SOURCE: Dip Tube

You may want to check the heating elements first. Where I live there is a lot of lime in the water that can coat the elements.

Does an Intertherm water heater model HSE 30F 240S have a dip tube? Cold water comes n on the side of the tank not on top or bottom.


How to Repair or Replace Defective Water Heater Dip Tubes

www.familyhandyman.com > Skills > Plumbing
The role of the dip tube is to direct incoming cold replacement water to the bottom of the tank for heating. While it warms, the dense, cold water stays naturally segregated from the warmer, lighter water floating on top. The water for faucets and appliances comes from the hot layer on top.

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

My reliance natural gas water heater overheats causing scalding water to come out of my faucets. I have had authorized service companies come out three times to replace and retrofit different controls and...


Information below is for tank-type electric or gas heater only.

There is a condition called stacking.
This might apply to your water heater or not.
Having authorized service people to your house 3 times suggests more complicated mix of problems.

Stacking is caused when there are repeated short draws of hot water.
As you know, each time any hot water is drawn out of faucet, cold water immediately enters bottom of tank through the dip tube. The dip tube is connected to cold water inlet and runs to bottom of tank.
So all cold water enters bottom of tank close to the gas water heater thermostat.
See illustration of dip tube, that also shows copper thermostat sticking into tank that is connected to gas valve.
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html#flushelectric

Let's say your water heater if fully heated and burner is off.
A short draw of hot water causes cold water to enter tank.
Another short draw. And then another short draw, each draw happens close to same time as other draws.
Water at top of tank is plenty hot, but bursts of cold water get near thermostat and cause thermostat to turn on burner.
Burner heats water and more hot water rises to top of tank. Water at top of tank becomes overheated each time stacking occurs.

Again, a stacking situation may not be the cause of your problem.
However, remember if single-handled faucet is opened straight upward, then that draws both hot and cold water. And cold water immediately enters tank.
Only when the single-handled faucet is lifted with the handle all the way to the right, does it draw only cold water. Even so, some single-handled faucets have bleed-over between hot and cold sides, so hot water is drawn anyway.

Another possibility is that the dip tube ends at or near thermostat, instead of going all the way to bottom of tank. The dip tube should go straight down from cold water inlet, but dip tubes are made of plastic, and some self-cleaning tanks have a curved dip tube or dip tube with perforations that create currents designed to stir sediments off bottom of tank (although this is not proven to be effective deterrent to sediment formation).

Also take advantage of fixya phone service.
For a price, expert speaks with you over phone while you work on water heater or any do-it-yourself project.
Fixya is always less expensive than a service call.

The nipple on the inflow line of my water heater is corroded.


Hello,The nipple/dip tube will come out as one piece so the tube will be needed also.You can make a new dip tube by FLARING a piece of 5/8"copper at one end and use a BRASS 3/4" stock nipple as an OEM replacement.Factory replacement will be hard to find.Good luck!

Water heater heats but not to same temperature


Try shutting off the gas, shut off the water, and drain the tank to remove any sediment that may interfere with heat transfer from the burner. If that doesn't do it, check the dip tube to make sure it is still intact. The dip tube directs incoming cold water to the bottom of the tank and the hot water is tapped from the top of the tank. If neither of those turn out to be the problem, check the thermo-couple. Since a gas water heater typically survives about 6-9 years, you may be better off just replacing it.
