Water shut off valve? ?

Hi all- my mom needs to install a new dishwasher and the plumber said that the water needs to be shut off to the entire house to do so. He said the valve is most likely in the crawl space at the front of the house (which is unfortunately full of stuff). However, I am 98% sure this is the shut off valve which is beside our water softener in our laundry/utility room. Could someone please confirm before we spend money on a service call to install in case this is in fact not the correct valve? Thanks in advance!

    looks like the meter, which means that valve under it will shut everything down. Provided nothing has been changed and such.

    As far as the dishwasher goes, it can be tapped into the same line that the feeds the kitchen sink. Those have shutoffs, and they make Tee's to connect to those to feed dishwashers.  The current dishwasher could be hard piped, like mine was when we first moved in. That could be why he need to shut everything down, but you should ask about installing valves to isolate the unit, for future service needs.

    At worst there is a tiny plate somewhere in your front yard near the street. That will be the way to turn off city water supply to the house without having to access it, say in the event of condemnation or abandonment. If you don't want to or it is infeasible to move half your junk out of the way 5 times over just to find the knob, a city worker can be called to access this shut off valve.

    If that is your water meter, the valve is your main cutoff. If you don't have a separate cutoff just for the dishwasher, you should have one installed while the dishwasher is being installed.

    Yes, that tap before the meter is the shut off valve.  All water used by the house has to go through the meter to be measured.   At worst, you will have to dig under the pile of stuff to find a similar tap.

    Doesn't look like what's often used for the main shut-off, but it could be one. How could we know from here? You are there and able to look at what's where.

    You know how to find out if that's the main shut-off? Turn it off. If no water can then be got out of any faucet or the toilet in the rest of the house, then it's the main shut-off.

    if this is a valve next to the meter, then yes it's a main water shut off valve.

    Find your water meter. You can shut off all the water to the house by closing the valve at the water meter. You can shut off the valve you think is the valve, then walk around the house and open your sinks and bathtubs, etc. to prove the water is cut off.
