Question about Pentair IntelliFlo VF High Performance 3HP Pool Pump - 16A 230V

1 Answer

Error after short prime cycle

Pump basket fills with air overnight due to small air leak. In "filter" mode it starts in the morning, begins to flow water with a moderate pump speed, goes to high RPM and shuts down with an fault error. It has sufficient water in the basket and pump to prime and protect the seals. Restting and restarting in "filter" flows enough water after a 15 seconds or so to prevent a second shutdown. I have set the prime time from 1 to 10 minutes and the prime flow from 30 to 70 gpm but this makes no difference. There are no water leaks in the piping implying the air leak must be small. Once running, the system seems normal pulling 500 Watts to turn the 20kgal pool once a day in 10 hours. Last year it was fine.

SOURCE: My Whisperflo pump has a leak in my PVC pipe from

The correct way to repair this is to repipe the line. If you can't do that, your local hardware may have an epoxy putty that will hold against water pressure. I would only recommend that if the leak is between two pieces of PVC piping. If the leak is where the pump meets the PVC, I would recommend repiping the discharge.

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

Why has the circulation flow decreased


Your pump pushes "Unfiltered" water thru the Filter. Your filter then "Cleans / Filters" all of the microscopic particles of dirt out of the water. This will eventually clog your filter as the pressure will then obviously climb. Basically, doing the job it was intended to do! As this occurs the water flow will be reduced and at times, dramatically! The fix: clean the cartridges, backwash your sand or D.E. Filter.

Another possibility is the flow is restricted due to another type of clog: Plugged pump impeller, clogged & dirty skimmer or pump baskets, etc.

Or low water level. Sucking air with water.

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!

Sysrem keeps saying low flow


Three areas that can cause low flow 1) the intake on the pool, if you are using the pool sweep basket feature, then undo the connection at the pool wall and you will find that the wall filter is plugs with fin bug particles that can not make it past the wall screen. Clean and replace the hose to the wall. 2) the filter is clogged and dirty, clean the filter clean the filter compartment and replace, 3) you have an air leak allowing air to enter the pump system causing air to restrict the flow of water. Check the hose connection for leakage, check to make sure the bleeder valves are not loose or over tightened, as both will cause an air leak.

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!

We do not know where the air filter valves are


Air filter?

Remove the strainer basket cover ... fill with water ... check the gasket ... replace if questionable ... close the cover and SNUG the top down. Start the pump ... it should run just fine.

If you are sucking air, tighten the strainer basket cover a little.

Still sucking air? You will have to find the air leak. You might plug the leak with plumbers putty.

Whisperflow 1.5 pump is drawing 1/4 volume of water.


With the pump off, take out the pump basket and with your fingers
feel the front of the impeller you may have something blocking it.

Hi,

I think you have get air in the system, try to find a bellows pump or similary. Fill it with water, open the steam knob and take of the water tank, put the pump in the water inlet and press. When the water begins to flow, close the steam knob and put the water tank back.

Best regards
