Hayward W3C4030 SwimClear Cartridge Pool Filter, 425 Sq. Ft.

Our 23,500 gal. pool equipment suffered collapse from the 2021 Winter Storm that hit Texas over 6 weeks ago (single digits for a couple of days and no electricity). Pump seals burst, heater header assembly cracked, and every join and lever cracked... PLUS the bottom of our Hayward Filter cracked wide open. A pool sitting idle for 6 weeks becomes a chlorinated pond. Not pretty at all.Five weeks later, our pool company was able to get out to replace/fix everything but the filter. Said it would be weeks, 12 weeks or longer to get a replacement filter. Found this one on Amazon and it was delivered within 6 days. The pool tech made time and installed the filter 4 days later. The fittings were different from the original, so he had to cut the existing plumbing and redo some joins. We initially thought the tube and screen for air relief valve was not included but found those rattling around in the bottom of the filter.The filter has been running now for 48 hours with one cleaning of the cartridges so far, and will need another today. The pool is beginning to clear up and I owe it to the Hayward Filter. It has been working steady and I expect it to be just as good as the one it replaced, which worked terrific for the 10 years prior to this Valentine's Week deep freeze.

This is so much better than our old sand filter. The water is very clear and changing out the cartridges is way easier than changing out the sand on the sand filter. I would definitely recommend.

To enyone who is looking to purchase a new filter and go with cartridge one thing to keep in mind all filter manufacturers base the fitters on the square footage of water not so much on depth unless you go over 40 k gal the gallon are how long you need to run the pump depending on the pump you have take in to consideration when you purchase a pump better oversized than understanding the clear the water and chemically balanced water the longer the equipment and the finish will last and less maintenance costs. Properly balance pools less wear and tear on everything. Pressure vac are better do that vac debris don't go in to filter down fault need to empty vac head lot easier than to clean filter more often.

Had this for a week. Works great. Cleared algae at beginning. For some reason pressure went DOWN. I thought pressure goes UP when the filter is dirty. So I thought my pump was broken. But my pool guy said the filter is clogged. We washed the cartridges and pressure when back up. Pool was clear within a day after.

Had to do a little plumbing work as the old ports were at the top of the filter and the new ports are in the middle of the filter. Also, the plumbing for my pool and the old filter uses 1 1/2" pipes. The ports from this filter use 2" pipes. If you have that issue, you will need to pick up some supplies to increase/reduce the pipe size to fit the new filter. It wasn't super complicated to do the physical work, but the planning might be a bit challenging. Make sure you have a clear plan of how the pipes need to go before starting your work. I would suggest hiring a plumber if you do not feel confident and can afford to do so.That said, it works GREAT! We had a sand filter with super cloudy water. I worked on it for weeks trying to clear it up with chemicals. No good. Changed out the filter and overnight, the pool was crystal clear. It works amazing!The only issue I saw was that on one of the ports, a very very small piece of plastic was chipped off the end. I do not believe it will affect how the filter works at all. I believe this was a fluke and possibly a handling issue, but not any fault of the vendor.

Very simple to fit and plumb in, about the same footprint as the old sand filter. So much more efficient, just does a better job for sure. And knowing that the changeout of the filter cartridges will be so much easier than dealing with that old sand filter is worth the cost of admission. Thank you!

This filter leaks, no matter what you do , I honestly believe it has a design flaw on the lid and seal because it does not seal ...leaks constantly no matter what I do to remedy that , I am about to throw this pos away!

I had problems, but I want to start off saying that my family has had nothing but positive experiences with Hayward(the company not the city). I was replacing the C3020 with the C3030. I broke the manifold on my old filter from purchasing filters that were too small, that was my fault, but it was about time to replace the whole thing anyway. Called Leslies…once I hung up the phone with them, I immediately went on amazon and paid for the item and was being delivered Monday morning(did this on Saturday).I saw that the pressure gauge was cracked, but was hoping it would still work, it didn’t, but I know Hayward will send another one(did I mention they are great?). That wasn’t the biggest problem. The biggest problems were the inlet and outlet were about ¾ of an inch higher that the C3020, the union connectors were now 2 ½ inch and the C3030 was a bit fatter than the C3020. The ¾ of inch height difference was fixed by a piece of old growth redwood siding placed underneath the pump. Because the C3030 is a little bigger you can see I had to add a few inches of pipe, that wasn’t difficult either, though finding the pieces to connect the 2 ½ inch union connectors to the original 2 inch pipe was not fun. Home Depot does not carry 2 ½ inch connectors, at least not at our local store. So went to a plumbing supply store in the next town over. Got what I needed put everything together and of course it leaked. I created 16 new connections and there was only two that I really cared about and of course it was the union connection for the inlet that was leaking.So I guess I will be buying another union connector on amazon, luckily I used a 2 inch threaded pipe fitting at the union connection for this exact reason. Should be an easy fix, just frustrating, and already left a message with Hayward about the pressure gauge, I am sure I will hear back from them soon.Ran pump for 24 hours and you can see the results….BEAUTIFUL!
