This idea of a recirculating shower system started a year ago. This was before even looking to purchase a van. I knew this was one of the problems I needed to solve to make the van a success. Finally installing this in the van brought the design full circle. Now I can shower in the van instead of my garage.
So far these pumps have been excellent. We have two in our van build. They have a 4 year warranty, which I have not needed to test since they have been working without error. But I do have an extra one just in case there is a problem. They have variable flow to reduce cycling.

As an added precaution we have a UV water sterilizer on both our reverse osmosis drinking water system, and our recirculating shower.

We have a reverse osmosis water filtration system in our van. So, we can be confident our water is clean and safe during our travels. In a video I show how I added valves to select when the system is in filtration mode, or in full reverse osmosis mode.
