Why does my hot water go hot and cold on my gas hot water service


When water feels cold at tap, check water heater TP valve and drain valve to see if water is hot at top and bottom of heater
Maybe you have bad single-handle faucet cartridge

Another possible cause is bad dip tube

Cold water connection is hot


Did you put hot to hot side? And cold to cold side?
Cold water pipe usually has shut-off valve.

I have a gas Rheem hot water heater.....The flame appears to be on full blast, not just the pilot. I have run no hot water today, so we shouldn't be out of hot water. The water our of the hot faucet...


Sounds like you have cold water entering the hot pipe, or crossover.

(A) Put bucket under water heater overflow pipe, and stand back from scalding water. Gently open and close the TP relief valve on water heater. Check temperature of water to see if heater genuinely has hot water.
It could be the water heater has sediment build-up and is no longer able to heat the water, or the gas thermostat is bad.

http://waterheatertimer.org/How-to-install-gas-water-heater.html

(B) If water heater has hot water, and hot is not getting to faucet, then you have a crossover problem somewhere.
1) This problem can be located at crossover point of a recirculation system, if re-circ check valve has failed.
http://waterheatertimer.org/Water-heater-recirculation-system.html

2) Failure of a single handle faucet cartridge can cause crossover.
Read how to test for crossover:
http://waterheatertimer.org/pdf/Crossover-on-single-handled-faucet.pdf

3) Other causes for crossover are a failed check valve elsewhere in the plumbing system, for example on the pool equipment. Also a failed mixing valve which is usually installed on top of the water heater so that some areas of the house like laundry room receive very hot water, while the kids bathroom receives lower temperature water.

I have replaced my electric water heater and I have checked everything I can think of and I still run out of hot water in 3 minutes. What on earth is the problem.


3 minutes?? does the water run cold then? or just warm?
Is this what the tank you replaced was doing? If so, then you may have: 1 a recirculating pump instant hot water system thats faulty and allowing cold water backflow into hot water piping. 2 A tempering valve that has stuck, allowing cold water into your hot water system.
Or maybe a broken or missing dip tube in your new heater.
If after 3 minutes the water is coming cold out leave that faucet running and go to heater and feel the hot water outlet pipe from the heater. if that pipe is hot then the heater is not the problem. If the hot pipe from the heater is cold the heater is the problem. (Make sure the cold pipe coming into the heater is connected to the Right side marked "cold" !) If there is a tempering valve by the heater: feel the output from the tempering valve, if it is cold and the pipe from the heater to the tempering valve is hot, then the tempering valve is the problem. If all these are OK somewhere in your plumbing system hot and cold may be connected possibly a faucet or showerhead that is shut off at the spout/head, but hot/cold handles are left turned on then cold water can backflow thru hot pipe.

Tankless on demand water heater.


Tankless water heaters normally take a little longer than a regular heater to provide hot water because they have to start and get warmed up. I'm guessing the heater uses a pilot light and that the short amount of hot water when you turn on the tap is hot because when the water is sitting still in the heater the heat from the pilot light is enough to get it hot. The tub faucet will get hot a lot faster than the shower because it lets a lot more water through and empties out the pipes faster than the shower. You could probably speed things up by letting the tub faucet run on completely hot for like 10-15 seconds and then turning on the shower.

Size and installation for instant water heater


Ariston gl4.0 should be fine if used inline with your hot water heater. Used alone it will likely run out when dishwasher is filling and you are using sink.To use your existing hot water for backup: 1 connect existing HOT water line to cold (inlet) on ariston, 2 Then HOT (outlet) from ariston to sink and dw. If you want instant hot water at a sink 10 feet away: use 3/8 pex pipe from ariston to sink, so you only have to run off a cupful or 2 before hot water arrives at sink.
