Adjust the hydrant seals. Worn linkages can cause a leak by not properly forcing the rubber shut off assembly into the valve seat. If the handle is nearly all the way down before you feel resistance caused by the plunger hitting the valve seat this may be the problem. Simply adjusting the mechanism at the top of the valve stem to extend it slightly might solve the problem. Make the adjustments in small increments to avoid damaging the valve assembly.
Repair the hydrant. Often the cause of a leaking hydrant is worn or damaged gaskets or seals in the valve assembly. These components can often be replaced without digging up the valve assembly.
Find a supplier for your brand of hydrant. Most hardware stores will have supplies as will well drillers in your area. Unless you can leave the hydrant dissembled for several days you will want to get replacement parts before starting work.
Unscrew the head assembly from the riser pipe. This might be difficult since it has likely been outside for many years and may be rusted tight. Liberal use of penetrating oil, hammer tapping, and long handles on the pipe wrenches can all help.
Pull up the connector rod. The seals and valve mechanism should come with it.
Inspect and replace those components that seem worn or deteriorated.
Reinsert the valve assembly and thread the head assembly onto the riser pipe. Be sure to use pipe dope on the threads and seals to aid in sealing.
Adjust the plunger seating pressure as noted above.

How to Add IntegersIn Feburary 2016 27,

Understand that when numbers have no signs in front of them, they are positive. For example, if you have the problem 3 + 5 = ?, both 3 and 5 are positive. You simply add the numbers together using elementary math. For example, find 3 on a number line and count five places to the right to solve the problem: 3 + 5 = 8. Adding two positive numbers always produces a positive result.
Ignore the signs of the numbers initially when adding two negative numbers. Follow the same procedure for adding positive numbers. For example, for -3 + -5 = ?, make the problem 3 + 5 = ? and solve it. The result will be 8. Once you have a solution, add a negative sign in front of the number. So 8 becomes -8.Think about it this way: Say a friend borrowed $3 from you last week, then borrowed $5 from you today. Your friend now owes you $8.
Examine problems that have one positive number and one negative number. If the positive number is larger, subtract the numbers, and then put the positive sign in front of the answer. For example, suppose the problem were 8 + -3 = ?. You would convert the problem to 8 - 3 = ? The result would be 5. You can also use a number line, start at 8 and go three places to the left to find that 5 is the result.
Subtract the numbers and put a negative sign in front of the result if the negative number is larger. For example, consider -5 + 3 = ? You would subtract 3 from 5 to get 2, then add a negative sign for your result: -2.
