In this episode:
Plumbing and heating expert Richard Trethewey takes us on a road trip to solve a homeowner’s shower problem. Every time the homeowner turns on their tub spout, water also flows out of the showerhead. After inspecting the issue, Richard finds a problem with the water pressure and provides the homeowner with a simple—and free—fix.
Next, we head to the shop where master electrician Heath Eastman gives host Kevin O’Connor a lesson on wire sizes. Heath displays different wire sizes, ranging from thin to thick. He explains how each wire type gets its name and gives Kevin some examples of what each wire might be used for.
Finally, we follow Mason Mark McCullough on a house call to help a homeowner fix their flagstone entryway. With a few broken joints, several of the stones in the entryway are starting to come loose, so Mark chips out of the old joints and lays the stone back in new mortar beds before showing the homeowner how to blend the repair in with a sponge. Then, Mark finishes the job by installing a soft joint, which is essentially caulking between the stone and a wood stair riser for a perfect fit.
How To Troubleshoot a Leaky Showerhead
Richard troubleshoots how to repair a homeowner’s water pressure valve for their tub and shower.
Understanding Wire Gauges
Heath explains the range of electrical wire gauges and how they vary depending on the load needed for a specific appliance. Electric current has a limited capacity dependent on the size of the wire. Circuits are available in different voltage loads to provide the exact amount of electricity required for a particular appliance. The larger the wire, the more current it can carry, meaning large wires support heavier electrical loads and smaller wires support lower loads.
Where to find it?
Electrical wire can be found at your local home improvement store.
How to Repair Flagstone Steps
Mark makes repairs to a 1960s flagstone entryway to ensure it’s safe and long-lasting. To address the loose stone at the top of the basement stairs, Mark recommends gently removing any loose stone pieces and mortar with your hands. Follow up by using a chisel and hammer to break away the old mortar to free the larger flagstone pieces. Use a masonry brush to clear any dirt or debris. For indoor masonry projects, Mark recommends using a Type S mortar premix that only requires adding water. For smaller repair jobs, mortar batches can be mixed in a rubber mixing tub in small quantities as needed. After applying a bed of mortar using a trowel, add construction adhesive to the bottom side of the stone before setting it in place. The adhesive will strengthen the bond as the mortar sets.
Where to find it?
To address gaps between flagstone floors and stair risers use silicone caulking. Mark recommends dipping your finger in blue dish liquid before smoothing out the caulk seam. This tip will help create a seamless finish.
