SOURCE: Hayward Self-Priming Pump with AO Smith 1 HP 56J

the pump must not have any air leaks in the suction side of it,, or it will just **** air and not water,,, water is very heavy you see, however i think its the impeller in the pump thats the problem,,,you should try to put water in the out let of the pump so you fill the pump with water first if its dryed out it may just wear out the impeller before it starts to **** water up, if this still dont work turn off the stop **** and strip out the pump to look at the impeller any wear on it and it will need a new one fitted
i hope this has help you, good luck

Hayward 711A13 Vari flow valve. When I push down the handle to move valve into other settings the handle does not want to relock into the next setting. I have to manually pull up un the back of the handle and tap with my hand to get spring to retract. What can I do to lubricate this sping inside?

SOURCE: I'm hearing air like sounds

Air only gets into the lines of your equipment if it enters somewhere on the suction side of the system. That means from the pump housing and strainer BACK to the pool on the inlets. Once the water passes from the impeller out the discharge of the pump it is under pressure and any leaks will result in water escaping from the line.

While your filter may or may not need work air is likely the result of failing gaskets or a seal in the pump. Replace the strainer lid ring, the pump body ring and the mechanical seal first. If there is still air look at the valve or valves in front of the pump for controlling inlet water flow...check for leaking stems or failing pipe joints.

My pool waste water outlet is blocked and when I backwash or rinse the water does not drain but overflows

A lot of times the drain line is terminating ??? who knows where?
So you won't be able to confirm water flow at end of pipe/line.
Is it clay tile pipe or soft perforated pipe?
These at times get crushed?
Either by being buried too shallow & the weight of vehicles, etc will damage/crush them.
Or tile pipe will get roots growing in them and again, water will not travel thru them.
Get a roto rooter type of service to check it out, they now have these days a snake with a camera attachment, and will be able to tell you what the problem is and provide an estimate for repair.
In the meantime, cut the waste line pipe at the multiport valve, add a secondary ball valve on the line, then just install a combo barbed fitting, like the one pictured below - so you can attach a collapsible drain hose (which comes in a roll of 25' 50' or 100'), either 1.5" or 2" , like the picture.
The combo barbed fitting will accommodate either size.

Where to connect valves

Hook a temp hose up to it, put it in water and see which way it flows. The intake is then connected to the bottom output from the pool.

Dirt passing through the filter

There is no oring from the lateral stand pipe where it plugs into the bottom of the multiport valve.

There is a gasket in the internal valve, commonly called a Spider gasket. Change that.

How to know what cycle to use or when to use filter, backwash or rinse?

during normal operation, your multiport valve should be in the "FILTER" position.

Once the pressure in the filter reaches 10psi more than what it was when the filter was clean, you should backwash. turn the pump off, press down and turn the multiport valve to backwash. turn the pump on and watch the effluent water until it goes from dirty to clean. Then place the multiport valve to the rinse position, this will rinse any remaining dirt from the top of the filter and valves so that it does not return to the pool. Once the water comes out clean, return the valve to the filter position.

Do not turn the valve while the pump is on, always make sure to turn the pump off before servicing any equipment.

When turning pump on sand shoots into pool app. two seconds.replaced diverter and lateral coponents. still does the same thing. twm 19 inch p/n 520-1910

If you don't have a manual you can download one here:
Are you sure you didn't damage laterals when adding sand. Best to have 1/4 water in filter as you add sand. Be sure o ring is in place in multiport valve that fits on downtube.Be sure down pipe is not too low to enter multiport valve. The pipe should fit snugly into the multiport valve o ring. Be sure you have correct sand (pool filter sand only) IF all this is ok, try backwashing till glass is clear. Run on rinse position for a few min. THen go back to filter and see if it still pumps in sand.

I have a hayward pump that is about 5 months old and we vaccuumed the bottom of the pool and backwashed it and now it is leakingout the waste/backwash pipe even when it is on filter mode and a little bit...

Do you have a multiport valve or a push pull valve?

Multiport should only be moved in a clockwise direction and never backward. You may want to take off the top and check the seal.

Push pull ... take the valve apart and check the "O" rings.

My filter and pump will not retain the prime after turning off. Its a pantera sand filter. I can hear an air hissing sound coming from the multi valve port

Either you have a bad spider gasket inside the multiport valve or a bad threaded fitting going into it. Check for leaks around the multiport and backwash line. You'll have to take apart the multiport valve to make sure the spider gasket is not damaged or out of place. Make sure to install the multiport valve in the same position. You can get a replacement gasket at most pool supply stores or online.
