Welcome to your Maintenance Assessment Name: The purpose of a vent pipe in a plumbing system is to Allow gas to escape Let excess water escape Let air in Both a and c Most ballcock assemblies can be repaired with a ballcock repair kit True False What can cause water pipes to vibrate and make noise Bad pipe straps A worn ballcock or toilet valve A loose faucet washer Both b and c What safety precaution should be taken when using a torch inside or near a building Evacuate the building Have wet rags handy Use flux and proper solder Have a fire extinguisher handy What kind of solder is used for potable water supply plumbing Non-corrosive 50/50 tin/lead Silver Lead free The purpose of a P-Trap is to Induce better drain flow Trap solids so they don't enter the sewer system Create a water seal preventing sewer gas from entering the living space Be an access point into the drain line PVC glue should be used in all plastic drain pipe compression joints to prevent leaks True False Faucet stem seats are made out of brass and never wear out Ture False You will find an over flow plate on a Washing machine Dishwasher Bathtub Swimming Pool A seat wrench is used on a Toilet Faucet Garbage disposal Water Softener Filter In the operation of a dual element (quick recovery) electric water heater The top thermostat needs to be satisfied before power is sent to the lower thermostat The bottom element is needed for high demand only Both thermostats/elements are energized at the same time for better heat output if one element burns out the other takes over The most important safety device for all water heaters is A tank pan piped to the outside to prevent leak damage A thermostat limit switch A temperature/pressure relief valve Copper or brass fittings to reduce heat stress The dip tube has perforations in it so cold water fills evenly into the tank True False A typical residential water heater element is rated at 240 volts and 4500 watts 120 volts and 4350 watts 240 volts and 7200 watts 240 volts and 2400 watts If the pilot light on a gas water heater will not stay lit the following could be wrong Clogged burner housing Bad thermostat Bad thermocouple All of the above Which of the following should not be done if you suspect a gas leak Turn on all lights to find the leak Open all doors and windows Turn off the gas main Remove residents from the unit when installing a water heater you must have a shut off on the inlet and outlet of the tank True False When replacing an element on an electric water heater the first step is Drain the tank Turn off the power Remove the element Turn off the water A thermocouple is used to Light the burner Detect the presence of the pilot flame Connect piping between the pilot and gas valve Connect steel pipe to copper pipe As a water heater is being filled up you should purge air from the tank True False Ground Fault Circuit Interrupter (GFCI) receptacles are used in kitchens, bathrooms and other potentially wet locations True False When replacing a breaker you must use one that has an amp rating the same or higher than the one being replaced True False An uninterrupted or continuous path for electricity to flow from one point to another is called Resistance Voltage Overload Continuity 12 gauge wire is rated for what size breaker 30 amp 15 amp 20 amp 12 amp Electrical resistance can be measured by Amp meter Volt meter Watt meter Ohm meter Which are the following statements about the "ground fault current interrupter" (GFCI) are true It detects accidental groundings in an appliance or tool If a ground occurs, the GFCI will disconnect the circuit in 25/1000 seconds The national electric code (NEC) requires GFCI on all 15 and 20 amp outdoor receptacles and on all bathroom receptacles In 1978 NEC required all GFCI on all receptacles A, B and C If a receptacle has 1 red, 1 black, 1 white and 1 ground it usually indicates it is A 220V receptacle Half the switch is controlled by a switch Wired incorrectly Is wired in series with another receptacle If a fluorescent fixture makes a loud humming noise, the most probable cause is Loose connection Bad bulb Bad ballast Bad switch When replacing a fused disconnect at the A/C condensing unit, what precaution should be taken Notify the electric company No procedure is necessary Lock out tag on the controlling breaker Recover refrigerant The device that turns on outdoor lighting when it gets dark out is Motion detector Photocell Circuit breaker Switch You receive a service request for a frost free refrigerator not cooling properly. Both fans are running but the evaporator coils are packed with frost. A possible diagnosis is Clogged filter/dryer Unit has a low refrigerant charge Defrost timer is defective Condenser coil dirty One surface element in an electric range will not get hot enough. What could cause this problem Bad breaker Bad infinity switch Element burned out Bad thermostat An oven bake element reads 18 Ohms resistance. Is this a good element Yes No A proper ground is made to a dishwasher when the water line is connected True False You receive a service request on dishwasher that is leaking out the front panel. What could cause the leak Bad hub components or lower wash arm Resident used a soap type other than dishwasher soap Float is stuck All of the above When you try to operate the disposal you find it hums but does not run. You should then do the following Check the reset switch Manually rotate the blades Poor cold water in the drain Replace the disposal Dryer runs and heats but will not dry the clothes, the likely cause is Vent line disconnected Bad heater Bad sensor switch Plugged vent line Your new question! A washer machine does not fill with water it is possible the problem is with the motor True False If the condenser fan motor fails and the unit continues to run, it will cause The evaporator to freeze up The low pressure safety switch to open up Sweating of the liquid line dryer High head pressure In a R-22 charged split air conditioning system a possible correct operating pressure is 40 low 120 high 70 low 275 high 95 low 175 high 40 low 325 high What could cause a compressor to ice up High head pressure Undercharged system Restriction in the liquid line dryer Overcharged system The large refrigerant line on a condensing unit is the suction line True False All gas furnaces use a pilot light to ignite te burner True False A heating unit does not operate, but when you jump the red and white wire at the thermostat and the heating unit works, which one of these controls is defective Limit switch Transformer Gas valve Thermostat What is the ideal PH reading in a swimming pool 6.8 6.2 7.4 8.6 What chemical should be added to lower the PH level Soda ash Chlorine Muriatic acid Stabilizer Prolonged PH imbalance is safe for plaster but can hurt metal parts True False What is the result of pool water that has excessive amounts of stabilizer Water needs stabilizer reducer Chlorine is locked up/ineffective Filter dome pressure is high Water needs algaecide Self closing and latching pool gates need to be inspected daily True False Time's up 100 Orndorf Dr#756Brighton, MI 48116(734) 747-6278 FollowFollowFollow Solutions About Us Events The Proof Smart Store Blog Staffers Contact © 2023 Smart Apartment Solutions.
