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 raw well and backwash supply
On a Loxahatchee private-well property, keep the well, pump and existing treatment sequence in the same assessment. Photograph each stage in the direction of flow and label any sample point before the equipment. Describe whether the well also supplies irrigation and whether the household notices changes while other water is running. Raw-well testing and available maintenance flow can alter the proposed sequence. A municipal city report or a neighbor’s installation does not specify your well system.
