A friend of mine has replumbed his own house using plastic pipe and push fit connections, he is not a plumber by trade but he says with all the modern plastic fittings available to-day domestic plumbing is easy, he says there is no need to use a blow torch or solder.
He decided to have a go himself after getting outrageous quotes from local tradesmen, he got most of his information on plumbing from a diy book from the local library, if it is that easy why do plumbers charge so much.
I blame the low lives, non skilled who call themselves "plumbers" but have less skill then a handyman with a kindergarten education.
What I have been saying for over 25 years SCREW PLASTIC and push on connectors as most inept contractors that go with plastic say "its fast" nothing about quality
I am called a dinosaur as I still braze / solder my copper joints and still use strictly cast iron for drainage and vent and my roof drains are caulked using lead and oakum and 3 ft x 3ft x 4 PSF (pounds per square foot) sheet lead.
How can a person call themselves a "professional" or craftsman knowing that anyone can glue a piece of pipe together or push two pieces of copper /plastic into a fitting?
Tradesmen wanted fast and they wanted easy they got exactly what they wanted. A non skilled application that goes in fast cheap and requires no skill to install.
The problem with our societies, England / USA is the new wave of non skilled labor (labour) willing to work really cheap but because the skill level is lacking many unscrupulous contractors took the easy way out and used materials a child who is 5 or 6 years old can install so training is not even an issue any more
Once someone sees how easy "plumbing" is then why hire someone when anyone can do it unless the contractors decide to work cheaper then the next bloke next to him so the price wars begin who can work the most hours for the less amount of money.
Regarding your so called "outrageous" Quotes Thank GOD YOUR THERE and I AM HERE as I pride myself as being one of the most expensive Master plumbers in my area.
I firmly believe with my education someone has to compensate me for my professional skill level and my on going training.

My education cost me dearly and I will not lower my standards just to be in a rat race who can get in and get out the fastest and move on to the next victim.
The trades wanted fast and easy and they got it .
6 week plumbers no training except monkey see monkey do and no skills what so ever BUT it sure helps some employers keep the cost of doing business really low as they no longer have a need for skilled craftmen
