Which type of valve is commonly used on private water supply systems and the words open or shut appear in a window as the valve approaches one position or the other?

Post indicator valves

Explanation:

Post indicator valves were first made and patented by its inventors Crookham and Lee in 1972 for Clow Corp., a pipe manufacturing company. In 1974, they were publicly installed for the first time.

PIV, indicator post, I post, IP, post indicator, or wall post, a post indicator valve is a valve assembly used for the purpose of underground piping for water supply to fire protection systems such as sprinklers, sprays, foams, deluges, etc. They have a lockable actuator which looks like a red metal steering wheel or a wrench/handle on top of a post. It consists of a glass or plastic window, which indicates whether the valve is open or shut.

PIVs can be of 3 types:

Ground Post: This is an indicator post that has its base buried in the ground and typically has a lockable handle or clamp. It is used when the valve is installed out of the building.

Wall Post: This is a short indicator post, usually horizontally bound through a flange to the wall of the building. This post can be operated by a handwheel.

Wall Post: This is a short indicator post, usually bolted horizontally to the wall of the building through a flange. This post is operated through a handwheel. This is used when the water supply passes through a cavity of the wall.

Pedestal Post: This post looks like a ground sign. Furthermore, instead of being embedded in the earth, it is bolted through a flange to a horizontal surface, usually a concrete base. It also operates through a handle or wrench that can be locked. It is helpful when the valve is situated inside a building and the water supply is stored

elly's long hair:

a. if the salon only takes cash, then this isn't the problem. it doesn't matter how much she has in her checking account.   she can't get a haircut until she has the cash.

b. if she has overdraft protection, then there's no problem.   she can go ahead and write a check that her account can't cover, then sometime later, pay the bank some outrageous usury for loaning her a few bucks for a few days, but with beautiful hair.

c. if elly has some principles, and doesn't want to write a bad check, then now she has a problem.   her desire for the new hairstyle is in conflict with her honesty and integrity.

d.   if the bank will not process a check she writes, then even if she had a million $$ in her account, she couldn't use any of it.   the amount she has in her account is not the problem.   and if i may suggest, she might as well close her checking account, and put the money where it'll work for her.   it's not doing her a bit of good in a checking account, since she can't write any checks.

justin can't pay the full balance:

a. he can't even handle the credit limit he has now.   under no circumstances should he ask for a higher limit.

b.   he can ask for the grace period to be extended.   but that's no solution, the bank will almost certainly refuse anyway, and there are much better options.   he knew the rules of his credit card when he started using it.

c.   he definitely should pay the interest on the balance, plus as much of the balance as he can cover at the same time.

d.   he definitely should pay the minimum otherwise they could shut down his card.   he should also pay as much more as he possibly can.   he should also remember the awkward situation he's in, stop buying stuff on credit that he can't afford, and avoid adding any more debt.

i'd say that justin's best best option isn't on this list of choices.   what he has to do:   pay as much as he can at least the minimum payment plus as much more as he can and then avoid adding more debt.
