IPSO / Speed Queen Water Valve Leak and Change
One of the problems with vinyl tile floors in the Laundromat is that the glue is water based so if you get a small leak it gets under the tile and squeezes out when it gets stepped on.
In this video, you can see how the tiles were getting loosened and where the source of the leak was.
The failures I have had on these valves have all been in the same place on the valve. Some valves fail due to solenoid issues, dirt in the lines and other similar issues. The main reason I have seen these valves fail has been due to a failure in the housing creating a mist of water spraying into the machine.
Hope this helps.
