SOURCE: Water is either hot or cold - no in between.

I found a way to get warm water in the shower, but I'm not sure it qualifies as a solution. After trying everything else I thought that maybe when I was feathering the faucet in the shower toward the cold side so I would get warm water that at a certain point it blocked the flow on the hot water side enough so that the sensor in the hot water heater sensed there was no demand in the line and it shut the water heater off. To test this, I went to the kitchen and turned the kitchen sink faucet all the way to the hot side and then turned it on so that I got a small flow of water. I waited for the water to get hot to be sure the hot water heater was working. Once it was hot, I left it running to keep demand in the line and then I went to the shower and turned the faucet on. When the water got hot I started feathering the control towards the cold side and soon I had warm water. So I think I'm right in that the sensor in the hot water heater was shutting the water heater off when the demand in the shower was lowered to a certain point when I was trying to adjust the water temp in the shower.

So now I can get warm water, but it means I have to leave the hot water running at another fixture in the house to create a false demand in the system so the hot water heater doesn't shut down. Is there a way to adjust the senor in the hot water heater so that it will stay on when I'm using the shower only, so I don't have to waste water by running another faucet when I want to take a shower?

SOURCE: Water heater ground

run to breaker panel or drive a 8ft ground rod and connect to it the water line is no longer acceptable as the public utility's are using pvc for gas and water now and this is no longer a practice you could use the ground rod that is already installed on your service and use connector , but something you might do well to check is to make sure in the process of installing the plastic pipes the ground going to the panel was not also disrupted if so you will need to install 2 8ft ground rods at least 6 ft apart and daisey chain together with proper size ground wire . # 4 solid for 200 amp and # 6 solid for 100 amp service , I would make sure the panel ground is solid very important for safety ,, let me know if i can further assist

SOURCE: the elbow is broken and the air from the hot water tank is leaked

Any exhaust air coming from the gas water heater is potentionally life threating. I would get it fixed. Do you have a CO2 meter close by the water heater? If it is leaking air back into the house that has CO2, after a certain amount the alarm will go off. If you dont have one get one. A must have with gas appliances.

Hot water heater has hot in tank but dose not come out of hot water line on tank
most electric hot water systems use a heat transfer process where the element is in one tank and the house water is in another
the house water is what is being drawn off when you turn on a tap
there is a regulator valve at the top of the tank with a small lever that you open up to let water in and air out of the system
another point is that there may be a hot/cold mixer on the hot water outlet which limits the temperature of hot water to prevent scalding injuries in the bath and shower or sink
If you have one fitted they are known to malfunction and cut the hot water temperature down as, they mix too much cold water into the hot water pipe.
have a plumber check it out

My hot water to the shower goes cold after 3-4 mins could please help?
a couple of things to check on the side of the hot water system you will see a valve with a small lever
lift that lever until there is a solid stream of water coming from the pipe
that ensures that the heater tank is full
next -if you have a temperature mixer on the hot water pipe out of the tank ( stops scolds in the bath, shower sink) by controlling the temperature mix at the tank
They are known to fail and shut down the hot water supply by adding extra cold water into the system
other than that get a plumber in to fix the fault.

est and replace a high-limit cutoff:
  1. Disconnect power to the heater at the electrical panel and post a sign warning others not to turn it on.
  2. Remove the upper access panel and push the reset button.
  3. Replace the access panel and turn the power back on. If the water is hot, the reset was the problem. If not, you'll need to turn the power off again and reopen the access panel.
  4. Use a multimeter to test the cutoff terminals for continuity. If faulty, replace with an exact replacement part.
Drain a tank:
  1. Shut off power at the electrical panel and post a sign warning others not to turn it on.
  2. Close the cold-water supply valve and open a hot-water faucet somewhere in the house (to speed draining).
  3. Attach a garden hose to the drain valve and run it outside the house.
  4. Open the drain valve and allow all water to drain out.
  5. To refill the tank, close the drain valve tightly and open the cold-water supply valve. Also open a nearby hot-water faucet. When a steady stream of water flows from that faucet, the tank is full and the faucet can be closed.
  6. Once the tank is full, turn the electrical power back on.
Test and replace a relief valve:
  1. Lift the spring lever on the valve to fill a small cup. Check the cup for sediment.
  2. If no water spurts out, or if water continues to drip after the valve is released, replace the valve.
  3. Cut power at the electrical panel and post a sign warning others not to turn it on. Close the cold-water supply valve.
  4. Drain a few gallons of water from the tank.
  5. Unscrew and remove the discharge pipe if used.
  6. Loosen the relief valve with a pipe wrench, then remove the valve by hand.
  7. Apply pipe tape to the threads of the replacement valve and screw it into the tank by hand. Tighten it with a pipe wrench. Screw the discharge pipe (if any) into the valve outlet.
  8. Refill the water heater and restore electrical power.
Replace a drain valve:
  1. Shut off power at the electrical panel and post a sign warning others not to turn it on.
  2. Close the cold-water supply valve and drain the water heater completely (see above).
  3. Unscrew the drain valve with a pipe wrench.
  4. Replace the drain valve with an identical unit wrapping the end with pipe tape.
  5. Refill the tank and restore electricity.

