Ask for the model and target
Get manufacturer, model, media and capacity details. State the measured condition or preference being addressed, and the sample point used for any measurements. A package name alone does not establish which filter, softener or drinking system is included.
Make installation visible
Ask the proposal to identify bypass, drains, overflow, power, treated outlets and access. Confirm site-specific permit needs and the work excluded from the price. Include removal of old equipment when relevant and distinguish optional upgrades from requirements.
Keep ownership costs explicit
Request consumables, expected service tasks, warranty conditions and the acceptance check. Do not compare a bare equipment price with a fully installed scope. A promotional starting price needs its qualifying system and exclusions stated before it can be used as a budget.
House, additional buildings and private-well boundaries
For a Wellington request, identify the supply serving each building before discussing equipment. A household connected to municipal water differs from a house on a private well, and a barn or irrigation line may be a separate scope. List the affected outlets and the demand the proposal is expected to serve. Do not apply a domestic equipment recommendation to animal-care or other specialist uses without the relevant professional guidance. A written line map helps the provider assess the correct project.
