Different problems compound the already established plumbing issues that a residential or commercial property may face. The most common and destructive of these are leaks, which can go undetected for long periods of time, resulting in mold growth, excess moisture, and other conditions that compromise the integrity and safety of a structure. The average person cannot be expected to know all the signs of a plumbing problem, but there are several that one can easily recognize and that merit a call to the professionals. These include drips or puddles of water that seem to come out of nowhere, mysterious wet spots on walls, ceilings, or floors, and pronounced bulging or sagging in the form of hoses, pipes, or the structures that contain them.
The common problems facing the plumbing profession today are addressed using a variety of methods and tools that are designed, quite simply, to work well and to work fast. For aging infrastructure, replacement or repair is often the best solution, and professionals today use modern, durable materials to extend the life of the fixtures. In cases of mineral buildup, experts employ water softeners and chemical cleaners that dissolve the deposits without harming the plumbing. Where improper usage leads to obstructions, plumbers use specialized equipment like drain snakes and hydro-jetting devices to clear the way. In periods of extreme cold, professionals can insulate pipes or put heating cables in place to prevent freezing. But when they engage in all these targeted strategies to ensure a robust and reliable plumbing system, they seldom do so with a pay-by-the-hour mentality.
Homeowners and business managers must engage skilled professionals to fix plumbing problems. They cannot hope to do it themselves with any mix of methods that might best be termed 'improvise,' 'adapt,' and 'overcome.' Sure, there are Army strongpoints so well known that new recruits can find them without being led blindfolded and without maps. But even so, the new soldiers would have had to learn some diagnostician tricks and use some high-tech tools and low-tech better-mate ergonomics to accomplish these feats of plumbing handiwork without going hither and yon across the military theater of the absurd.
In short, there are several good reasons to hire a plumber.
