make absolutely sure the main disconnect is off!! then simply pull down gently and it should pop right out. take it to your local lowes or Home Depot electrical dept and buy an exact replacement. if you have any difficulty with removing it from the main box simply have the salesman at the store show you exactly how to remove,insert and turn off the main. they will walk you thru every step. I advise you to do this first before messing with your breaker. lots of luck. its easy If you are replacing like-in-kind and the existing breaker is the correct one to start with, then the above generally addresses household style circuit breakers that are the "push-in" style. Occassionally you may come across a "bolt-on" style which must be un-screwed from the panel. Breakers are rated in AMPERES, VOLTAGE, INTERRUPTING CAPACITY, and must be listed for use in the breaker panel being used. Listing are by UL, CSA, ETL and a few rare others. Just because it fits does not mean it is the correct breaker. Mis-application of circuit breakers is considered a safety hazard, no different that putting a penny in a old style fuse-holder. Also, there are many other types of commercial breakers and specialty breakers that are more complex, such as GFCI and AFCI.
By turning off the water to the hot water heater. Opening the hot tap to drain the little bit of water left in the pipes. Then you need to replace like for like with the vacuum breaker brand so that the threads match. Then untighten the broken vacuum breaker (its best to replace both at the same time). Refit the new vacuum breakers and tighten. Turn the water back on and leave the tap on the get rid of the air. Once all air has been expelled. You can close the tap and pat yourself on the back cause you just changed a vacuum breaker.
Replacement of a circuit breaker is not as easy as you think. It protects a branch circuit in the house from current overload conditions. If you are not sure of what you are doing, refer the job to a licensed electrician to avoid an electrical accident.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

You should call a licenced electrician....but since you asked. You first need to make sure the breaker you are replacing is off. Unscrew the wire from the breaker and tape it for your safety. Pretty much all residencial breakers are stab-in type, so you just pull it out. Put your new one in, untape your wire and screw it back into the breaker

A vacuum breaker uses a vacuum to extinguish the arc when interrupting a circuit, while a SF6 gas circuit breaker uses sulfur hexafluoride gas. SF6 gas circuit breakers can handle higher voltages and currents compared to vacuum breakers. SF6 gas circuit breakers are also more environmentally harmful due to the greenhouse gas SF6, while vacuum breakers are considered more eco-friendly.
To reset a circuit breaker on a shop vac, first unplug the machine. Locate the circuit breaker on the power cord or the vacuum itself and press the reset button. If the breaker doesn't reset, check for any obstructions or issues with the vacuum that may be causing the problem.
Blowing the breaker every time you vacuum could be a sign of an overloaded circuit or a faulty breaker. Before changing the breaker, try using the vacuum on a different outlet to see if the issue persists. If the problem continues, it's best to consult a professional electrician to determine the underlying cause.
To replace a 15 amp breaker, first shut off the main power to the circuit box. Then, remove the cover of the circuit box and unscrew the old breaker. Disconnect the wires attached to the old breaker, connect them to the new 15 amp breaker, and securely screw it in place. Finally, turn the main power back on to restore electricity.
Replace it.
That would depend on the application as there are many uses and shapes and specifications for a vacuum breaker
Switch off incomong water, screw old device out, then new one in, switch on again
A vacuum breaker does not allow back flow into the potable water system A syphon breaker is normallly installed on a tank that there is a possibility of the tank imploding
"Air" and "Vacuum" describe how the breaker extinguishes the arcing current. An Air breaker opens far enough that the dielectric strenght of air is enough to extinguish the arc. A vacuum breaker's contacts are in a vacuum. Oil breakers use oil. SF6 breakers use SF6 gas to extinguish the arc.
A vacuum breaker is a device that prevents water in a toilet cistern or water tank, from syphoning back into the toilet cistern or water tank.
A vacuum breaker is usually installed at the top of a vertically-mounted drain pipe leading to a drain. The water drainage hose from an appliance such as a dishwasher or washing machine should never be plumbed directly into a drain stand pipe without a vacuum breaker. The vacuum breaker prevents contaminated water from the drain being sucked back into the appliance if it has a fault.
Yes.
A weak spring or broken valve seat. Just drain tank slightly and replace it,they are cheap and not worth fixing.
A vacuum circuit breaker is a high-voltage circuit breaker whose contacts separate within a vacuum dielectric. The vacuum contributes to extinguishing the resulting arc because ionisation cannot take place while the arc is stretched between the separating contacts.
