The eyewashes with the integral drain are quite nice and work well. But you have to insist they're plumbed to drain - which seems like a no-brainer to me. Dumping out onto the floor sounds like an omission in design or an oversight in construction.

If memory serves, if you disconnect the tail piece altogether and just allow the water to drain into the drain pan and overflow into a bucket, that might work. Alternatively, you could disconnect the tail piece and have a hole cut into the bottom of the drain pan. When it's folded up into the wall (and architects love that nice clean look), you'll see the drain pan hole, but at least you won't have to go through all sorts of gyrations to collect the drain water from inside the wall.

Are there no options to connect them up to drain, as they are designed?

I would love to hear any responses to this as well as I am having this type installed with my remodel.

Thanks,

Another question from this weekČ??s lab inspections:

We have a 2004 Science building with eyewashes built into the wall (similar to the design found at https://urldefense.proofpoint.com/v2/url?u=http-3A__www.eyewashdirect.com_Bradley-2DS19294HB-2DBarrier-2DFree-2DEyewash-2Dw-2DTailpiece-2Dp_s19294hb.htm&d=BQIGaQ&c=lb62iw4YL4RFalcE2hQUQealT9-RXrryqt9KZX2qu2s&r=meWM1Buqv4IQ27AlK1OJRjcQl09S1Zta6YXKalY_Io0&m=EVo3tbkOvis_mZs4Ub41BYWHRcWLULcsLsexjSt5GMA&s=xM9PVi18EaMDhCtVyzxv7LI9sjPW1BE7hK0Sp0SB0fA&e= ). When the eyewash is activated, the water flows back into the drain in the wall and then expelled onto the floor under the eyewash in an ever-growing puddle. My immediate concern is that the water comes out of a pipe which is between 6 and 10 inches from the floor. (There is a floor drain in the area of the pipe which serves the safety shower as well.) The imedidate problem is that location of the drain pipe is low enough that collecting water from it when flushing the eyewash is difficult; we currently use a secondary containment b!
in tipped under the pipe in such a way that weČ??re able to collect about 1/3 of the capacity of th!

e bin.

I wonder if anyone on the list has developed a modification to this design that is reasonably priced (weČ??re talking about 20 units with this condition) that would allow for collection of the flush water in a way that is convenient for the person conducting the flushing? This design also presents challenges for the emergency eyewash use case, but thatČ??s not my primary motivation in considering modifications; IČ??m more concerned with enabling more frequent flushing of the eyewashes.

Thanks for any experience with this question.
