Steady water coming out of drain line

Constant water coming out of the drain line after the saftey relief valve. I already tried to flush the valve out of any debris as the manuel suggested. however the problem continues. my boiler is running at the suggested 12lbs of pressure and tops of about 140f. Under the max temp. Why the constant water discharge?

SOURCE: boiler leak

Hi, it appears you have a defected relief valve. you can try one solution. lift the handle on the relief valve and let some water out. sometimes that can flush out materials thats blocking the stem in the valve. if it's still leaking it must be replace.

If this doesn’t work for you please write back. Thanks,

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: Gas water heater is discharging out the pressure

The water heater is over heating the water, possibly boiling it and causing steam pressure build up. The thermostat is not sensing the temp to shut off the flame. It would be wise to either have a repairman come out or replace the heater. If pressure builds too high and the relief valve cand keep up ,theer could be a rupure of a water lineSoooooooooooo, turn the gas off and git er done.

SOURCE: Too much water draining from Vulcan Electric H/W relief valve.

Dear Julie. Do you have an expansion tank installed? If so it is probably waterlogged. If you come home shower etc. use lots hot water then go to bed or leave the cold water in your tank heats and expands as it heats. In the old days a toilet ballcock valve would relieve this pressure but modern toilets with diaphragm valves wont so the pt valve relieves pressure. Installing an expansion tank on the cold water line near the heater will absorb the extra water & stop the pt valve from activating.

WOULD SOFT WATER HAVE A BAD EFFECT ON THIS MODEL AS IT HAS RUSTY BITS


Hot water heaters are a collector of sediment. The proper care includes flushing out the collected debris through the low side drain faucet. The problem is the faucet is not designed correctly to carry out the needed task. If you are handy... turn off the water and gas or electricity to your water heater. Relieve the water pressure through the temperature/pressure relief valve on the side of the water heater tank. Once pressure is relieved close the valve. Determine if you have a 1/2 inch or a 3/4 inch diameter drain valve hole in the side of the tank where the drain valve is located. The drain valve can be removed with channel lock pliers, an 8 or 10 inch adjustable wrench, or a small 8 to 10 inch pipe wrench. Water will leak out the threaded hole while the valve is out. If everything is closed maybe 2 cups of water will leak out of the hot water tank as you check drain valve thread size. DO NOT take your time checking thread size. After you know the pipe thread size go to the hardware store ( Home Depot, Lowe's etc) purchase a short nipple (1 1/2 to 3 inch depending on available space) and a ball valve (brass) due to the water temperature. You will also need a brass adapter for pipe thread to garden hose thread (male both ends). This adapter goes into the ball valve to allow for the connection of a garden hose. Connect the pipe and valve together using the correct pipe thread sealant and install in place of the original plastic drain valve. Install pipe to hose adapter using thread sealant. With the ball valve in place turn the water back on. Gas or electricity back on. Connect a garden hose to the ball valve. Place the other end of the garden hose in a safe area as hot water and debris will be expelled through the hose. With water on, Gas or Electricity on and the relief valve closed actuate the ball valve to the full open position for approximately 3 seconds then close the valve. Repeat the open and close of the ball valve three times. Observe the debris that emptied out of the garden hose. You may be surprised at what you see. If the water runs clear, disconnect the garden hose the task is completed. You can wait until the following year to repeat the process. Your pipe and valve are now a part of the water heater, they may remain in place. Put the hose away.

Rust in water heater tank


the tank needs flushed out ! heres how. Water heater manufacturers recommend flushing sediment from your storage type water heater periodically.
If your water heater is gas, set the gas valve to "Pilot" to prevent the burners from coming on while you are flushing it. If your heater is electric be sure to turn off the circuit breakers. With an electric water heater, if the water level drops below the heating elements and the thermostat turns the elements on, the heating elements will probably burn out quite rapidly. Connect a garden hose to the drain valve at the bottom of the tank, Close the shut off valve on the cold inlet to the water heater. open the temperature/pressure relief valve at the top of the tank by lifting the lever. Leave the valve open. Open the drain valve at the bottom of the heater allowing the water to flow out through the garden hose. when the water is clear your finished. close pressure relief valve on top of tank and turn water back on.
Open a hot water faucet in your house, and let it run until no air bubbles come out.

