The difference between pipes and tubes is simply in the way it is sized. PVC pipe for plumbing applications and galvanized steel pipe for instance, are measured in IPS (iron pipe size). Copper tube, CPVC, PeX and other tubing is measured nominally, which is basically an average diameter. These sizing schemes allow for universal adaptation of transitional fittings. For instance, 1/2" PeX tubing is the same size as 1/2" copper tubing. 1/2" PVC on the other hand is not the same size as 1/2" tubing, and therefore requires either a threaded male or female adapter to connect them. When used in agricultural irrigation, the singular form "pipe" is often used as a plural.[20]
Cast iron and ductile iron pipe was long a lower-cost alternative to copper, before the advent of durable plastic materials but special non-conductive fittings must be used where transitions are to be made to other metallic pipes, except for terminal fittings, in order to avoid corrosion owing to electrochemical reactions between dissimilar metals (see galvanic cell).[18]

Most states and localities require plumbers to be licensed. Although licensing requirements vary, most states and localities require workers to have 2 to 5 years of experience and to pass an exam that shows their knowledge of the trade and of local plumbing codes before they are permitted to work independently. In addition, most employers require plumbers to have a driver’s license.
Going to school can be expensive. But, don’t let the cost keep you from pursuing your plumbing education. There are plenty of available monies to be found for most trades, plumbing being no exception. The first thing you MUST do when applying for financial aid is to fill out the FAFSA. The FAFSA is the most important step to take when you’re looking for scholarship and grant money. Once that is filled out, you will be eligible for other financial aid opportunities, alongside whatever the Pell Grant allows you.
Plastic pipe is in wide use for domestic water supply and drain-waste-vent (DWV) pipe. Principal types include: Polyvinyl chloride (PVC) was produced experimentally in the 19th century but did not become practical to manufacture until 1926, when Waldo Semon of BF Goodrich Co. developed a method to plasticize PVC, making it easier to process. PVC pipe began to be manufactured in the 1940s and was in wide use for Drain-Waste-Vent piping during the reconstruction of Germany and Japan following WWII. In the 1950s, plastics manufacturers in Western Europe and Japan began producing acrylonitrile butadiene styrene (ABS) pipe. The method for producing cross-linked polyethylene (PEX) was also developed in the 1950s. Plastic supply pipes have become increasingly common, with a variety of materials and fittings employed.

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.
The word "plumber" dates from the Roman Empire.[3] The Latin for lead is plumbum. Roman roofs used lead in conduits and drain pipes[4] and some were also covered with lead, lead was also used for piping and for making baths.[5] In medieval times anyone who worked with lead was referred to as a plumber as can be seen from an extract of workmen fixing a roof in Westminster Palace and were referred to as plumbers "To Gilbert de Westminster, plumber, working about the roof of the pantry of the little hall, covering it with lead, and about various defects in the roof of the little hall".[6] Thus a person with expertise in working with lead was first known as a Plumbarius which was later shortened to plumber.

Each Government at the state level has their own Authority and regulations in place for licensing plumbers. They are also responsible for the interpretation, administration and enforcement of the regulations outlined in the NCC.[39] These Authorities are usually established for the sole purpose of regulating plumbing activities in their respective states/territories. However, several state level regulation acts are quite outdated, with some still operating on local policies introduced more than a decade ago. This has led to an increase in plumbing regulatory issues not covered under current policy, and as such, many policies are currently being updated to cover these more modern issues. The updates include changed to the minimum experience and training requirements for licensing, additional work standards for new and more specific kinds of plumbing, as well as adopting the Plumbing Code of Australia into state regulations in an effort to standardise plumbing regulations across the country.[40]

Hello, I too have a Lennox pellet stove, the Eilite mase in 2008. Ours hasn't been professionally cleaned ever. And now it has built up with dust and in the different compartments in the two side panels such as the blowes, motors, and switches. Now when we run it, it will start up and run fine for about 20 minutes and then shuts down. Today I got it to run for 3 hours and then it stopped feeding pellets. I've cleaned out the hooper with a shop vac, vaccummed thoroughly inside the stove, and wiped the visible and reachable dust, but it still isn't working properly. Did you find out any information about your stove. I'm having trouble finding DIY videos for this brand.

