    have you tried tightening it? Was it installed professionally or diy? Is there a short metal pipe with a nut at both ends in between the house plumbing and the hot water heater?

As joe explained tape or pipe dope would be recomended also there should be a seal inside the ends of the short pipe. make sure that seal is seating squarely on the pipe as to make the proper seal it may behoove you to actually take it back loose and visually inspect the rubber seal inside the nut to make sure it is not damaged or defective.

Make sure to use pipe dope(compound) or teflon tape on the threads. If you use the tape make sure to wrap the tape in the direction of the threads. Don't over do it with the tape 5 or 6 wraps should be fine. I prefer pipe dope myself....Joe

Water heater leaking from the top


if its leaking from the top it is possible that it just needs tightening but it is probably that the tank is failing. but to check out the first possibility turn off the water and drain off the pressure if you do not have 2 valves . one on each line you will have to drain the system. then remove the leaking side. in fact remove both sides apply pipe compound or teflon tape and retighten and reconnect all unions .if that solves the problem good if not its time to replace the tank

There is water leaking out of the top of the water heater


OK I am going to go over the things that could bel leaking. first on top I assume that you have no pipes leaking down that you can see. If so repair them first,

Now looking at the top of the heater at the point where the pipes go into the tank. if it is leaking there the heater is bad and you are going to have to replace it.

Heaters for the passed 10 to 15 years have used a foam injected insulation so the leak that pops in the side wall will make the water seek the eazy way out.. So a mid line tank leak may infact show up at the top.

Now loo real colse at the nipples at where the water is coming out on top and dry it with a rad. I dont want you replacing a heater when its the nipples. So look real close. yo want to see the water come UP around to the nipples not down from the nippples.

Have a great day adn best of luck I hope that this was a help to you

Replace cathode tube


If you are wanting to replace the magnezium anode rod you need to shut off the water to your heater and open a valve on the hot side to relieve pressure. The rod or whats left of it is removed from the top of the heater. I'm not sure but I think it's 1 1/8 inch hex nut. You can use a socket or pipe wrench to remove it. Turn it counterclockwise to remove.
You can replace it with standard magnezium rod to extend tank life or if you are haveing odor problems especeilly on the hot side you can get a aluminum rod to help with that. Generally if you are getting sulphur in your water it will smell like rotten eggs. Before you install new rod you should wrap the threads several times. Tighten it up good, close the valve you opened and turn water back on to heater. Check for leaks and bleed air out of hot water lines. Hope this helps you. Thanks

My reliance sta-kleen 502 is leaking. The water is dripping on top of the pilot light, extinguishing the flame . Please advise me with step by step instructions to diagnose and attempt fix this myself....


If you have a leaking water heater there is a serious problem.
http://waterheatertimer.org/Water-heater-leaking.html
Page shows how to limp along on a leaking water heater if your water heater needs replacement.

One of three things is causing the water:
1) Loose water connection on top of tank that is dripping down inside tank >> check pipes on top of tank.

2) The vent is clogged or not working correctly causing condensation inside flue pipe.
Condensation water is dripping back down inside tank.
Problem means possible CO poisoning if gas is not venting.
Look at vent pipe to see if joints are corroded.
Use long fireplace match > light match and put into draft hood at top of tank and see if smoke goes up.
Put hand at draft hood opening when water heater turns on to see if vent gas enters home.
Do same test when furnace turns on to see if furnace vent is pushing back into water heater.
Does water heater vent inside same pipe as furnace? You may need to set up separate vent for water heater if furnace gasses are pushing back into home.
Check furnace vent for obstructions.
Look at vent stack top of home to see if hood is in place.
Check if bird nest is built inside warm vent pipe.
Improper flue is top priority for getting fixed so vent gasses properly escape home.
You may have to call a plumber.
Professional plumbing forum:
http://www.thetankatwaterheaterrescue.com/forums/forum3/

3) Your water heater is rusted out.
A rusted tank has to be replaced.
It cannot be repaired.
However, before replacing tank, you do not want a tank failure where tank ruptures and water runs inside home until water is shut off.
This will cause major damage.
Protect yourself first.
Turn off water valve above tank.
Move gas knob to 'pilot' so burner is not heating water.
Open tub spout on hot side to relieve pressure on tank so it will not rupture.

Now you're protected.
Link above shows how to limp along on failed tank until you can replace heater.

You need a new gas water heater from Lowes or Home Depot
Look at label on side of you tank for gallons and btu's of your water heater.
Measure height to flue pipe so you get same height water heater, so pipes don't have to be changed.
You need a pipe wrench and teflon tape which will be wrapped on each pipe thread when pipes are reassembled.

Step1) Drain water heater using valve at bottom of tank.
http://waterheatertimer.org/Water-heater-will-not-drain.html

2) Turn off gas valve going into heater.
When gas valve is perpendicular to gas line, then gas is off.
Dissemble gas line to water heater.

3) Disconnect flue pipe and support flue pipe with wire so it doesn't not fall down. Flue pipe joints should be held together at each joint with 3 screws.

4) Turn off water. Shut off valve is on COLD side.
Disconnect water pipes.

5) Move old water heater out of way.

6) Set new water heater in place. Put water heater in drip pan.

7) Connect water pipes >> cold goes to side marked cold.
Hot to hot.
Buy new flexible water connector pipes at home center for easy installation of water pipes.

8) Connect gas line exactly as it was connected before.
Home center sells flexible gas line connector for easy installation of gas line.
To test for gas leak after installation, mix liquid soap with water and put around gas line joints to see if there are bubbles.
Natural gas has less pressure than water lines, so gas pipes are easy to seal with ordinary wrench.

9) install TP pipe that runs to floor. Use old one off old heater.

10) Fill tank completely with water until water is coming out of tub spout.

11) Turn on gas, and light pilot as shown in manual.
New gas heater sometimes have small water leak when first fired up, so ignore a bit of water.

12) Save water heater manual like it is gold, and read everything in manual.

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.

I have a 21v40-7 rheemglas waterheater that is leaking from the line where the blue cap and the white water heater meets why is this happening?


If you see water at the top of the water heater you should take a rag and dry everything well, you should be able to see where the leak is from, if it leaks from the metal "housing" up you probably need a new water heater

One thing you will want to check is see if the cold water pipe on this heater is installed on the side or the top of the water heater. A Whirlpool Mobile Home Electric water heater should have the cold water pipe on the side near the bottom of the heater.
If it is not installed on the side of the water heater this can cause you to run out fast.
If the water pipes are installed correctly try contacting the manufacturer at 1-877-817-6750 and they can advise you.
