Presumably you are referring to a water leak - not gas. The pooled water could be condensate from a "sweating" pipe but, depending upon the age of the heater, it may be time to replace it

SOURCE: Reliance gas water heater 40 capicity, has a leak on the top

Most likely only one of the pipes is leaking but weaping enough to cover the top and indented places near both inlet and outlet. This leak has most likely penetrated all the insulation and is a problem throughout the tank wrap insulation...If you are able to blow air continuously long enough to determine which connection is leaking then fix it. It will likely to take quite a while to dry out all the insulation if the water has migrated down into the tank wrap... If you determine that the insulation is waterlogged, you may be able to drill several small holes in the external cover.
good luck

SOURCE: Relief valve constantly releasing water.

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

SOURCE: I have water leaking from the bottom of my waterheater PE50T9A

Turn off the electric and drain the tank. Completely remove the exit valve that is leaking and clean up the threads on the valve and in the hole. Get some plumbers dope and dope up the fitting threads and the threads in the hole and then reattach the exit valve. As a real precaution you may consider taking the plastic valve to the hardware store and getting a replacement one. Also dope that one up good.

SOURCE: just purchaced a 99 jamboree with an atwood G6a-8e

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.

SOURCE: Have a GE GG40T6A gas hot water tank. Leaking

12 year old water heater is getting near the end.
Some tanks last 20 years, but that's the exception.
To find exact age of your brand water heater:
http://waterheatertimer.org/pdf/WaterHeaterSerialNumberDecoder.pdf

Leaking TP valve:
1) Lift TP lever and gently lower back into position to see if that stops leak.
Occasionally something gets stuck in the valve.
2) Sometimes water heater temperature gets turned up because heater is not producing as much hot water as before, and higher temps cause TP to release pressure because of overheating.
Dial temperature down to 120 degrees.
http://waterheatertimer.org/How-to-adjust-water-heater-temperature.html

3) If steps above don't fix problem, replace TP valve >> TP valves have 125 or 150 degrees rating >>> older tank shouldn't be running above 125 because higher temps cause more pressure on tank, so thermostat should be lower than 125 degrees TP rating.
Buy replacement TP at any hardware store + a roll of teflon tape to seal pipe threads.
Turn gas control to pilot ... this will keep pilot lit but burner will not fire.
Let water cool, and then drain some water out of tank.
If TP valve is on side of tank, then open drain on side of tank and drain water until it is lower than valve level. Open bathtub spigot to let air into line.
http://waterheatertimer.org/Water-heater-will-not-drain.html
Be careful around water that is higher than 120 degrees F >> you can get burned quickly >> apply cold water to any burn.
Use pipe wrench and unscrew TP valve counterclock-wise.
Install new TP and put teflon tape on threads.
Re-fill tank completely and open tub valve on hot side until water is running >> then turn gas control back to original position.
Do not fire up any water heater before tank is completely full of water or this could damage tank.

How to change out copper piping from release valve


If the release valve referred to is the pressure release valve, then a water leak out the attached vent pipe is an indication that the valve is failing. To change the valve, the water must be allowed to cool (turn off AC power or gas) and the water level inside the tank must be lowered (drained) to below the level of the pressure relief valve. Once this is accomplished the vent pipe is unscrewed from the relief valve and the pressure relief valve is unscrewed from the water tank. A new pressure relief valve with a sealant on the threads, is then screwed and tightened into place with the outlet port facing downward. The vent pipe is attached to the new valve and the tank refilled with water. A hot water facet must be opened to allow air to exit while filling. Upon becoming full (water will begin to flow from facet), turn off the facet and restore AC power or gas, therefore allowing the water heater to heat up. When the first hot water is utilized there may be some air expelled from the facet.

Can a pressure relief valve cause hot water to run slowly?


The real question is 'How old is the water heater?'... over time, particularly in areas with hard water, sediment builds up in the water heater. Particularly electric models. typically a TPV (temperature/pressure relief valve) won't cause the symptoms you describe, but mineral deposits around the inlet tube (internal) could, by restricting the flow of water into the water heater.

A TPV is designed to prevent over pressurization which could cause the tank to rupture. I have priced new water heaters as low as $308.00 for a gas powered 40 gallon unit with a 3yr warranty. If you have good soldering (sweat fitting) skills, these are relatively easy to replace yourself. Whether electric or gas, make CERTAIN you shut off the heat source before attempting a replacement.

The water is out flow.After the system runs. It is keep dripping a while then stop. It can be filled up that bucket a day


The water heater is equipped with safety device called a pressure relief valve. This valve is designed to open automatically when water pressure inside the tank becomes too great.

The relief valve should have a lever on the top. Lift it / push down on it briefly and it will allow water in the tank to flow through it (and out the pipe into the bucket). By allowing water to flow, will clear any debris caught between the seat and seal that may be causing the leak. If the valve continues to leak after doing this, the valve should be replaced. In most areas, this type of work is required to be performed by a licensed / qualified plumber.

Good luck!

What should I do about a small leak on the side of my water heater?


What is the warranty on this tank?
Warranties covered failed tank.

Does the tank wall have a leak?
If the tank is leaking on top around inlet pipes, or leak is coming out of weld around TP valve, then water heater must be replaced.

Sweeting from top of heater


Water on top of gas heater can be caused by poor venting, or inadequate combustion.
Make sure water is not coming up from under tank top, indicating tank leak requiring tank replacement.
Have a plumber look at problem to make sure home is not filling with deadly, odorless CO gas.
Inspect pipes that they are not corroded and covered with condensate.
Check that roof cap is in place.
Let heater fire and burn for a few moments so the fire is going good, and then light match just outside the draft hood on top of heater. Blow out match and see if smoke draws immediately into vent and upward.

You posted question under propane gas heater.
Propane is heavier and air, and this type gas water heater should not be installed in basement (below grade) since gas leak can fill basement with explosive gas.
Water leak does not cause gas leak, so water leak is separate problem.
Recommended for propane safety: install gas detector close to floor near gas water heater
Regular Natural Gas heater, install gas detector higher on wall since NG is lighter than air and will rise.

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.
