Instead of running the waste directly to a drain, why not to a container where you can physically measure the in, and out volumes to verify the pumps are in sync? When it's time, open a drain for the waste, and refill the new water tank... I'm not entirely convinced that two identical pumps on the same shaft will pump identical quantities of water over a period of time. Knowing exactly how much you pumped both directions would allow you to know if adjustments are needed.
I agree to a degree, but as much as mechanically possible for the money spent they are going to be pretty close. Plus you are replacing saltwater with saltwater any change in salinity would take a massive difference in flow rates. And unless u plan on not checking your salinity for months on end I feel and minute adjustments would likely not be an issue.
