Possible problems not knowing age of unit the
control valve could be sticking open allowing gas to continue to flow until high limit is reached and shuts down valve another possible problem with the newer style back flow preventer being install by water companys the rapid heating and expansion of the water over pressures the water system causing releif valve to pop open and reclose most water heater manufacters are recommending instalation of an expansion tank to allow the growth in volume of water somewhere to go is valve constantly leaking or only during heating cycle if you could supply additional information does unit only leak when heating
or is steam expelled when releif valve opens
t-stat not opening gas valve sticking partially open
bad high limit bad pressure releif valve no expansion tank to allow for thermal expansion if steam is present and unit is boiling water inside replacement of water heater for safety concerns,would be reccomended if only water and pops couple of times water temp not over 140 degrees after most hot water has been used out of tank and is reheating most of capacity probably lack of expansion tank as the releif valve is the final safety device on a water heater is of great concern
the temp control gas valve or high limit are supposed to shut unit done long before the safety limit of releif valve is reached

Low flow trough the heater


follow this steps and fix it. God bless you
Drain a tank:
  1. Shut off power at the electric panel and post a sign warning others not to turn it on.
  2. Close the cold-water supply valve and open a hot-water faucet somewhere in the house (to speed draining).
  3. Attach a garden hose to the drain valve and run it outside the house.
  4. Open the drain valve and allow all water to drain out.
  5. To refill the tank, close the drain valve tightly and open the cold-water supply valve. Also open a nearby hot-water faucet. When a steady stream of water flows from that faucet, the tank is full and the faucet can be closed.
  6. Once the tank is full, turn the electrical power back on.
Test and replace a relief valve:
  1. Lift the spring lever on the valve to fill a small cup. Check the cup for sediment.
  2. If no water spurts out, or if water continues to drip after the valve is released, replace the valve.
  3. Cut power at the electric panel and post a sign warning others not to turn it on. Close the cold-water supply valve.
  4. Drain a few gallons of water from the tank.
  5. Unscrew and remove the discharge pipe if used.
  6. Loosen the relief valve with a pipe wrench, then remove the valve by hand.
  7. Apply pipe tape to the threads of the replacement valve and screw it into the tank by hand. Tighten it with a pipe wrench. Screw the discharge pipe (if any) into the valve outlet.
  8. Refill the water heater and restore electrical power.

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.

    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.

    Have no hot water pressure at all but the cold works fine


    Check the inlet valve at the water heater to make sure that it is open. If yes, check and see if the safety relief valve (sometimes called the T&P valve) is discharging water. If it is, replace it with an exact replacement from any hardware store. There's a picture of one (above). You'll need to shut off the water valve to the tank and drain the level down with a water hose routed to the outside. Don't forget to take an air bleed. Take your old one with you.

    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.

    Water just gets luke warm on propane or electric. has electronic ignition, do i need circuit board? Atwood 6 gal. tank


    Run it on propane and let water heater go through a heating cycle, and when it shuts off, CAREFULLY , pull the lever on the pressure relief valve slightly and see how hot the water feels there. If it's hot there, then it's more than likely a problem with your by-pass valve(s) at the back of the water heater. Either in the wrong position, or faulty, and allowing hot and cold to mix. If in doubt which one it may be, you may be able to remove by-pass set-up completely, depending on what system you have. What the ultimate goal is would be to attach your incoming cold line directly to bottom fitting of water heater, and outgoing hot line, to the top. Not unusual in some systems for one of the shut-offs in between the 2 lines to stay partially open, and allow cold to mix with hot, thus -warm only. If it's not hot at pressure relief valve, then I suspect a faulty thermostat, but that would mean they both (hydro and gas) would have to be faulty which is unlikely.

    I own a 31' trailer which has an ATWOOD G6A-8E RV Water Heater, 6 Gal electronic ignition, 2 yrs ago the pressure relief valve would open up and empty the hot water tank completely, it did this several...


    Most electronic ignition models only show the red light if there is a problem, (did not ignite) for one reason or another. To start with, make sure your propane is on, and you have a good flame at stove top burner, just to be sure the water heater is getting propane, and all air is bled from the line, which may cause water heater to go into check. (red light) If it does, shut switch off, and retry. Let me know what happens. As far as pressure relief opening and emptying the water heater, and your sure it's not a faulty pressure relief valve, then there's 2 things to start with checking. 1st, does the water seem extremely hot, thus a possible faulty thermostat &/or ECO . Secondly, if the incoming water pressure is too high, that will also cause it to leak bad. Try installing a pressure regulator (usually 40 psi.) at your hose connection. Let me know what you find.

    My refilled 60 # propane tank leaked and then stopped flowing.


    Rick, if the tank is normally plumbed for a horizontal position, and you have it standing vertically, then you are feeding liquid propane to your pilot light, hence the frosted hose etc., and a tendency for the pilot light to go out as it has too rich of a fuel to burn. There should be no vent to allow air in as propane is pressurized, and only attains zero pressure at 40 below zero farenheit. The valve you speak of should have been the liquid vent valve which is used during filling only, and is closed during any other use. Your supply valve should be in the wide open position. The pressure relief valve is only operational when the tank has been overfilled or overheated. You should have a pressure regulator between the tank and the appliance you are trying operate. Hope this helped. Marvin
