Description
Fire Sprinkler Hydrostatic Test Pump with a One-Way Valve Hose
Product Overview
A hydrostatic test drags on when the pump fills the piping slowly or cannot hold a steady pressure while the inspector reads the gauge. The Triple R HT-89A hydrostatic test pump delivers 3.0 GPM open flow, stops adding water at the set pressure, and disconnects from the system without releasing test pressure. This 300 PSI hydro test pump electric runs on a standard 115V outlet.
Key Features and Benefits of Triple R HT-89A Hydrostatic Test Pump 300 PSI
- At 3.0 GPM open flow, the pump moves 50% more water than a 2.0 GPM pump, so long pipe runs fill in less time. Open flow is the pump's flow rate with no system pressure applied.
- This hydrostatic test pump with pressure regulator control closes off the water supply once the set pressure is reached. A built-in full-flow bypass and pressure protection system guard against over-pressurizing the pump and burning out the motor.
- The 10-foot quick-disconnect hose has a built-in one-way valve, so the pump can be separated from a pressurized system. Inspectors often require that step to confirm the system holds pressure on its own.
- The ½ HP ball bearing motor has a 115% service load factor, which allows continuous operation at 0.575 HP without damage. Triple R rates the pump 20% more efficient than comparable units.
- A liquid-filled stainless steel gauge steadies the needle against pump pulsation and vibration, so readings are easier to take.
- At 35 lbs with a carry handle, one person can carry the pump to the test location.
Applications
The Triple R HT-89A hydrostatic test pump covers pressure tests at or below 300 PSI on small and medium systems. It is a fire protection test pump for sprinkler fitters and a line tester for plumbers.
- Fire sprinkler and standpipe systems. Acceptance and revision tests on small and medium buildings call for a fire sprinkler hydrostatic test pump that fills lines steadily and holds pressure through the inspection.
- Plumbing and water lines. A 300 PSI electric hydrostatic test pump checks water piping for leaks before walls are closed or trenches are backfilled.
- Water transfer and line filling. Restoration and carpet cleaning crews use the pump for small water transfers and vent-line filling.
- Indoor and enclosed spaces. This electric pressure test pump runs without fuel, so there are no exhaust fumes in basements or mechanical rooms.

HT-89A vs REED EHTP500
The HT-89A vs REED EHTP500 decision comes down to test pressure versus fill speed. The REED EHTP500 reaches 500 PSI at 2 GPM. The Triple R HT-89A hydrostatic test pump tops out at 300 PSI but delivers 3.0 GPM open flow, so it fills piping faster on tests within its rating.
| Triple R HT-89A | REED EHTP500 | |
|---|---|---|
| Maximum pressure | 300 PSI | 500 PSI |
| Flow | 3.0 GPM open flow | 2 GPM |
| Motor | ½ HP ball bearing, 115 VAC | ¾ HP, 110V |
| Pressure control | Built-in regulator and full-flow bypass | Adjustable regulator knob, automatic recirculation at test pressure |
Each is a hydrostatic test pump with pressure regulator control built in. When a larger system needs more flow than a 300 PSI electric hydrostatic test pump provides, the Triple R HT454 delivers 4.5 GPM open flow at up to 400 PSI.

Frequently Asked Questions
What is a hydrostatic test pump used for?
A hydrostatic test pump fills a closed system with water and raises it to a set test pressure, so leaks and weak joints show up before the system goes into service. Typical jobs include sprinkler piping, standpipes, and water lines. The guide to hydrostatic testing pumps covers each step.
How does a hydrostatic test pump work?
An electric motor drives a stainless steel plunger that pushes supply water into the system. On an electric pressure test pump like the HT-89A, the regulator closes off the supply at the set pressure while the gauge shows the reading.
What size hydrostatic test pump do I need?
Pick a pump rated at or above the required test pressure, then compare flow, since GPM sets how fast the piping fills. A 300 PSI electric hydrostatic test pump suits tests at or below that pressure. Confirm the required pressure in the project specification.
Is it better to rent or buy a hydrostatic test pump?
Buying usually makes sense for contractors who test regularly, since rental fees add up and rental units are not always available. Owning a Triple R HT-89A hydrostatic test pump also means the gauge, hose, and regulator are in known condition.
Can the HT-89A be used for fire sprinkler testing?
Yes, for systems tested at 300 PSI or less. It is a fire sprinkler hydrostatic test pump sized for acceptance and revision tests on small and medium buildings. Confirm the test pressure and duration with the authority having jurisdiction (the local fire or building official).
