Galvanized steel potable water supply and distribution pipes are commonly found with nominal pipe sizes from 3⁄8 inch (9.5 mm) to 2 inches (51 mm). It is rarely used today for new construction residential plumbing. Steel pipe has National Pipe Thread (NPT) standard tapered male threads, which connect with female tapered threads on elbows, tees, couplers, valves, and other fittings. Galvanized steel (often known simply as "galv" or "iron" in the plumbing trade) is relatively expensive, and difficult to work with due to weight and requirement of a pipe threader. It remains in common use for repair of existing "galv" systems and to satisfy building code non-combustibility requirements typically found in hotels, apartment buildings and other commercial applications. It is also extremely durable and resistant to mechanical abuse. Black lacquered steel pipe is the most widely used pipe material for fire sprinklers and natural gas.
Hello I had a plumber do an estimate for me to replace our copper pipes with plastic as we have no existing walls up in our basement yet...pretty basic job... so we figured we could upgrade as we do live in Northern Ontario and it does tend to get quite cold here in the winters. We dont have any existing problems with our plumbing right now just figured it would be good time to do the job and perhaps change the pipes to 3 quarter inch for faster flow. Well I never thought in all my life I would get an estimate back that would state $350.00 an hour in labor...yes that is correct $350.00 an hour...estimated 10 hours for the job to be completed. So he quoted me $3500.00 for labor alone.. not supplies? Well needless to say I will be happy with my half inch copper pipes and will happily wait for my bathtub to fill up at a slower pace. Just wanted to know what your thoughts are on this $350.00 an hour quote? Thank you and enjoy your day.
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 problems, they use hydro jets, and high pressure hydraulic pumps connected to steel cables for trench-less sewer line replacement.
When a person has a blockage in their sewage system they often try to fix it themselves by adding an acid or a base such as Drano in an attempt to dissolve or dislodge the problem. These chemicals can get into the plumbers eyes when the sewage is splashed during the repair. The plumbers skin during the repair does come into contact with the sewage water. The owner of the toilet might not report to the plumber they have already tried Drano a highly caustic base .
