PVC/CPVC – rigid plastic pipes similar to PVC drain pipes but with thicker walls to deal with municipal water pressure, introduced around 1970. PVC stands for polyvinyl chloride, and it has become a common replacement for metal piping. PVC should be used only for cold water, or for venting. CPVC can be used for hot and cold potable water supply. Connections are made with primers and solvent cements as required by code.[23]

Hawaii requires a licensed contractor for jobs exceeding $1,000.00 and/or requiring permits. Electrical and plumbing licenses are required for jobs involving those specific trades. General engineering contractors are needed for land leveling, sewers, excavations, and paving. General building contractors are needed for building structures such as additions and new construction.
The Federal Government does not regulate licensing for plumbers; they are on a state-by-state government level. Most states have some sort of licensing requirement for plumbers and any general contractors. However, if plumbers aren’t licensed, they could be subjected to expensive fines and it could result in the loss of their being allowed to practice their trade.

Your water heater is an essential part of your home, heating water for showers, dishwashing, laundry and more. On average, a traditional water heater will last 8-12 years. The general consensus is that it’s better to replace your water heater with a new one than to repair one that’s 10 years old or more. Older models are less energy-efficient and thus more costly to run than newer models with better technology. Here are some indicators of when it may be time to replace an old water heater instead of repairing it:

Many trades are looking at a critical time because more people are retiring than entering the fields. Plumbing is just one of those trades facing similar issues. Many women thinking about going into trade professions may stay away from plumbing based on some stereotypical thoughts like, say, plumbers buttcrack (yes, it’s a thing), and the fact that it can be an exceptionally messy job (such as clogged toilets). However, many women in the plumbing field feel that they are treated very professionally by both their male co-workers and their clients.

Specialized plumbing tools include pipe wrenches, flaring pliers, pipe vise, pipe bending machine, pipe cutter, dies, and joining tools such as soldering torches and crimp tools. New tools have been developed to help plumbers fix problems more efficiently. For example, plumbers use video cameras for inspections of hidden leaks or other problems; they also use hydro jets, and high pressure hydraulic pumps connected to steel cables for trench-less sewer line replacement.

Wall thickness does not affect pipe or tubing size.[21] 1/2" L copper has the same outer diameter as 1/2" K or M copper. The same applies to pipe schedules. As a result, a slight increase in pressure losses is realized due to a decrease in flowpath as wall thickness is increased. In other words, 1 foot of 1/2" L copper has slightly less volume than 1 foot of 1/2 M copper.[citation needed]
