If you are using a jet pump you must have a good foot valve, then remove the prime nut or gauge from the top of the pump and fill the pump and pipe with water. You may have to do this a number of times to get all the air out of the system.
its suddenly stop working, left leg and arm
EH...... what the heck
They are synonymous. i.e., They mean the same thing. Prime Contractor = General Contractor. Some construction projects have multiple primes (multi-prime contract), where each prime is in charge of a general area of work and hires subcontractors underneath him, and one of the primes is typically delegated the owner's duty to coordinate. But the typical construction cite just has one prime.
No, dry is not an adverb.Adjective -- The dry air is bothering my allergies.Verb -- I dry my clothes after I wash them.
No, you do not have to prime the oil pump.
you dont need to prime the pump
The hole in the pipe is to break an air lock that the pump may develop if the sump ever runs dry or the water level drops below the intake of the pump. Air inside the pump might not be purged out when the water level rises and the pump is called to turn on, causing the pump impeller to 'run dry' inside the pump. The hole allows the air to escape and the pump to prime itself and operate without an air lock condition.
The pump will be ruined and need to be replaced if the car was driven with a dry pump.
Priming of any pump is the same - it means filling the pump with liquid to get it to pump because the pump will not fill itself with liquid from being dry (it won't self-prime).
To prime the oil pump on most cars all you need to do is turn the motor over without it firing, disconnect the coil and turn the key, this will prime the pump.
The plane has a collection spot on it much like a motor home or RV when it lands they pump it dry.
Your pump lost its prime. Could be a bad seal in the pump head, a bad check valve, a leak in the suction line, or a dry well.
In order for a pump to work it needs something to Prime(suck) and because water and fuels arent solid enough you have to prime it. meaning fill the suction hose up so there is no air so the pump can suck. if there is air in it it wont work. as the pump sucks up the fuel/water in the hose it drags up the rest of whats in the tank or under the ground or what every your pumping. a self priming pump has a foot valve(one way hose) on it. when the pump suck up and is turned off all that is in the suction hose does not run back out it stays in the because of the foot valve.
You do not have to prime the pump. Just add the correct amount of oil and start the engine.
If water does not flow through your pump while the pump is operating the pump will "loose prime" what remaining water in the pump will boil from the friction of the impellor spinning, this will turn the water to steam and melt the plastic parts. Also known as the pump has "Dry Run"
You do not have to prime it. It is self priming.
