Question about Rheem 42VP75FW 75 Gallon Natural Gas Water Heater
How to remplace the Gas Control Valve of Rheem 75 Gallon, Model 42VP75FW ?
Shut off the water and gas to the heater. Drain the heater. Disassemble the gas line to the heater starting at the Union and working to the gas control. Disconnect thermocouple, burner and pilot tunes from the bottom of the old gas control. The old control will screw out of the front of the heater. Grab the entire housing of the control and twist counterclockwise to remove. Perform new gas control install and connections in reverse. Remember to apply at least 4 wraps of Teflon tape on all threads before assembly. (Teflon paste may be used) Do NOT put any sealant on the thermocouple,burner tube or pilot tube connections (these are compression connections, make them fairly snug.) upon completion, fill heater, turn gas back on relite and check for water or gas leaks

SOURCE: dripping from drain spout
If you are refering to the "Dripping coming from the preasure tempature valve,Then just turn off the valve where the water goes into the heater and open the P/T valve with a bucket below it draining only emought water to get below the level where it reaches. Normally the drain valves are plastic with a Male hosebib attached. Attach a garden hose to the rain and run it out to a point lower that the vaslve in order for gravity to drain the tank.The valve opens counter clock wise. If the valve is stuck or does not drain,and you have a foor drain handy,remove the whole valve and replace it with a boiler drain valve. If The tank is located below the drain level then you will have to either pump or carry the drain water to the higher level. Replace the P/T valve and reinstall the associated associated piping. I would use tefelon tape on the P/T pipe theads. You may have to open a hot water faucet in order for the air to replace the water in the tank ,in order to drain.

I answer questions for free.
My job is to provide resources that help you for free.
1) That being said, my research into FVIRs says you need a plumber when the FVIR trips.
2) The use-and-care manual for your model also says call a technician.
3) Buying replacement parts through a plumber is true for all water heaters except the Bradford White which has a resettable FVIR. BW is the only company with a re-settable FVIR, however the water heater market changes daily.
4) If the FVIR shorted and shut down the water heater, it probably saved a fire and maybe saved a life.
The following site says to call Rheem, who will tell you to call a local plumber.
The Rheem lineup of gas water heaters shows you have a 75 gallon tall heater:

The use and care manual has troubleshooting section > it says the combustion shut-off has to be inspected by qualified technician

Hello tiletnickm, first, the plumber's tape and bottle cap is very clever! GREAT JOB!
Many of those valves do have a stem that can be replaced, however, finding the right parts at the big box stores can prove challenging. If you have a local plumbing supply store they seldom have the part in stock, but can usually order the right part for you.
Something you may consider if you haven't drained your water heater in the past year, ( most manufactureres recommend draining them atleast once a year to prevent buildup and extend the life of the water heater ), it could be much less time consuming to drain the tank and then change the valve.
I hope this is helpful my friend!

Anode rods for tank-type water heaters are located on top of tank.
This is true since anodes are about 44" long.
Top of anode is standard 1-1/16" hex nut.
Anodes can be located in 2 different places: either directly screwed into top of tank -or- attached to hot water nipple.
Most times the exploded parts diagram in manual simply shows 'anode rod' without specifing exact location. If your tank has long warranty, then it can have two anode rods, and 1 will be on top and the other probably attached to hot water nipple, or there could be two anodes screwed into top of tank.
If anode is screwed into top of tank, then it will be under a plastic cap -or- it will be concealed under the top cover of tank.
Look for plastic cap, and if none shows, then remove screws holding down metal cover and look there for 1-1/16" hex nut.
Lastly, remove hot water nipple and check for anode located there.
If you have 2 anode rods, then replace with same metal for each.

Rheem does not post service manuals or bulletins.
It's how they treat customers. I do not recommend Rheem because of this problem.
They must expect their customers to pay for service call from Rheem-loyal technicians.
Here are resources that might help.
