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


If the water in the toilet tank is warmer than the rest of the cold water in the house you could have a toilet tempering valve, they come with integral
check valves . If the check valves fail you have your crossover, If you find where this device is close the hot water feed to the toilet tempering valve,, if it has one.[IMG]

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


This has to be the longest thread on this board.
Please have an ending soon; I'm running out of monitor ink.

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


I finally took some photos of the hot water pipe in the adjacent basement, after I got the key to the basement from one of our condo trustees, and was going to post them. But now I'm wondering whether my thread is too long (especially after bob22's post). I'm not the kind that likes to hog attention.

In any case, the plumber is supposed to drop by this coming Tuesday.

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


I am still going with the dip tube.
Some thing that could have been check early on to insure that it is or is not in place.
I have seen longer postings... Bob's line is really funny if one thinks about monitor ink, just what is monitor ink?

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


Okay, I'm going to post the hot pipe photos. Like last time I posted photos, I'm attaching white stickies so that you can easily note the pipe I'm showing:

1) This is were the hot pipe enters the adjacent basement from my basement:



2) Hot water pipe goes up the ceiling to my condo unit on the 3rd floor (and maybe to the unit of the neighbor on the 3rd floor who shares plumbing with me):



3) This is the same hot pipe starting to go to my neighbor's water heater:



4) Same hot water pipe makes a turn, heading to my neighbor's water heater:



5) Hot water pipe enters my neighbor's water heater:



6) The other part of the hot water pipe goes to yet another basement:

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


Now I want to post photos of what I consider a "mystery" pipe.

1) Cold water pipes from my basement's water heaters and boilers and the cold water pipes from my neighbors' water heaters and boilers in the adjacent basement link up with this pipe (but I've not included photos of the linkage points of those pipes). This pipe has one end in a storage cage in my neighbor's adjacent basement. See below:



2) So starting at the end point it comes out of the cage here:



3) Then it continues on its way:



4) It continues:



5) It makes a turn then ends at the Main shutoff for the whole building:

Why is this pipe a mystery? You would expect to see a main cold water pipe to supply every boiler, water heater, and apartment unit in the building.


The only "mystery pipe" is the hot water pipe FROM your water heater that crosses to the next basement and connects to ANYTHING other than the riser pipe to your apartment.



Now you're saying your hot water pipe connects to your neighbor's water heater AND crosses into yet another basement. This makes no sense. Hopefully your plumber can sort this out, I strongly you get access to all the basements when the plumber comes so no stone will be left unturned.

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


LawnGuy,

What I quickly discovered, as I was taking the photos I presented in my previous posts yesterday, was that they would be a rough draft, just to give the basic layout.

I knew I would have to go back to fill in the gaps because following these pipes is not easy, especially if one is not a plumber. Keep in mind I have to use a flashlight because the basement is quite dark, and the few light bulbs don't really do justice. I'm also trying to take notes as I go along.

Just to be sure: I'm looking to see what (if anything) is connected to the hot pipe, right?

What if I discover that the cold pipe is somehow connected to the cold pipe, would this be what we mean by "crossed pipes?"

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


I think a drawing, like a map, would be easier to follow than sequential photos. You could then show all the various tributaries etc and indicate which are cold and hot.

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


Hi bob22,

How's your monitor ink holding up as a result of my endless thread?

My problem is that my computer/graphics skills are zilch. I have no idea how I could post a drawing here.

But with hindsight, a drawing would have been more helpful than photos. I agree with you.

It's not like being there. Your plumber knows there is a cross-connection it's only a matter of finding it. That requires access to anywhere it could be.

Right, the hot pipe from your water heater.

No. The "crossed pipes" or "cross connection" referred to here is the source of your cold water coming from your hot water taps preventing you from getting hot water from your hot water heater. Its a connection between your hot water supply line and some cold water supply line.



A cold pipe, especially in a basement filled with boilers, water heaters, apartment risers, will branch off many many times. Makes sense, you gotta get the cold water to everything.



But once your gas (which you pay for for your use) water heater heats YOUR water, it should go only to your apartment and not branch off to other basements, apartments, or other water heaters.



As I said, be sure to secure access to all the basements for your plumber to access.

Hi LawnGuy,

In a previous post I stated:

What if I discover that the cold pipe is somehow connected to the cold pipe, would this be what we mean by "crossed pipes?"

I meant to state:

What if I discover that the cold pipe is somehow connected to the HOT pipe, would this be what we mean by "crossed pipes?"

Does this change your answer?

No. We've already established that there is a cross connect. You turn your water heater hot or cold supply valve off, yet you still get water from your hot taps.



If you found a cold water pipe connected to your hot water pipe, that would be a cross connect.

Draw it on paper and take a picture of it with your cell phone or camera.
