Posted by on

1 Answer

Tanks are marked with Hot and Cold.
1) If water connections are on top of tank, look for red marking or word HOT that shows where hot water pipe connects. Look for blue marking or word COLD that shows cold water connection.
2) If water connections are on side of tank, cold water connects to bottom one, and hot connects to top.

3) If hot and cold are reversed, the tank will not work.
Pipes on top of tank: cold water enters tank and is sent to bottom of tank in a long tube called the dip tube. This means the cold is on the bottom since hot water rises to the top. The hot water exits top of tank.
Pipes on side of tank: You want cold water to enter bottom, so hot water naturally rises to the top outlet.

How and where does the water go in


The cold water enters the top, but the water is not released into tank at the top. The cold water goes through a "dip tube" This takes the cold water to the bottom of the tank. If you dip tube fails, or breaks, your faucet temperature will slowly drop as you use hot water (vs giving you 60% of tank at full temperature before temperature starts dropping) In normal operation, the cold water is released near bottom of tank, the hot water rises to top, and comes out of the top of the tank.

Were is cold water inlet and hot water outel on model 71-40d b


Cold inlet and hot outlet are marked on top of water heater.
Usually there is a letter or word embossed into the metal top.

If tank is connected, then turn on hot water tap for a few moment and feel which pipe is hot.

Cold water enters bottom of tank through dip tube located on cold side. If hot and cold are reversed, the water heater will not perform as expected.

DOES WATER IN GO ON TOP OR BOTTOM OF HEATER


1) Low-boy water heater, cold water connects to lower inlet pipe and hot to upper outlet pipe.
Cold enters bottom of heater and then hot water rises to top where it leaves tank.

2) With larger water heaters both hot and cold connections are on top of tank, but the cold water goes to the bottom through the dip tube.

If pipes are reversed, the water heater will not work.

I just bought a Jayco trailer with an Atwood 6 gallon water heater which works on both electric and gas. I was able to locate the bypass valve and made sure hot water was in the tank, however I only get...


Check your by-pass again. Cold water enters bottom fitting/line, and hot comes out the top fitting/line. Any valve in between should be closed, and any valve going in at bottom should be open, as well as open at top. There are a few different by-pass set-ups, so without knowing which one you have, this should guide you somewhat.
If you can describe what you see there, I can probably guide you through it.

Running out of hot water after 10-15 minutes. already changed the bottom element and theromstat and still missing hot hot??


Is the upper element working?
The cold water comes in at the top inlet and there is a tube inside the water heater which takes the water to the bottom. If this tube breaks off the cold water will mix with the hot water on the top and you'll have less hot water. You can take it out and inspect or replace it.

I have hot water for a minute then it goes to warm. I took off the 2 wires on each element and I have 15 ohms on the top and 5.5 on the bottom. Is my bottom element bad?


Sounds like bottom element may be bad but usually reads open circuit if bad. Also tan k would run about 8 gallons hot water then go cold. lots of warm water usually means bad dip tube.
Check if tank is hot at bottom element when not used for a while. If bottom element is still cold then bad element.
If bottom element is hot - (all water in tank is hot then you have a bad "dip tube" This is allowing incoming cold water to mix with outgoing hot water. The dip tube is usually A part of the cold water nipple or B located under the cold water inlet nipple.

Not enough hot water to complete shower. Noticed


If it is a new water heater it might be that the water supplies are crossed. The cold water should be installed on the right hand side of the tank or on the bottom if your tank hooks up on the side. If its an older water heater the dip tube may have broken off. This is a tube that runs from the top of your water heater on the cold side to the lower portion of the tank.It puts the cold water in the bottom of the heater which pushes the hot water to the top.To change the dip tube out you must disconnect the cold water supply from the 3/4 inch nipple at the top of the tank. Then with a pipe wrench unscrew the nipple from the tank it will have the remainder of the tube on it.You can get a replacement dip tube at a plumming supply. Installation is opposite of removal. If this is your problem I suggest you get a new water heater .Usually its caused from minnerals in the water or buy two dissimiler metals being connected together in the water piping system causing corrosion Your water heater will probably fail in the near future.

Hot water comes out cold side for few seconds and gets cold, no hot from hot side, only cold


Make sure that the water pipes for the cold water coming in and the hot water going out are connected to the correct positions on the water heater. If the connections get reversed, the water that is supposed to be hot will be drawn from the bottom of the tank and will not be as hot as it should be. The cold water input goes to the bottom of the tank. The hot water out comes from the top of the tank.

No water coming out of carver cascade water heater


is the cold side hooked to the cold side if not you will be feeding the unit backwars making it to where the cold is just comming across the top of the tank, check the dip tube also, this makes the cold water go to the bottom and push the hot out of its outlet,, how many faucets are involved, if just one might want to check the cartridge to make sure it is working properly
