Dilution Solutions Nutrient Delivery System (NDS) DAB Booster Starter Kit, 3/4 in

NDS DAB Booster Starter Kit for 3/4 Inch Lo-Flo Systems – HYKSTART-DAB

The Dilution Solutions HYKSTART-DAB is the Starter Kit for 3/4-inch Lo-Flo NDS installations that use a DAB booster pump to supplement inlet water pressure. In facilities where the municipal or well water supply does not provide sufficient pressure for reliable Dosatron proportioning, a DAB pressure booster pump is added to the system. The HYKSTART-DAB provides the inlet-side plumbing hardware configured for integration with the DAB pump.

The kit includes a union, check valve, elbows, nipples, hose adapter, Banjo ball valves, cross fitting, Y filter, pressure gauge, and a roll of pink Teflon tape. Assembly is required. For installations with adequate supply pressure that do not require a booster pump, use the standard HYKSTART Starter Kit (DSSK34) instead.

Key Features & Benefits

• DAB Booster Pump Integration — Plumbing components configured for NDS installations using a DAB pressure booster pump.
• Check Valve Included — Prevents backflow from the injection side into the supply or pump.
• Banjo Ball Valves — High-flow ball valves for system control in booster pump configurations.
• Y Filter — Inline strainer filter to protect the booster pump from debris in the supply water.
• Pressure Gauge — Monitors system pressure at the inlet side of the NDS.
• Assembly Required — Field assembly of all plumbing components is required during installation.

Who Should Use This Kit

The HYKSTART-DAB is for 3/4-inch Lo-Flo NDS installations where a DAB booster pump is part of the system design. Confirm that the water supply pressure is insufficient for the Dosatron model being used before specifying the DAB configuration — most installations with municipal water supply at standard residential or commercial pressure can use the standard HYKSTART.

When Is a DAB Booster Pump Required in an NDS?

Dosatron proportional injectors require a minimum water pressure to operate — typically around 7-10 PSI at the injector inlet, depending on the model and flow rate. In facilities where the supply water pressure is below this threshold — such as well systems with aging pressure tanks, facilities on low-pressure municipal supplies, or rooftop installations far from the pump — the Dosatron may produce inconsistent proportioning or fail to dose at all. A DAB booster pump adds a small centrifugal pump to the inlet side of the NDS to boost supply pressure to the required operating range. The HYKSTART-DAB provides the plumbing components needed to integrate this booster pump cleanly into the NDS.

Frequently Asked Questions

What is the HYKSTART-DAB used for?

It is the Starter Kit for 3/4-inch NDS installations that use a DAB pressure booster pump to supplement low supply water pressure. Without adequate pressure, the Dosatron injector cannot proportion nutrient concentrate reliably.

What is included in the kit?

The kit includes a union, check valve, elbows, nipples, hose adapter, Banjo ball valves, cross fitting, Y filter, pressure gauge, and a roll of pink Teflon tape. That's the full set of plumbing hardware needed to integrate a DAB booster pump into the inlet side.

What is the difference between HYKSTART and HYKSTART-DAB?

The HYKSTART is for standard installations with adequate supply pressure. The HYKSTART-DAB is configured for installations that include a DAB booster pump to supplement pressure.

When do I need this kit instead of the standard HYKSTART?

Use the HYKSTART-DAB when your supply water pressure falls below roughly 7-10 PSI at the injector inlet — common on aging well systems or low-pressure municipal supplies. If your facility already delivers adequate pressure, the standard HYKSTART is sufficient.

Is assembly required?

Yes, assembly of all plumbing components is required during installation. Because the booster pump hardware varies by site, the fittings are supplied loose rather than pre-assembled.
