  • commercial bathrooms and floor drains

    Alameda Ca. Stopped at a new starbucks today. Men's room had no floor drain.
    I don't do any Comm. plumbing. Is the drain the designer's call???
    I can build anything You want , if you draw a picture of it , on the back of a big enough check .

    Where I live it is related to the urinals.

    Urinals that automatically flush (no sensor - flush based on time and/or when the tank develops head) - need a floor drain

    Urinals with manual flush - no floor drain

    Urinals that flush by sensor - no floor drain

      Is it a designers call?
      For the most part,yes.
      I'd like to see more of my customers lean towards them.Unfortunately it's not my money.It's an investment to put in the drain,trap primer and slope the floor for drainage.So they more than likely go without.

          I worked for a couple of months in Oakland on some condos right at the west side of the Caldecott Tunnel up on the hill just north of the freeway. It was a nice project but it was tough finding a decent place to stay in Oakland. I think it retrospect Orinda may have been a better place to stay.

              brings up some questions for me; I'd never run into a trap primer until recently.

              they exist to keep the trap from drying out? or another reason?

              when are they required?

              are they new? or is the requirement new? I've only seen a couple and both in brand new buildings.
              This is my reminder to myself that no good will ever come from discussing politics or religion with anyone, ever.

                  They are there to keep the trap from drying out. Connected to a lav. drain. Often an area will let you put in a hosebibb (vandal protected) under a lav. or in an accessible area to "wet" the trap in my experience.

                  If you're cleaning the floor as you should, seems like the trap would stay primed to me.

                    We use mechanical primers that are activated from a fixture dropping the staic pressure.They also make tailpieces for flushometers that with provide enough water to a trap.Usually a mop is too dry to provide enough water for traps.I have been turned down with the hose bib."What if nobody uses it,how do they know to use it."

                        If you are breaking the concrete near the floor drain, I bet you lunch that you'll be replacing it w/vent and primer.

                        If the concrete around it stays, then you may be ok...I'd almost make the bet regardless though because of no vent.

                            to add to the trap primer discussion.

                            trap primers use to be allowed with a separate shut off valve. no more

                            also they use to have an adjusting screw. we can't use those kind either.

                            truthfully, a trap primer valve is a pain in the butt.

                            i prefer the non mechanical style, such as on a tail piece of a flushometer.

                            unfortunately, not ever application is on a commercial bathroom. lots are on laundry floor drains in residential applications.

                              Do I need professional help? Here in Ca. Safeway is the large grocery chain. I use the bathroom there once in a while. I notice the stainless steel trap primer door is always open
                              and a spray bottle with bathroom cleaner is in there! Tight fit,so this Guy shuts off the full port valve to accommodate spray bottle fit. I remove spray bottle,turn on valve ,use My leatherman tool to lock door. Happens again,I'll remove valve handle. This could get interesting! Told Ya I like Plumin.
