Eyewash Indirect Connection (Again)
Eyewash Indirect Connection (Again)
(OP)
Hello Folks,
For some reason my post back in Aug was deleted. I would like to pose the question again: Is the connection between the bowl drain of an eyewash and the sanitary system supposed to be an indirect connection or can the bowl drain be directly connected to the sanitary system (of course with proper trapping and venting)?
Thanks, Hugh

RE: Eyewash Indirect Connection (Again)
They do make them to indirect to a floor drain also. I have seen these when there is also a safety shower which typically drains to a floor drain. The rationale is why have two drains when one is acceptable.
RE: Eyewash Indirect Connection (Again)
Having said that, in Canada it is acceptable to either directly or indirectly connect an eyewash drain to the sanitary sewer. I've done both.
RE: Eyewash Indirect Connection (Again)
This testing should keep the trap primed.
RE: Eyewash Indirect Connection (Again)
Both ways are acceptable, giving the trap is primed. However, more consideration should be given to what is being discharged into the system, ie. a dedicated acid waste system to protect run off when fixture is in operation.
I only have to design by the IPC, so designing by local jurisdictions is crucial in determining the correct method.

Thanks again for the feedback.

In the event that nothing is downstream, the nozzles on the eyewash are above the flood level rim of the bowl so there would not be any contact between the backed up waste and the potable water.
