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.

I have a vulcan 260 which has water leaking from a pipe outlet at the bottom left hand front corner ( facing the heater). It has never done it before.


ruthpietsch-

My guess is outlet you mention is the pressure relief valve on your water heater, which is designed to prevent the water pressure in the heater from exceeding the limits of the unit. That the relief valve is releasing a little water is not necessarily a sign that something is wrong with the heater, but if the leaking continues regularly for an indefinite period, I recommend contacting a licensed service technician.

Hope this helps.

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

    b) install expansion tank on incoming cold water line

    Just purchaced a 99 jamboree with an atwood G6a-8e water heater. while on a trip I lit the water heater, and after 30 minutes someone told me water was leaking from the side. I noticed the pressure relief...


    It's gas operation only, but has electronic ignition for propane. ( just to confirm, if you look at back of water heater, it would have a metal or black plastic cover and hydro cable going in side or top of it.)
    There are usually 3 things that may cause pressure relief to leak. 1) Faulty,corroded pressure relief valve, which usually needs to be replaced if it goes faulty. 2) water temperature is getting too hot, which could indicate a faulty thermostat. 3) If your hooked up to city water, the pressure may be too high, causing excess pressure build up in hot water tank, thus pressure relief opens. If your running off your on board pump, this is probably not the cause, as they are usually set at 40 psi.
    Ist, - try pulling lever on relief valve slightly open ( careful it's hot !!) to clean out any calcium that may be logged on seal thus causing leak. If that doesn't do it, and the hot water isn't running out steady and appear to be under extreme pressure while leaking, then I'd change the pressure relief valve. Remember when you do, shut off water to system, and relieve pressure by opening a tap, and pressure relief as well after that. New one shouldn't be too expensive, just make sure you get same thread, 1/2"NPT or 3/4"NPT. Use a little teflon tape, or pipe dope whatever you prefer when re-installing as well as clean threads a little before.
    If it really starts gushing out pressure relief when heating or heated, and water seems hotter than normal, it's more than likely a faulty thermostat. I'll wait for your reply on what condition your experiencing before I go in to how to change the thermostat.

    I have a Reliance 501 40 gallon water heater leaking warm water from the valve at the top of the unit. Steady leak. What should we do short term, and is there a part we can get to fix it?


    i am not sure if you are talking about a shut off valve or the pressure relief valve. the relief valve should have a pipe from it going down the side of the water heater. if that is the leak the it can be replaced. there should be a little lever on top of it and some times by lifting it and letting a little water flow through, it will stop leaking.

    Pressure relief valve


    The pressure relief valve only leaks when there is excess pressure in the system, possible causes could be excessive static pressure, overheating, faulty pressure vessel or undersized pressure vessel.

    Leaking pressure relief valve


    what is the water pressure on the cold side? You may need to install a pressure reducing valve at the water heater inlet to reduce inlet pressure and keep pop off valve from opening when not needed.

    Too much water draining from Vulcan Electric H/W relief valve.


    Dear Julie. Do you have an expansion tank installed? If so it is probably waterlogged. If you come home shower etc. use lots hot water then go to bed or leave the cold water in your tank heats and expands as it heats. In the old days a toilet ballcock valve would relieve this pressure but modern toilets with diaphragm valves wont so the pt valve relieves pressure. Installing an expansion tank on the cold water line near the heater will absorb the extra water & stop the pt valve from activating.

    Hot water coming out of overflow pipe on my vulcan everhot water


    Assuming you are talking about the temperatur/pressure relief valve, it is stuck open.

    1. Turn off gas or electric to water heater
    2. Close water supply to water heater
    3. open hot water faucet on nearest fixture to depressurize hot water system.
    4. close tpr valve (you may have to push in on the center spine. It may be resistant to closing from sediment. If so, opening and closing several times may solve that issue.

    Once you get the tpr valve closed, close the faucet and open the supply valve. If the tpr stays closed, go ahead and turn on the gas/electric and re-light pilot and turn on control etc.

    If the TPR blows again, you will need to replace it. YOu can buy a new one at any plumbing supply store. Shut down the heater again, drain a bit of water out using the valve on the bottom of the tank. there is probably copper pipe connected to the TPR valve which you may have to cut or maybe can just unscrew. The TPR threads out of the tank, install the new valve (make sure to use pipe dope or teflon tape.
