Bobrick 824-550 – Frequently Asked Questions

1) What does the Bobrick 824-550 bottom housing assembly actually include?
The 824-550 is the complete bottom half of a SureFlo automatic soap dispenser: the ABS plastic bottom housing plus the soap bottle itself. The housing carries the PC board, the motor that drives the gear pump, and the gear pump housing. On the outside you get a portion control knob, a flush button for cleaning and maintenance, a fiber optic cable connector, and a power port. So a failed pump or board is replaced as one assembly rather than piece by piece.
2) Which Bobrick soap dispenser does the 824-550 housing assembly fit?
It is the replacement bottom housing for the Bobrick B-824 SureFlo counter mounted automatic liquid soap dispenser. That is the only dispenser model it is specified for, so if the unit under your counter is a different Bobrick series, this is not the part.
3) My SureFlo dispenser pumps weak or not at all. Is the bottom housing the part I need?
If the pump motor is dead, the gear pump is failed, or the board is not responding, yes, those all live inside the 824-550 bottom housing and it replaces them as one unit. Before you order it, try the flush button on the housing, which is there for system cleaning and clears a line that has gummed up with dried soap. Also check the portion control knob setting, since a short dose reads as a weak pump. A dispenser that never senses a hand at all points at the fiber optic side rather than at this assembly.
4) Will the 824-550 work with a foam soap dispenser?
No. The 824-550 is built around a gear pump and bottle for liquid hand soap, and it is specified for the B-824 liquid SureFlo dispenser. A foam unit meters air and soap differently and needs its own housing. Confirm the dispenser you are servicing is the liquid model before ordering.
5) How much soap does the bottle on the Bobrick 824-550 hold, and what is it made of?
The bottle holds 34 fluid ounces and is translucent, shatter-resistant polyethylene. Translucent matters on a counter mounted unit: housekeeping can eyeball the level from under the counter without pulling the bottle, which is why these get spec'd in high traffic restrooms where refill rounds are on a schedule.
6) Can I adjust how much soap the B-824 dispenses per activation?
Yes, and the control is on this bottom housing. The portion control knob on the 824-550 sets the dose, so a facility running high traffic restrooms can dial the shot down to cut soap consumption, or up if users are double-activating. Replacing the housing gives you a fresh knob, so re-set your dose after installing rather than assuming it comes matched to the old unit.
7) Does the 824-550 assembly mount above or below the counter?
Below. The bottom housing attaches to the bottom of the soap bottle and the whole assembly sits under the deck on a B-824 counter mounted dispenser, with the spout and sensor eye above. That means a swap is done from inside the cabinet, and you do not disturb the counter top or the escutcheon.
8) How does the sensor connect to the 824-550 bottom housing?
Through fiber optic cable. The housing has a dedicated connector for the fiber optic cables plus a power port, so the under-counter assembly links to the above-deck sensing head optically rather than by running a sensor wire. When you swap the housing, both the fiber optic cables and the power lead have to come off the old one and land on the new one.
9) Is the Bobrick 824-550 housing OK in a wet under-sink cabinet?
The bottom housing is water resistant ABS plastic, which is what you want in a cabinet that sees splash and the occasional supply line drip. Water resistant is not submersible, so a housing sitting in standing water from a leaking trap will still fail. Fix the leak, then fit the assembly.
