Garbage disposal installations and repairs should always be done by a professional plumber.
Homeowners, naturally, want to save money and like projects that they can do themselves.
But, when it comes to garbage disposals, it sometimes costs more to fix or install one yourself than paying a professional to do it the right way.
Garbage disposals require special piping, drains and fittings. Garbage disposals will also need to be hooked up to electrical power which is just another reason why a professional should be hired for the job.
A professional has the training and experience. It will take no time to install a unit, add the drain, piping and have the unit running properly.
Repairing a garbage disposal is another job for a professional. They can troubleshoot a problem and have it fixed in very little time. In some cases, you might just need a new disposal.
If you do want to attempt a repair on your disposal, you must always remember to turn off the breaker that controls the power to the unit. Many people try to fix a unit without doing this and end up blowing the circuit breaker or frying the unit.
