How does the water feed valve work on a boiler?
The water feed valve adds water to the boiler when needed: If water pressure in the heating boiler drops below 12 psi, the water feeder valve will add makeup water to the system automatically, until it reaches 12 psi inside the boiler.
How do I adjust the pressure on my automatic water feeder?
The screw and lock nut on top of this valve permit adjustment of the automatic water feeder valve pressure (it's normally set to 12 psi). The horizontal lever is a bypass that will send water through the valve on to the boiler at full building pressure (it's normally left "off" in the position shown here).
How do you use a pressure reducing valve on a boiler?
When the pressure reducing valve installation is complete and you are ready to fill the heating boiler, open the cold water fill valve to allow the system to fill until the preset pressure of the valve has been obtained. (Residential pressure typically starts at 12 psi cold).
How do you add water to a hot water boiler?
To maintain the water level in these heating systems, water can be added from the building water supply piping manually by simply opening a make-up valve. A manual valve will simply be a shutoff valve that can be opened by hand to force water into the heating boiler. Automatic water feeder valves on hot water boilers
How do you adjust a boiler feed valve?
To reset the regulator valve: Remove the fast fill lever cap, and loosen the lock nut. To raise the reduced pressure - slowly turn the adjusting screw clockwise until the system gauge indicates the pressure required. To lower the reduced pressure - turn the adjusting screw counterclockwise.

Should boiler feed valve be open or closed?
1. To fill the system, open the shut-off valve upstream of the Boiler Feed Valve. This valve must always be kept open when the system is in operation.
What position should valves be on boiler?
Keeping your hand on the valve, you will hear the water entering the boiler. Watching the pressure gauge, you will see the black needle rising. Ideally the pressure should be 1.5 bar, or the needle should be at the 10 o'clock position.

How do I know if my boiler valve is open or closed?
They turn by 90 degrees, and if the handle is aligned with the pipe, it means it's open. Make sure they are both closed – your system circulates its water, and rarely needs topping up.
How can you tell if a boiler valve is open or closed?
When the handle is parallel to the valve, it is closed, and when it is perpendicular to the valve, it is open.Jun 4, 2020
What happens if boiler pressure is too low?
Boiler pressure is incredibly important because it helps to keep the water in your home warm. If the pressure on your boiler is too low, then your central heating may not work, and if it's too high, then it will be under too much strain and could also be prevented from working.
How do I increase the water pressure on my boiler?

Now in some cases it can only be one tap on the filling loop and in some cases you may need a screwdriver to open a closer tap.
Should filling loop be open or closed?
After use the valves on the filling loop should be closed, the metal braided filling loop removed and the valves capped. The majority of people don't do this so there is always a chance that the valves can be opened accidentally or be faulty.
How do I increase water pressure in my boiler?
Top tip!Switch off and allow your boiler to cool.Double-check that both ends of the filling loop are securely attached.Open both valves, to allow cold mains water into the system (you should hear it)Wait for the pressure gauge to read 1.5 bar.Close both valves, one after the other.More items...
What is the pressure of an automatic water feed valve?
The automatic water feed valve reduces the incoming water pressure from the building supply side down to (typically) 12 psi. That's because the normal in-boiler water pressure, when the heating boiler is cold, is about 12 psi in a normal residential system.
Why is it important to keep the water in a steam boiler?
Keeping the proper amount of water in a steam boiler is a critical function for both safety and to avoid damaging the boiler itself. So on a steam boiler we consider the automatic water feeder to serve as a safety device too.
What is a back flow preventer?
The back-flow preventer makes sure that water from inside the heating boiler cannot flow backwards into the building (and community) water supply. This prevents back-contamination of potable water piping from the boiler should the building water pressure fail.
Does a hydronic boiler use water?
Hydronic (hot water boilers) in proper condition do not normally consume any water. Once the boiler and the baseboard, radiator, or convector piping are connected and filled with water, that same water remains in the system indefinitely.
Is it safe to use a boiler without a water feeder?
Steam heating systems without an automatic water feeder are less safe and risk serious boiler damage should boiler water be lost and should there be no low water cutoff installed on the system. That's why all modern steam heating boilers can be expected to include at least a low water cutoff valve.
Does a hydronic water heater consume water?
In normal use, a hydronic or hot water heating system does not consume any water. Only if there is a leak (or during service) would the water level in a hot water heating system drop and need replenishment. That is an abnormal condition, and one that means the system needs to be repaired.
Do hydronic boilers have a cutoff?
A safety improvement on hydronic boilers that gets around this argument is to add a low-water cutoff on residential hydronic heating boilers (hot water heating boilers). That device, always present on steam boilers, is required by local codes in some jurisdictions for hydronic heating boilers too.
What happens if the pressure of a boiler exceeds 3 bars?
Be careful because if the pressure exceeds 3 bars, the safety valve will remain open and you risk a small flood. If this happens, turn off the water supply to the boiler by closing the isolation valve. If you can't find it, turn off the water supply at the meter and wait for the heating engineer to arrive.
How to check pressure gauge?
The process is simple: 1 Locate the two filling valves. 2 Open one of the two valves completely 3 Slowly open the second valve, watching how the needle (or indicator light system) on the pressure gauge responds 4 Let the needle reach the middle of the green zone (or the marker needle) 5 The needle might stop at the beginning of the green zone without going much further even if you fully open the valve. This is probably because your house's water system is equipped with a pressure reducer, which is essential for some devices ( boilers in particular).The water pressure may be higher or even too high in some neighbourhoods in the lower parts of the city. 6 If the needle stops at the beginning of the green zone, this is enough. 7 Fully close the second valve.Tighten it but not too hard, i.e. without "blocking" it. 8 Fully close the first valve.Tighten this one up as well.
