Hot water heater leaking at the top valvue

I recently installed a new Whirlpool electric water heater. I noticed the other day that the top valve was spitting out hot water. This is the valve located above the popoff valve.
Is this normal or could there be a problem with the heater or the way it is installed.

    I checked yesterday to find out that the Pop off valve on the side of the water heater is spitting out hot water. I do not have the pop of valve attached to a drain line so the water is draining onto the ground below the water heater. Is it normal for the pop off valve to release pressure and water, or is the pop off valve faulty. Is it possible that the water temperature is set too high?

    Thanks to all that responded. I installed this heater for a lady that couldn't afford to pay to have the work done. Your answers give me piece of mine that she wouldn't have problem in the future because of something I installed improperly. I will hook up a drain line to the TP valve this weekend and hopefully the problem will be resolved.

    after thinking about this the pop off valve should have a pipe connected to it and goes to a drain or to the outside It is highly unlikely that it has a shutoff valve on it( handle)

    please follow the line from the pop off valve to a drain or outside and confirm that it is a drain tube




  • Steve Archer May 11, 2010

    Please clarify

    there is a cold water supply (has shut off valve about 13 inches up from where it goes into top of water heater

    there is a hot water line coming out (feel it its hot)

    and then there is a pop off valve that is seerater

    which one is spitting , how far is it from top of water heater and did you solder any pipes or did you connect the new heater with flex line

    once yu clarify the leak I can help you

I believe the problem you had with the pop off valve is a one time thing since you said you just installed the water h eater

The pop off valve is a pressure relief valve that is activated by build up in the tank from excessive pressure either through too much heat or pressure which works by pressing aginst a spring loaded valve


If you go to the whater heater and look at the valve ther is a handle on it take your hand (stand clear of valve opening) and slowly pull it you will see water start to come out

More than likely a new valve could have had a piece of debris in it or was partially open
re
If the heater was overheating the valve would stay open and you would see extremly hot water rushing out

I do not recommend that you replace the valve unless it continues


Good luck to you

If it is your pop off valve (also known as a temp and pressure valve) it will most likely be due to a over pressure situation, whether it is due to excessive temp, or high street pressure, I'm not sure.  There is also usually a vacuum breaker on the cold side of the hot water tank, this will on occasion spit out a little water, but unless it is defective, it should never be so much as that you would notice a "leak".
Another thing, if it is the T & P Valve, there should be no shut off installed on the piping.  There should be a pipe that terminates with 18" of the floor, and it is not normal for this valve to discharge unless there is a problem with the temp or the pressure inside the tank.
Hope this helps

You need to identify why the Temperature and Pressure Valve is Leaking .
If the valve is defective relace it.
Is the home in question on City Water Service? If so the problem may be a check valve in the system.
Several years ago the Federal Government required water purveyors to install check valves at the water meters. This has created a problem for many homeowners as the water heats up in the water heater the water expands and because of the check valve in the system the water has no where to go.
Go to the following web page and check out thermol expansion.
http://www.watts.com/pro/divisions/watersafety_flowcontrol/learnabout/learnabout_thermexpansion.asp#generalinfo
THe same problem can exist on a well system if a check valve has been installed.
What ever you do DO NOT cap off the T&P valve it is a crucial safety device on the water heater.
I hope this helps!

Easy way to replace it


Replacing a water heater is no very difficult if you follow the steps.
1. If it is electric turn of the breaker and check to be sure it is the right breaker. If it is gas turn off the valve close to the water heater.
2. Turn off both the hot water and cold water valves
3. Drain all water out of the heater.
4. Disconnect the electric wiring if electric and if gas disconnect the gas line.
5. Disconnect both water lines which may have to be cut depending on how they are connected.
6. Now you can remove the water heater and discard.
7. Place new heater where old one was removed and reconnect both water lines and be sure you have a new pressure valve installed on the water heater.
8. At this point you can turn on water and check for leaks. you should also open a hot water faucet to purge the air out.
9. If no leaks go ahead and hook up the electric or gas lines and if gas is used turn it on and check for leaks using a leak detector or a spray bottle of soapy water and look for bubbles. If no leaks you can go ahead and light the heater according to its instructions.
10. If electric is used turn it on.
11. Take a long hot shower.

Hotwater heater new won't heat??


