Count demand rather than bathrooms alone
Describe occupants, simultaneous showers, laundry, a large tub and any additional buildings. Bathroom count is a starting point, not a measured peak flow. Separate irrigation and other high-volume use from the domestic treatment target.
Ask for two different ratings
Service flow and regeneration or backwash requirements answer different questions. Request usable flow at the agreed treatment target, acceptable pressure loss and the supply needed for maintenance cycles. The available pump or utility line may constrain the proposed design.
Make the scope comparable
A proposal should identify tank and media size, valve, settings and which outlets are served. Compare those details alongside installation and future consumables. More stages are not automatically an improvement; every stage should have a purpose supported by the source and household goal.
The correct Seacoast report and simultaneous demand
Gardens households should confirm which Seacoast supply and report applies to the account. The main Seacoast report and West-Consecutive report are separate. For an equipment request, pair that account information with the actual household demand: simultaneous showers, laundry and other connected uses. A supplier report helps establish context but cannot determine the usable flow, hardness or maintenance requirements at your property. Tell the provider whether the installed system serves the whole domestic line or selected outlets.
