Plan service in our 47-state service area
PFS coordinates hydrant flow testing, pressure recording, municipal field programs, annual inspection support, flushing support, and system assessments across 47 U.S. states. Project location, access, authority coordination, crew requirements, and reporting needs are confirmed before mobilization. Identify the full week and operating periods that matter to the project. Provide a location approved for the observation and a contact for access throughout the recording period. Retrieval, the usable interval, and any known recording gaps are documented.
Compare a full week
A seven day observation provides a longer record for comparing weekdays, overnight periods, and weekend conditions. Tell us which operating periods matter to the project so the start date covers the intended interval.
Plan placement and retrieval together
The water authority requirements, approved location, access contact, and observation window are confirmed before the recorder is connected. The equipment is temporary and is removed when the agreed observation ends.
A usable pressure record
The report scope can include the recorded chart or trace, observation dates and time reference, recurring changes, high and low periods visible in the record, and any known gaps or field limitations. The available detail depends on the instrument and recording method.
Pair observations with the right field test
A pressure history adds context to water supply review but does not measure flowing GPM or replace an engineering evaluation. A coordinated hydrant flow test or system assessment can be scoped when those additional field records are needed.
Confirm the location and scope
PFS is based in Pelham, Alabama and coordinates national mobilization across 47 U.S. states. The service request identifies the actual water supplier, operating permissions, access, schedule, and deliverable. A city mailing address alone does not determine the water authority or its procedures.
