Question about Hayward SAND FILTER, PRO SERIES

1 Answer

Was getting sand in my pool. Was advised that the laterals probably needed replacing. I took them out and they were good. So was told I probably needed to replace the sand. I did. Now I see sand in the site glass and in the pool. I also replaced the pressure gauge because the salt water had damaged it. I broke the site glass while doing the work and had to replace it. Hope you can tell me what I need todo now. Thanks.

You are dealing with very small fractions of fractions of an inch with the sand crystals and the lateral assembly. You cannot tell by looking at them that they are good or bad. If you are getting sand back in the pool, replace the laterals.

Be sure to fill the tank half way with water before adding the sand back in to ensure the falling sand does not damage the laterals.

A little sand in the backwash sight glass is not unusual, especially with new, unsettled sand. It should stop or get to be very minimal in a short time.

Sand shooting back in pool

If you took "Pump" apart, you wouldn't have found broken laterals. You will need to open up the "Filter" to find laterals. If sand is ending up in the pool, you either have a broken component within the filter or you have an overfilled filter tank and during backwash sand is lifted up into the valve, and upon returning valve position back to "Filter" the residual is blown back to pool via the return inlet. If this is the case that is why always follow label / owners manual directions as to Quantity of media to add. More is not necessarily always better!

When I was filtering the pool the sand from the sand filter is blowing sand into the pool

That means that you have a cracked lateral in your pool filter. You will need to replace the lateral, which should stop the sand from entering your pool through the return line.

I have an older Hayward pool filter. Is there a link to dowload instructions for replacing or adding sand to the filter?

Here is how I do it. Open the top. Open the drain on the bottom to allow the water out. Remove the plastic water difusser on the top. With a small can, scoop out the sand. When you get to the laterals, remove them for inspection. The sand below the laterals if fine, it does not need to be removed. Put the plug back in. Replace any laterals that may be broken (probably none) Fill the filter with water to about 6 inches above the laterals ... maybe more. The water will protect the laterals from the new sand as you fill the filter. It will also help the sand to pack in around the laterals. Continue filling until you are about 3 inches below the difusser that will go on the top. Make sure you don't bury the little black hose. The purpose of the little black hose is to remove the air from the filter during operation. The hose should ultimately stick up into the inside of the top (cover). I think your filter takes about 300 # of sand. Double check with your professional pool supplier where you purchase your sand. I normally will fill the filter with water before I replace the top. You may want to put on a new "O" ring too ...

This new sand should last you at least 4 to 5 years in non commercial use. After that time, you may want to replace the top 4 inches with new sand.

Thanks for your question @

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!

Hello my name is Israel and I will give you some advice. I had this problem with the same filter. It turned out to be the multiport valve. If you look at the diagram you have suggested you will noticed that even the manufacturer is now using a different valve. I think they finally noticed that they had a problem. I completely got away from a sand filter and went with a D-E filter system. It is a lot less troublesome and far superior to a sand filter. You might want to check on this. Even to replace the valve it is going to cost about $150. Good Luck.

Probably a broken or loose lateral in the bottom of the filter. Do you backwash a lot? One thing you might try if the lateral isn't too damaged is let it run for a day, vacuum the sand out of the pool and see if it stops. If this works, good. But the next time you backwash, you will have to do it again

I believe that the owners manual has a parts listing to help you distinguish the part that you will need to buy. However, if your pool filter was purchased in 1990, you are probably going to need a new filter. Most do not last over 20 years.

Sand and dirt recirculating into my pool water

Inside the filter, below the valve you will see a pipe sticking up from the sand. That pipe goes down to a bunch of 'fingers' with small slits in them to keep the sand (and dirt) in the tank and let the water out. You will probably need to replace that assembly, called the lateral assembly. The part number should be SX(numberical part of your filter model here)DA, so for example SX180DA for a S180T filter.

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)
