In this episode:
Master electrician Heath Eastman brings us to the Tool Lab to explain everything we’ve ever wondered about power tool batteries. With a brief history of the evolution of power tool batteries, Heath shows us what they look like inside and explains how manufacturers calculate battery voltage.
And voltage isn’t everything. Heath teaches us what amp-hours mean and how they affect how power tools run. To demonstrate, Heath gives us a first-hand look at the difference between what two 18-volt batteries can do based on their amp-hour rating.
Next, we join mason Mark McCullough as he helps a homeowner solve a burning problem: replacing a fireplace cover. With the homeowners’ enjoying a wood-burning fire every now and then, they’re concerned about their old fireplace doors and stubborn flue, and Mark knows just what to do.
After inspecting the fireplace and removing the old fireplace doors, Mark and the homeowner set out to replace them with a new set of doors. The two install insulation and the holding clips before installing the doors in the opening. Finally, Mark makes a simple repair that will keep the flue working for years to come.
Finally, we join plumbing and heating expert Richard Trethewey as he teaches host Kevin O’Connor everything he needs to know about plumbing clogs. From toilets and sinks to showers and drain lines, Richard shows Kevin what each system looks like inside and where clogs most often occur.
With each fixture and fitting, Richard shows Kevin the best tools and methods for clearing clogs. He explains some of the most common issues with clearing clogs and how to prevent them. Richard even breaks out some newer tools for pressuring systems and clearing stubborn clogs.
Tool Lab: Understanding Battery Voltages
Master electrician Heath Eastman brings us to the Tool Lab to explain everything we’ve ever wondered about power tool batteries. With a brief history of the evolution of power tool batteries, Heath shows us what they look like inside and explains how manufacturers calculate battery voltage.
Where to find it?
Heath breaks down the basic voltages of cordless tools and explains the technical aspects of battery technology. He takes a battery apart to show the individual cells and circuit board that make up the battery packs. Then Heath explains the difference between 10.8V and 12V and 18V and 20V ratings. Finally, Heath talks about Amp Hour ratings how they relate to voltage ratings—before giving homeowners some guidance on what level voltage tool they will most likely need (and not need).

How to Unclog Any Drain
Plumbing and heating expert Richard Trethewey teaches host Kevin O’Connor everything he needs to know about plumbing clogs. From toilets and sinks to showers and drain lines, Richard shows Kevin what each system looks like inside and where clogs most often occur.
Where to find it?
Richard demonstrates how to handle simple clogs in a bathroom sink, kitchen sink, and toilet using different mechanical devices and the proper techniques. When using a plunger, he recommends creating a seal with the flange and pulling back on the plunger, allowing the clog to break up. A closet auger is used for toilet clogs and has a protective sleeve to ensure that the porcelain toilet isn’t damaged. K-3 Toilet Auger manufactured by Ridgid.
The water pressure produced by a drain bladder can scour away the material left in place by a drain snake, in this case, one made by Cobra Tools.
