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.

SOURCE: Drain Valve on bottom of water heater drips when Water IN turned

If the hot water heater is gas be sure it's turned off same if it's electric so you don't burn out theelements in the tank, I would advise you to buy some plumbers putty and pull the drain scre out and put putty in it then reinstall the screw. all the ones I looked at I could not tell by looking to see where the drain was and if it has like a hose bib on it or not. also pull the screw all theway out and see if you got some sand in the valve and if so use some compressed air in a can to blow the stuff out of the seating area of the screw. Hope this is helpful would be nice to have a picture of the drain.

SOURCE: Dripping Drain valve on rheem water heater

If your water heater is 10 years old or more, it's much better to replace the entire thing before you start having additional problems with it. You MAY be able to drain your water heater and replace the valve with something more reliable, but, as I've said... if your water heater is old, this is just the 1st thing to go wrong. More will follow.

Drain valve leaking. Gor replacement part. Cannot get old valve off . Does the whole valve come off , unscrew or pull off? serial number is RN1296A 18392. Will the new part fit the same New...

If valve is dripping, buy garden hose cap and screw onto valve.
Whole valve unscrews counterclockwise.
If valve is plastic, expect it to break off.
If valve is brass, use cheater bar on your pipe wrench.
I don't know that serial number or part number, but drain valves are standard 3/4" pipe thread.
http://waterheatertimer.org/How-to-replace-water-heater-drain-valve.html

Drain valve can be rusted in place and impossible to remove without draining tank and putting water heater on it's side.
Install new water heater so drain valve is accessible, and buy new water heater with brass valve instead of plastic.

I just noticed that my hot water heater that is 6 years old is dripping very slowly from the bottom faucet, how can i stop this leak. thank you.

If you mean the drain valve, then buy garden hose cap at home center.
Cap will have rubber washer that seals tank.
If drain valve is plastic, the cap may not thread on without sanding down end of plastic drain valve.
Otherwise replace drain valve, which is simple if drain valve is brass, but can be difficult if drain valve is plastic.
Turn off power to water heater: Electric: turn off circuit breaker. Gas: turn knob to pilot.
Turn off water, open bathtub spigot on Hot side, drain water heater, remove drain valve with wrench.
If plastic drain valve breaks while being removed, then 'gently' break out broken part using hammer and big screwdriver.
Buy new drain valve at box store in water heater department.
Put teflon tape on new drain valve threads.

I need to replace the drain valve at the bottom of the tank,can I buy a replacement valve? Are they all the same size?

There are 2 sizes; 1/2 inch and 3/4 inch. Remove the old one after draining the water heater and shutting off the water supply then take your old one to a plumbing supply outfit like George Morlan's. Make sure you wrap the new threads with teflon tape at least 3 wraps while holding the spigot in your left hand so the tape won't come off as you install the spigot. Good luck!!

Slight water leak from plastic drain fitting on rheem fury 40 gal gas water heater

You can try to crack it open and get a little piece of crud out of there, I'm sure that is all it is, Just get a tray or something to catch the water, It should stop it, If it gets worse, turn the water off to the heater, then open the valve and hope the bigger piece of crud comes out. It is about all you can do, other than drain the whole thing and take the valve apart and replace the rubber in it. Check it out, Hope this helps.

There is water constantly draining through the drain valve.

Grab a cap from the hardware store to stop it on the cheap. If it it is a brass drain valve you may be able to get away with draining the tank and replacing the small washer inside. Replacing the drain valve will be the ultimate solution.
Turn off the power on and electric or shut the gas valve to its off position.
Turn the water supply off above the tank or at the house main.
Connect a garden hose to the drain and open it all the way.
Open the safety valve on the top or side of the water heater to allow air in the tank so it will drain faster.
Unscrew the old drain valve with a pipe wrench.
Wrap plumber's teflon tape clockwise around the threads of the new drain valve and screw it into the tank by hand.
Tighten the valve with your pipe wrench until it is facing down at a 45 degree angle.
Close the safety valve.
Turn the water back on.
Open a faucet or two in the hows to let the air out of the tank while it is filling.
Turn the power or gas back on ONLY after the water heater it filled with water.

What cause the water heater to take more than an hour to heated up and unable to last longer. Usually its take about 15 min. to heat up and can last longer.

'Rheem 81VP15S point of use' is a single-element, 15 gallon, 120V electric.
Other 'point-of-use' sizes range from 2-1/2 to 6 gallon to 20 gallon.

Electric water heaters have 2 parts: thermostat and element. One is not functioning correctly. Most likely the element caused by sediment build-up.

How to determine if tank has element or thermostat problem:
Do not turn off water going into tank. Put hose on drain valve. Open drain valve. Does water come out like open spigot? If water does not flow, then heater is likely clogged with sediment.

Solution 1: If water flows out like a spigot, the thermostat is probably bad. Read: How to replace thermostat.

Solution 2: Water does not flow, so element is surrounded by sediment build-up and cannot heat water. You need to clean out tank with shop vac, and put in new element ... plan full day and 3 trips to hardware store. Simply draining tank will not remove sediment. Sediment is chunky and will not come out voluntarily.

Buy element before starting:
-Turn off electricity
-Open cover on side of tank, remove insulation (these have to be put back for proper operation of thermostat)
-The are 2 electrical parts >>the element and the thermostat which is located above element
-Element wattage is printed on element and also shows on label on side of tank
-I think Rheem element is held in place with 4 hex bolts
-Take photo of element to hardware store so you have part on hand before removing old element
-If element is 1-1/2' diameter hex type, you need inexpensive element wrench from hardware store + the element

Drain tank and clean sediment:
