SOURCE: Pool pump will not fill back up

It sounds like you are sucking air into the pump. Make sure strainer baskets and pump baskets are clear, and the valves are in the right position. Also check the water level in the pool, and make sure that the pump is not sucking the skimmer dry. Next try lubricating the gasket on the pump lid, or if it is in bad shape (flattened/cracking) replace it. If this does not solve the problem put silicone around the inlet to the pump (silicone is a temporary fix that could last days or months--for best results replumb with teflon tape and sealant). If all that fails you could have debris stuck in the impeller.

SOURCE: NOT FILTERING, NO SUCTION, CHANGE SAND,,,SINCE DAY ONE..WRONG HP?

You are correct. Your lines are extremely small for this system and the pump is to small for this system. You are going to have to do a total upgrade. from the pump to all the lines. I know this is bad news, but it is a common problem for system that where put in more then 10 years ago

SOURCE: 1/2hp Hayward Pump for existing inground pool

you will be fine with the 1/2hp. The Hayward will move quite a bit of water as well. It may not move as much water as the 3/4hp but it's very close and the 1/2hp will cost a little less to operate so if anything, you may just have to run it for one additional hour per day to compensate. You will be surprised how much water a 1/2hp will move. The only issue with smaller pumps is if you have pop-up cleaner heads or a suction driven automatic cleaner such as a kreepy krauly, however, if a 3/4hp will run it, a 1/2hp will run it as well. You can install a larger motor on the super pump but it will not move more water unless you upgrade the impeller as well. Just make sure you don't use a bigger impeller than what the motor is rated for because it will strain the motor and cause it to overheat. Hope this helps.

SOURCE: How to open pool, fill sand filter with water?

I happen to have a copy of the users manual for this pool filter. These are the instructions for operating your filter.

1. Be sure correct amount of filter sand media is in tank and
that all connections have been made and are secure.
2. Depress Vari-Flo control valve handle and rotate to
BACKWASH* position. (To prevent damage to control valve
seal, always depress handle before turning.)
3. Prime and start pump according to pump instructions (be
sure all suction and return lines are open), allowing the filter
tank to fill with water.
WARNING: ALL SUCTION AND
DISCHARGE VALVES MUST BE OPEN WHEN
STARTING THE SYSTEM. FAILURE TO DO
SO COULD CAUSE SEVERE PERSONAL
INJURY.
Once water flow is steady out the waste line, run the pump for
at least 2 minutes. The initial back-washing of the filter is
recommended to remove any impurities or fine sand particles
in the sand media.
4. Turn pump off and set valve to RINSE position. Start pump
and operate until water in sight glass is clear—about 1/2 to 1
minute. Turn pump off, set valve to FILTER position and
restart pump. Your filter is now operating in the normal filter
mode, filtering particles from the pool water.
5. Adjust pool suction and return valves to achieve desired
flow. Check system and filter for water leaks and tighten
connections, bolts, nuts, as required.
6. Note the initial pressure gauge reading when the filter is
clean. (It will vary from pool to pool depending upon the
pump and general piping system). As the filter removes dirt
and impurities from the pool water, the accumulation in the
filter will cause the pressure to rise and flow to diminish.
When the pressure gauge reading is 8-10 PSI (0.55-0.69
BAR) higher than the initial "clean" pressure you noted, it is
time to backwash (clean) the filter (see BACKWASH under
Filter Control Valve Functions.)

SOURCE: Dial a flow question

Ok the first on the PSV valve. the 1/2 position should really be 1+2. You have two linlets to your pump. One from the skimmer and one from the main drain in the floor of the pool. When you select port 1 it will be one or the other perhaps 1 would be skimmer and 2 would main drain. You can select one and see if the flow stops in the skimmer. That will tell you which is which, depends on how it was plumbed. Position 1+2 combines the two flows. I normally select both, If my pool gets a lot of grass and leaves, I select skimmer only or when I vacuum. I select main drain only when there is more debris at the bottom. OK recirc is only recirculating within the piping system bypassing the filter. You can dowload a complete manual of your filter and components from www.haywardnet.com. Green water: Ok your chemicals are right? Free Chlorine, total chlorine? hardness, calcium, pH, alkalinity? Well most pool companies want you to buy some algaecide and that can't hurt, but I'd shock your pool if it's dark green I'd put it 4-6 gallons of liquid chlorine, if its light green 2-4 gallons. This is when I'd use recirculate. Allow this to mix without filtering for a couple of hours. Turn the pump off and allow to set overnight. In the morning you should have much clearer water, with green slime sitting on the bottom. Vacuum this to waste very gently so as not to remix algee.IF this doesn't work you'll need som floculant and repeat the opeation folling the directions on the floculant Restart filter, keep chlorine level high above 5-10ppm for a day or two and keep filtering. If it is still cloudy now,add some filter aid. In hot weather, don't let that free level go below 4ppm. Don't allow anyone to swim while chlorene level is high. Be sure to us test strips that indicate free and total chlorine.

