Step 1 - Replace the O-rings
Purchase rubber O-ring washer for water hose connectors. Use a small knife or flat head screwdriver to gently remove the old O-ring from the hose connector and discard it. Use silicon grease or petroleum jelly to lubricate the O-ring and install it in the connector. This will usually fix most leaks for hose reel connectors leading to your garden hose.
Step 2 - Replace the Leaky Connector
If replacing the O-ring in the hose reel connector does not stop the leak, the connector itself may be damaged beyond repair and need to be replaced. Purchase a "male" or "female" (depending on the type you need) water hose connector that matches the size of the connector on your hose reel.
Slice the hose immediately below the old connector and install the new water hose connector according to the manufacturer's instructions. In some cases, you may need to buy a quick connect coupler to replace the faulty hose reel connector. Avoid water hose connectors that are installed by simply tightening down two screws as these types of connectors will usually leak badly after a short period of time.
