    Is there water in the pilot tube? Is it one of the new low nox water heaters with the flash guard? I need more information please.

  • Glenn Snow May 11, 2010

    If this electric, the breaker to the water heater may be tripped off, or the cold water feed valve to the w/h may have been inadvertantly left closed?? or the pipe repair person may have routed the cold water pipe around the water heater.... stuff like this needs to be checked then we can id the problem better.

Repair a cold water leak at the bottom of my water heater


Hi -

If your water heater is working (ie: making hot water) then most likely your heater isn't leaking. Rather, the leak is coming from the cold water supply and running down the tank where you see it at the bottom of the tank. A working tank that is leaking would produce a leak of hot water - not cold. You should carefully check the cold water piping for a leak, drip or stream of water and make the required repairs.

I have a new Bradford white 40 gallon gas hot water heater. There are no single handle faucets. The hot water fluctuates between hot and cold. When I close both inlet and outlet shut off for the hot water...


Sounds like water leak.
For example, broken pipe... or water running out of TP valve.
That would explain variable hot-and-cold water at tap.
Turn off all taps, and observe if water meter is registering water usage.

Water is leaking from the pipe on the top of the tank (Reliance 606 electric) where the hot water comes out and goes into the house. Likely causes?


If tank is rusted out, then that is caused by depleted anode rod, or tank that is not electrically grounded on hot side pipe.
If pipe nipple is rusted out, then that can be caused by improper connection between copper and galvanized pipes, and caused by non-grounded hot water pipes.

If tank is leaking, replace it.
If nipple is leaking, remove with pipe wrench, apply teflon tape or joint compound on threads, and install new nipple. Replace anode rod if possible. Correct copper-galvanized connections. Add ground wire between hot and cold pipes.

You have 2 problems with several possible causes:
You have 10-year-old electric water heater that was reinstalled after falling down, and doesn't heat the water.
And you have no hot or cold water pressure, and no pipes are leaking.

1) First problem is lack of water pressure throughout house.
Turn on outdoor spigot nearest to water meter.
This spigot will tell you if problem is inside the house or between the house and meter.
If spigot runs full force, then you probably have clogged pipe where water heater connects to main cold line, or the main shut off valve got clogged with sediment that broke off inside the pipe when you were working on water heater.
Open and close shut off valve to see if that helps. Then disassemble pipes and track back the problem. Put pressure gauge on water heater drain valve to watch pressure drop when turning on indoor faucet.
Read following information:
http://waterheatertimer.org/Low-hot-water-pressure.html

Water heater doesn't work:
Test across wires at top of heater to see if you are getting correct voltage:
If tank is receiving correct voltage, then no hot water puts suspicion on upper element or upper thermostat, or both.

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.

    I have a Rheem 40 gal. tank that is leaking water front the top where the vent stack is. It is pouring out. Can it be repaired?


    A leaking water heater cannot be repaired, assuming it's the tank leaking and not nearby water pipe.
    http://waterheatertimer.org/Water-heater-leaking.html

    First thing is to protect your property from catastrophic tank failure where tank ruptures and water runs until it is shut off:
    Tanks are under pressure when they are hot.
    Close cold water shut-off located above tank.
    Turn control knob to 'pilot' so pilot is lit but burner will not turn on.
    Open hot side on tub for few moments to relieve tank pressure.

    Now your property is safe.
    You need a new water heater.
    In mean time, gas water heater makes 41 gallons hot water per hour.
    Shower used 5-9 gallons hot water.
    Bath uses 10-15 gallons hot water.
    You can turn on water heater for short stretches and limp by until you get a new heater.

    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.

    Turned off the hot water to fix a leaking tap. now the tap has no hot or cold water and the hot water tank valve is leaking?


    It sounds like two problems.
    Problem 1) Clog inside faucet or clog inside pipes at faucet
    Remove supply tubes leading to faucet and see if problem is inside pipes or inside faucet.
    My bet is clog inside faucet.

    If you have galvanized pipe that meets copper pipe, this can be trouble spot.
    Article on clogged water pipes at Inspectapedia:
    http://www.inspectapedia.com/water/Water_Pipe_Clog_Repair_Guide.htm

    Article on clogged pipes:
    http://www.waterheaterrescue.com/pages/WHRpages/English/Troubleshooting/Tanklets/backflushing.html

    Problem 2) Water heater leak ... you say tank valve is leaking? Is that cold-water shut-off valve? Or tank drain valve? Or TP valve?

    If cold water shut-off is leaking, then replace shut off.

    If tank drain valve is leaking, then check if plastic valve is cracked. If drain valve is cracked, then replace with a brass valve from Home Depot. If plastic valve breaks off, then use hammer and screwdriver to gently chip out the broken plastic valve. New valve threads need teflon tape to seal pipe. If valve is just dripping, then put garden-hose cap over end of valve and screw down tight.

    If TP valve is leaking, then replace with same temperature and pressure rating.
    New TP valve threads need teflon tape to seal pipe.

    Problem 3) If pressure is low all over house:
    Buy pressure gauge at hardware store that screws onto hose connection.

    Test pressure on outdoor spigot.
    Open faucet and check if pressure drops. This says if problem is inside pipes that enter house.

    Test pressure on water heater drain valve.
    This says if pressure problem is before -or- after water heater.

    If problem is before the water heater, then shut-off valve located on cold water line is suspect.
    If problem is after water heater, it could be in hot water outflow pipe on top of water heater, or a nearby elbow.

    Remove hot water line leading from water heater and check pressure. This says if problem is where hot water leaves tank.
    Read articles above about clogs inside water lines.

    Drain pipe leaking on outside of home from hot water heater,? cause


    You have a safety valve which is made to relieve pressure in the hot water heater in case it overheats. It may have developed a leak. Sometime you can lift up the valve and close it again a few times and it will reseal otherwise replace it. It's on the top of the heater with a small lever. Usually made of brass.

    The elbow is broken and the air from the hot water tank is leaked


    Any exhaust air coming from the gas water heater is potentionally life threating. I would get it fixed. Do you have a CO2 meter close by the water heater? If it is leaking air back into the house that has CO2, after a certain amount the alarm will go off. If you dont have one get one. A must have with gas appliances.
