They are plastic though, whilst water flushed toilets, eg in pubs, are always (?) ceramic. Seems that it could be retrofitted easily by replacing the trap if the materials aren't important. I wonder if patent expiration is responsible for the apparent increase in use of similar systems. Thanks for your correction. https://www.waterless.com/how-do-waterless-urinals-work/ |
