Public works and private contractors faced a tough repair job when a water main broke in Ontario. Simcoe Reformer reported that it took almost 24 hours to repair the break while the traffic was rerouted for the repair duration. The urgency of the repair meant the workers continue overnight even as temperatures dropped as low as 25 degrees below zero.

Aside from the above, why is it better to entrust your plumbing work to the experts? Here are a few factors to think about:
Equipment and Methods
Professional plumbers simply have a more complete set of equipment for plumbing work, items that the average household aren’t likely to usually have. They are also updated with the latest procedures for dealing with different plumbing problems, ensuring that their solutions are good for the long term. For this reason, even individuals who have some plumbing experience may also hire professionals for repairs.
Expertise and Experience
For the usual homeowner, where do they get what they know about plumbing? Some are from their neighbors or maybe from some website. Not to say that all those information are false, but neither are they completely accurate all the time. They can’t match the knowledge of professional plumbers with years of training and experience in this specific field.
Wide Range of Services
Professional plumbing companies, like Harris Plumbing Inc., offer multitude of services such as drain repair, pipe repair, backflow prevention, tree root removal, video camera inspection, hydro-scrub, and more. This means that whatever the problem in your home’s plumbing, be it big or small, they can take care of it.