Lose press on retrn to pool using Hayward S166t with brand new veri flow pump attached. I back wash and pressure restored is excellent but within 15 or twenty min drops off again.


what is the water like?
Dirty? Green? Murky? Cloudy?
Something is clogging the filter!

Let me ask this, you said: "Pressure drops Off" ???
Do you have a pressure guage on the filter?
Does the pressure increase? Or does it Decrease?
This will be an important piece of information!!!!
  • If pressure increases on the pressure gauge...
    • then filter is working and filtering out dirt and filter is clogging up.
  • If pressure decreases on the filters pressure gauge,
    • then the basket, or literally anything that is decreasing or stopping the water from getting to the pump, or more precisely to the internal impeller of the pump!
Most commonly - plugged impeller, baskets need to be checked, enough water in pool? etc.

Hurlcon ctx 2hp pump troubleshoot


It sounds like you have a suction leak. What's odd it that it works for 2 hours then loses prime. I don't think it would be related to the air temperature. Check out the pump basket lid o-ring to make sure it is in good condition and properly lubed (this is a very common cause of suction problems).

Also check your water level to make sure it's high enough. Any valves on the suction side of the pump may also be suspect. Good luck with it.

Pentair Whisper Flow 2hp pump appears to not **** as much water as before. Filter basket recently broke and allowed small leaves to get sucked up by the motor. Could this be the reason for the loss of...


Yes, If the debris you speak of got past the filter basket, it can clog the impeller. If the impeller is clogged, it wont pump water. Simply remove the 6 bolts on the pump end, then remove the diffuser with a 3/32 hex wrench, then clean the impeller. Its very easy, and very important that this get done every 6 months in an outdoor pool with trees surrounding it.

Also, the filter basket should last a long time, if this is breaking on you, make sure your water chemistry is in check. Agressive water can cause lots of damage and cost lots of money.

If you still have bad flow after this fix, replace the shaft seal.

Pump will not stay running. motor gets warm. motor shuts down after running for about 10 to 20 seconds.


Check the voltage at the pump while its running. If the electric feed line is too long for the guage wire,
voltage drop will cause the motor to overheat and switch off.

Help low pressure in pool pump and filter


I can relate so well to your problem. My pool is surrounded by pines and deodora trees... all the needles seem to find their way through the baskets, strainers and into the inlet of the pump. It became a daily routine of having to reach into the inlet and clean the debris if I wanted a filtered pool.
Here' s a solution that will work!
Purchase an extra debris scoop ...the kind you put on the pole and scoop debris from the bottom of the pool.
Cut the net out of the frame and wrap the netting around the skimmer's debris basket and secure it with an oversized rubber band or zip ties, then replace the basket back in the skimmer.
Your skimmer will keep the debris out of the pump!
This will make a world of difference in your pump's pressure!
Give it a try and see if you're not working better!

I have 1 and 1/2 horsepower sprinkler pump that wont prime. As soon as the end piece fills, it will empty if I open the end to the sprinkler.


I don't know what is your system set up. However, the system set up should be the following;
1. Your 1-1/2HP sprinkler pump must be installed at
a fix location nearest the water source. (Complete
with power and plumbing lines.)
2. At the end of the suction line is a vertical check
valve with strainer.
3. The suction pipeline must be connected to the
suction port of the pump.
4. At the discharge port, a flow control valve tee must
be installed. The flow control valve tee top is
covered with a plug, which serves as the priming
port when opened.
5. After the flow control valve, connect a short nipple
so that you can put a gate valve to stop the water
flow or allow the water to flow. You may connect
a pressure tank at this point or you may connect
the pressure hose going to the sprinkler.
6. To prime the pump, open the plug at the flow
control top. Fill it full with water, replace the
priming port plug.
7. Turn the flow control valve to full closed position.
8. From full close position, switch the power on.
9. The pump now run on and off due the pressure
switch setting. Slowly open the flow control valve
such that the water pressure remains steady.
10. Take note of the pressure.
11. Shut the power off, and connect the sprinkler
pump hose.
12. Put the power back on, and allow the pump to
run with the sprinkler.

Under this set up, you can run the sprinklers when your pump is running. Hope this will solve problem.
