Hayward S200 sand filter. How do I install the Bottom Drain Screen?

I have an older Hayward S200 sand filter. I'm replacing the bottom half of the tank because of leaks from some hairline cracks where the bulkhead fittings pass through.

I can't figure out how the bottom drain screen attaches to the new tank. On my old tank, it seems like it was glued in but that doesn't seem right.

Here's the parts in question:
  • SX200AA1T - FILTER TANK W/DRAIN -TAUPE-
  • SX200H - BOTTOM DRAIN SCREEN
This site has good pictures of the drain screen for reference...


If anyone needs pictures of inside of the tank, let me know and I'll update this post.

SMONET Model CR6 Pro Review

Well... I am here to post an update. I am on my 4th unit since my original purchase in July, 2024. It came with a one year warrenty. I do have to say that the customer service is outstanding. I email them the issue, send them a short video showing the issue, send them a pic of the serial number and they send me out a new unit. All communication is through email, and is 24 hour response time since they are in China. It has been a different issue with each unit. Can't remember the issue with each one, but one unit would no longer charge, and another unit the one track would not turn. So the units are only lasting about 2 - 2.5 months. But when they do run, they do a pretty decent job. Hope my review and update helps others in the quest for the holy grail of pool cleaners!

ok, after much research, i still need help knowing which UV system to purchase/install

There's many different ways to do oxidation processes - straight ozone injection, UV light, peroxide with a catalyst (typically iron chloride), UV + peroxide or MPS, etc., etc. UV light is oftentimes used to generate ozone gas in a tube which is then injected into a water stream using a Venturi adapter. Corona discharge (CD) is another method for generating ozone. CD is typically cheaper to implement but both methods suffer from poor efficiency because they use air-sourced oxygen to generate ozone. Unfortunately, air is mostly nitrogen and it often contains a lot of water vapor which is a poison to the ozone generation process. Real commercial ozone generators use concentrated oxygen streams that are free of CO2 and water vapor.

All AOP's will suffer from chemical inefficiencies because recreational water typically has very high bicarbonate levels (the main component of the measured TA) and bicarbonate is another scavenger of oxidative radicals.

I would stick with a simple UV setup and see how it works for you. Ozone in an indoor pool setting is not really a good idea unless you have a contact tank and a way of off gassing the ozone through a carbon filter to avoid respiratory issues.

Attach pergola to patio -- worried about gas lines under patio

Do this. When the guy comes out just tell him what you’re doing and he’ll mark out the gas line location. Concrete tends to be 4”~ deep and gas lines are supposed to be deeper, but the drill bit doesn’t always stop at the required depth.
My thoughts at the moment are to construct the pergola (without attaching it to the concrete decking) and then call 811 out so they can get an accurate look at where I want to place the pergola.

Mixed Instructions - VS Pump & SWG

I tried to research how the system works on the CircuPool site and left with more questions than answers. I would be very surprised if it did not allow the ability to set SWG schedules through the app, but I can't find confirmation that it does. Can you link SWG system you are gonna install...


this it the one! what's ridiculous is it's not even on circupool's site...but i bought it from discount salt pool...so was i scammed? very odd if you ask me.

Mixed Instructions - VS Pump & SWG

I'd wire the pump directly to a GCFI breaker.
My *OPION*, the only way to know the pump is not running is to have a Current Sensing Relay (which is what I have...)

Review this again, particularly,
A Variable Speed pump (VS) should have continuous power and not be connected to a timer. The pump runtime should be controlled by its internal control panel and clock. A separate mechanical timer can control the SWG. Care must then be taken for the SWG timer to turn on 15 minutes after the pump begins running and SWG power off before the pump turns off. This can become a problem when house power is lost, and the pump retains the proper time while the mechanical timer does not.
tell me more about the current sensing relay and how that works... please :)

Pump Union Help

Thanks for your reply. I think I'm in luck with the union size as the Amazon order is a kit so it comes with it and is designed for fitting my Superflo pump.

Question: How long do I need to let the purple PVC glue cure before turning the pump on?

Here is a pic the kit I ordered. It comes with 2 sets. View attachment 643478
PVC glue is not purple, that is PVC primer. If you get a good "blue" glue properly and use it with a primer, it will be ready to use faster than you can complete the repair and install it to the pump. If it is a warm day, give it 5 minutes, if it makes you less anxious. If cold, 10. Even a clear glue will set quickly. Just be sure to use enough to completely cover the entire area that is to be in contact with the pipe and fitting and use it on both surfaces. Since that is on the suction side, it is far less likely to leak than if it were on the outlet of the pump.

Help Wiring New Pump

Yes. Hard to read, but it looks like the terminal top right is high speed (circuit 1 on the Intermatic) and the top left is low (circuit 2 on the Intermatic). If it is reversed, just move the wires.
The "common" appears to be the center terminal of that board. It would normally be the wire that goes to the A terminal on a Century 2-speed pump motor, which is what you probably have now.
You won't need to use the terminals that the diagram shows for the "line" wires except for the ground terminal.
A picture of the timer with the insulator removed would help determine which wire is going to the common from the timer.
I just posted it!

Can I just bypass the switch and wire it directly to the area I circled?

Hayward OmniHub Install Not Recognizing Smart Relay

Just wanted to update, incase anyone else runs into the same issue.

After a little back and forth with Hayward support and sending them proof of purchase, and pictures of the message and wiring, they decided to replace the Smart Relay under warranty. Received the new one late last week and got it replaced this weekend. Everything is working perfectly now. Woo Hoo!

Pump Basket has air trapped - most of the time.

I run in GPM mode most of the time. I use RPM mode on the quick clean option set to calculated 3K rpm and I use that value to check DE filter pressure. With clean filter and 3K I have 20 psi at the filter. The air is gone when I have to booster on but returns in a couple of hours after I turn off the booster even running at 3K rpm.
The pump is only a few weeks old. I did remove and lube up the two drain plugs on the pump as well and took out the lid o-ring and cleaned/lubed it. The lid is different in that the clear part appears to be an insert inside of the ring that tightens the lid. It has an o-ring in it too, but I can't see how it would come out.
Is there any way that too large of a pump could be the issue? I was a 1.5 single speed Challenger and replaced with 3hp VSF. Pipe is 1.5" for the most part.
Are you able to continually expel air from the filter at the air relief valve? Do it once, come back a few minutes later and try again. Is it a lot or just a quick spurt? Seeing no air in the pot used to be the standard to judge by. Now, with VSPs, it isn't. You get used to it.
My VSP will, on a rare occasion, have no air visible in the pot, usually right after a filter cleaning. Most of the time it does show what appears to be some. Yet, I am seldom able to get more than a quick spray of air from the filter, even at low speeds.
I know my pool equipment, like most eventually, has a small leak somewhere that allows the filter to drain each day after the pump shuts off. There is never water anywhere. Some leaks will allow air in but are small enough to not allow water out.

Help Wiring New Pump

Looks like the pump speed can only be set by the switch on the pump. To power your new pump it just needs two hot wires (250V between them) and a ground. Not sure what your current controller is, but I would bet if you looked for the install manual for it there would be instructions on connecting it to a single speed 250V pump.
