Those anti siphon valves would all have been worthless in this application, because the water would have been pouring into the tub and running down the drain. In installations where the washer does not spray into a tub, but rather discharges into a pipe, the very simple and effective method of preventing backflow is to not seal the gap between the hose and the pipe, so that there is no vacuum created by the falling column of water.

Our city also demands the installation of those anti backflow valves on any faucet that could have a hose attached, which is a totally hysterical response to a very rare problem that is trivial to elimainate. Instead we have valves that spew water out whenever the hose flow is decresed or shut off. The result is that most people remove the valves when they move into a house and only reinstall them when they move out. So the intent of the mandate is defeated, which is OK, because the problem is not real, at least in this city.

I find it odd that no one has suggested that the washer in question is functioning exactly as washers have functioned for many, many years.  When I was a kid (long ago), virtually all washers in our midwest community had a laundry tub sitting beside the washer with a snorkel shaped drain hose from the washer hanging in it.  When you wanted to save the rinse water and use it to wash the next load, you put a standpipe in the drain that would acuse the rinse water to stay in the tub.  Then when you washed the next load, the pump sucked it back into the washer and additionally filled until the full sensor stopped it.  I believe my mother used it regularly and always washed the 'cleanest' clothes first and the dirtiest last.  She probably only used a little over half as much water as she would have otherwise.  Maybe some of the areas that are experiencing or going to experience severe water shortages should be investigating renewed usage of these 'suds savers'.
