Troubleshooting
This component often fails due to misalignment, overloading, or lack of lubrication.
What is bearing
This valve setting should be used when you want to clean the filter by reversing water flow.
Backwash
You use this device to check voltage, continuity, and current in circuits.
What is a multimeter
This valve controls the entire water supply to a building and is the first thing to shut off during a major leak.
Main shut-off valve
This part of the HVAC system is often cleaned to prevent mold buildup and improve drainage.
Condensate drain line
This is the unit of electrical power.
Watt
These items are commonly replaced in faucets to fix a leak caused by worn-out seals.
O-rings
This tool detects the presence of refrigerant leaks using sensors.
electronic leak detector
What is the IDEAL Ph range for a pool?
7.2-7.8
A blown fuse or tripped breaker is most often a sign of this kind of problem.
What is an electrical overload
This power tool spins a cable to break up or retrieve clogs deep inside drain lines.
Auger
This pair of gauges is used to measure high and low-side refrigerant pressures.
manifold gauges
If the pump runs but no water is moving, check for this common problem at the skimmer.
Clogged basket
This wrench, designed with a serrated jaw, is commonly used to grip and turn pipes.
Pipe wrench
This component starts the compressor and fan motors and is commonly tested for continuity and capacitance.
Capacitor
If your dishwasher starts, fills with water, and drains. However it is not cycling what is wrong with it?
What is a circulation motor/pump
HVAC systems use this to convert a low-voltage signal into an on/off command for the compressor or fan.
Contactor
