Answer from Michigan:

Water services are a minimum 5 feet deep here. This is in southeastern Michigan, it is deeper as you go further north. We can easily reach zero degrees here and sometimes it goes to ten or 15 below zero. I do not know how deep the services are in the Upper Peninsula where it gets really cold.

The valve at the bottom of the "box" is a bladed cock that is will turn 360 degrees but only needs turning 90 degrees for either off or on. It has a"box" over it to guide the key and protect from dirt and debris. Sometimes the box needs to be blown out with high pressure air in order to reach the stop with the key. The municipality usually does this at no charge.

Depending upon the municipality, the valve may not have an extension and needs to be reached with a street key that is over six feet long, or has an extension to within 2 feet of the surface or possibly 4 feet of the surface.

I will try to find the name of the supplier of these items so that you can see how it is done in the North.

Look here:


see pages GA-3 thru 7 for pictures.

If you are thinking of purchasing something like this, do not get it with the rod installed. They have tendency to seize up, or rot/rust out over the years or the cotter pin deteriorates. Either of these occurrences require digging it up and doing the repair.

If you want to see a typical curb stop, look up Z22-444-M-NL in their catalog.
Plumbus, Tango and MASTRPLUMB like this.
