Repair of small pipe leaks
First steps
Observe which area of the pipe is leaking, and then temporarily shut off the water supply to that area. The shut-off valve for a particular plumbing installation is located near the main pipe and has an external tap that simply needs to be turned counterclockwise.
Cleaning
Once the water supply is shut off, take a piece of cloth and wipe the pipe to be repaired dry. Clean the pipe so that there is no mold that could clog it later. To do this, take some sandpaper and use it to rub the pipe surface at the leaking area. This will make the pipe clean and dry, making it easier for you to make the repair.
Apply adhesive tape
Once the surface is cleaned, take sealing plumber's tape and place it on the location of the leak. Wrap the tape until several layers are wrapped around the pipe. Be sure to wrap the tape tightly around the area of the leak. The wrap should protrude a few inches on all sides of the pipe.
Caulk
Buy some epoxy paste at your nearest hardware store and apply it to the area where the water is leaking. Make sure to apply the epoxy to the pipe only after it is completely dry. This sealant is almost like modeling clay and must first be flattened on the palm of your hand and then adhered to the pipe surface. Allow the epoxy to cure for 20 to 25 minutes and then turn on the water supply. Your leak will then be cured.
Retightening the joints
Another reason for small pipe leaks is that the threaded connections that exist between the various parts of the pipes become loose. To fix this problem, locate the joints of the pipes and use a small wrench to tighten the bolts that secure the threaded joints. Be careful not to apply too much force, as this could cause the pipes to crack completely. Before tightening, it is recommended to clean and dry the connections with a cloth and apply some epoxy resin as described in the step above.
Using a hose
To fix a small pipe leak, another idea is to completely cover the area where there is a slit or hole with a section of your garden hose pipe. To do this, use a sharp knife to cut a piece of the old hose lengthwise. Wrap this piece around the spot on the pipe where there is a leak. Now, on the underside of the pipe, attach the clamp designed for the hose by placing it on the wrapped piece of hose. The clamp must be screwed to the place where there are prepared screw holes. As an additional precaution, you can also wrap this part with plumber's tape.
