Tornado Bladder 8 Gallon 19215

Genuine Tornado OEM 8-gallon bladder (part# 19215) for self-contained carpet extractors. The bladder is the flexible solution reservoir that sits inside the tank housing and collapses as the pump draws cleaning solution out of it. Because it is a wet, flexing component under constant pressure cycling, it is one of the parts on these machines that genuinely wears out rather than simply breaking.

How to tell which bladder your machine takes

This is the 8-gallon bladder. Its 12-gallon counterpart is part# 19264, and the two are different components rather than the same item under two numbers — one will not serve in place of the other. The capacity badge on the machine is not a reliable guide on an older unit: the Series B through Series E parts books list both the 8-gallon and the 12-gallon bladder across the Marathon 800 and Marathon 1200 machines, and only the current books narrow to one. On a Series F Marathon 800 this 8-gallon bladder is the current part. If your machine is any earlier series, call us with the serial number and we will check the book for your machine before anything ships.

Symptoms of a failing bladder

Solution loss with no visible leak at the hoses or fittings is the classic sign — the solution is escaping inside the tank housing rather than onto the floor. Others are a machine that will not hold prime, a pump that cycles or runs dry with solution still apparently in the tank, and visible splitting, hardening or perishing at the folds when you pull the bladder out. Mineral scale and hot water both shorten bladder life, so a machine run on hard water or at temperature will typically need one sooner.

Replacement notes

Drain and flush the solution side before you start, and inspect the fitting and its seal while the bladder is out — a tired seal at the outlet will reproduce the same symptoms on a brand-new bladder. Check the inside of the tank housing for sharp edges or debris that could have caused the original failure.

Frequently Asked Questions

What does the 8-gallon bladder (part# 19215) do?

It is the flexible solution reservoir inside the tank housing. Cleaning solution is held in the bladder and the bladder collapses as the pump draws from it, which keeps the solution separated from the recovery side of the machine.

How do I know if the 8-gallon bladder (part# 19215) needs replacing?

Losing solution with no visible leak at the hoses or fittings is the usual sign, because the solution is escaping inside the tank housing. A machine that will not hold prime, a pump cycling or running dry with solution apparently still in the tank, or visible splitting and hardening at the folds all point the same way.

Is the 8-gallon bladder (part# 19215) the same as the 12-gallon bladder 19264?

No — they are genuinely different components and are not interchangeable. Note that the Series B through Series E parts books list both numbers across the Marathon 800 and Marathon 1200 machines, so on an older machine the right number comes from the book for your series rather than from the capacity on the badge. Call 763-535-0770 with your serial number if you are unsure.
