Jeff at Triton was very knowledgeable and the system worked great! After the machine ran for about 18 hours to filter our 15,000 gallon in ground pool, our water tested basically as purified drinking water.
I went this route because we all need to still conserve water and I couldn't see just flushing 15,000 gallons down the drain to refill with another 15,000 gallons of unpurified tap water from the city.
I will go this route every single time I need to flush my pool. Don't flush, recycle.
