Description
Manual Hydrostatic Test Pump for Heating, Plumbing, and Fire Sprinkler Systems
The MP8125 pressure testing pump is a hand-operated test pump rated to 725 PSI (50 bar). It pressurizes closed piping systems with water or oil to check for leaks before commissioning or after repairs. Fill the system, pump the handle to build pressure, close the valve, and watch the gauge. If pressure holds steady, the system is leak-free. This hydrostatic test pump handles everything from residential water tank testing to commercial heating loops, compressed air systems, refrigeration lines, oil installations, and fire sprinkler systems. No electricity required. It works anywhere on the jobsite.
What's Included
- Shut-off valve
- Pressure gauge
- Outlet connector hose
- Inlet suction hose with removable filter
- Handle locking pin
Key Features
- Rated to 725 PSI (50 bar) for pressure testing heating, compressed air, refrigeration, oil, and fire sprinkler systems
- This manual hydrostatic test pump works with both water and oil as the test medium, covering plumbing and oil-filled system applications
- This hand test pump operates without electricity, batteries, or fuel, so it runs on any jobsite without a power source nearby
- The pressure test pump includes a shut-off valve, gauge, and hose in the box, so there is nothing extra to buy on day one
- A locking pin on the handle prevents accidental pumping during transport or when the pump is stored between jobs
- The inlet suction hose has a removable filter that keeps debris out of the pump and flushes clean with water when clogged
The MP8125 pressure testing pump delivers 725 PSI capacity in a portable, no-power-needed package for crews who pressure test piping systems across plumbing, HVAC, and fire protection trades.

Frequently Asked Questions
How to pressure test plumbing for leaks?
Fill the piping with water, connect a pressure test pump like the MP8125, and pump to the required test pressure. Close the valve and watch the gauge for 15 to 30 minutes. If pressure drops, there is a leak in the system.
What is a hydrostatic test pump used for?
A hydrostatic test pump pressurizes closed piping systems with water or oil to find leaks. It is used in plumbing, heating, compressed air, refrigeration, oil, and fire sprinkler installations. Building codes require hydrostatic testing before new systems go into service and after major repairs.
What PSI to pressure test plumbing?
Residential water supply lines are typically tested at 100 to 200 PSI per local plumbing codes. Commercial fire sprinkler systems require 200 PSI for two hours per NFPA standards. The MP8125 pressure testing pump handles all of these ranges with its 725 PSI rated capacity.
Can this pump be used as a test pump for fire sprinkler systems?
Yes. The MP8125 is rated to 725 PSI, which exceeds the 200 PSI NFPA requirement for commercial fire sprinkler acceptance testing. It pressurizes the system with water and holds pressure while you check every fitting and connection for leaks over a two-hour test period.
Should you choose a hand-operated vs. electric test pump?
A hand-operated test pump like the MP8125 needs no power source and works anywhere. An electric test pump like the HydroTest 6334 electric hydrostatic tester fills faster but needs a 120V outlet. Choose manual for portability and electric for speed on larger systems.
