What is the difference between an air bleed valve and a pressure relief valve on a boiler?
They serve two different purposes. An air bleed valve is used to remove air from the circulation system. A pressure relief valve is designed to automatically open when certain pressure levels are reached.
Do you have a problem your well Water Pump Pressure Control Switch is making a lot of noise and you have a lot of air in your water lines?
You need to switch off the pump, drain the pressure tank and fit a new pressure switch. They are cheap and often last only a few years. When re fitting make sure the pressure tank residual pressure is about 2 PSI LESS than the pressure switch ON setting. In most domestic wells systems the pressure switch comes ON at 30 PSI, so the tank air should be 28 or so..
What effect will blocked flue have on the boiler?
The combustion air will not be able to go out the chimney. Since it has to go somewhere it will leak out the boiler into the boilerroom. If the boiler is air tight the pressure inside the boiler furnace will become high enough that the air will surge or run backwards out the forced air fan. This could lead to combustion outside the boiler, explosion or at least filling the boiler room with smoke and poisonous gasses. The flue on our gas fired hot water system once became jammed shut. It was the smell of incomplete combustion that alerted me to a problem. If it had happened when everyone was asleep or no one was home, the house would have filled with carbon dioxide.
Radiators are cold on second floor source of heat is a oil fired boiler?
The fuel does not matter, it would be more relevant to post if you are hot water or steam, that is where your problem lies. If steam try raising the boiler cutout pressure a little bit and if hot water look at the boiler pressure, does the pump work, is the coupling broken and do you have air in the system that needs to be bled?
Why would the air conditioning compressor on a 1999 Chevy Cavalier not come on?
Low on freon, faulty pressure switch, faulty clutch. Jumper the low pressure switch with a paperclip (can running, AC on), if the clutch cycles, it's either low on freon, or the low pressure switch is bad.
Symptoms of faulty well water pressure tank?
The pump will switch on frequently. This indicates lack of air in the pressure tank which is the most common problemThe pump will switch on frequently. This indicates lack of air in the pressure tank which is the most common problem
What is an air pressure switch used for?
An air pressure switch would control the air pressure in any machinery that relies on air pressure for functioning. These switches can be found in any industrial facility.
Where is the 2004 Chevy Impala air conditioning pressure switch?
The 2004 Chevrolet Impala air conditioning pressure switch can be found on the end of the air conditioner compressor. The pressure switch should be labeled as such.

Where is the ac low pressure switch on a 1994 trans am?
The 1994 Pontiac Trans Am air conditioning low pressure switch is on top of the air conditioner compressor. The low pressure switch will be labeled as the low pressure port.
How to drain a radiator in the house?
Not for the faint of heart! For a Combi/Evaporation boiler: Switch off the boiler. Take a reading of the boiler water pressure gauge. Shut off the radiator's thermostat valve(if fitted)/supply valve and return valves, connect a hose to the drain and put the other end into a large container below the level of the bottom of the radiator. Open the draincock first and then the air bleed valve and let the radiator drain. Close the draincock. When refilling the radiator put the anti-corrosion treatment in first then open the thermostat valve and return valve as wide as possible. when the air is expelled, close the air bleed screw. Using the fill loop restore boiler pressure. Put all thermostat valves(if fitted) to max and fire up the boiler. After the boiler has run for 10 minutes, switch off, or so go to the highest radiator and bleed out the air. WARNING: the water/steam will be very hot and likely to spit. Use a cloth as a barrier and to mop up any spills. Recheck the boiler pressure and top up as necessary.
Where is the AC low pressure switch on a 1997 Pontiac Sun-fire?
The 1997 Pontiac Sunfire air conditioning low pressure switch can be found on the top of the air conditioning compressor. The low pressure switch will be labeled as the low pressure port.
What is the working pressure of air in brake light switch in air-brake vehicles?
The brake light switch is not air actuated.
Where is the AC low pressure switch in a 1997 Toyota Avalon XLS located?
The 1997 Toyota Avalon air conditioning low pressure switch can be found on the top of the air conditioning compressor. The low pressure switch will be labeled as the low pressure port.
Why would a 1998 grand marquis's air conditioner blow cold air for a couple of minutes then blow hot air?
Could be low on refridgerant or have a faulty pressure switch. The pump has to be running for the air to blow cold. If the refridgerant is low the pump will click on and off and not run long. If the pressure switch is bad it will not sense the refridgerant and do a similar thing. If you don't have access to pressure gauges I would go to the auto parts store and ask them if they can put a can of refridgerant in or buy a kit to do it yourself. If that doesn't fix it you may have to see the mechanic.
What is boiler draught?
The flow of flue gases in chimney due to difference in pressure i.e cold atmospheric air outside and hot gases in chmney is called as boiler draught.
