Problems Centering A Sandpipe For A Hayward Pro S210T Filter

by Gaylen

I have a Hayward Pro S210T Filter.

When we opened up the pool this year and started up the filter, all seemed well.

We shocked the pool water as usual and no matter what we tried, we were unable to get the cloudy water to clear up.

Through a process of elimination, the pool technicians have advised us to change the sand as it was more than past due.

So, I removed the head assembly and started the process of emptying the sand via wet vac.

As we got close to the bottom we discovered that the standpipe was almost completely broken from the laterals assembly.

So, after removing all the sand and water, I removed the laterals assembly, carefully removed the pipe that was still glued in.

I cleaned it all, replaced the broken standpipe with a new piece of pvc 1.5" pipe, cemented it in and reassembled the standpipe and laterals unit.


As I am attempting to place the standpipe assembly back into the filter body.

I am unable to center the assembly on the bottom of the filter!

I am assuming that the standpipe should be centered in order to place the head assembly properly.

Is that a correct assumption?

If so, how do I get the laterals assembly centered in the bottom of the filter body?

There is no (apparent) slot or anything that I can see.

Thank you,


Thanks for the question Gaylen

First I would check to see if your particular filter has what's called the "Hayward S180T Folding Umbrella Lateral Assembly w/ Center Pipe".

This is for 1997 models and newer.

This is kind of a ball joint that the laterals sit in so they can be folded up to a 90 degree angle.

If so, try to place the standpipe into the filter with the laterals folded up. Then, when inside, unfold the laterals.

Next, you may have a top cap that goes onto the standpipe and fits underneath the Vari-Flo XL Control Valve.

Place the standpipe into the filter, fill with about a foot of water, then put the cap on.

This will help stabilize the pipe until you can put sand in and attach the control valve.

Always fill the filter up with some water before adding the sand.

This will help dissipate the energy of the sand directly onto the laterals.

Hope this helps and let me know how it turns out for you.

Hayward Center Pipe
by: Anonymous

The center pipe looks deformed when I disassembled to change the sand. In other words the center pipe was not round and was above the top of the filter. Is the out of roundness a issue

Thank you so much for your post. You save me approximately 60-100$$!!! by mentioning replacing the standpipe with 1-1/2" PVC. It worked perfectly!!

Centering Sand Pipe for Hayward S180T
by: Gary

When I purchased my hayward filter it came with a plastic stabilizer that fit over the top of the sandpipe to keep in line for the filter valve to fit properly onto the pipe.

I want to know if it is possible in buy a new one as I must have thrown mine away while cleaning the garage.

Thank you for your help.

Thanks for the question Gary but I'm not sure whether you can buy this particular piece from a local pool store. Your best bet would be to contact Hayward. I never had to order this piece when I had my pool route so I'm unsure if this is sold separately.
