Question about Pentair 3/4HP Pinnacle High Performance Inground Pool Pump

1 Answer

Only one pool return is working, there is no pressure in the skimmer basket and I already ran water into the basket by the pump to prime it. No water shoots out of the top of the filter when it is open either.

With the pump off and the basket out reach inside the pump with some needlenose pliers and see if something is clogging the impeller. It will be inside the hole behind the pump basket and will feel spongey when you reach in there. If so work it counter clockwise and when it loostens up pull it out with the pliers. Hope this helps.

How do i prime this swimming pool pump?


The normal procedure would be to unscrew the top of the inlet basket and fill that with water until it flow out down the inlet pipe, then replace the top cover. Make sure the skimmer box basket is clean, the pool water level is high, or put a fast running hose in the skimmer box to make sure the primed pump does not have to pull the water up from too low at the inlet.

If it will not pull the pool water in when started, then -
- there is a leak or blockage somewhere on the inlet side
- the pump impeller is damaged
- the filter is clogged too much and causing back pressure
- the pump power and pipe sizing are mismatched

Pool cleaner starts and then stops working


Check for water flow / water flow restrictions / and water flow blockages.

Many things create water flow reductions: Dirty filters, plugged impellers, packed with debris baskets - both skimmers and at pump, closed to partially closed valves, air suction leaks: worn shaft seal, worn orings at pump lid or pump volute body, low water level, stuck skimmer weir blade/gate in the up position & skimmer empties and air is sucked into the system which may cause the pump to lose prime. This a problem that goes un-noticed and is hard to detect even by some service technicians!

How do I remove air from pool filter lines?


with out seeing your set up not to easy,but lets try
1 your pump room is below surface of pool, make sure your pool level is high enough to return water to pump via the skimmer hole in side of pool at surface level. water should fil pump basket. check that you have a good seal on glass cover. no water in basket check if valve from pool is open still no water close valve fill filter chamber with a hose close glass cover start pump and open valve immediately.
2 pump room above pool level, close inlet valve fill pump filter with water close glass cover securely start pump and open valve.
a good drawing of you equipment and its position relative to pool how and ware u connect vacuuming hose

My pump is not drawing water from the pool, dissambeled pump and it is clean and free of obstructions. removed pump from motor and inpeller is spinning when plugged in and the defuser seems to be ok...


Ok I''m assuming the pump is mounted higher than the water level in the pool. This means it needs to be primed. If everything is air tight, it should be self priming. Check to be sure your piping is open from the skimmer to the pump and not clogged. You can put a garden hose into the suction line of the pump and feel for flow coming up out of the bottom of the skimmer. If that is ok, then fill the pump strainer basket with water. Be sure filter is selected to filter. Make sure that the basket cover is tight to the cover gasket. After filling basket with water, quickly close the cover and start pump. If it still doesn't work, fill the basket again with water and check for any leaks. If the mechanical seal is leaking, it will not self prime. I'm not sure what type of pump you have, but Hayward has complete manuals for their pumps on www.haywardnet.com. Most pumps work about the same. GOOD LUCK!

My pool pump won't prime


If the pump is above the pool water level the it is unlikly that the tank will fill completely with valves open (which is ok).Most pumps are self priming and will pick up a prime with water level below suction inlet on strainer. Try starting on main drain again and slowly open skimmer line. Did you remove water from skimmer line and winterize(if in cold weather climate)during closing?.I know this sounds stupid, but make sure water level in pool is well into skimmer. If air situation remains after scspriggs' and these thoughts then prepare for a pressure test on skimmer line to determine location of leakage.
