Hot Water Temperature to a bar area?

[John_187]

I don't see a plumbing forum, so don't where to ask this question besides here.

There is a bar area in a residential community assisted living center. There is no dishwasher, but there is a 3 comp sink. They say no washing will take place there (in spite of their being a 3 comp sink). There is an adjacent building that is connected via a walkway. This adjacent building is served off a totally different hot water system. Typically I would supply 140 F to this bar area because of the 3 comp sink, but they are requesting this be served off a 120 F line serving the residential units. If this bar is to be served off 140 F, it would require a dedicated 140 hot water and return line, lot of extra piping.

Would you think this is acceptable? The local jurisdiction authority gave a vague response and didn't if 120 F was a problem.

Thank for any feedback.

I vote to bring the plumbing engineering forum back.

Unless they are serving no food and serving their drinks in disposable containers, they will be washing something. Typically the Health Code will require 140 to a 3 bowl sink (no matter what they say they are going to do with it). Stick to your guns and supply 140 to the sink.

What you can do is put a small (~30 gal) water heater either under the sink or on the wall near the sink and feed 120 to it and discharge 140 to the sink. I have done this a lot in renovations where there is a small kitchen type use in the middle of a building and no 140 water in the vicinity. Since the sink will be fairly close to the use, minimal if any recirc is required.

Sounds like a tankless water heater under the bar might be an option, maybe fed from the remote 120° source ?
