the boiler runs dry the safety-valve will not protect it. The safety-valve is there to prevent the steam pressure rising to a potentially a dangerous level. It is set to open at the boiler's designed working pressure.
How do you set gas pressure on a gas boiler?
To set gas pressure on a gas boiler, you will typically need to locate the gas valve on the boiler and use a manometer to measure the gas pressure while the boiler is operating. Adjust the gas pressure regulator on the gas valve until it reaches the manufacturer's recommended pressure levels. It is recommended to consult the boiler's manufacturer instructions or contact a qualified technician for assistance with adjusting gas pressure on a gas boiler.
On a high pressure boiler the pressure gauge could be graduated in?
2 times the pressure at which the safety valve is set.
Does the heater core have a pressure release valve?
no pressure release valve
What is the function of back pressure valve in Boiler feed pump?
The function of back pressure valve is to prevent back flow to the pump in case there is an obstruction on downstream side of valve.
How boiler feed valve works?
There are automatic boiler feeder and manual feeds and depending on the desired working pressure required that would determine the "SET" pressure of the feeder
How is boiler spring loaded safety valve works?
when the pressure increases over the maximum allowable working pressure of the vessel, the valve will open to protect against overpressure.
