Question about Hayward SAND FILTER, PRO SERIES

My pool's sand filter is leaking at the cap. I have tried replacing the cap, but it still drips. Do I need to replace the filter tank now or is there something else I can do to seal the threads?

Put the cap back on and get a two part apoxy that seals leaks more affectionatley known as pool puddy. surround the edge of the lid to the tank. it drys really hard and will seal the leak. use water when combining the two parts . it has the consistancy of play doe but dries like rock. Take equal parts and roll it in your hands like making a hamburger. then roll it and strecth it like thich spegetti and surround the lid against the tank.

Trying to put pump system together. Do we remove the drain screen before adding sand?


Our terminology is not coinciding...
Follow these steps...
  • 1st - understand that a pump moves water thru your system.
  • A filter cleans your water
Sand does not go into a pump.
sand goes into the filter.
  • when adding sand into filter tank, top valve is not in place, you Need to first add water, to cover the laterals at bottom
  • Then PLACE a cap or something/anything, over the stand pipe, so NO sand goes into that pipe! IMPORTANT! Begin to add sand.
    • Do this slowly, being very careful to NOT disturb position of stand pipe! Do NOT Lift it or allow it to rise up! Keep it centered!!
  • Add required amount of sand
  • Remove stand pipe cover/cap that placed
  • Install valve onto tank
  • Complete plumbing in-out of the valve
    • Presuming you have the plumbing complete from and to pool?
    • Pool suction port to front of pump. Out of pump into 'Pump' port of filter valve
    • Out of 'Return' port to pool
GOOD LUCK

Hayward sand s166t. leaking from bottom


Are you sure it is leaking from a spot "Originating" at the bottom? Many times this is what is seen, but the water is actually traveling down the side.

If at the bottom, you either have a cracked tank, or the drain cap is loose, missing the cap gasket or it is on "Cross Threaded"?

But... most likely from experience, it leaking at the valve clamp.

Sand Leaking From Filter into Pool. When my filter is running I am experiencing sand in the bottom of my pool from the filter. What can be causing that?


There is only one thing that can cause sand to come back into the pool from a sand filter. The internal assembly, called the lateral assembly, is either cracked or broken. This is an easy fix and should cost you around $70 to replace the whole thing. You need to unscrew the bottom drain cap on the filter to remove the water in the tank. Then, remove the multiport valve on top of the filter. Take a shop vac and remove the sand in the filter. If the sand hasn't been replaced in the last 3-5 years, this would be a great time to do that since you already have the sand out anyway. Then, remove the lateral assembly and inspect the entire thing. After you replace the lateral assembly, you'll need to fill the sand filter tank 1/2 full of water before adding fresh sand. This is done to cushion the laterals from the weight of the sand. Cover the hole in the top of the lateral assembly pipe with a cup or duct tape to prevent any sand from getting inside the pipe (the sand will come out into the pool if it gets into the pipe). Fill the tank 3/4 full of pool filter sand. Make sure it is genuine silica pool filter sand from a pool company. A lot of big box and home improvement stores sell play sand as filter sand. This will cause you more problems!

Sand and debris isn't being filtered out and comes back into the pool via return water


The lateral assembly in the bottom of the sand bad inside the filter is broken. You may not even see damage on it when replacing it but it is the problem. Replace the sand while you are at it. Be sure to fill the tank half-way with water before adding sand back into the filter. Also be sure to cap the top of the lateral assembly so sand doesn't get into the standpipe that inserts into the bottom of the valve.

I dont kno how to operate to open the pool. Please help


You can go to the Hayward web site and download the manual and parts list. They also will trouble shoot basic issues over the phone. Here is the manual website: http://www.hayward-pool.com/prd/In-Ground-Pool-Manuals_10201_10551_14502_-1_17009__I.htm
Here is the main page for help. You will need to register to get a live person. http://www.haywardnet.com/contactus/
Air leaks are the enemy here. Check all unions and valves. Also, if you are handy you can replace the impeller and seal on the motor. If you are getting sand blown into the pool, you will need to remove the sand and inspect the fingers inside the tank. Replace sand carefully so as to not damage fingers. If the pump will not stay primed, recheck for air leaks. That should be enough to get you started. Download everything and study it, then call tech support after you have tried the basics. Good Luck!

Sand coming into pool from newly installed 220 hayward sand filter. It was recommended by the local pool distributor to add a 50 pound bag of gravel to the bottom and then 200 pounds of #20 sand. Should...


The problem was you didn't fill the tank with water or added the gravel to fast and now the lateral assembly is broken and letting sand into the pool. You'll need to empty the tank and replace the laterals. Add gravel slowly after you fill the tank half-way with water first.

My husband changed the sand in our Hayward Sand filter for our pool and now it leakes sand into the pool. What's wrong?


Thank you for posting your question here on Fixya.com.

He broke the lateral assembly in the process and it will need to be replaced. You'll need to know the model number of the filter to get one. Then remove the sand, replace the assembly, fill the tank ~1/2 way with water, slowly add the sand back into the tank and replace the valve.

Sand in my waste water


O-rings or gasket are replaced to stop leaks, so that wouldn't have helped you.

It could be one of two things; either the white PCV-like pipe in the filter tank is cracked OR some of the laterals at the very bottom of the tank, under the sand, has melted. A whole new underdrain assembly is usually $70.

Sand is in pool after backwash


A little sand is normal, called a puff back. Anything more then a good pinch of sand is a problem If its a lot of sand you can check the following.
1. O-ring in side the filter valve when standpipe inserts is intact. Make sure that standpipe is not cracked and seats well into valve.
2. check spyder gasket inside filter head. (looks like a wagon wheel) if it is loose or is pulling up it will need to replaced or re-siliconed. A good indication of this being the problem is if water is leaking from backwash port.
3. Check hoses to make sure that the to pool, to pump conections have not been reversed, if this was case you would get a lotta sand into pool. (can empty tank)
