Duplex Standard Water Tank for the DH 420 and DHB 420


The hybrid Duplex 420 machines carry two of these standard water tanks. Order one to replace a cracked or lost tank, or a set of 2 to have spares filled and ready on long jobs.

They fit the DH 420 and the DHB 420. The corded DP 420 uses different tanks, so send us your model before you order if you're not sure.


The Owner's Insights on Spare Tanks

A second pair of filled tanks is the cheapest way to cut refill trips on a big carpet or tile job. Swap tanks, keep cleaning, and refill both at the sink once.

Rinse and dry the tanks at the end of each shift. Standing dirty water is what makes a machine smell.

Frequently Asked Questions

How many tanks does my machine use?

Two. A set of 2 replaces both, or gives you a filled spare pair for long jobs.

Do these fit the DP 420?

No. The corded DP 420 uses different tanks. Send us your model and we'll find the right part.

How do I keep the tanks clean?

Empty, rinse and air-dry them after every shift. Standing dirty water causes odors and buildup.
