It sounds like you have a reasonable start on a drain system (the hardest part to a drip/trickle system). Just hard plumb the drain outside to your favorite tree or bushes. Then tap off the nearest cold water line and run flexible (ice maker) line to each of your tanks. I put a tiny valve on mine so I can adjust the flow to each tank when needed or you can put a irrigation tip that’s set for .5 gallons or whatever you want.
Start out with just a couple of your tanks you don’t care about like: Convict feeder stock, Goldfish grow out feeders and so on. Use unfiltered tap water (shutter) just to build up your confidence. Once you see that your fish will be fine and actually thrive on trickled unfiltered tap water, run some more lines to the breeder grow out tanks and so on.
Eventually you will be at 100% unfiltered tap water, money in your pocket because you won’t be spending it on prime and lots of time on your hands because you forgot what a water change is like![]()
I have a couple of drip/WC systems under my belt from the last house. So this aint my first rodeo when it comes the these. I honestly had better luck with the automated water change system than I did with the drip emmitters with a constant flow.
I'm not sure I could get away with unfiltered/untreated tap water. It's coming out of the tap right now smelling like bleach. We also have chloramines most of the year. No way to break that bond without some sort of filter.
