From December 7th – December 13th we scheduled our wash day surge stress, representing an overload of laundry. Our interpretation was slightly different because in our cabin we use a LG washer dryer combo , that takes over 3 hours to wash and dry.
Our simulation was to run our system hard using the sinks, shower as well as laundry. Our idea being to simulate a household inviting friends and relatives over to use your running wash water to take many 20 minute long showers and wash their hands 25 times.
Here’s what happened:
Day 2: On the second day the sewer and demand pumps in the house were moved from the battery to a 12v power source.
The kitchen sink did not empty well but the larger sink allows for more standing water. Bathroom sink doesn’t hold much water in the sink, so it needed to be operated more often.
Manually running the house to use 58 gallons of wash water took over an hour at the end of the second day. The fixtures did not seem to empty well when they all are operating at the same time. The air compressor could not keep up emptying all the holding tanks at once.
Day 3: 3x loading, total test took 11 hours for 3x treatment and loading. Bathroom sink starting emptying more and more slowly throughout the loadings. Kitchen sink took forever to empty. Drain valve will open and immediately close.
Treatment side of this stress test went fine on all days.
Wash water certified lab samples were collected on December 7th and again on December 14th. Please follow the links to see the results which all met and exceeded the DECs requirements:
