Question about Rheem 82V40-2 Fury Electric Residential Water Heater, 40 Gal

1 Answer

Relief valve buzzing noise

I have a Rheem electric hot water heater model number 82v40-2, the pressure relief valve makes a buzzing noise and releases water. Once I flip the lever to release any pressure, it stops. This happens after I use hot water (shower, laundry) at a certain point it will stop. This was happening before about 2 weeks ago, than stopped. I replaced the pressure relief valve one day ago with the exact replacement, that did not work. I changed the upper and lower thermostats with OEM Rheem thermostats, same problem. After changing the Pressure relief valve I did bleed the system in the three rooms that has hot water. The hot water heater is 7 years old, I drained the water level just below the pressure relief valve before changing it and I did not see any rust or contaminants in the water. I also reduced the temperature to about 100 degrees Fahrenheit. What next? Eddie

Add an extrol expansion tank to the piping. You can get one for about thirty dollars from the hardware store.

lower your thermostats a bit. If your temperature is set to the hottest setting, then chances are no relief valve will do

SOURCE: Water Heaer Problems

Although rare the pipes may both me hotter near the heater and the cold water line will get colder the farther back you go from the heater. Now I would do yourself a favor and hire another plumber to do the work on your water heater because from what your telling me these guys don't know anything about water heaters and I suspect they may have bumped your TPR valve (although if you ask them I'm almost positive they'll deny it). Here's what happens. From not be being used all the time the TPR valve gets buildup in it from your water lines, and as soon as the lever is pushed the TPR valve will constantly leak water until it is replaced. I would try replacing that first. To replace it simply unscrews with a wrench, just be sure to turn your water heater off and drain it halfway before replacing. That is the least expensive option. Next I would try putting in an Amtrol Expansion tank. Your local home store can get you the right one. It expands when there is excess pressure in the line. A plumber would have to install this and if you already have one make sure it is working properly. These are the only two things that would make a TPR valve leak. So while the two are not linked, I still don't think it is a coincidence.

Sounds like a plumbing problem.

Since no tap gets hot water, chances are good the problem lies in the hot water pipes between the water heater to the first Tee.
Look for sediment lodged in water heater hot water pipe.
Or sediment lodged in elbow or Tee.

Other problems can be in play.
Faulty check valve or mixing valve if these are installed.
Faulty recirculation system if this is installed.
Also crossover at single-handled faucet where the cartridge is bad and lets the cold water flow into hot water pipe whenever another faucet is turned on. If you are getting cold water out the hot tap, and you know the hot water heater has hot water, then crossover is suspect > in addition to sediment blockage at hot water heater.

My pressure relief valve keeps blowing more so when it is hot any ideas please


Pressure relief valves open on high temperature as well as high pressure. They do go bad and are replaceable.

Consider calling the plumber. It is not very expensive part and the plumber can change it quickly.

If you just want to do it yourself:
  1. Write down the make and model of the water heater.
  2. Go to a real plumbing store and buy a new one.
  3. Turn off the heat source (the gas or electricity)
  4. Turn off the water inlet and open a hot water valve at any sink to take the pressure off the heater.
  5. Remove the old relief valve. It may take a long handled wrench.
  6. Install the new pressure relief.
  7. Close the sink valve.
  8. Turn on the water and check for leaks.
  9. Turn on the heat source.

Good luck.

Pressure relief valve intermittent noise


check your water pressure and then make sure it is not to high or all the problems you have had were not the answer. it is a pressure /temperature valve not just . temp.

I have a 21v407 Rheem water heater that is leaking from the top relief valve. The leak i believe, is from under the valve. what is this problem. and how do u drain this thing?


Shut off the water supply valve over the heater. Shut off the electric or gas to the heater.
If you have any house or basement water valves below the level of the heater, open them and open a valve that is higher to vent it.
If necessary, open the drain at the bottom of the heater and using hose or buckets, lower the level below the relief/thermostatic valve. Be careful, the water is hot and softens even heavy hoses.
Once the water level is down, unthread the downtube (if there is one) from the discharge of the relief valve, unthread the relief valve from the heater and either dope/tape the threads or replace the relief valve.

Write back with any questions.

WATER IS LEAKING OUT MY PRESSURE RELIEF VALVE. IT SEEMS LIKE THE WATER IS GETTING TOO HOT AND IT IS CAUSING THE RELIEF VALVE TO OPEN UP. WHAT WOULD CAUSE THIS? WOULD IT BE A BAD RELIEF VALVE, A BAD...


If you have overheating, the elements are working fine and are not suspect.
Also electric power and circuit breaker are eliminated.
ECO reset is not tripped, so that points to faulty TP vlave, but water temperature has to reach 180 degrees F for ECO to trip.
Open link to see ECO located on upper thermostat.
http://waterheatertimer.org/images/Jly-022-thermostat2-175.jpg

Remaining suspects are 1) bad thermostat or 2) faulty TP valve or 3) Stacking or 4) combination of the 3.
Raise TP lever and gently let back down and see if something was lodged in the valve.

