# How often should a jockey pump run?

## How often should a jockey pump run?

The jockey pump starts every 30 minutes or so when the pressure drops from 200 PSI to 150 PSI.

## What is cut in and cut out pressure of fire pump?

PRESSURE SETTINGS Set the main pump to cut in about 5 psi less than the jockey pump start pressure, and cut out at the same shut off pressure as the jockey pump. Many systems are set to cut in whenever pressure drops.

What should be the pressure to be maintained in the fire line?

All new systems are required to be tested hydrostatically at a minimum pressure of either 200 psi (13.8 bar), or 50 psi (3.4 bar) above the maximum discharge pressure, whichever is greater, at the fire pump discharge flange.

Do jockey pumps need emergency power?

Also, please confirm the Jockey pump does not require backup power.

### How do you adjust a pressure switch on a fire pump?

1) The jockey pump stop point should equal the pump churn pressure plus the minimum static supply pressure. 2) The jockey pump start point should be at least 10 psi (0.68 bar) less than the jockey pump stop point. 3) The fire pump start point should be 5 psi (0.34 bar) less than the jockey pump start point.

### How do you maintain a jockey pump?

What should the start point of a jockey pump be?

(b) The jockey pump start point should be at least 10 psi (0.68 bar) less than the jockey pump stop point. (c) The fire pump start point should be 5 psi (0.34 bar) less than the jockey pump start point. Use 10 psi (0.68 bar) increments for each additional pump.

What should be the pressure of jockey pump in fire pump?

Pressure of jockey pump shall be greater than the pressure of main fire pump by minimum of 10 psi to avoid false starting of main fire pump. For more information about setting of fire pumps, click here.

#### How does a jockey pump work in a sprinkler system?

The flow must not exceed the flow capacity of a single sprinkler head, or the jockey pump will be incapable of maintaining pressure when a head opens up to fight a fire. The object is to overwhelm the jockey pump so the pressure continues to drop in the system, resulting in the fire pump starting.

#### What is the jockey pump pressure switch shut off point?

That is our jockey pump pressure switch shut-off point. Most pressure switches will not permit a differential between off and on of less than 15 psi, so our turn-on point of the jockey pump pressure switch will be 130 psi (145 – 15 = 130).
