I'm still getting used to taking nice showers without rushing like the world is about to end. It feels really good. :smile:

I found this video interesting and useful and want to share it with others:

Four Water Heater Tanks Cut Open - Lessons to Learn

I never drained my old water heater. God knows how it looked like inside.

Without going back and reading, have you concluded how/who opened that valve?
My theory would be the plumber as when changing a water heater it would be normal to close all pipes connected to it. Once replaced you go back and open all valves and in this case he forgot that one was closed from the start. Somewhat honest mistake because no one could have guess how this was all connected.

Just my thinking.

Hi Bud,

I don't think the plumber opened the valve. Why? He used the building's Main to install my water heater. In other words, he shut off water to the whole building, then he installed the valve above the hot water outlet and the other valve, above the cold water inlet.

Also, the valve that was denying me hot water is located in the adjacent basement. I was with him when he went to that basement. All he did when he got there was to shut the Main.

I think that valve was always open and my old water heater simply managed to hide the problem. I'm not a plumber but this is what I think happened. Maybe it was more powerful than the new heater? Maybe it operated under higher temperatures, even when on low settings?

Re: New water heater only sending hot water for a short while
 
Thanks, I'm just one of the many curious who have been following. But I'll add, when a plumber opens any pipe they will usually shut off all valves leading to the work they are doing to avoid draining the entire system and because it's very difficult to impossible to solder a pipe while water is draining out of it. It also slows them down because a trickle of water can continue for an annoying length of time. It is also doubtful your old water heater would have overcome this plumbing mistake as the cold was feeding the supply (the hot outlet) before it mixed with the hot water in the tank.

Also, the mistake would have occurred after he was done when he would have turned all valves back on.

Just speculation.

I was with him and saw him shut off the Main only. That's the only valve I saw him touch in that basement that also had the valve that was denying me hot water.

He shut the Main so that he could install the 2 valves above my water heater. The location of the valve that was denying me hot water is at a totally different area from the Main, even though the two vales are in the same basement. And you cannot see it easily, given the storage bins, water heaters, furnaces and numerous other pipes in the place. It's actually like a maze.

When I showed him the trouble valve I could tell from his face that he had never seen it before (unless he's a great actor). The only valve he seemed aware of was the Main.

With the old heater sometimes it took a bit of time to get hot water.

What I want to see what kind of gas bills I get from this month onwards (the new water heater was installed on Feb. 22). Even though the AO Smith I bought is most likely much more efficient than the Allcraft that I had, the gas bills may tell me something. We'll see. I'll let you guys know.

Re: New water heater only sending hot water for a short while
 
Your plumber would only have needed to turn off valve #4 (the one in your hot pipe on your side of the wall) and the cold inlet, to keep all the water from falling down from upstairs and stop the flows enough to solder the new pipes together with when he installed your new heater.

Didn't you say that some other plumber did work in the next basement at or about the same time as your new water heater was installed/? Maybe that plumber opened and closed valves somewhat haphazardly to bring about the problem at or about the same time as your new water heater was installed.

Hi Allan,

The only other plumber who did work in my basement during anywhere close to my water heater installation was this same plumber that installed my water heater.

He installed the water heater for my neighbor on the first floor, several months earlier. But he would not have had any reason to shut off the valve that denied me hot water (in the adjacent basement).

Why? Because my neighbor on the first floor and the neighbor on the second floor have pipes that take a totally different route when compared to my pipes and those of my adjacent neighbor on the 3rd floor where our condo units are located.

Also, I even doubt whether he needed to shut the building's Main when he was installing the first floor water heater, since I think my neighbor on the first floor and the neighbor on the second floor, have a working shutoff valve for their units in my basement.

Having discovered the problem valve (the valve that denied me hot water), it's now clear why my condo unit's shutoff valve in my basement did not work.

I don't know whether all this makes sense from the way I've explained it.

Hi Folks,

Just got my latest gas bill and sharing it in case anyone is interested.

To recap, I got my water heater inspected on February 22 (last month). This was also the day when I solved my water heater problem by shutting off a valve in the adjacent basement of my condo building.

The current bill runs covers February 21 to March 22 and it's for $21.70.

I called my gas company to check what the bill was for the same time last year. It was $78.87. And the year before that it was $61.80.

Re: New water heater only sending hot water for a short while
 
Now the question is, is that difference due to a more efficient new water heater or due to other building units benefiting from the crossed pipes? If other units have been benefiting from the crossed pipes then their months use should have gone up correspondingly. Now, the utility probably can't tell you what the other bill are but maybe they could compare theirs as they did yours and say whether they went up or not.

Or you could ask those neighbors.

Re: New water heater only sending hot water for a short while
 
Seems obvious to me:

1. It worked but the original water heater had a dripping valve that appeared "to fragile to fix."
2. A plumber showed up and installed a new water heater.
3. The customer no longer got consistent hot water. Therefore the problem is the plumber or the hot water heater.
4. The "HOT" pipe on the water heater remained hot when the customer would run out of hot water in the shower or the kitchen sink. Therefore, the hot water heater was working and the plumber had caused the problem.

Glad it got fixed.

When one compares utility bills it is best to compare the average of 2-3 cycles. The meters are read on a 4 week cycle but the weather doesn't always follow such a predictable pattern. Meter readers also make judgement calls when reading the dials on a mechanical meter. Days in the billing cycle can also vary by 1-3 days and the cost per day is a better number to compare than the total billing.

Re: New water heater only sending hot water for a short while
 
You have to look at the previous month bill as well. Many utilities do not read meters monthly, and every other bill is estimated. If the last bill was over estimated, the present bill would correct that. IIRC the OP also heats with gas. Is there also a gas range? Gas clothes dryer? Either way, 21 bucks is a welcome surprise.
