Review: Good filter and value for the money - I purchased this filter to replace my existing cartridge filter. The new filter cartridge was going to cost over $100, so I decided to spend a little more and get a backwashable sand filter for my 10'x16' KD above ground pool. Available w/ desertcart Prime, it was at my door in two days w/ free shipping. Well packaged and complete. Can't beat that. After getting it plumbed in, I stood back and admired my professional looking plumbing job. I started the pump and the pool got pretty cloudy and after a few hours the valve popped up and began shooting water out of the discharge port. As you can imagine, I was pretty PO'd. I remember reading one of the other reviews which had mentioned just this problem with this valve. "I knew it", I said to myself. I sat down full of anger and emailed Hayward Pool Products, and was prepared to be blown off, as the same review had mentioned. To my surprise, early the next day my phone rang. I did not answer because I didn't recognize the number. It was Hayward's service dept calling about my issue. How's that for a quick response? It did take me another two days of phone tag with Hayward before I actually spoke with a rep. He was very nice and professional, and asked me if I was home and could take a look at the filter. When I did, he asked me very nicely to follow the plumbing line from the pump to the filter. As soon as I did, my jaw dropped and I felt like a complete idiot. I had plumbed the pump to the discharge port, and the intake to the return to the pool. Completely backwards!! Apparently I am not the only one to do this, and I suspect that was the problem in the earlier review. The Hayward rep was very nice and said this happens sometimes. I would not have blamed him if he had laughed at me. After redoing the plumbing, this time correctly, the pump works fine and has done an admirable job of keeping my pool water sparkling clean. It was a bit of a pain to get all the sand vacuumed up, but after I did, all is well. The point of this long winded review is that this is a quality product, it works well and as advertised, and my impression of Hayward's service is nothing but outstanding. Just make double sure of your plumbing connections, or have it installed by a professional. I refuse to pay someone to do something that I can do myself, but this requires extra dilligence where necessary. I hope this helps. Review: Works beautifully and fit right in place from the existing filter - It's a good value for the money as it cost the same as the box stores. Do. It fit right in place and my existing hoses buttoned right up to it. ## Features - The Hayward ProSeries 18-Inch Above-Ground Pool Filter features durable corrosion-proof materials for dependable all-weather performance - Precision-engineered umbrella-fold self-cleaning lateral system provides efficient flow and evenly distributed water for totally balanced backwashing and long-lasting performance - 7-position VariFlo valve provides maximum flow at lower pressure drop - Large pressure sand/water drain for rapid winterizing or servicing - Integral top diffuser ensures even distribution of water over the entire sand bed for maximum use of the filtration area ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07SS48CCX | | Best Sellers Rank | #87,282 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #37 in Sand Pool Filters | | Customer Reviews | 4.6 4.6 out of 5 stars (1,793) | | Item Weight | 29 pounds | | Item model number | W3S180T | | Manufacturer | Hayward | | Product Dimensions | 20.3 x 20.3 x 36.4 inches | ## Images ![Hayward W3S180T ProSeries Sand Filter, 18 In., Top-Mount for Above-Ground Pools - Image 1](https://m.media-amazon.com/images/I/61wJicDQ-vL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good filter and value for the money *by T***O on March 27, 2012* I purchased this filter to replace my existing cartridge filter.

It fit right in place and my existing hoses buttoned right up to it. ### ⭐⭐⭐⭐⭐ Very good filter, very good price *by T***E on July 1, 2017* Bought this to replace my exact filter that failed. It turned out more cost effective ($123.99) to replace the whole filter than to just buy the valve that went bad ($89.99) and other parts that "may" be bad in the old. I also purchased the Hayward fittings for my hoses. I purchased the sand (100 lbs) #20 silica at ACE which was 1/2 the price of anything offered on Amazon. Installed easy. It came with the filter tank with the lateral assembly already inside, the base for the filter and an add on base for your pool pump. The valve and brace was packaged separately. The valve fittings + nylon tape (purchased separately) were easy to screw in and only needed 1 tight screw with a wrench. I watched a Youtube video to be sure about installation and new use. I read the reviews and people complaining about the still cloudy pool should read the instructions carefully and watch the videos on Youtube. I first rinsed the the sand, then back-washed the filter (as directed) before operating in the pool. My above ground pool was greenish and cloudy from the failing filter and 3 days without a filter. I shocked the pool over 2 days & added clarifiyer. It took a full day for me to run the filter, back wash it at least 3 times to get the dead algae out of the sand from the filtering water. The pool is now crystal clear. The valve is much easier to move position to position since my old valve must have had a bad spider gasket that is built into the valve. ## Frequently Bought Together - Hayward W3S180T ProSeries Sand Filter, 18 In., Top-Mount for Above-Ground Pools - U.S. Pool Supply Replacement Universal Combo Hose Adapter, 1-1/4" or 1-1/2", 3 Pack - Fits Above-Ground Pool Pump, Filter, Skimmer - Compatible with Hayward SPX1091Z7 or SPX1091Z4, Swimming Pool - Hayward W3SP1580X15 Power Flo Pool Pump, 1.5 HP --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/202000956-hayward-w3s180t-proseries-sand-filter-18-in-top-mount-above](https://www.desertcart.com.cy/products/202000956-hayward-w3s180t-proseries-sand-filter-18-in-top-mount-above) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-25*
