The RIVULIS 14000400 is the Mazzei K-184 Suction Kit, a plumbing accessory designed to support proper suction-side connections for Mazzei injectors sized at 1/2 inch and 3/4 inch. Mazzei injectors operate on the venturi principle, drawing a liquid or gas into a pressurized flow stream. The K-184 kit supplies the fittings and components needed to complete a clean, leak-free suction port assembly. It is typically installed by irrigation technicians, pool service professionals, or plumbers working with chemical injection, fertigation, or water treatment systems where precise additive dosing is required.
This suction kit is used wherever a 1/2 inch or 3/4 inch Mazzei injector is installed in a pressurized line. Common applications include agricultural fertigation systems, pool and spa chemical dosing, municipal water treatment, and industrial fluid injection setups. The kit ensures the suction port of the injector is properly plumbed, which is critical for reliable and consistent injection performance. It is suitable for both new installations and replacement service on existing injector assemblies.
Designed for use with 1/2 inch and 3/4 inch Mazzei injectors. Verify injector model and port size before ordering to confirm fitment.
Installation should be performed by a qualified irrigation technician, pool professional, or licensed plumber familiar with pressurized chemical injection systems. Shut off system pressure and isolate the injector from the line before disassembling the suction port. Ensure all fittings are rated for the fluid type and concentration being injected. Follow all applicable local plumbing codes and chemical handling regulations during installation.
