Looking for push button timer shower rough in

[Plumber69]

Shower rough with a push button that only stays on for say 5 minutes. Do they exsist

I ran into a timed shower shutoff in Germany. It used tokens.

NO! There would not be enough demand for one, (in fact you might be the only buyer), to make it worth designing and setting up a production line.

You could probably cobble something together that would work, but it would probably lack plumbing approvals and a UL listing, making it somewhat of a mute point. Something like maybe a boiler zone valve controlled by a timer using low-voltage controls. You'd need an access panel to provide maintenance, and some shower valves do not work properly if you 'cap' the shower arm. Trying to control both the hot and cold feeds could lead to an unsafe situation where they both didn't operate at the same time and you either got all hot or all cold, neither of which is particularly good. A zone valve might work better than say solenoids, because it would close slower...otherwise, you'd also have to deal with potential water hammer.

There is more than one that build a timer into the showerhead. Google "shower timer".

That is the WORST way to do it. That would create a "cross connection" between the hot and cold lines, because with no water flowing the user would NOT turn off the hot and cold valves, and then you would be coming here to ask why the hot and cold water lines change temperature.

Maybe I worded this wrong. It's not a button. But you push it and shower runs for a certain amount of time. Then you have to push it again. It's for a ice rink. There's 40 showers. Vandel proof shower heads to. People are leaving the water running. I know they exsist. But I don't know what they r called.

There are self closing valves, but I have never heard of one that would run for 5 minutes before turning off.

You're looking for a metered shower valve. Just like a metered faucet.

You could use a solenoid valve with a timer. Similar to what is used in a dishwasher. There are process timers that are designed to do similar type things.

I haven't seen one, but I wonder if someone makes a motion sensing (or IR) controlled valve such that it would only run when someone was standing there? It wouldn't be a timer per se, but would prevent someone from leaving things running. I know they make vanity faucets like that...haven't seen one for a shower.

Kinda sucks if you haven't finished rinsing and the water shuts off - AND your out of tokens.

It might be better to design a push on and push off shower valve.

I think the point is to avoid somebody turning on 40 showers and leaving... like pressing all of the elevator buttons but with more negative impact.

You can set an irrigation valve to run for 5 minutes, so it is do able. If you only had one valve you would need back flow preventers in the hot and cold water lines or you could have a cross flow when the timer closes the solenoid valve.

Having worked in a large airport - I can tell you that's why we use those automatic faucets that shut off just as you barely get a splash of water on your hands.

BTW - modern public-use elevators have a "load weighing anti-nuisance" feature. You can't push all the call buttons at the same time unless the cab is full of people. http://www.mceinc.com/products/specs/section_9.pdf
