XtremepowerUS 16" Above Inground Swimming Pool Sand Filter System 7-Way Multi-Port Valve Pool Filter up to 21,000 Gallons with Stand

This thing works great and doesn't leak a drop. Anyone who has problems with this probably didn't tighten everything properly. I used it for an entire season with polyester balls and my water was crystal clear the entire time.

The sand filter is the perfect size for my hot tub if it's perfectly in a small space. It is built of good quality and the price was very reasonable. It functions good and is set up easily.

Very happy with this product. I have not had it in use yet, but it appears to be exactly what we needed.

I do not recommend the XtremepowerUS 24” filter. The quality is poor. After only a couple of months of use, the threaded fittings going into the filter head started leaking. I replaced them, and within a month they were leaking again. On top of that, we purchased a stage pump at the same time, and it was dead right out of the box. Had to rate 1 star to leave review but should be 0 stars! Don’t waste your money!

Don't try to use the supplied pressure gauge with the filter! They DO NOT MATCH. Generally it's a simple and working product. I would recommend it. Some say that a 'sand filter' doesn't work effectively but I beg to differ (and that's a different topic). It filtered my 36" in-ground kidney shaped pool with a 1 hp pump in 24 hours. I used 6 bags of sand from the local pool supply (300 lbs). It had been weeks since the old filter cracked open along the bottom and utterly failed so the pool was filthy. I haven't needed to backwash it yet (since the initial flush to clean the new sand). The pressure loss through the filter is only 4 psi and the throughput is much much larger than what was happening with my old cartridge filter. In my adventures I have seen the inside of the valve and it's simple and ingenious and should last for years and years. However, it came with a pressure gauge which seems to be meant to screw into the back of the housing where the air release valve lives (on the left of the bottom picture). Even though the size and the threads match, the ABS plastic housing is NOT threaded to the NPT standard like the pressure gauge is (all the gauges are NPT like that). NPT threads are tapered and the female end, on the housing is NOT. So, it leaks. And leaks. I started with sealant and then moved to teflon tape. Leaks. I was living with that while deciding what to do. There is a clear warning label right there that, in plain English, warns against over-tightening and they really mean it because what happened next is that the pool guy came and used a tool to tighten it and cracked the housing. Duh. So, I have learned a lot about "ABS plastic welding" and you, dear reader, can know to NOT try to use that supplied pressure gauge, or any gauge, with the filter. One must mount a gauge on the inlet pipe instead.

Does anyone know what size the air diffuser tubing is ? Inside the filter connected to the lateral assembly ?

Awesome product. Bigger than I expected. Easy to install, build quality top notch, App crashed when ordering this item and I was charged twice for it. The seller and Amazon was able to resolve the issue and get me a refund in a timely manner.

I have installed dozens of sand filters in my career, usually replacing cartridge and DE filters. I have always used Pacfab or Triton, but those are pretty pricey. This one is affordable and great for smaller pools and keeps the water clearer than the cartridge filter did. It's a LOT LESS WORK to backwash this filter than it is to remove and hose off a cartridge filter. I can only guess why cartridge filters are so popular in pool stores... sand filter last for many years, no filters to buy and backwash in TWO MINUTES!!!
