I am a Senior Citizen also . I hope this guy gets hot water before I am in the nursing home.

If the dip tube is not there then the new in coming cold water will go strait to the hot out point and then to a faucet that is open.


Been there seen it and fixed the dip tube and that challenge was fixed.


Why is it that people look for the most complex answer to a very simple challenge?
Reminds me of any government department, let us add layers of BS to fix a simple pot hole in the street.

Re: New water heater only sending hot water for a short while


Akpsdvan,

It's amazing how with Internet communication it's very easy to be misunderstood.

I did not post that diagram to suggest that people like you on this forum will learn something from it.

Rather, I was trying to say that for me, that diagram is what made me get a better understanding of how a water heater works.

I appreciated the feedback that I got from people but it only went so far, most likely because some of us are very slow learners (I'm definitely in this group).

I therefore figured I would post the link to that diagram so that if there are other people out there who are like me, trying to solve a water heater issue but with no clue how it works, they might benefit from the diagram.

The diagram is also an opportunity for experienced hands like you, if you're interested, to see how you might explain things differently to a newbie so that he/she understands more quickly what the problem is.


Learning is a never-ending process!

That's all. And thanks for your feedback!

Re: New water heater only sending hot water for a short while


Hi Alan,

Here are the results so far of the test you suggested (they all were done on the kitchen faucet):

1) 1/30/2019 at 11:18pm:
It took 30 seconds for the water to turn hot and 60 seconds later it turned cold.
No valves were shut.

2) 1/31/2019 at 8:55am:
It took 30 seconds for the water to turn hot and 60 seconds later it turned cold.
No valves were shut.

3) 1/31/2019 at 8:42pm:
It took 30 seconds for the water to turn hot and 20 seconds later it turned cold.
The valve for the hot water at the water heater was shut.

4) 2/1/2019 at 8:38am:
It took 30 seconds for the water to turn hot and 15 seconds later it turned cold.
The valve for the hot water and the valve for the cold water at the water heater were both shut.

Do some of these tests with one of the valves above your water closed and with all of those valves open.

We want to find out whether your water heater is really not contributing to the mix.

Note: If you turn off one (any one) of the valves on the pipes going to your water heater and water (any temperature) keeps coming out of your hot faucets then there is definitely some kind of cross connection.

Then your hot water is not supplied from the new water.


Once again I ask, Are you sure that is your heater?

Re: New water heater only sending hot water for a short while


Colbyt,

Thanks for responding.

All I can tell you is that my column or section of the building has only 3 condo owners. All the water heaters are accounted for.

But maybe there's something I do not know. I know that the other owners have already replaced their water heaters. Mine was the last one to be replaced.

I don't know what else to say or do.

There's an old adage that visiting relatives and fish begin to smell after about 3 days. OMG, no wonder that plumber won't come back.
Sorry stripe. Some days I just can't help myself.

Re: New water heater only sending hot water for a short while


a new test, if you have access to the others water heaters, turn off their valve one at a time and check if you still have hot water, you may get water from another bad water heater!

Re: New water heater only sending hot water for a short while


Just had a thought...

Is there a small tank water heater under your sink/sinks or tucked away in your condo?

Re: New water heater only sending hot water for a short while


carmusic,

Are you referring to the hot water valves for the water heaters that me neighbors own?

Also, does this in any way mean that the problem could be different from the crossed pipe possibility? Or is it the same problem?

Re: New water heater only sending hot water for a short while


Have you yet drawn a diagram of the hot pipe from your water heater to where that pipe disappears into the ceiling (in the next basement)? Making a note of any tee along the way and where that branch goes to or comes from? Also making a note of any valves along the way and valves in any branches that you find.

Really, there are not supposed to be any branches along that hot pipe so every such branch you find needs to be explained.

Thanks, Allan.

I have not drawn a diagram for the hot pipe. I will do that as soon as I get a chance. I'm especially thankful for your pointing out what I should be looking out for.

Re: New water heater only sending hot water for a short while


A couple of pages ago I think I suggested drawing a diagram.
Perhaps people can speculate a bit more about what the situation is in reality.

Re: New water heater only sending hot water for a short while


I hear you, Bob.

I need to, once again, get access to the adjacent basement from one of the condo trustees. Once I get it I'll be able to draw the diagram.

Bear with me.

Thanks.
