Question about Water Heaters

Leaking tp valve

If you turn on a hot water faucet in the house with only the hot water shut off, should you get any water? We have never gotten hot water anywhere in the house, only lukewarm, unless the washing machine was on (I wash in cold) It is next to the water heater, If its on, the hot water at the faucets around the house register 120 degrees, otherwise, it rarely gets above lukewarm. Now the tp valve is leaking.

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

Hot water valve leaking how do I take part no.


You will need to turn off the water heater first. Shut off cold water inlet valve to tank. Open the drain at bottom with hose attached to suitable drainage area, hot water will damage plants and grass so if you want to use the water let unit cool off for a few hours or drain down past the valve level. You can open the release on the temp/pressure vale and it will help vent and allow you to know the level. Take a small pipe wrench or large channel lock pliers and remove the drain line pipe connected to the valve body. Open a faucet that is the longest run and wait. The valve can be found at most home centers and are basically all the same with the BTU and pressure rating on the label. Take with you to match length and ratings. Apply Teflon tape or pipe dope on threads to help seal the fitting and tighten up till unit is secure and the opening points down for overflow pipe installation, reseal and tighten. Close off drain and refill with faucet and valve release open, when water starts to run out of valve close and continue filling until all air is bled out. Then relight water heater or turn on power. Check for leaks and test valve for operation. The TP valve should be tested annually for safety.

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 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.

Is my water heater leaking?


You have water leak that you can hear running water.
Could be broken pipe under house.
Could be water running out of tank at TP valve.

Turn off all water taps and put ear against each pipe at tank.
If TP valve is leaking, then replace TP valve.
If pipe is broken under house, then call contractor.

Has Leaking noise very audible on hotwater line but no flood in the house or outside the house, and the water meter records unusually high. Three certified plumbers checked the house but could not find...


First, find out if you have a leak.
Turn off all water faucets inside and outside.
Record water meter register with camera.
Wait several hours.
Record water meter register again, and compare photos.
If you have a leak, contact city water department and report leak so bill can possibly be adjusted.
Ask city water department what they suggest.

If you had certified plumbers look at problem, it would be a guessing game for internet plumber to start listing things.

My guess would be crossover on single-handled faucet that runs the hot water into cold pipe that is filling the swimming pool that is leaking. But you might not have a swimming pool.
http://waterheatertimer.org/Crossover.html

Another guess would be a leaking TP valve that drains directly into a sewer vent line.
But certainly the plumber checked the TP valve.

I have abosch 1600 ps aquastar 4.3 gpm indoor when i turn hot water on it all fires up but no hot water comes out only luke warm water why


Water heater is heating water but only luke warm water arrives at faucet.
Open TP valve and confirm that hot water is available.
If water at TP valve is hot, then problem might be plumbing-related, for example crossover.

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.

Have a GE GG40T6A gas hot water tank. Leaking really bad out of the pressure relief valve. It is a rental property, gas was off to the house (tenants moved out in the night). When the gas company turned...


12 year old water heater is getting near the end.
Some tanks last 20 years, but that's the exception.
To find exact age of your brand water heater:
http://waterheatertimer.org/pdf/WaterHeaterSerialNumberDecoder.pdf

Leaking TP valve:
1) Lift TP lever and gently lower back into position to see if that stops leak.
Occasionally something gets stuck in the valve.
2) Sometimes water heater temperature gets turned up because heater is not producing as much hot water as before, and higher temps cause TP to release pressure because of overheating.
Dial temperature down to 120 degrees.
http://waterheatertimer.org/How-to-adjust-water-heater-temperature.html

3) If steps above don't fix problem, replace TP valve >> TP valves have 125 or 150 degrees rating >>> older tank shouldn't be running above 125 because higher temps cause more pressure on tank, so thermostat should be lower than 125 degrees TP rating.
Buy replacement TP at any hardware store + a roll of teflon tape to seal pipe threads.
Turn gas control to pilot ... this will keep pilot lit but burner will not fire.
Let water cool, and then drain some water out of tank.
If TP valve is on side of tank, then open drain on side of tank and drain water until it is lower than valve level. Open bathtub spigot to let air into line.
http://waterheatertimer.org/Water-heater-will-not-drain.html
Be careful around water that is higher than 120 degrees F >> you can get burned quickly >> apply cold water to any burn.
Use pipe wrench and unscrew TP valve counterclock-wise.
Install new TP and put teflon tape on threads.
Re-fill tank completely and open tub valve on hot side until water is running >> then turn gas control back to original position.
Do not fire up any water heater before tank is completely full of water or this could damage tank.

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.

1 Answer

Tp valve opening and dumping water


Certain water heaters can only handle so much pressure from the main line. There is a pressure controller between your water meter and you house, it's called a pressure regulator. You need to call a plumber to check and see if it needs to be adjusted or even replaced.
