I just had a couple of deionized water tanks installed today and am having some problems with water delivery. As you can see from the photos, the two valve levers allows me to switch between using water straight from the tank, or allowing water from the tank to flow through the filters for the final rinse.



When I have it set up to take water straight from the tank, the water pressure pulses high and low, and when I have it set to go through the DI tanks, I get nothing.



Would installing a water pump solve this? I was thinking of a Shurflo pump from Northern Tool. I`m assuming that I would place it in between the 3 way fitting (not sure exactly what its called) and the red hose. Also, the pumps that I saw on the Northern Tool site seem to have male ports on both sides. Wouldn`t I need a male and a female port? As you can see, I`m not too keen on plumbing issues, so any help would be greatly appreciated.
