You need heat to solder. Plumber's torches are small, handheld tools that allow plumbers to apply intense heat in precise areas, soldering and sealing new piping for installs and replacements. They're a must-have for any plumbing tools list.
PEX pipes. Cross-linked polyethylene (PEX) offers a unique benefit when used in commercial buildings. It is highly tolerant of heat and cold, and can, therefore, be used for different types of water supply applications.
PEX: Due to its flexibility and durability, PEX piping should last at least 50 years. PVC / CPVC: Under typical conditions, these pipes should last up to 100 years. Keep in mind that PVC pipes are often used for drainage because extreme heat can damage them.
PEX cannot be taken anywhere outside the house where it is directly exposed to UV for a long period. The synthetic material of the pipes can slowly disintegrate due to the light of the sun. Even light bulbs have been known to affect the lifespan of PEX water lines.
Pex pipe is made of a flexible material. They are easy to bend and install in tricky areas, like crawlspaces and corners. Most plumbers prefer to work with pex pipes for this reason.
The most common plumbing problems are clogged drains and toilets, leaky faucets and pipes, water heater issues, low water pressure, and a running toilet.
