Do You Need a Second Glasswasher? A Working Landlord’s Take
Saturday at Teal Farm runs 180 covers. Add in the bar trade, the quiz crowd nursing pints all evening, and the football punters who seem physically incapable of using the same glass twice, and my single glasswasher is working flat out from five o’clock until close. Some nights it doesn’t stop. Not once.
That’s when the question stops being theoretical.

The Single Machine Problem
Most pub glasswashers run a two-minute cycle. In theory, that’s thirty racks an hour. In practice, you’re loading, unloading, waiting for the element to recover heat, dealing with the rinse aid alarm, and trying to keep service moving at the same time. You’re getting closer to twenty racks on a good shift.
One machine is fine for a quiet Tuesday. It is not fine for a packed Friday when your bar staff are three deep and the glass return is overflowing. The moment your machine goes down — and it will go down, because mechanical things do — you’re washing by hand or you’re closing early.
I’ve done both. Neither is acceptable.
The Backup Case
A second glasswasher doesn’t have to run all week. It sits ready. On Monday through Thursday it might do one rack at the end of the night. On Friday and Saturday it earns its place on the floor.
Think of it like a second fryer in the kitchen. You don’t run it for a Wednesday lunchtime. You run it because Saturday service would collapse without it.
The calculation is straightforward:
- Average glass cost: £1.50–£3.00 per unit
- One bad Friday: 40–60 broken or lost glasses when staff are scrambling
- That’s £60–£180 in glass replacement alone, before you count the drinks you couldn’t serve because there were no clean pints
A decent commercial glasswasher pays for itself faster than most operators expect. And if your current machine fails mid-service, the backup becomes your only machine. That’s not a backup anymore — that’s your entire operation.
What to Buy
For a second unit, you don’t need your flagship machine. You need reliable, compact, and fast. The [Buffalo Countertop Glasswasher](https://amzn.to/4ukKRuU does exactly what it says. Single-phase power, 500mm footprint, two-minute cycle. It sits on the bar, it doesn’t argue, and it keeps glasses moving when the main unit is maxed out.
It’s the machine I’d put in as a backup without hesitation.
The Drain Pump Rule
Before you buy any glasswasher — backup unit or otherwise — check whether your installation point has a gravity drain or whether you need a built-in drain pump. This catches operators every time. A machine without a drain pump installed below the drain outlet level either won’t drain, drains slowly, or backs up into the machine and causes hygiene failures you cannot explain to an EHO inspector. Specify the drain pump. Always. Non-negotiable.
The Simple Decision Framework
Ask yourself three questions:
- Do you have a service where one machine can’t keep up? If yes, you need a second unit.
- What does one hour of washed-glass downtime cost you in lost sales? Do that maths once and the equipment cost looks different.
- Can you afford a single point of failure in your glass operation? On a Saturday night? No. You cannot.
Fifteen years running pubs tells me the operators who argue against a second glasswasher are the same ones who’ve never been behind the bar on a broken machine at nine o’clock on a Friday.