Is water inside tank Hot?
Open TP valve and also open drain valve.
If tank is hot, then you might have plumbing problem caused by bad faucet cartridge or check valve.
http://waterheatertimer.org/Crossover.html

Red reset button is located on upper thermostat.
Test for 120Volt across top two screws on upper thermostat.
You might have a bad upper thermostat.
If electric water heater has some hot water, then upper element is good.
Electrician should enjoy following page full of information.

Are the hot and cold pipes reversed on top of tank?
Usually the cold water line has shut-off valve.
Top of tank is marked H and C

It is leaking out of the top. not out of the hot or cold valves but out of a nut by the cold side.


Your tank is rusted out and needs to be replaced.
Link below is a troubleshoot for leaking water heater.
http://waterheatertimer.org/Leaking-water-heater.html

Protect yourself first:
If your tank is rusted, there is danger of rupture.
My friend welded his leaking tank, but he assumes the risk.
Ruptured tank can cause massive damage and water runs until it is shut off.

Hot water tank is under pressure because hot water expands and pushes against tank wall.
Turn off water to tank.
Turn off power supply:
Electric: turn off circuit breaker.
Gas: rotate knob to pilot so pilot stays lit but burner will not fire. To turn back on, rotate knob to ON.
Open hot side bathtub valve and relieve pressure on tank.

You can limp by with rusted tank by turning water heater on when hot water is needed.
Shower uses 5-9 gallons hot water
Bath uses 12-15 gallon hot water
Ordinary gas heater makes 41 gallons hot water per hour
Ordinary electric heater makes 20 gallons hot water per hour.

I buy water heaters at Lowes, Home Depot, Ace.
Look for scratch and dent models.
Buy drip pan for water heater.
Wrap electric heater totally with insulation except TP valve.
Buy new flexible connectors for water lines.
Offer 15% less than marked price on tank, because the store makes money on additional items.

> Most people can install their own electric heater since you just connect water pipes and electric wire, and it's done. Read link below since there are tips that help you buy and install electric.
> Generally people are nervous about installing gas water heater, so step-by-step instructions are shown on link below. Remember gas line is under less pressure than water line, so if you can install a water pipe, you can install gas line to water heater with crescent wrench, and soapy water to check for leaks.

The temp./pressure valve on top of the heater is leaking. what is the cause and solution.


It is possile that it had apressure fluction for various reasons. It's also possible that valve spring is just getting weak. What i would do first is replace T&P valve and see what happens.These are common 3/4 inch male iron pipe t&p valve available at most hardware stores. First shut off water supply to water heater, then open valve on hot water side of nearest faucet to relieve pressure. Remove old valve by turning counterclockwise. You may need a pipe wrench as they can be pretty tight. Remove old t&p valve and use teflon pipe tape or joint compound on new valve threads. Install new valve and tighten securely. Close faucet previously opened to relieve pressure,then turn water supply valve to water heater. Check for leaks and tighten further if needed. Check valve occasionally for next couple days. If no further leaks from valve then your're in business. Hope this helps. Thanks

We have a reliance 606 50 gallon electric water heater. recently we noticed it has an internal leak. I removed the top and removed some of the insulation. the pipe fittings are dry but when you put water...


I wrote a page on leaking water heaters.
With a checklist.
It sounds like you've done quite a bit already.
The element can leak around the gasket.
The TP valve can leak where it screws into side of tank.
Otherwise a leak on side of tank sounds like the tank is rusted through and needs to be replaced.
http://waterheatertimer.org/Water-heater-leaking.html

You should turn off electricity and water to the tank, and open tub valve on hot side to relieve pressure so the tank will not rupture.
Then you can limp along with a failed water heater by turning the water and electricity on only when hot water is needed.
This will buy you time until a new heater is installed.
A typical electric water heater produces 21 gallons of hot water per hour.
A shower uses 6-9 gallon of hot water, so heater only needs to be turned on 20-30 minutes for a shower, more if the incoming water is very cold.

To economize with your next heater, you might read the following two pages:

My hot water heater is leaking out of long drain pipe


The long drain pipe is the expansion relief overflow, it is too hot. The thermostats are too high. Or the valve is shot. Do you notice the water being too hot to touch? You might want to drop the temp a couple notches. There are thermostats on both gas and electric units. Also, do you have hard water? I have seen hard water build up on the expansion valve and cause it to leak, you could open that up for a second and let out some water to see if it will unclog it. Careful! Hope this helps.
