Do your boat have a lean to starboard when the tanks are full ?
Good use of the space. I used 3 , 5gal stainless steel fire extingushers for holding water connected to a 4 way brass water splitter (got at Lowes garden). the splitter connects to the sink and to an external water hookup. You have to remove the actuator for the extingushers and fill the hole left with JB weld. I used standard water supply lines for refridges. I found that the pressure from marina potable water systems pressurize and fills the system at the same time. In port I have unlimited amount of running water to the sink. Out to sea I have at least 5 days of running water( more or less depends upon usage). I had to modify the sink drain , put in a 2" flex line(used bilge flex line), 2" through hull fitting and 2" bar drain. Note if you put in a new flex line move it to behind the sliding kitchen sink. Works so much better actually drains in all positions. Whole project less than $500 done in a couple of weekends. Side advantage is no pumps, or pumping while washing just turn on flowing water. I have a backup dc airpump just to repressurize if needed. Also the 4 way has valves so I can isolate each tank which helps to regulate the water usage and will keep pressure in the unused tanks in the event of a leak. Been using the system for 2 years without issue.
