Question about Rheem 50 Gallon FVR NATGAS Water Heater 6YR 22V50F1

1 Answer

The pilot was out this morning and after I got it started, I got

Water pouring out of what I believe is a pressure relief pipe. This was several hours after I got it going. It is a copper pipe that runs down from the top of the heater and has no type of coupling on the end. The water was very hot. It was much more than a leak. We turned the heater off and shut the water off to the house before it would stop pouring out of the pipe.

Hi jeake9,

Yes, you are correct it sounds like the pressure relief valve. It is an important safety device that lets water out of the water heater when temp/pressure exceed the limit set on the valve. It did its job good.

Now the important part is to change out the valve and try to diagnose why it tripped. Odds are the water temperature was too hot AND the relief valve couldn't close because of mineral deposit build up.

Replace the relief valve and turn the water heater down for starters.

Water dripping from blowpipe


It is normal for water to drip out sometimes from the pressure relief valve outlet pipe. If it drips continuously then open and shut the pressure relief valve several times so the pressure relief valve shuts off properly.
If this does not fix the dripping problem then the pressure relief valve is faulty and needs to be replaced.

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.

    Water is pouring steaming hot water from a copper pipe on the outside of my GSW Series 6 40 gallon water heater onto my basement floor. What is wrong?


    Sounds like the TP valve is releasing water.
    http://waterheatertimer.org/Water-heater-leaking.html

    To protect your property right now, turn off water heater:
    Gas: turn gas valve to pilot so pilot light stays lit but burner will not turn on.
    Electric: flip circuit breaker off

    Next turn off water valve located on cold water line above water heater.
    Last, open tub faucet to relieve pressure on tank.
    Once pressure is off after a few moments, close tub valve.

    The question is why is the TP valve releasing water.

    1) Stuck TP valve: raise lever on TP valve and let back down slowly

    2) bad TP valve: replace TP using same temp-pressure rating available from hardware store. Wrap teflon tape around threads and screw new TP valve clockwise until very tight. Make sure water is cool before removing valve from water heater. If you take out valve when water heater is hot, it will spew scalding water all over you. This is serious. Let the water cool down for several hours.

    3) Runaway heating caused by bad thermostat
    Gas: buy replacement valve at Lowes or plumbing store and replace according to instructions.
    Electric: several causes. Test parts to determine which needs replacement.

    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

    Over flow leaks constantly after 8 years, never done this before. What should we do?


    As long as the heater is still working good and not leaking I would just replace the Temperature and pressure relief valve. To do this turn control knob on gas valve from on to pilot. This will maintain pilot so you won't have to relight later while keeping the burner from firing while you are replaceing t&p valve. Turn off water supply on cold water supply to water heater.If this valve won't work or you don't have one shut off supply to house. Do not attempt to remove t&p valve until you are sure water is off. Open hot water on faucet close to heater and drain a few gallons from water heater drain valve. Purchase new t&p valve at hardware store. They are pretty standard 3/4 inch male pipe thread, 150 p.s.i. rated. Use teflon tape to seal pipe threads ,4-5 wraps at least or pipe joint compound to seal threads You will need a pipe wrench to remove old valve. Turn it counterclockwise to lossen then remove. Have new valve ready to go to minimize water loss. Be carefule as water will still be hot. Install new valve and tighten securly. Turn water back on and check for leaks. Also shut off faucet you opened. Once you are satisfied there are no leaks turn gas valve to on and bleed air from several places. I hope this helps you. Thanks.

    MY GE PRESSURE RELIEF VALVE HAS JUST STARTED LEAKING. WHAT SHOULD I DO ? GE SMART WATER HEATER GELN0705CO3984


    Hello,
    You can buy a replacement relief valve at any hardware or home improvement store. It's real name is a T&P valve or temperature and pressure relief valve. It always has a 3/4" inlet and outlet. It is a very easy procedure to replace. You will need a bucket, teflon pipe thread tape, and a 3/4" x 6" black iron or galvanized pipe nipple. To start the valve replacement, turn off the shuttoff valve on the cold water line. Then open the handle on the relief valve and drain water into the bucket, that is, unless you have a pvc pipe coming off of it into a drain floor, then just drain it without the bucket. Be careful, the water is hot! When the water level gets below the relief valve, it will stop draining. Then remove the pvc pipe, if applicable, and thread in the 6" pipe nipple to use as a leverage tool to remove the valve from the water tank. Turn it counter clockwise to remove. Then put teflon tape on the new valve, going from left to right with the valve threads facing downward. Wrap about 3-4 layers all around the threads. Then twist the new valve into the water tank clockwise and using the pipe nipple tighten by hand until very snug and outlet is facing downward, as before. Remove the pipe nipple and install pvc pipe, if applicable. Leave valve handle open and turn on the cold water until the valve starts spitting, then close the relief valve and let it fill up the tank. If you did it correctly, you are now finished! Good luck!

    Relief blowing out hot water every hour or so. Controller? Set at about 125.


    try replacing the pressure relief valve to do so turn off water to heater and turn off power or gas which ever you have drain water from heater. then using pipe wrench remove old relief valve. when installing new valve use teflon tape on threads to prevent leaks then thread by hand back into water heater and use pipe wrench to snug dont over tighten turn water back on after full and no leaks turn power back on or relite piolit

    My water heater is pouring water out of the overflow hole, I turned it off but how can i fix it?


    Your pressure relief valve is open either due to an increase of pressure (that is what it is designed to do) or more likely .the spring in the device is weak and requires replacement . pick one up at Lowes and reinstall the same as removal .You will need a pipe wrench or equivelent and some pipe sealing compound.Hope this helps.
