Hot water heater has a leak somewhere but not at top where water hoses connected

The insulation gets soaked and leaks out. No leak up top or at tp valve. Where else could it be? It is only about 3-4 yr old.

    It's strange that the heater would be leaking but not from the valves. I found a hole in mine near the bottom of the tank, but it's at least 15 years old, whereas yours is only 4 years old. I'm not sure how to fix yours, but I think I'll call a water heater installation service to have a new one installed. https://rapidfirstplumbing.com/plumbers-...

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: Hot water heater leaking at the top valvue

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

SOURCE: leaking tp valve

It is time for a New Water Heater.....But there are a few steps you can take to "TROUBLE SHOOT" the situation. There is a Drain Valve at the Bottom of the Water Heater. You may have a build up of ....gunk...at the bottom of your water heater, if you have a floor drain in a basement or some way for the water to drain, than you can carefully loosen the drain at the bottom of the tank to FLUSH the tank.....The other option will still reqiure draining the tank and replacing the heating element.. My best Solution is to make sure the bottom of your Mobile home is Insulated Properly From the Wind and Elements. Even Bails of Hay stacked around your Foundation Can be VERY Effective.....MOSTLY THOUGH I THINK IF YOU DRAIN THE TANK AND REPLACE THE HEATING ELEMENT, your problem will be over, With proper Insulation under the Mobile. This has worked for me a few times..... Hope it helps.....Joe

SOURCE: Hot water tank leak

drain valve must have already been leaking, that's why someone put the cap on. It's ok to cap the drain but never the pressure/temp relief. If the water is coming out of the drain (not around it) you could either replace the cap or the drain valve to stop the leak - otherwise it's time for a new water heater.

I have a 2000, 2619 trail manor and the water heater TP valve leaks when I run the heater. I'm not sure if the TP valve is defective or if it's the temp control unit itself. Any ideas?

Too much pressure on city water input. Use a regulator pressure. or, shut up the city water valve outside open the TP valve and a hot water faucet inside the house and let water drain out until it stop running out. Close TP valve, hot water faucet and then open city water valve. That will create and air cushion on top of the TP valve inside the tank and then no more leak on TP valve

My anode rod, and dip tube and t& P tube relief gasket is leaking

Copy following link for general troubleshoot:
Then add a comment and let's get the problem solved.
http://waterheatertimer.org/Leaking-water-heater.html

FYI:
Anode rod is either connected to hot-water nipple, or installed in separate port located top of tank. Anode stops water heater tank from rusting.
Dip tube is a plastic tube that is connected to cold water nipple and extends to bottom of tank so cold water always enters tank bottom.
TP valve is brass safety valve that is screwed into a port located on top of tank, or located on side of tank, and will release water when pressure or temperature exceed rating of TP.

I have a Rheem B33325 hot water tank, it is leaking from the pvc pipe that runs down the side of the tank. Help!

Sounds like TP valve is leaking:
http://waterheatertimer.org/Leaking-water-heater.html
http://waterheatertimer.org/How-to-replace-TP-valve.html

Do not cap off TP valve.
Raise lever and gently lower back down to see if TP will turn off
Replace TP valve.

If problem persists, re-post question with specifics about your tank: such as electric, or gas, and if unit has a blower on top, and if gas control valve is electronic or has a dial.

606 electoric little or not hot water

Reliance 606 240Volt water heater.
This water heater is fully repairable by homeowner

You have some hot water so that says upper element is good.
It also says electricity to water heater is good.
Also your reset button is not tripped. water heater is not overheating.
And covers and insulation are installed properly on water heater.
Water pipes are not clogged, and tank is not leaking water on floor.

Here are the suspects:
1) Leaking faucet or TP valve is running hot water continuously. Check for leaks.
http://waterheatertimer.org/How-to-replace-TP-valve.html

2) Loose wire/ bad wire: remove covers and check for loose wire and signs of high heat and burning.
Also do full troubleshoot:
http://waterheatertimer.org/How-to-troubleshoot-electric-water-heater.html

3) Bad lower element, possibly due to sediment build up: Test element.
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html

I have a Rheem 40 gallon hot water heater which is about 2 years old. The drain valve drips a bit while the hot water heater is heating up the water and then stops once the water is heated up. What is the...

When you say drain valve, do you mean TP valve?
Two different things: -drain valve and -TP valve

-Drain valve is located near bottom of tank and has hose thread on end.
-TP valve is brass and is located on side of tank tank near top on , and has a pipe that runs down within 6" of floor, or pipe goes into a drain pipe. DO NOT CAP OFF TP VALVE because this is safety outlet that prevents extremely hot water from rupturing tank.
http://waterheatertimer.org/Leaking-water-heater.html

1) If drain valve located near bottom of tank is leaking, it can be capped with a garden hose cap from hardware store-home center. Thread cap on end of drain valve.

2) If TP valve is leaking.
a)Turn down thermostats on water heater
http://waterheatertimer.org/How-to-adjust-water-heater-temperature.html
b)Replace TP valve
http://waterheatertimer.org/How-to-replace-TP-valve.html
c) Install expansion tank on incoming cold water line
Buy expansion tank at hardware-home center-plumbing supply and tee straight out from cold water line and attach expansion tank. About the size of small football.

This event has only been reported once in past 10 years that I have read, and it blew out side of home. Stats for this type event don't exist in insurance company records, so you are safe - just don't cap off TP valve.

WATER IS DRIPPING FROM THE OUTLET VELVE LOCATED ON TOP WATER HEATER.

That sounds like the TP valve is leaking.
http://waterheatertimer.org/Water-heater-leaking.html

1) Leaking TP valve can be caused by defective TP valve
How to replace TP valve:
http://waterheatertimer.org/How-to-replace-TP-valve.html

2) TP valve can also be caused by overheated tank.
Turn down thermostat.
Install expansion tank on incoming cold water line.
Electric heater: thermostat or element may be bad and tank needs troubleshooting
Gas heater: thermostat is connected to gas valve and gas valve may need replacement.

3) First step is replace TP valve and see if that solves problem.

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.

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:
