We KNOW Cisterns! And we make the pumps and controls in them fully accessible. This is a 300 gallon vertical cistern. We sneak pumps and controls in these cisterns while still having full access to the equipment. This cisterns are great in garages when only some storage is needed. This is the fill line so that when one cistern fills to the top then the other cistern begins to fill. This is a 1700 gallon cistern with a hydrant, ready to be backfilled. Not very often . . . but in very cold areas, we put some insulation down and then backfill over it, to keep the water from freezing. These are incredibly strong 2500 gallon cisterns that have large flat areas for the water connections at the bottom. They actually have pillars inside of the cisterns. We build manifold systems in each cistern. This allows full access to the pump and float switches. Ready for the 5000 gallons of storage to be backfilled. That float valve is a unique and VERY reliable valve that doesn't pinch off the water. It fully fills and then shuts off. Then it fully opens. AND it's fully accessible. We try to keep our prices down by buying full semi-loads of cisterns.
