Tornado Spotter Solution Tank 19490

The Tornado Spotter Solution Tank 19490 is the genuine OEM solution tank for the PS Series professional spotters — the moulded body that holds the clean cleaning solution the pump draws from. Tornado’s dealer catalog lists it simply as “Spotter Solution Tank”, and it is ordered together with parts 19491, 19510 and 19937, the recovery tank and the components that sit inside it. It also fits the Tornado PS8226 Spotter 98226, the 230-volt build of the deluxe PS Series spotter.

Tornado’s factory cross-reference returns this tank across the PS Series spotters from Series C onwards. A tank is the most machine-specific part on a spotter, so call us at 763-535-0770 with your model and serial number and we will confirm it against your machine before you order.

What the solution tank does

A self-contained spotter carries both its clean and its dirty water. This is the clean side: the solution tank holds the detergent solution, and the pump draws from it and sends it out to the tool at working pressure. The tank is pressurised only on the pump’s outlet side, but it is the reservoir the whole spray circuit depends on, so a crack or a failed seal here stops the machine spraying rather than merely leaking.

It is also a structural part. The tank body carries the vacuum motor and shroud assembly above it and seats against the recovery tank, which is why a distorted tank shows up as a machine that will not close and seal properly even though every individual gasket is new.

When to replace the solution tank

The reasons are physical. Look for cracks — most often around the mounting bosses, the outlet fitting and anywhere the machine has been dropped or knocked. Look for stress crazing, the network of fine white lines that precedes a crack. And check the sealing faces: a face that has warped will not seal to its gasket, and no amount of new gasket will fix a tank that is out of true.

Diagnose before you buy, because this is one of the most expensive parts on the machine and cheaper causes produce similar symptoms. Solution disappearing faster than expected, or a damp patch inside the housing, is far more often the solution tank gasket, a loose fitting or a split hose than a failed tank. Replace the tank when you can see the damage, or when you have ruled the cheaper causes out.

Fitting notes

Renew the gaskets and fittings as a set rather than reassembling a new tank around old seals — they have taken their set on the old tank’s faces and reusing them is the quickest route to chasing a leak in a machine you have just rebuilt. Transfer the fittings carefully and check each one for thread damage before it goes back in; a fitting that was weeping on the old tank will weep on the new one. If the tank failed because the machine was dropped, inspect the pump plate, the brackets and the recovery tank for damage from the same impact.

Frequently Asked Questions

What does the Spotter Solution Tank 19490 do?

It holds the clean detergent solution that the pump draws from and sends out to the tool. It also carries the vacuum motor and shroud assembly above it and seats against the recovery tank, so it is a structural part as well as a reservoir.

How do I know if the solution tank needs replacing rather than a gasket?

Solution going down faster than expected or a damp patch inside the housing is usually a gasket, a loose fitting or a split hose. Replace the tank when you can see cracks (typically at the mounting bosses or the outlet fitting), stress crazing, or a sealing face that has warped out of true.

Why does Tornado list this tank with 19491, 19510 and 19937?

Because the tanks and the parts inside them only work as an assembly — 19491 is the recovery tank, 19510 the intake stack tube and 19937 the vacuum motor shroud. Tornado’s catalog note tells you what to order alongside the tank so the machine goes back together complete.