Turn the heater back on, and with gas units re-light the pilot light if necessary. good-day !

My pressure relief valve on my boiler is allowing water to pass through constantly.how do i adjust it to stop the water flow? only have about 15 pounds of pressure in system


Even a small amount of crud on the rubber washer/sealer can cause the valve to seep. Some valves can be taken apart and cleaned but it will be better to replace the valve. They can be found on line for around $12 or more. You will have to shut off the water in take valve and drain most of the system unless you have a main line shut off valve so the system wont drain back into the boiler. These valves are usually set at 30PSI.

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.

    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.

    MY GE PRESSURE RELIEF VALVE HAS JUST STARTED LEAKING. WHAT SHOULD I DO ? GE SMART WATER HEATER GELN0705CO3984


    Hello,
    You can buy a replacement relief valve at any hardware or home improvement store. It's real name is a T&P valve or temperature and pressure relief valve. It always has a 3/4" inlet and outlet. It is a very easy procedure to replace. You will need a bucket, teflon pipe thread tape, and a 3/4" x 6" black iron or galvanized pipe nipple. To start the valve replacement, turn off the shuttoff valve on the cold water line. Then open the handle on the relief valve and drain water into the bucket, that is, unless you have a pvc pipe coming off of it into a drain floor, then just drain it without the bucket. Be careful, the water is hot! When the water level gets below the relief valve, it will stop draining. Then remove the pvc pipe, if applicable, and thread in the 6" pipe nipple to use as a leverage tool to remove the valve from the water tank. Turn it counter clockwise to remove. Then put teflon tape on the new valve, going from left to right with the valve threads facing downward. Wrap about 3-4 layers all around the threads. Then twist the new valve into the water tank clockwise and using the pipe nipple tighten by hand until very snug and outlet is facing downward, as before. Remove the pipe nipple and install pvc pipe, if applicable. Leave valve handle open and turn on the cold water until the valve starts spitting, then close the relief valve and let it fill up the tank. If you did it correctly, you are now finished! Good luck!

    We have a fast drip coming from the drain, what does that mean?


    The pressure relief valve is going bad causing water to run out of drain line. They are easy to replace and they are a standard 3/4' threads. Turn power off and drain water down till no water comes out of drain if you lift the lever on the relief valve.
    Lowes or Home Depot will carry a replacement for this heater. The T & P valve is a safety feature that will open if the pressue get's to high due to high heat in heater. With this you would get a blast of hot water running out.
    T & P valve start to go bad they start dripping and evenually can not hold water back. This is a early sign for you to replace before it goes to running out.

    Flooded bathroom from top of unit


    The T&P valve (temperature and pressure) relief valve is suppose to have a 3/4 in drain line threaded into it .This line should have ran to a trapped drain or possibly to the outside of the house. A water heater cannot over fill. To drain your water heater run a garden hose to the outside or to the lowest drain you have nearby.If its still wet be carfull not to get shocked,Attach the garden hose to the drain valve located towards the bottom of the water heater. turn the valve on. If water dosnt come out of the other end of the hose,youll have to see if you can run a peice of wire through the valve into the water heater to get it to drain. This can somtimes be a real problem . I usually leave the water on when i first connect the hose to the drain valve. This allows the water pressure to flush the sedament out of the bottom of the water heater.

    My electric reliance water heater is making a constant noise


    it might be hard water in the heater. the hard water flakes and when your water heater turns on it creates some movement in those hard water flakes and makes a popping and hissing noise then when it comes to temperature it should stop. the temperature and pressure relief valve shouldn't make this noise. but if you stick your finger in the pipe and it is wet then you might have problems some where else. let me know if it is
