When we use our washer, we lose much more water than an average wash cycle. As an example, we can easily lose a half of tank of pure water during any given wash cycle. We have no noticeable leaks. Is there a shut-off valve that regulates the amount of water running into the washing machine from the fresh water tank and then on to the holding tank? Can water move from the pure tank through the wash machine to the holding tank vis a vis a faulty shut-off value during a wash cycle?

If so, where would the valve be located and can the valve remain slightly open while the washer is operating??

Any other thoughts???