Plumbing fixtures are exchangeable devices that use water, and can be connected to a building's plumbing system. They are considered to be "fixtures", in that they are semi-permanent parts of buildings, not usually owned or maintained separately. Plumbing fixtures are seen by and designed for the end-users. Some examples of fixtures include water closets[33] (also known as toilets), urinals, bidets, showers, bathtubs, utility and kitchen sinks, drinking fountains, ice makers, humidifiers, air washers, fountains, and eye wash stations.

There’s often an Allen wrench that comes with the garbage disposal. I keep it under the sink. When the thing jams, follow the directions in the manual, and I won’t need to come out. Another plumbing tip, don’t believe the myth about putting lemon peels in the disposal to make it smell better. That will just make it jam faster.  These are the things you should never pour down the drain.

The water/liquid is stored in a boiler and pushed into a plumbing manifold so that it can be properly circulated throughout your home floors as designed.

For many centuries, lead was the favoured material for water pipes, because its malleability made it practical to work into the desired shape. (Such use was so common that the word "plumbing" derives from plumbum, the Latin word for lead.) This was a source of lead-related health problems in the years before the health hazards of ingesting lead were fully understood; among these were stillbirths and high rates of infant mortality. Lead water pipes were still widely used in the early 20th century, and remain in many households. In addition, lead-tin alloy solder was commonly used to join copper pipes, but modern practice uses tin-antimony alloy solder instead, in order to eliminate lead hazards.[13]
I have no problem paying for any service I receive but when Allied Reddi-Rooter came into my home and immediately tell me and them tell me it would cost me 350.00 for them to install a new Rheem water heater (his recommendation) that cost 409.00 I have a problem. If the cost is exactly how Home Advisor indicates then he’s charging 350.00an hour.  I did my homework checked with other plumbers and it. Would not take an hour to remove old and install the new water heater. Thank Goodness I did my research won’t be using their services and I will be letting others know what happen to me. Shame on you Allied

The best way to find a good plumber is to ask friends and neighbors, remodeling contractors, and real estate agents. Nothing holds up a home sale faster than plumbing problems, so realtors often have a list of reliable, fast-response plumbers. Once you find a plumber you're satisfied with, keep his numbers (office, home, and cell phones, and beeper) handy for emergencies. This Old House: Dripping faucets, running toilets
Had some scheduling issues recently, which is why 4 stars. Strongly suggest that they get rid of the policy (of which I was not aware) that if you are unable to answer your phone for the "courtesy call" that the plumber is on the way, your appointment gets cancelled. Along with the 4 hour window, this is not customer-friendly. But other than that, I've always been very happy with the actual work done and the overall efficiency of the company

As with other construction workers, employment of plumbers, pipefitters, and steamfitters is sensitive to fluctuations in the economy. On the one hand, workers may experience periods of unemployment when the overall level of construction falls. On the other hand, shortages of workers may occur in some areas during peak periods of building activity.
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.

Be prepared for a more urgent situation by establishing a relationship with a plumber before you actually need him. If possible, hire him to do nonemergency repairs or fixture installations during normal hours. It's easier to get a plumber's attention if you're a regular customer and not a panicked stranger calling at 8 p.m. on a Saturday night asking him to fix a gushing waste pipe in your basement.

I had another lady who said she wanted to run to the grocery store to get some coffee to make for me and my guys while we were installing her new kitchen. She said she was just gonna run to the store and asked if we wouldn’t mind keeping an eye out for her one-year-old daughter who was sleeping at the time. We said fine, but she ended up not returning until four hours later. The kid was screaming her head off and we didn’t know what to do. We tried holding her. We didn’t know if she was hungry or what to feed her. She just kept crying.

