Well-made brass hose nozzles will last for years, but even the best of them can spring a leak now and then. Nearly always, leaks are due to a defective washer.

1. Step 1

   Disassemble the nozzle and pull out the nozzle insert. At the outer end you will see one or more rubber O-ring washers.

2. Step 2

   Remove the washer, using an awl, ice pick or screwdriver.

3. Step 3

   Slide a new washer onto the shaft.

4. Step 4

   If the leak is occurring at the hose connection, pull out the washer at the base of the nozzle and replace it.

5. Step 5

   A plastic nozzle may be damaged beyond repair. If that's the case--or if the leak is at the base of the nozzle but in the hose itself--buy and insert new end fittings following the steps in How to Mend a Leaky Hose.
