If it is DSI ignition, there is thermostat and ECO behind that little foam pad with letters on it "Therm", and "ECO", that may need to be adjusted, or replaced. As far as adjustment goes, you want to make sure disc is making good contact with tank surface.I must ask though, are you using city water hook-up, or on board pump to pressure system? As well, have you tried draining water heater and re-filling just to see if that helps?

Easy way to replace it


Replacing a water heater is no very difficult if you follow the steps.
1. If it is electric turn of the breaker and check to be sure it is the right breaker. If it is gas turn off the valve close to the water heater.
2. Turn off both the hot water and cold water valves
3. Drain all water out of the heater.
4. Disconnect the electric wiring if electric and if gas disconnect the gas line.
5. Disconnect both water lines which may have to be cut depending on how they are connected.
6. Now you can remove the water heater and discard.
7. Place new heater where old one was removed and reconnect both water lines and be sure you have a new pressure valve installed on the water heater.
8. At this point you can turn on water and check for leaks. you should also open a hot water faucet to purge the air out.
9. If no leaks go ahead and hook up the electric or gas lines and if gas is used turn it on and check for leaks using a leak detector or a spray bottle of soapy water and look for bubbles. If no leaks you can go ahead and light the heater according to its instructions.
10. If electric is used turn it on.
11. Take a long hot shower.

You should be able to control hot water temperature by adjusting the thermostats. Either or both may have failed, causing heating to increase to the maximum. The "spitting" is caused by boiling water. Likewise, the pressure relief valve is operating as it should resulting in the overflow you observe. You need to get your heater serviced immediately!!

Noisy water pipes when neighbours use water


Install air chamber to cushion sudden-stop of flowing water.
Water flow coming to sudden stop is called water hammer, and will bang pipes, but also loosen plumbing joints, causing leaks.
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html#bang
http://waterheatertimer.org/images/Flow-rates-water-hammer-600.jpg

Air chamber has to be vertical, and about 18" long, with cap on top.
By code each Hot and Cold line at each tap will have air chamber located behind the wall. So there are two air chambers at each tap.

In your case, you can probably add air chamber to your Hot and Cold lines and solve problem for both dwellings.

Water hammer is caused because water does not compress like air.
So when long column of water suddenly stops... the whole pipe-full of water comes to sudden halt... and that water could weigh 1-1/2 pounds ... and just like a hammer head moving, the weight of water bangs the pipes to dissipate energy, causing noise.

Installed a tankless gas hot water heater a few months ago, and ever since then when ever I turn on the hotwater, I get pockets of air coming out of the faucet. There are no leaks in the water lines, but...


1) Never, ever install tankless water heater, unless your wallet is 2" thick and you enjoy nuisance problems and recommended continual maintenance.
2) Add in-line air vent.
http://waterheatertimer.org/images/Air-vent-added-to-return-22.jpg
3) Look for check valve along the line. Look for mixing valve, pressure regulating valve, etc.
4) If you have recirculation system, remove cross-over check valve and see if problem is located there.
5) Contact Rheem. 800-432-8373 They will want model number, serial number, and name of installer. And might recommend contacting installer or plumber.
6) Increase water flow. Check water flow requirement of tankless (.5 gallons per minute activation) with actual flow at faucet.
7) Clean water filter at tankless unit.
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf
8) Crossover at single-handled faucet.
http://waterheatertimer.org/Crossover.html
9) Fix all leaking faucets indoor and outdoor so no air is being sucked in.
10) Bad TP valve on water heater sucking in air each time water pressure pulls on the valve?

How long does it take to reheat water when gas bottle runs out and then you switch to new bottle ?


water getting hot should be almost instant... it may take a minute to move the cold out of the pipes.
is your heater ignighting?
if not then you might have a small amount of air in the gas line when you changed the bottle.
you will need to bleed the line...

with the gas turned on, loosen the gas connection to the unit and let the air out until you smell gas.
tighten the connection, snug, do not over tighten.
wait about 5 minutes for the gas to dissipate before attempting to light the unit.
during this time, you can use a little soap water on the connection you loosened to make sure it is not leaking.

now go turn on your faucets, let the water run for a minute and make sure you get hot water.

if no hot water, then you might have something else wrong. you will need to let us know the error code and what the unit is doing

Water leaking from drain port.


Something easier is to buy a cap for it. You can get one at any home store (same size as a hose). Twist on and done!

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.

Air escaping from hot water faucet


It sounds like you are getting air in the system. Generally the only way this would happen is if the pump is sucking air. The water level may be very low in the well. This is of concern also because the pump is water lubricated (if it is a submersable) and will sustain damge quickly if run dry.

Hot water heater


Absolutely no hot water indicates the top element or thermostat on the heater. Check to make sure that you have 240 volts on the top two terminals of the top thermostat. If you do then check the top element for voltage. It should also read 240 volts between the two screws. If you have 240 volts there shut off the power, drain the heater to a point below the top element and change the top element. When the element is installed turn your WATER back on and let the air bleed out of several hot faucets in the house. When the faucets stop spitting air you can turn them off. Check for leaks around the element. If you have no leaks turn the power back on the the heater and replace the covers.

That should get you 'back in hot water' in two hours.
