The retrofit line item that decides the budget

Fire Pumps, Jockey Pumps and Backflow Preventers

Aurora (Pentair) · Peerless Pump Canada & United States $$$$ · Often the most expensive single components of a retrofit

Fire pumps boost city water pressure for sprinklers and standpipes; backflow preventers stop sprinkler water from flowing back into the drinking-water supply. When a sprinkler retrofit goes over budget, these are usually why.

Why we like it

  • Lets a sprinkler or standpipe system meet its design pressure when the city supply cannot
  • A jockey pump holds system pressure so the main pump does not start for minor drops
  • Controllers are listed and monitored by the fire alarm panel

Watch out for

  • Often the most expensive single components of a sprinkler retrofit
  • Weekly or monthly churn testing plus an annual flow test
  • No reliable public cost figure
Best for

High-rise buildings, ESFR warehouses and any building whose water supply cannot meet sprinkler or standpipe demand.

How it works

An electric or diesel fire pump starts automatically when system pressure falls, as it does when a sprinkler opens. A small jockey pump tops up pressure to cover minor leaks so the main pump does not start unnecessarily. Backflow preventers — double-check or reduced-pressure assemblies — sit at the connection to the municipal main and stop system water flowing back into the drinking supply. The pump controller is listed and reports its status to the fire alarm panel.

Who needs it

Buildings whose water supply cannot meet sprinkler or standpipe demand — high-rises and ESFR warehouses in particular. Backflow preventers are required at the city connection by water utilities.

Codes, standards and listings

Canada
Fire pumps installed to NFPA 20; pumps and controllers ULC-listed or FM Approved. Backflow prevention required by provincial plumbing codes and municipal water utilities.
United States
Fire pumps installed to NFPA 20; pumps and controllers listed to UL 448 or FM Approved. Backflow prevention required by plumbing codes and water utilities.

What the market looks like

Fire pumps are supplied through sprinkler contractors and pump packagers, from manufacturers such as Aurora (part of Pentair) and Peerless Pump. Backflow preventers are required by water utilities and plumbing codes and tested by certified backflow testers. We found no reliable public cost figures.

Features that actually matter

Electric or diesel drive
Diesel runs without grid power but needs weekly testing; electric may be tested monthly where conditions allow.
Jockey pump
Maintains pressure to avoid nuisance starts of the main pump.
Listed controller
The controller is listed and supervised by the fire alarm panel.
Backflow assembly
Double-check or reduced-pressure type at the city connection, as the water utility requires.

What it really costs

Up front
No reliable public figure — get quotes.
Consumables
Diesel fuel for diesel pumps.
What else you'll need
Pump room or enclosure, power or fuel supply, and in some cases a water storage tank. No reliable public figure — get quotes.
Over five years
Weekly (diesel) or monthly (electric) churn tests, annual flow tests and annual backflow testing. No reliable public figure — get quotes.

No published cost source was found for fire pumps or backflow preventers; figures must come from contractor quotes.

How it differs from the alternatives

Hydrant flow test first
A flow test at the nearest hydrant tells you whether you need a pump at all. It is the cheapest step in scoping a retrofit.
Electric versus diesel
Diesel keeps working in a power cut but needs more frequent testing and fuel management.
01

Buying it

Effort Major project

Where: Not sold to end users — supplied and installed through sprinkler contractors and fire-pump packagers (Aurora/Pentair, Peerless Pump). Backflow assemblies are installed by the sprinkler or plumbing contractor and tested by certified backflow testers.

Lead time: Pump packages are engineered to the system; lead times vary — ask early

Get a hydrant flow test before scoping any sprinkler retrofit.

02

Installing it

Effort Major project

Time: Weeks, including the pump room and acceptance test

You'll need: Contractor install

Acceptance testing of a new fire pump is witnessed and must meet its rated performance.

03

Living with it

Effort Hard

NFPA 25: weekly churn tests for diesel pumps, monthly for electric (with conditions), and an annual flow test. Most water utilities require the backflow assembly to be tested every year.

If not this, then what

  • Water storage tankSometimes paired with a pump where the city main cannot supply the needed volume.
  • Redesigning the sprinkler systemA lower-demand design can sometimes avoid a pump; ask the designer to check.

Caveats

  • These are retrofit budget killers; get a hydrant flow test before scoping a sprinkler retrofit.
  • No reliable public cost figures were found for pumps or backflow assemblies.
  • Code requirements differ by province, state, city and code edition. Confirm with your authority having jurisdiction (the local fire official or building department) before relying on a specific clause.
Our verdict

You do not choose a fire pump; the hydraulics choose it for you. Get the hydrant flow test done first, then compare quotes knowing whether you are buying pipe or a pump room.
