No, you do not need a plumber to change a bathroom fixture. If you are not experienced with repair, it would be in your best interest to hire a plumber. If you are experienced, however, there are many sites online that will instruct you on how to change the fixture.
No
Use a drain cleaner such a Liquid Plumber first. If that doesn't resolve the issue you may need to rent a pipe-snake to break up the clog. You could also call a plumber, however renting a pipe-snake is generally cheaper than a plumber.
Ballasts can be quite different even if you order a replacement part for a specific fixture. You need to follow the wiring diagram on the new ballast. If this is confusing or not easy to follow, you need a competent electrician to do this for you.
Look at the wattage capacity of the fixture. Some fixtures are limited to 65 watts, some can take much more. If you use a larger bulb than what the fixture was designed for you create a fire risk. If you need to use a larger bulb but the fixture is limited to 65 watts, you need to change the fixture.
We have a leaky drain and I need to hire a plumber. How would I go about finding a qualified plumber?
Not at all. Home handymen can attempt this simple repair themselves.
It can be dangerous my dad does it but you need to turn the power off.
You need to be good at math, science. And you have to go to Plumber School. I think there's one in France.
depending on the kind of plumber but still not much
There is no requirement to have any college to become a plumber.
You know you need a plumber if you repair whats broken or whats wrong with the sink yourself.The plumber should be certified and come from a reputatable company. you should also ask for references from the plumber if your not sure that they can do the job.
dunnooo:)
