Reliance Flush-N-Go 3320 Portable Toilet Review

If the hardest part of a portable toilet is getting used to a bag-style setup, a flush model may feel more familiar. The Reliance Flush-N-Go 3320 Portable Toilet brings a bowl, flush water, and a holding tank into one portable unit.

Reliance lists a 17-inch seat height, a 2.5-gallon fresh-water tank, and a five-gallon waste tank. Those are useful numbers for deciding whether this belongs in an RV, a cabin, or a household backup area rather than a small travel bag.

What the 3320 Is Built to Do

• Separate tanks: Fresh flush water stays apart from collected waste.
• T-slot flush nozzle: Directs water around the bowl.
• Waste-level indicator: Helps monitor the holding tank.
• Swivel emptying spout: Supports the disposal routine.

A Flush Doesn’t Make Waste Disappear

The main tradeoff is that the holding tank eventually needs emptying. I would identify an approved disposal point before relying on this for several days. Tank capacity isn't useful if the only available place to empty it is unsuitable or inaccessible.

Also consider the filled weight when planning transport. Reliance lists the empty unit at 12 pounds; water and waste add to that. The person doing the emptying needs to be comfortable with the complete process, not just the seat.

Comfort Versus Storage Space

The standard-height format could be welcome for someone who dislikes low camping seats. It also takes up a meaningful amount of floor space. Measure both the storage spot and the area where it will be used, leaving room to manage the tanks and lid.

I would compare the Flush-N-Go for longer temporary setups where a familiar toilet routine is worth the bulk. For an occasional roadside stop, a simpler bag-compatible model may be easier. This one earns its place when the user values the flush arrangement and has already solved the water refill and tank-disposal parts of ownership.
