I have a Hayward S310T2. The water is constantly cloudy and I researched that the sand may have channels not allowing proper filtration. I opened the top and tried to reach my hand to the sand and see what the condition was. It did have clumps and was very dirty so it may have had channels in the sand. My question is how far the sand should fill the tank. I could barely reach the sand with my arm all the way in, about 34". It seems it should be fuller than that.
Wayne, The S310T2 holds 500 pounds of sand. The tank will be approximately 3/4 of the way full.
Can I just purchase the filter body without the multiport valve? I need two of them. Thanks.
Yes, you can. It would be key number 6 on its parts diagram but it comes with the skirt, drain and lateral assembly. Maybe consider replacing the entire filter.

Hi, Gary. They're a few different manufacturer that has a Millenium filter that requires anywhere from 200 to 350 pounds of sand.
I have a 38k gal, 9ft deep inground pool with a Hayward SP2610X15 pump that is about 15 feet away from main drain and thinking of changing old cartridge style filter for Hayward S310T2 sand filter. Would this be a good combo?
Hi Ryan, For the pool you have explained the S310T2 would pair quite nicely with your SP2610X15 pump.
What size filter is recommended for 40000 gallon pool with 2 inch fittings?
The size of filter is going to depend on the flow rate that your filter is able to handle. What is your pump model and what is the distance from your pump to your skimmers to calculate the flow rate to properly size your filter.
Am I able to order just the handle for my valve system model S310T2?
The handle for the valve on your Hayward S310T2 is part number 4701-01.
I need to replace my filter and I'm thinking about getting the Hayward S310T. I want to make sure my current pump matches up well with my new filter. I have a 2HP Hayward Super Pump with a flow rate at 40' of head of 98 GPM. The pool has about 27,000 gallons of water. I realize the filter is probably bigger than what I need, but I feel I need to go big to match up with the pump. Will the Hayward S310T work well with my pump? Thanks!
Hello Jay- The filter I would recommend going with is the if you have anything less than 40 feet of head Sand Filter with Top Mount Valve 36" Tank - S360T2. If you have 40ft of head or more you could go with the S310T2. If you decide to go with the S310t2, I would recommend the Clearance - Sand Filter with Top Mount Valve 30 Inch Tank - 8-S310T2.
I want to install new S310T2 Top mount sand filter. The current motor size is 3HP. Is that to big?
That filter can handle 98 gallons per minute, so it will depend on what the flow rate of your current pump. I will need to know the model of your pump, not the motor, and the distance from your pump to the main drain to calculate the flow rate.
I have a Hayward S310T2 with a cracked vari-flo valve. The model of the vari-flo valve is SP071620TFV. Will a SP071621 replacement valve fit my S310T2? Thank you.
Yes, that is the replacement valve with 2" ports for that filter.
Do you sell S310 with 1 1/2" plumbing? Do not want to change anything on current system. Thanks
Hi, The S310T2 filter valve is only available with 2" ports.
I have a S310T Hayward sand filter that is about 10 years old. is the S310T2 the replacement model? Also the only reason I am replacing it is because the male fitting threads are wore out at the drain. are there any parts that can be purchased to plug the drain inside of the spout like a self tapping plug? Finally, does the model mentioned above come with the top rotating valve or is that sold separately? my valve # is SP071621
Greg, The S310T2 will replace your older filter. The filter comes with a 2" valve.
I'm looking at the s310t2 pro series sand filter. I have a 22,000 gallon pool. My pump is a 3/4 horse. It seems to be efficient enough for the cartridge filter I currently have. Is the 3/4 horse pump adequate for this sand filter model?
Hi, A 3/4 hp pump is sufficed for the S310T2 filter.
I have the following: 36,000 gallon in ground pool 1-HP Hayward pump S310T (500 pound) Sand filter Seems like a lot more filter than needed AND thinking about a Variable speed pump..... am I going to have filtering issues with reducing the GPM?
Hi Kurt, You will not have a filtering issue when the rpm's are reduced.
I know I need 500lbs But what kind? There is the sand alternative Zeobest . Silica Sand #20 high rate what if it just says #20 grade 50 lbs it doesn't say high grade
Hello Patricia, Yes 500 lbs of Silica filter sand. The superior alternative to sand - for better filtration & water quality! Start using Zeobest instead of sand in your sand filter. Using 100% natural minerals, Zeobest provides excellent water clarity, purity, and quality. Zeobest has nearly 9800 times more square footage than sand, enabling it to filter small particles down to 3 microns for exceptional water clarity - that's 10 times smaller than sand! This amazing filtering media also removes the ammonia produced from dead organic material in the water, reducing eye irritation and odor. Plus, it cuts down on chemical demand, saving you money on chemicals. Zeobest is easier to use than sand. You will only need one pound of Zeobest for every two pounds of sand your filter requires - half the effort! Since Zeobest has a greater capacity for particulates than sand, backwashing will be much less frequent.
how much sand does a S310T2 need to change the sand in the filter
Hello Patricia this filter requires Sand:500 lbs. or going with Zeosand 250 lbs
My in-ground pool holds approximately 18,000 gallons of water. What size sand filter do I need for this size pool?
There are multiple different ways that you can go with this size pool. You need to be sure that the pump model that you have has a compatible gallons per minute rating to the filter. Generally speaking without knowing the pump model or system specifications to confirm, you may want to look to use a sand filter that is approximately 3 to 3.5 sq. ft. Please review all system specifications with us or a licensed contactor to confirm that all elements of the system are compatible.
My tank split at the seam. is it possible to purchase a tank only?
Hello, It will be cheaper to replace the tank as a whole vs buying the tank by itself.
I need a decal for the top of selector value am having hard time finding one. I ask where i get my pool supplies and i was told to write hayward.
Yes we do carry this Hayward Filter Valve Label here.
Could you be so kind as to suggest whether a HAYWARD S310 TOP MOUNT FILTER would be suitable for a :- 13000-15000 galls water 2" plumbing & would it maintain enough pressure for the pop-up cleaners Thanks
Hello John - The S310T2 would be suitable for your pool. The pop-up heads are dependent upon the HP of the pump. The S310T2 will have no effect on the pop-up heads.
We have this filter. We are considering switching from chlorine to salt water pool. Will this shorten the life of the pool filter? How many years of service can we expect out of this filter? Thank you.
Good afternoon Roy. A salt system will still be a chlorine pool, it just makes it now instead of you adding it to the water. The tank will be fine and not affected any more by the addition of the salt system. The balance of all chemicals is what extends or shortens the life of your equipment. The tank should last 5-10 years, depending on the environment. The hotter or colder the weather, the harder it is on the tank material.
