Tri-Max 3 Flow Rate Aerator
We like this aerator because we can select 3 different volumes, .5, 1.0 and 1.5 gallons per minute based on whether we are boondocking or parked in a campground with full hookups. Unfortunately, it is plastic, not metal, so who knows how long it will last. The good news is, the aerator only costs about $5 and we like it so far.
A note: we started using this in January 2020, and replaced our .25 gallons per minute aerator with this one. We will evaluate this decision and update our comments here at a later date.