1) If you are certain that water feels hotter than normal, then replace both thermostats:
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
http://waterheatertimer.org/How-to-troubleshoot-electric-water-heater.html

2) If water seems normal temperature, then replace TP valve:
http://waterheatertimer.org/How-to-replace-TP-valve.html

3) If TP releases water after frequent water use, then Stacking could be part of problem:

How do i replace the heating elements of a rheem model 71-305 electric water heater


Not familiar with this model but most are generic.
Turn the water off;
Release the pressure with the pressure relief valve and leave it open;
Undo the cold water inlet assembly and drain the tank;
Disconnect the element wires from the thermostat;
The elements are held in by 4 bolts. Undo the bolts and remove element;
Installation is the reverse of above.

Pressure releif valve leaking


Hot water pressure relief valves serve two functions. The first is to remove high-pressure water from the hot water tank. The second function is to act as a high temperature valve to remove water that exceeds a predetermined point for the valve. Both of these relief settings are preset at the valve factory. Many pressure relief valves will come with a metal tag that identifies these release points. If you're attempting to remove the hot water heater pressure relief valve, pay careful attention to ensure that you replace with the correct valve.

Your hot water heater has a pressure relief valve safety mechanism. When pressure inside the water tank exceeds certain limitations, the valve opens up to allow the pressure to be released. A faulty pressure relief valve will not release excess pressure, which could cause extensive damage to your home. You should test the hot water heater pressure relief valve once every six months to ensure proper operation. If the pressure relief valve fails the test, replace the valve with a new one immediately

Locate the pressure relief valve on your hot water heater. The pressure relief valve has a lever handle on top with a drain pipe attached to it. The pressure relief valve is most often on the side of the water tank toward the top. Newer models of hot water heaters have the pressure relief valve on top of the water tank.

  • Inspect the area around the pressure relief valve for signs of leaking water. If there is leaking water near the relief valve connection, replace the relief valve. If no leaking is evident, proceed with testing the pressure valve.

  • 3

    Examine the area below the pressure relief valve drain pipe. Most water heater closets either have a drain in the floor below the pipe or the pipe is inserted into another pipe to direct the water out of the home. If the end of your drain pipe is not in another pipe or there is no drain in the floor, place a bucket under the drain pipe to catch water when you test the pressure relief valve.

  • 4

    Pull the lever handle on the top of the pressure relief valve up with your fingers. A working lever will lift up without difficulty.You should begin to hear water going through the drain pipe. Slowly release the lever to shut off the pressure relief valve. The pressure relief valve is good. If you did not hear water running through the drain pipe, lower the lever on the pressure relief valve and replace the valve. If the lever is difficult to raise, do not force the lever. Replace the pressure relief valve.


  • Now with all that said if you have a closed loop water supply system and you have a pressure vessal/expantion tank it may have gone bad and is making the TP valve leak. you can call your water provider to see if you have closed loop system.

    We have a brand new rheem 40 gal elec water heater, after installation we have water leaking from the base of the relief valve, pooling up in the plastic fitting and making it way over the side all over...


    Water heater should be set in a drip pan.
    Otherwise, put 1 gallon bucket under TP release pipe to catch water.
    http://waterheatertimer.org/Water-at-bottom-of-water-heater.html#drip-pan

    When you say relief valve, I assum you are talking about brass valve located on top of tank or near top of tank. This is TP valve and a pipe connects to this valve and runs down to within 6" of bottom of tank. TP valve has a small lever on it.
    If you are talking about tank drain valve located at bottom of tank, then add a comment.
    Following information is for TP valve.

    Dripping TP valve can be caused by 3 different thing:

    1) Obstruction inside TP valve. Open TP valve for a moment to flush away particles and slowly lower lever back down. See if water stops dripping, if not, then replace TP valve

    2) Defective TP valve: replace TP valve. Turn off electricity to water heater. Let heater cool for several hours so you do not get scalded. Close shut off valve located above tank on cold side. Open tub spout to relieve pressure, open tank drain or open TP valve and empty water below TP valve level. If TP is located on top of tank, not much water has to be drained. Tank is under press when hot, so be careful. Put teflon tape on new valve and install with big pipe wrench by turning clockwise until TP valve is very tight.

    3) Overheating tank. TP valve is temperature-pressure valve. If tank water is over 150 degrees, the TP valve starts drizzling hot water to relieve tank pressure.
    Lower tank pressure two different ways:
    a) turn down thermostat
    http://waterheatertimer.org/How-to-adjust-water-heater-temperature.html
    b) install expansion tank on incoming cold water line

    Pressure valve releases sometimes , I lose a good bit of water. When i tap the valve handle, it shuts off.


    The pressure release valve is a safety feature. If it is leaking alot, it could be that the valve needs to be replaced or it could be that the high temp. shutoff in the hot water tank is malfunctioning.
