ᐅ There is no hot water coming through in the shower anymore.

Hello building experts and helpers,

I have a problem in my new condominium and wanted to ask you for advice.

In the bathroom, in the shower, there is an exposed mixing valve that is currently not installed. Two pipe connections come out of the wall—one for hot water and one for cold water. Next to this, there is a washbasin with two pipe connections coming from the wall as well, where the water is mixed directly in the faucet.

The problem: Only a small amount of hot water is coming from the shower’s hot water pipe, while everything is normal at the washbasin. When I turn off the main valve for the shower, the dripping stops; when I turn it back on, hardly any water flows. The cold water pressure is normal both in the shower and at the washbasin. The apartment was empty for about two years before, but I don’t know if the valve was turned off during that time.

All other hot water connections in the apartment, for example in the kitchen, have normal flow.

I hope I have explained my problem clearly enough. How can I get the water flowing properly again?

Thank you very much for your answers.

You seem to have a high tolerance for hardship.
At this pace, you might soon want to buy a season ticket for the public pool just to have warm water...

Sorry, I couldn’t resist that joke...

I hope you get hot water soon... But I would start sending written reminders.
If it’s a rental apartment, you might even consider threatening a rent reduction. You could possibly inquire about the appropriate amount at a consumer protection agency (available in almost every city).

I hope you don’t think I’m trying to fool you, but the problem is as follows:

I have a hot water meter in the bathroom. Next to it, there is a water outlet to the bathtub (no faucet installed), a water outlet to the washbasin, and a shut-off valve.

As I mentioned, I have opened and closed the shut-off valve several times. When I open the shut-off valve, hot water flows from the washbasin at normal pressure.

Problem: No water comes from the bathtub outlet, not even a drop, and the hot water meter doesn’t register any flow... This is also true when the hot water at the washbasin is running. I spoke with the meter reading company, and they want to come and take a look...

I assume this problem cannot be solved by remote diagnosis. The strange thing is that the water meter does not run, and only one water outlet remains dry.

No, I actually assume the following: not only the sink but also the bathtub has a separate hot water meter – and you haven’t found its shut-off valve yet. It might be located under the bathtub, behind an access panel?

The access panel on the bathtub is sealed with silicone. I don’t think anyone would turn off a shut-off valve located behind it, close the panel, and then seal it again. Of course, you can never be completely sure.

It’s also strange that the hot water meter doesn’t register any flow, even though hot water is running at the sink.

Maybe it's possible to track down the plumbing company that originally installed everything (pipe network, sanitary systems, etc.)?

The company does not, but the multi-family house has been maintained for many years by the same plumber. Hopefully, he knows more. He will also be coming by this week.
