Small Engines (Lawn Mowers, etc.): Lawn Sprinkling pump/ Sta-Rite, pressure control valve, lawn sprinkling


Question
QUESTION: I live in the Caribbean and we have a cistern and a pump that pumps water to the house.  The pump is a Sta-Rite 60 cycle Lawn Sprinkling Pump, 1/2 HP, model FSCH.  It is old, but works well.  The problem is that the pump comes on as soon as I turn on the water and stops quickly and then comes on again (quickly) if the water continues to run.  Is the pressure valve (?) set too high?  I see the valve, but don't know how to re-set it.
Thank you for your help.

ANSWER: Hello Nancy:

>>Sorry for the Delay. This Question was Located in the Question Pool and I can Only Answer Questions from the Question Pool when I am Not Answering Questions here or at the Other Site I Answer Questions at.
>>Can you Tell me if there is a Reservoir Tank in the Line Between the Pump and the House?
>>Usually this Style of System has a Tank that Holds 10 to 15 Gallons of Water and when the Water is Turned on the Water from the Reservoir Tank Flows into the House. When the Pressure in the Reservoir Tank Lessen to a Certain Point (the Pressure the Pressure Control Valve is Set for on the Low Side), then the Pump Kicks in and Brings the Water Systems Pressure back up to its Normal Pressure (the Pressure the Pressure Control Valve is Set to Kick Off at).
>>If Not Reservoir Tank is Used, then the Pumps Pressure Valve is Not Set Correctly and Requires Setting so the Pump Kicks On and Runs Constantly while Water is Flowing out of a Faucet at the House (or other Location) and Stops when the Faucet is Closed.
>>It has Been a While since I have Set a Pump to Operate in this Manner, but Send me a Reminder on Monday and I will have the Correct Procedure to Set the Pump to Operate Correctly without Using a Reservoir Tank.
>>A Neighbor of Mine has the No Reservoir Set up and I can Get the Procedure form his Wife. She has had me Read the Directions a Few Years Ago as he was Out of Town and the Regulator had to be Replaced and Set to Operate without a Reservoir Tank.
>>Again I Apologize for the Delay.
>>Please, Do Not Hesitate, If you Hit a Snag, if I Missed Something or this Does Not Correct the Problem, I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck

QUESTION: Thank you John for your answer.  I DO have a reservoir tank right under the pump (in the pump shed).  The pressure valve is on the pump (you probably know that).  Could it be that there is air in the reservoir tank and I need to let it out?

Thank you for your help.

Answer
Hello Nancy:

>There May be Air in the Reservoir, but Usually it is the Regulator that is the Cause of the Problem you Described.
>>When you Cut the Faucet on, Does Air Come Out with the Water of Just before the Water Does> If Not, then Air is Not the Cause of the Problem.
>>The Regulator Springs have Weakened or Corrosion is Causing the Low Pressure Lever to Engage Improperly and the High and Low Pressures Require Setting.
>>If you want Exact Instructions for Setting the Pressure Springs, then Let me Know and I will Supply them to you.
