Learn about the internal components of a water heater, including the pressure relief valve, anode rod, fill tube, and heating elements. Understand the importance of the anode rod in preventing corrosion and how deterioration affects tank longevity and function.

Learn how dual-element water heaters operate and how to diagnose heating issues. Covers testing thermostats and elements for continuity, safe replacement practices, and warnings against dry-firing elements.

Learn how to replace a toilet’s wax ring, including removing the toilet, scraping the old wax, installing new closet bolts, properly seating the new wax ring, sealing, tightening bolts, and checking for leaks. Also covers optional tank component rebuild during disassembly.

Learn how to test calcium hardness. Fill to 25 ml, add 20 drops of R10 and 5 of R11—sample turns red. Add R12 drop by drop until it turns blue. Multiply drops by 10 for ppm. Ideal range: 200–400 ppm (optimal: 300–325 ppm) to protect surfaces and grout.

Learn how to install and use a chlorine tower. Connect the “in” line from the pump and the “out” line back to the pool. Fill with 1" or 3" chlorine tablets—never use granular chlorine. Lubricate the cap gasket with silicone gel and tighten the cap before starting the pump. Always turn off the pump before opening the cap. Use the dial to maintain 2–4 ppm chlorine, aiming for 3 ppm.

Learn how to maintain ideal chemical balance in a pool, calculate pool volume and water loss, and understand how these factors impact chemical dosing and leak detection. This foundational knowledge helps ensure water quality and reduce unnecessary costs

Learn how to operate a multiport valve and understand the purpose of each setting—filtering, backwashing, rinsing, draining, and more. This video also explains key safety tips to prevent gasket damage and ensure smooth system operation

Learn the parts and operation of a pool pump, including the motor, impeller, and skimmer basket. Understand the importance of keeping the basket in place to prevent clogs and filtration issues. Learn safety steps for cleaning and how to match motor specs when replacing. Troubleshoot starting issues by testing the capacitor.

Learn how to monitor and adjust salt levels and chlorine output using a salt generator. Check flow direction and clean cells when needed by soaking in a diluted muriatic acid solution. Maintain proper salt levels by adding salt evenly and brushing the pool bottom. For cold weather, switch to chlorine and unplug the generator to protect the cells.

Learn the proper steps to reactivate a pool system after winter. Reinstall the pump and filter plugs, pressure gauge, and sight glass. Open all valves, fill the pump with water, and prime the system using the “Waste” setting. Then backwash, rinse, and switch to “Filter”—always turning off the pump between setting changes.
