How to Install an Eyewash Station

So you’ve purchased an eyewash station (or stations) and you’ve familiarised yourself with the all-important ANSI Z358.1 regulations - now it’s time for installation. In this guide, we’ll walk you through the basic installation instructions for both wall-mounted and freestanding eye wash stations.

Before installation

First things first: remove the packaging from your new eye wash station and make sure that you have all the necessary components (these should be listed in the manufacturer’s instructions) and that they are not damaged.

You should also thoroughly rinse the unit, both inside and out, making sure to remove any dust, dirt and debris that may have built up during storage.

Finally, while the following instruction can act as a general installation guide, all eyewash stations are different, so be sure to read carefully through the manufacturer’s instructions.

Installing a wall-mounted eyewash station

What you’ll need:

Wall fastener anchors for 3/8” bolts
Bolts and washers (3/8”)
Wall fasteners
Pipe sealant
1 ¼” slip joint P-trap/drain connection

Position the unit on the wall close to drain and supply lines and between 33” and 45” from the floor, in order to comply with the ANSI Z358.1 regulations. Holding the unit steady, mark the wall with the position of the mounting bolt holes. Remove the unit and install the wall fastener anchors where you marked the wall, then fix the unit to the wall using the 3/8” bolts.

Next, connect the tailpiece to the eye wash unit. Install the sanitary drain line and P-trap so that it aligns with the eye wash unit, then connect to the tailpiece.

Finally, connect the supply line with the ball valve on the eye wash station. Open the water supply and test the unit for leaks, making sure that the flow rate is in line with the ANSI regulations.

Installing a freestanding eye wash station

What you’ll need:
Floor fastener anchors
Bolts and washers
Pipe sealant

Position the unit so that there is at least a 9” gap between the left-hand or rear wall and the centre of the drainage bowl, and at least an 11” gap from the right-hand wall. Hold the unit in place and mark the position of the floor mounting holes. Install the floor anchors in the appropriate positions, then use the bolts to fasten the unit to the floor.

Connect the drain line to the 1 ¼” female tee. If not already installed, make sure the drain line is in a position that aligns with the female tee beforehand.

Lastly, connect the water supply line with the ball valve on the eye wash unit. Open the water supply and ensure that the unit discharges water at the ANSI-approved rate and is free from leakages.
