The ink would have barely dried on your Deed before you find out there is a plumbing nightmare brewing in the home of your dreams. Buying a new home is fraught with a dozen or more concerns, but they should be paint colors and swatches, not bubbling sewage and rotting main lines. Do not assume your inspector will catch everything. Plumbing is a great deceiver when someone is not an expert in the minutia.
The right tools in the right hands. That’s the way to get most jobs done properly. You wouldn’t pick up a scalpel and walk into an operating theatre without the proper education and training, and you shouldn’t just pick up a toolbox and go into a plumbing job unprepared, either. Tools are only going to get you so far, after all. Without the extensive background knowledge that true professionals possess, those tools are only going to get you into further trouble.
