I cant get my pump to prime and keep the pressure high in the bowl.

Hi Lauren the easiest way to Blead these systems is to suck the fuel through the return line at the filter. This pulls all the fuel and air through the high pressure pump and primes the injectors. This is the most efficient way to do the job. Because even a small amount of air in the high pressure pump will prevent it from starting.

most pumps that won't prime are not recieving a good seal on suction line (inlet) ck alll the fittings for good o-rings and ck filter lid as well , hairline cracks too can develop in hard plastic over time and rough treatment this can lead to loss of prime , one other reason and it's the most expensive reason is pump seal at drive end has went bad and sucking air if your handy with a wrench then you can source a new seal from jacuzzi if not replace entire pump (thats the expensive way)

keep going...i mean disconnect the supply line from the fill valve, hold the line into a bowl/bucket and slowly turn the water on. is there pressure? sorry for delayed response if you text me back i will try to answer expeditiously:)

Paint sprayer.
Flip lever down to prime > paint comes out small plastic hose.
Flip lever up to put pressure on spray line.

Problem: prime keeps running and spray line never gets pressure.

Future solution:
You did not clean sprayer very well last time, or it is rusted. When cleaning, run full 5 gallons of cleaner through machine twice.
You should fill spray line and pump with kerosene if machine sits idle more than few days.
We all forget.

Good news: you have prime. If machine doesn't prime, you probably have to disassemble.

More good news: There are two steel balls inside pump. Tap top one with hammer to loosen. Keep machine running. Keep lever up. Start tapping top one. Tap a little harder... keep tapping ... sometimes it will not free up ... take apart pipe and see if you can nudge ball loose >> be careful not to scratch anything... the sprayer is high pressure and all parts have to fit

It could be any one of the following problems. Try these troubleshooting steps for Jaccuzi pool pumps.

1)Pump not primed. Prime pump.
2) Leakage of air into suction system
3)Impeller clogged
4) Valve in suction or discharge line partly closed; Suction or discharge

line partly plugged or too small.

5)Plugged basket in skimmer or hair in lint strainer.

6)Dirty filter.

TIME TO BUY A NEW COMPLETE PUMP !! I RECOMMEND A STA-RITE DURA GLASS PARTS FOR THE JACUZZI ARE HARD TO FIND AND $$$ SCRAP IT REMEMBER TO PRIME YOUR NEW PUMP ... THUMBS UP IF I WAS OF HELP.. THANKS JAY.. THE POOL PUMP REPAIR GUY

They only need to be tight enough to sufficiently seal the donut between the tank and the bowl. Some movement is acceptable. It is better to be a little loose than to overtighten them and risk cracking the tank.

The number one problem is air leaks.......check all connections to see that they are tight, and rubber seals. The intake side would give you trouble with air leaks. If you dont find any leaks then I would pull the pump cover and check the impellor. Pool stores have parts and lots of knowledge.

With the Jacuzzi Magnum pool pumps, low pressure is going to likely be cause by one of the issues below. Try these troubleshooting tips.

1.Pump not primed

2.Leakage of air into suction system

3.Impeller clogged

4.Valve in suction or discharge line partly closed or suction or discharge line partly plugged or too small. 5.Plugged basket in skimmer or hair in lint strainer.

6.Dirty filter.

You need a new impeller kit. Does any one know where to find one?
