Question about Water Water Heaters

1 Answer

It's leaking at the point where the hot water pipe leads out of the heater.

I've turned off the water (and gas) supply, have been draining it for hours and it's still leaking at the same rate! At this point I'm just trying to keep the water under control and off the floor. Help??

Turn off gas to the heater close water supply drain the water out of heater.Remove pilot tube assembly remove thermocouple/or thermopile assembly disconnect gas at the union and remove from valve. Use wrench that fits the hex shaped nut that holds the aquastat and water heater in the tapping. Usually the wrench size is 3/4" or 7/8" depending on the unit.

Put pipe dope on the male thread of the valve and keep it off the aquastat bulb, and rethread into the tapping.

Replace the ilot assembly being sure it was not damaged when it was remover if it was damaged replace it. replace the thermocouple/powerpile assembly replace the gas piping from the valve being sure to use pipe dope on the fittings and tighten them enough so they do not leak. Do not use teflon tape because it could get into the gas valve and cause problems.Test the gas piping for leaking do a tight test on the meter if possible or test with testing fluid and look for bubbles or use a gas leak detector that sniffs for gas and beeps when it detects a leak

Fill the water heater up with cold water and check to be sure there are no leaks at the thread where the valve is threaded into the tapping. Open a hot water faucet and be sure the heater is full of water.

Light the pilot and turn the gas on set to the temp that is best suited to you..

Water meter keeps running. When I turn off the water supply to the hot water tank the needle on the water meter stops, does that mean that I have a leak in the hot water pipe coming out of tge tank.


Yes you have a leak on hot pipe or TP overflow tube.
Put ear against pipe to listen for sound of running water.
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html#listen
If TP valve goes into drain line, check if water is running down TP overflow tube.
Check each faucet for leaks.
If pipes are under slab, put ear against each faucet to determine which faucet is closest to broken pipe.

Gas ignites flame but water is not getting hot


You have gas water heater with working burner.
But not getting hot water at faucet?

1) Bad faucet cartridge. Test for crossover. Copy following link:
http://waterheatertimer.org/Crossover.html


2) Is there hot water inside the tank? Open drain valve and check for hot water.

3) Drips and leaks: Turn off all taps and put ear against pipe and listen for water leak.
Water leak can run all the hot out of tank.

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.

    Slight water leak from plastic drain fitting on rheem fury 40 gal gas water heater


    You can try to crack it open and get a little piece of crud out of there, I'm sure that is all it is, Just get a tray or something to catch the water, It should stop it, If it gets worse, turn the water off to the heater, then open the valve and hope the bigger piece of crud comes out. It is about all you can do, other than drain the whole thing and take the valve apart and replace the rubber in it. Check it out, Hope this helps.

    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.

    Water heater heats water, but not long enough or sometimes not hot enough. The hot water runs out too fast, does not provide hot water continually


    The first thing I would do is turn up temp control on gas valve.Control is located on front of gas valve at the bottom front of heater.They usually have a indicator dial on front with an arrow pointing direction.Turn dial to higher setting when burner is not on and this should turn burner on and provide hotter water. The control is normally turned clockwise to increase temperature.If control is already turned all the way up then water heater may need to be replaced.Depending on water quality in your area heater may have a large amount of mineral build up and it may not be capable of producing enough or hot enough water. If this the case all I can suggest is to try to drain tank and flush some of the deposits out. If you have installation manual it will give you instructions on how to do this. If not see if you have working shut off valve on cold water line ,if it works shut it off and connect drain hose to drain valve on bottom right side of gas valve. Put hose to floor drain or sump basin if you have one. Turn control knob on top of gas valve from on to pilot,this will leave pilot light on but prevent burner from working while draining. Open drain valve ,flow rate may be slow or not at all. Open hot water side of some faucet to provide air to help draining. You may try opening water supply valve to heater a few times to aid in draining. If you can get it to drain,shut drain valve off when done,turn cold water supply back on and shut off hot water outlet. Then when tank is full open hot water vavle to bleed air out of heater and piping. Turn control knob on top of gas valve back to on position. This should bring burner back on .It will take about 1/2 hour to heat. If you can't get it to drain or this doesn't help you might consider getting a new 40 gallon heater. Hope this helps. Thanks

    Water Heater Replacement


    1) After shutting off the water and gas or power supply to the tank, connect a hose to the drain valve at the bottom of the tank, open the valve, and run it to a nearby drain or outdoors. Use two wrenches to unscrew the inlet and outlet fittings from the top of the tank. 2) For a gas water heater, shut off the gas inlet valve and use two wrenches to disconnect the union or flare fitting between the gas supply pipe and the inlet valve. Also remove the flue hat that expels gasses into the flue at the top of the tank. 3) After removing the old unit, set the new one in place with the controls and burner accessible. Allow at least 6 inches of clearance around its perimeter, and keep it away from flammable materials. Use a level to check it for plumb; shim the base with pieces of asphalt shingles or plastic wedges. 4) Wrap the threads of the heat trap fittings with pipe-wrap tape, and screw the fittings into the water heater (blue into the cold water inlet and red into the hotwater outlet). Be sure the arrows marked on the fittings point in the direction of water flow. 5) Install new flexible connectors on the water inlet and outlet pipes. If there is no shutoff valve on the cold water side, install one before connecting the water heater. After all connections are complete, open the shutoff valve to fill the tank. While it is filling, open several hot water faucets in the house to bleed off air in the pipes. 6) Assemble the gas pipes as shown. Spread pipe dope on the threads, and screw together the parts, tightening them with one pipe wrench on the pipe and another on the fitting. Follow the manufacturer's instructions for connecting the unit with gas supply tubing. After turning on the gas, test all connections by brushing soapy water on them and watching for bubbles.
