Presscision PPT is a test instrument that is the plumbing industry’s first of its kind digital pressure & temperature test platform designed exclusively for the plumbing industry. It utilizes state of the art technology that provides the means to significantly improve the efficiency, accuracy and reliability of regulatory and non-regulatory testing. The modern test platform provides the highest level of safety while efficiently minimizing the risk associated with a failed or improperly conducted test.
The Presscision PPT instrument was designed to take maximum advantage of modern, digital technology. Core features of the instrument design include:
1. The instrument incorporates accurate, stable, digital sensor technology for pressure and temperature measurements. The instrumentation is calibrated against a pressure reference traceable to NIST standards to guarantee and certify the level of accuracy.
2. The instrument uses test automation to remove the human from the test process. This eliminates human error in conducting the test (testing at an incorrect pressure or for an incorrect duration), and human subjectivity during the process of reading an analog gauge.
3. The instrument automatically generates a comprehensive, permanent, and tamper proof record of every test. Test records can be recalled and printed at any time, providing conclusive evidence of a test.
The PPT instrument provides the functionality of three separate test instruments in one easy to use device:
The PPT instrument is designed to support the pressure and temperature testing requirements for commercial and residential plumbing in satisfaction of regulatory codes.
The instrument can also be used for non-regulatory testing, for example:
The instrument provides pre-established test types for the conduct all pressure and temperature tests. The standard test types supported include:
Fuel gas installations (natural gas or propane)
Drain waste vent lines (DWV)
Water supply lines
Fire suppression systems
Radiant heating/cooling systems
Leak Test (non-regulatory): used for generalized leak detection
Monitor Test: used for long term pressure/temperature monitoring and pressure transient capture
Custom test (non-regulatory): used for training or for conducting short tests to check the instrument setup
Plumbing fixture water temperature testing following installation and/or adjustment of water temperature limiting devices used on tubs, showers, bidets, whirlpools, etc.

The instrument provides an easy to use, step-by-step process for the setup and conduct of a test. All tests conducted by the instrument use test parameters (minimum test pressure and test duration) established by the operator. As a safeguard, the PPT instrument will not allow the operator to define minimum test pressures that are outside of the measurement ranges of the attached sensor. Further, pressure tests cannot be initiated if the initial plumbing pressure is below the minimum test pressure specified by the operator.
The media, pressure and duration test parameters established by the user for the specific test type selected are also subject to state and/or local regulatory codes. The PPT instrument includes limits on allowable minimum and maximum ranges for test pressure and duration. These limits are based on model regulatory codes published by the International Code Council (ICC).
The test process includes the following steps:
