Yes, pipe leak tape can fix a leak. The adhesive is strong and can hold for years. While silicone tape is a temporary solution to a leak, pipe leak tape can be used long-term. Although it is still advisable to call a professional plumber to provide a more permanent solution to your pipe leak.
Sometimes called “Teflon” or “Plumber's” tape, pipe threat tape is often used to fix leaking pipe joints. The other type of tape you may have seen is called “self-amalgamating,” “self-fusing,” or “leak repair” tape. It's used to fix hairline cracks or other non-joint pipe leaks.
Duct tape and electrical tape can be used. Take care to cover the entire leak. Also, make sure the tape makes good contact with the pipe so no pockets form where water can gather. This might cause the tape to lose grip.
Use epoxy putty or pipe putty as a temporary fix to a leaky pipe. Pipe putty is designed to harden at room temperature and seal the hole or crack. Turn off the water supply line in the house.
Repair of holes in pipes and pipelines, for temporary plugging of small water leaks: waterproof duct tape is the perfect ally in your garden and your kitchen. The tape does not fear water and can be used to seal small leaks and holes in ducts, pipes, watering cans, etc.
An important thing to remember is that PTFE tape should not be used when connecting PVC fittings or valves with a female (FPT) thread. If the tape is used on female connections, a wedging action can occur which will cause major stress on the joint during assembly. PTFE tape does not guarantee a leak free connection.
Pipe wrapping tape has many practical uses in plumbing, the oil and gas industry, and at production facilities. It is most commonly used to create a water-tight seal on pipes.
Wrap pipes with heat tape or thermostatically controlled heat cables. Be sure to follow all manufacturers' installation and operation instructions. Seal leaks that allow cold air inside, near where pipes are located (i.e. around electrical wiring, dryer vents, other pipes), with caulk or insulation.
Plumber's tape, often called Teflon tape, (polytetrafluoroethylene, or PTFE) helps you get a watertight seal on threaded pipe joints.
100% Waterproof
**Not recommended for leaks in water systems under pressure.
Pipe dope is generally stronger seal than Teflon tape, which is why plumbers and other professionals use it rather than tape for seals that are permanent.

nothing lasts forever but as long as you do not disturb it it should last indefinitely .
Insulate your exposed pipes by wrapping them with foam, rubber or fiberglass sleeves. You can also use rags or newspaper. Be sure to wrap the pipes with at least an inch of those materials, then cover them with plastic wrap or aluminum foil to keep them dry.
We all know that freezing begins at 32° F or 0° C, but at what point do pipes freeze within our own homes? Temperatures only need to drop to about 20° F for a few hours to put exposed pipes at risk. So, your best bet is to insulate your exposed pipes to keep that temperature well above the freezing point.
“By wrapping the pipes in plastic and coating the fittings and fasteners, corrosion is less likely to occur because it has virtually no exposed metal to conduct with.”
Pipe Dope. Pipe dope, also referred to as pipe joint sealant/compound, is a form of liquid used in sealing threads just like tape. The container comes with a cap that has a swab brush attached to it. The brush is used for applying pipe dope on pipe threads before attaching the fitting.
Pipe insulation materials, such as fiberglass, are best for pipes exposed to hot temperatures, while foam and rubber are a better fit for cold water pipe lines but work in hot pipes as well.
