Around town I have seen a number of concrete markers with the letters MV on them. They usually come in pairs. Does anybody know what their purpose is?
They are meter valves. You usually see them located in someones yard in a subdivision. They are there to allow water metering for an entire subdivision. On the other hand, if they are in a person yard you do not like, you can go up to them and tell them it means Must Vacate.
OH! I ALWAYS wondered what they were. But sometimes I see them in the middle of nowhere, are those for future subdivisions? There is another one, BO - what does that one mean?
No they are not necessarily for future subdivisions. Just a valve for metering the water amount that flows through that area. BO are blow off valves.
What does blow off valve mean? And for the MV ones, if I go up to one will I find a readable meter near by or is it underground or something? I called surveyors to find out what these posts mean because it was driving me crazy and they told me they were markers for tree names. I knew that wasn't right b/c I never saw the trees they mentioned nearby. My husband thanks you - he doesn't have to hear, "What ARE those things" anymore. :allears:
Correct. It is so if they have a water main break, they can find the closest "main valve" to shut off the water. Also why they are in the middle of no where sometimes.
Which means....? Do we know what a blow off valve is? I wikipedia'ed it and see a definition for a combustion process. I'm assuming this one is related to water distribution somehow, right?
Where can I get one of those...there's a yard I'd like to send that message.....Oh! Nevermind8) :lol::lol::lol:
A blow off valve is just a valve that can be opened, when needed, to blow the water lines out or flush the lines..kinda like when you see a fire hydrant open and water gushing out of it...they are flushing the lines. If you are trying to hook up to a water line and there is no tap...and you need to install one, you can cut the water off at the MV, then open the BOV to flush the water and then tap to the waterline.
