Spring gardens need lots of water, so spring is the time that you may first discover a leak in your water supply line. Fixing a leak will first require locating where the leak is occurring. Slower leaks can be deceptive, because water can run along the length of a pipe or hose and drop off at the lowest point. When the source of the leak is found, you can begin the repair process.
Repairing a leak in your hose.
If your hose is leaking, repairing it will depend on the location of the leak. If it is occurring at a connection, look inside to see if the rubber washer is inside and intact.
If the washer is missing or worn, buy a pack of hose or assorted washers and replace it. If the hose leaks where the connection meets the hose, or at any point along the length of the hose, you will need to buy a hose repair kit. Check if the leak is closer to the male or female connection, because you will replace the closest connection to the leak. When purchasing a repair kit, you will buy either a male (threads outside) or female ( threads inside) replacement.
Simply cut the hose beyond the leak, and replace the connection by pushing the replacement connector (from the repair kit) into the end of the hose and tightening the provided clamp with a screwdriver.
Replacing your hose bib.
If your hose bib, the faucet outside your home, is leaking, it will force your hose to remain pressurized. Your hose may then burst, which may cause thousands of gallons to run into your yard if you are away from home when it occurs.
To replace the hose bib, you will need a pipe wrench or strong adjustable wrench, and a roll of pipe tape, which is a roll of thin plastic that is applied to pipe threads to prevent leaks.
After purchasing a replacement bib, turn off the water supply by locating the valve along the supply pipe that feds into the bib. If none is present, turn off the main supply valve, remove the hose from the bib, and open the valve on the outside bib until water no longer flows.
Turn the water bib counter-clockwise to remove it. It may be difficult to remove, especially if it has been in place for many years. When it is removed, apply pipe tape to the exposed threads by wrapping it in a clockwise motion. Screw the new bib on in the same direction, then tighten with the wrench.
Repairing a leak in your supply pipe.
Supply pipes that feed an outdoor hose bib are particularly susceptible to freezing in the winter. If a slow, dripping type of leak occurs, you can apply a pipe patch clamp. This consists of two rounded metal pieces that are bolted together around a piece of rubber gasket that is placed over a slow leak.
If you attempt to use a clamp, be sure to turn off the water and drain the pipe to keep water from leaking while you work. If water is leaking forcefully or in a steady stream, you may want to call a plumber like C B Lucas Heating & Air Conditioning to have the pipe replaced. Plumbers have the tools and expertise to perform more intricate jobs such as replacing supply lines.
