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 are still using it in 2021 and have found no problems with it at all.
