Accessories

Browse our full range of water tank accessories, including fittings, sensors, level indicators, and altitude valves designed to complete and enhance your water storage system. Whether you're monitoring tank levels, controlling water flow, or connecting pipework, these accessories help keep your system running safely and efficiently.

BULKHEAD FITTINGS
Bulkhead fittings create a sealed inlet or outlet connection through a tank wall, letting you plumb in fill lines, drains, and overflow piping. Available from 1/2" up to 4" or larger, in nylon or polypropylene construction with female NPT threading, sized to match the wall thickness and dome curvature of your specific tank for a proper watertight seal.

TANK LEVEL INDICATORS & SENSORS
Keep track of exactly how much water is in your tank with a level sensor matched to your application. Float sensors extend a probe into the tank with continuous sensing elements activated as the water level rises or falls — a reliable, low-cost option for most storage tanks. Ultrasonic sensors mount at the top of the tank and measure the echo time of sound waves bounced off the water's surface, giving a non-contact reading with no moving parts in the water. For more demanding applications, capacitive, hydrostatic, and radar sensors offer additional accuracy and remote monitoring capability.

ALTITUDE VALVES
An altitude valve automatically controls the water level in a tank without electricity, floats, or electronic sensors — it senses tank head pressure through a pilot line, closing when the tank reaches its set level to prevent overflow, and reopening as the level drops to allow refilling. This makes altitude valves a reliable, low-maintenance way to manage fill cycles on elevated or ground storage tanks, particularly useful as a mechanical backup or primary control where continuous power isn't available.

From basic bulkhead connections to full level-monitoring and automatic fill control, our accessories are selected to work with the tanks we carry and help your water storage system run safely with minimal manual intervention.

The EPC 12 is a versatile electronic pump controller built for 120V and 240V systems. It manages pump operation based on system demand, with adjustable pressure setpoints and dry-run protection. This version does not include a pressure tank and is ideal for custom setups where a separate tank is used.
