↔Define interfaces
Identify inlet connection, pipe sizes, available flow and pressure, electrical supply and any installed controller. Attachments can be discussed after contact; describe the relevant dimensions in the initial request.
Supplier replies should identify every adapter and regulator included rather than assuming the buyer can source missing interfaces locally.
≡Compare scope
Request separate lines for distribution tubing, filtration, fertigation and controls. Note whether each line is supplied as a roll, piece, set or complete zone assembly.
Keep the quoted quantity, unit, material, packing and destination consistent. A substitute needs its own specification and price line, not a silent description change.
⌕Review evidence
Ask for data sheets, installation instructions, recommended filter requirements and spare-part identification for the specific configuration. A general catalog is not confirmation that an option suits your site.
Sample availability, sample charges, inspection arrangements and document access are confirmed with the proposed supplier before an order decision.
