Soil/Sediment build up in Mains Water- Leak?

Anyone?

Have you checked the incoming supply lines for leaks? Also, have you checked the drain for backup when unit is draining? Probably one or the other. Stay/watch/and check all lines during each cycle.

There is no "soil" getting into your main water supply. Remember that the water line is at 40+ psi. No dirt or anything else can get into it. The crud under your washer was probably due to a very slow leak in one of the washer's connections, gaskets, whatever. Over time, residue of soapsuds, etc would look like dirt. If your water supply has a tint, it is likely to be from rust on the inside of steel pipes either on your property, or more likely in the mains out in the street. The amount of solids in the water is extremely small.