Then again, if you don’t have the time, tools, or inclination to do your own plumbing repairs, you can hire a pro. A plumber can handle nearly any problem that involves pipes, from replacing a garbage disposal to unclogging a bathtub drain, but, if your problem is a stopped-up drain, you’re usually better off calling a drain-clearing service because these are generally less expensive.
Our plumbers use high-quality equipment and the best tools or every job. We practice according to the highest industry standards, so you can depend on safe and effective repairs that last.

After completing an apprenticeship program, plumbers, pipefitters, and steamfitters are considered to be journey workers, qualifying them to perform duties on their own. Plumbers with several years of plumbing experience may earn master status by passing an exam. Some states require a business to employ a master plumber in order to obtain a plumbing contractor’s license.

Quoted Prices Stay the Same We know how frustrating it is to be told one price before the job, but see a completely different (higher!) number on your invoice. When you work with us, you can rest assured that price will not change. We do not change the price based on how long the job takes. What we quote at the beginning is what you can expect once the work is complete.
Sid called ahead and let me know what time he would show up. He arrived on time and quickly determined what needed to be fixed and explained it. He needed to make a few trips out to his truck to grab tools/supplies and put shoe covers on each time he entered the house. He quickly fixed our issue and cleaned up when he was finished. Great service from Sid! Just had another visit to fix a leaking meter horn. Andrew called 20 minutes before he arrived and quickly decided what needed repair. He didn't have the exact part needed on his truck, but he was able to get it from the warehouse quickly. He fixed our issue and cleaned up the area well. Thanks to Andrew and Ben Franklin Plumbing for fixing our plumbing problem on Christmas Eve!

Tankless water heaters usually cost more to install than traditional tanks, because many homes need to be retrofitted to accommodate the new system. Tankless electric water heaters retail on average between $150 and $1,200, and tankless natural gas water heaters retail between $200 and $1,300 on average. The lower prices ($150-$250) are generally for point-of-use tankless heaters that can be installed to boost hot water in high-demand areas such as the bathroom or kitchen sink. Tankless water heaters designed to heat whole homes usually start under $300 at the low end and go up to $1,400 or more. Pricing for whole-home varies with the heater’s technology and features. Nationally, standard water heater installation costs average $360-$780, but tankless water heater installation costs may range from $400 to $1,000, depending on the work needed. Some perks of tankless water heaters are that they have nearly double the life expectancy of traditional water heaters and are generally more cost-efficient. Homeowners may be able to save $100 or more per year on their utility bills with an Energy Star approved tankless heater, depending on how much hot water they use.

"I needed to hire a painter for my place of business which is a hair salon. I hired Jose and he was just fantastic! His communication was very thorough and he was on time and he did a wonderful job. I actually needed him to repaint the room from a prior painter who did a very sloppy job. Jose made my room look bright and beautiful and on top of it he cleaned everything so thoroughly. He wanted to leave my room spotless and I could tell he took a lot of pride in his services. I was very impressed with his work and I have already hired him to do a plumbing job next in my salon. He is the nicest guy you want to work with and he has an excellent work ethic. He is very upfront and honest he will tell you what he can or cannot do and his prices are very fair. Jose is going to be my go to guy for any handyman work I need in my salon going forward. I highly recommend him for whatever your handyman needs maybe. This man is a true professional!"

Wooden pipes were used in London and elsewhere during the 16th and 17th centuries. The pipes were hollowed-out logs, which were tapered at the end with a small hole in which the water would pass through.[16] The multiple pipes were then sealed together with hot animal fat. They were often used in Philadelphia,[17] Boston, and Montreal in the 1800s, and built-up wooden tubes were widely used in the USA during the 20th century. These pipes, used in place of corrugated iron or reinforced concrete pipes, were made of sections cut from short lengths of wood. Locking of adjacent rings with hardwood dowel pins produced a flexible structure. About 100,000 feet of these wooden pipes were installed during WW2 in drainage culverts, storm sewers and conduits, under highways and at army camps, naval stations, airfields and ordnance plants.
