If you own a Speakman eye face wash unit - whether it's the platform-operated SE106, the hand-operated SE603, the hand-and-foot-operated SE607, the SE663PO, or the bowl-free SE685 - getting the water flow balanced correctly is essential for both comfort and compliance. Speakman safety showers and eye/face washes are designed to deliver a controlled, even flow across both shroud heads, but over time, or after installation, that flow can become unbalanced. The good news is that every Speakman eye face wash comes with built-in adjustment screws that make flow control adjustment a quick, tool-free (or single-tool) job you can do yourself in a couple of minutes.
The adjustment screws are located on the shrouds themselves, as shown in the diagram above. Each shroud has its own screw, allowing you to independently fine-tune the balance and flow rate of each side. To adjust, simply turn the screw clockwise to reduce flow or counter-clockwise to increase it, making small adjustments and testing the water pattern after each turn. The goal is an even, gentle flow from both shrouds that fully covers the eyes and face without excessive pressure - too strong a flow can cause discomfort or injury during an actual emergency, while too weak a flow won't adequately flush contaminants. This applies whether you're maintaining a bowl-style unit like the SE106 or SE607, or a no-bowl configuration like the SE685.
Regular flow checks are a key part of safety shower and eyewash maintenance, and many workplace safety standards recommend testing weekly to confirm adequate, balanced flow. If you're unsure whether your Speakman SE106, SE603, SE607, SE663PO, or SE685 unit is flowing correctly, a quick visual check against the adjustment screws is the first place to start before assuming a part needs replacing.