If there is no hot water, first push the reset button on the high-temperature cutoff; test the thermostat and replace if faulty (see below). Test the heating elements and replace if faulty (see below).
If there is not enough hot water, adjust the thermostat settings. As needed, reset, test and replace thermostats and heating elements if faulty.
If the water is too hot, adjust the thermostat settings and reset. Test and replace the thermostat or high-limit cutoff (see below).
An electric water heater is a 240-volt appliance that can deliver a fatal shock. Always turn off power to the heater at the electrical panel 585dc480-4881-44a8-afda-7267c0f3de26.jpgbefore beginning work, and verify that power has been shut off. Make sure others in the house know not to restore electricity prematurely. If you have any doubt as to whether electricity has been turned off, seek professional assistance.

When I run hot water for the tub, it has a brown tint
10 year old homes today usually do not have galvanized pipe. They have copper or pex plastic pipe. These do not rust.
Is rusty water on both hot and cold line, or just hot line?
Just hot line, then check anode rod and flush tank:
http://waterheatertimer.org/Replace-anode-rod.html
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html#flush
Are you on water well? Well casing can get rusted. Water can have minerals. Call local water well service and describe problem in detail.
Are you on city water or mudd district water? Is pipe coming into house made of galvanized? Look inside meter box or look at pipe coming into house. Sometimes the city water line at end of run can get filled with sediments that will discolor water. Have water company flush the city water line.

You have 2 problems with several possible causes:
You have 10-year-old electric water heater that was reinstalled after falling down, and doesn't heat the water.
And you have no hot or cold water pressure, and no pipes are leaking.

1) First problem is lack of water pressure throughout house.
Turn on outdoor spigot nearest to water meter.
This spigot will tell you if problem is inside the house or between the house and meter.
If spigot runs full force, then you probably have clogged pipe where water heater connects to main cold line, or the main shut off valve got clogged with sediment that broke off inside the pipe when you were working on water heater.
Open and close shut off valve to see if that helps. Then disassemble pipes and track back the problem. Put pressure gauge on water heater drain valve to watch pressure drop when turning on indoor faucet.
Read following information:
http://waterheatertimer.org/Low-hot-water-pressure.html

Water heater doesn't work:
Test across wires at top of heater to see if you are getting correct voltage:
If tank is receiving correct voltage, then no hot water puts suspicion on upper element or upper thermostat, or both.

I have a Reliance Sta-Kleen 805 Electric Water Heater that is leaking from the cold valve but the water is coming out hot. How do I repair it?
If I understand correctly you have residential electric water heater, and your shut off valve located above water heater on cold-water line is leaking?

1) Hot water would come out of this valve if it's leaking because water inside tank is hot and under pressure ... also remember, hot water rises so tank is probably heating the water inside the cold line during hours when no hot water is being used.

2) You probably need to replace the valve. But if water is leaking because a pipe is rusted, the valve may be ok, and just the pipe needs to be replaced.
Take a photo of your problem to hardware store or home center.
I used to work in those stores and could help folks get the right parts.

3) Here are some steps for replacing the valve.
Shut off main water source into house. This is usually located underground in same box where meter-reader looks at meter.
Your water heater shut off valve is called a gate valve, and it will be 3/4"
All water heater pipes are 3/4"
You will need two 10-12" pipe wrenches, maybe a new gate valve, maybe a new flex connector, probably short 3/4 pipe pieces, teflon tape for each threaded pipe.
Hardware store or home center can get you the right materials, just take a photo over to hardware store

4) When you get started, turn off water heater circuit breaker for a couple hours so water will cool down. You don't want to get scalded with hot water.
Do NOT drain the tank.
Simply open a bathtub faucet on hot side to release pressure.
When finished, turn on the water, and make sure water is flowing out of tub spout in full stream before turning circuit breaker ON

Rheem small 6 gallon water heater vibration/noise
If the water heater is working fine than I would not worry about the function of the water heater. What the problem may be is that some of your WATER LINES HAVE MOVED, AS THEY WERE NOT SECURED PROPERLY. The sound you may have heard was the Copper or PVC(Plastic) lines just getting back comfortable. I Suggest checking that your water lines are secured about every 3 or 4 feet with the proper ancjhor....Metal for metal pipe, copper for copper pipe, etc. Sometime as in my house, pipes are run through a hole drilled through a stud or a piece of wood, usually when hot water is run through this pipe. You can here an expansion of the water line interacting with the pipe expanding, if the hole in the wood was not drilled big enough......Experience of remodeling a very old house.......Joe
