Product details

The Hayward SX230DA is the lateral assembly for SandMaster and Pro Series sand filters, supplied complete with the center pipe. It is the genuine Hayward part.

What the laterals do

The laterals sit at the bottom of the tank under the sand bed. They are slotted so water can pass through while the sand stays behind, and they feed everything back up the center pipe to the valve. That makes them the only thing standing between your sand and your pool.

When to replace them

Sand appearing in the pool, usually as a fine trail spreading out from the returns, is the classic sign that a lateral has cracked. Because the laterals all age at the same rate, replacing the assembly as a unit is more sensible than chasing one broken arm. Check the model of your filter against the fitment list before ordering.

Questions and answers

What people ask about this product, answered by our pool techs.

Does the center pipe come with it?
Yes. SX230DA is the lateral assembly complete with the center pipe.
Which filters does it fit?
It is listed for the Hayward SandMaster SM1700T, SM1900T and SM2300T, and for Pro Series side mount S-311SX, 311SXV and 360SX and Pro Series top mount sand filters.
Why is sand blowing back into my pool?
A cracked or split lateral is the usual cause. The laterals are the screens that hold sand in the tank, and once one fails the sand has a path straight to the returns.
Is this a genuine Hayward part?
Yes. It is the Hayward OEM assembly, part number SX230DA.
