The answer to 'my pipe repair is leaking' is that there are several common causes for a leaking pipe repair, including improper installation, damaged seals or gaskets, and corrosion. Symptoms may include water dripping, pooling, or dampness around the repair site. To fix a leaking pipe repair, you'll first need to identify the source of the leak, then decide if it's a DIY fix or requires a professional plumber.
For minor leaks, you may be able to tighten fittings, replace washers or gaskets, or apply a sealant. However, if the leak is more severe, the pipe may need to be recut and reattached, or the entire section may need to be replaced. This type of repair is best left to a licensed plumber, as improper work can lead to further damage or leaks down the line.
