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.

What is included in the kit?

Union, check valve, elbows, nipples, hose adapter, Banjo ball valves, cross fitting, Y filter, pressure gauge, and roll of pink Teflon tape.

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.

Is assembly required?

Yes. Assembly of all plumbing components is required during installation.
