Review: Top Notch Product - I recently purchased the iSpring WSPARJ-BP automated spin-down filter - see after installation image. The item arrived in good condition with all parts securely packed. It came with a 50 micron filter which should be adequate, based on an initial two-week evaluation. I live in a rural area which is underlain by alternating beds of thin limestone and shale. Water for the house and property is drawn from a hillside spring box. So the problem was excessive silt and fine sands plugging the 4.5-inch by 20-inch string-bound Pentek water filter over a short period of time. The result was lower household water pressure and lower water faucet flow. Changing the Pentek filter element on a short schedule was both tedious and costly. I needed to improve the filter life of the Pentek filter. Over the last couple weeks I have tested the iSpring WSPARJ-BP automated spin-down filter and it seems to work properly. I left the automatic settings in their default mode. I have used the auto-push-button flush mode for testing. I am very happy with the unit. Many thanks to customer service at iSpring for their timely and professional help during installation of the unit. Pros: 1) Works as promised; 2) a cost effective solution; 3) a good value for the money, well built; 4) helpful, responsive and professional customer service; 5) fairly simple installation, no leaks encountered; 6) automated and scheduled operation is easily programmed via installation instructions; 7) batteries included for battery-only operation, 8) capable of 110v operation, power supply included, 9) extra parts are included to convert to a fully manual filter unit operation, if desired. Cons: 1) The screws included for mounting the filter to the wall are inferior grade phillips-head and are too “small-headed” for the mounting bracket holes, no washers are included; 2) screws for attaching the filter head to the mounting bracket are difficult to use (think tiny short screws, tightly threaded and of the “flathead-type” design); 3) the bypass handle is difficult to shift from one mode to another; 4) the filter wrench can be used to help shift the bypass handle mode-to-mode but this technique is only illustrated at the seller’s website and not in the .pdf online installation/user manual; 5) the plastic drain hose came permanently kinked in two places - see image (iSpring customer service replaced it immediately when notified of the issue); 6) the filter body and filter head were way too tightly joined upon receipt of the unit and it was difficult to separate the two without first mounting the entire unit and wrenching it apart; 7) no instructions are given regarding the filter housing rubber o-ring used to seal the unit - for example: a] do not over tighten the filter body and crush the rubber o-ring, hand tight plus 1/8 to1/4 turn is sufficient to prevent leaks and o-ring damage, b] always apply a thin layer of silicone grease on the rubber o-ring to help seal it, c] maintain the o-ring by cleaning and reapplication of silicone grease during assembly/reassembly of the filter unit, d] expected end-of-service life for the o-ring ?, e] where can I order a replacement o-ring ?; 8) the current .pdf installation/user instructions, Version 01/2023, available online, are incomplete and need revision. Suggestions to iSpring: 1) Replace all installation screws with hardened hex-head design for easier sturdier installation; 2) coil drain hose for packaging; 3) ship filter loosely fitted so customer can inspect the internals and disassemble it for easier mounting; 4) update Version 01/2023 online Installation & User Manual .pdf
Review: Outstanding customer service! And the Cadillac of sediment filters (but I need a 50 micron filter) - TLDR, fantastic customer service and solid product. You won't regret purchasing this filter. I bought this item from an desertcart warehouse deal. I received the filter and found the automatic module that opens the ball valve at the bottom of the filter housing was defective. When installed, the module wasn't engaging the ball valve. I was able to get the original module to work by pulling out of the white shaft that engages the ball valve. But the gears inside ended up being overly noisy which didn't inspire confidence, and I was concerned about the warranty. I'm guessing this is why it was returned, as the filter assembly itself never had any water run through it. Side note: Shame on desertcart for reselling a product that had a known problem, you folks need to do better on these warehouse deals. So I called the customer service number in hopes to resolve the issue. A robot answers the call first, which immediately had me thinking I was going to wait a long time and be connected to someone on the other side of the globe or some AI bot. I was surprised and happy when a real life human picked up the phone after waiting less than a minute, AND that person was based in the USA. I connected with Nick at the customer service line. He listened to my concern and advised me NOT to return the unit to desertcart. Doing so would just cause the unit to be resold (again), and the next person would run into the same problem I was having. After a brief call Nick advised me to email him a description of the concern along with some pictures for documentation and proof that I was the purchaser. He emailed back and told me he was sending a new module. Amazing customer service right there! Most companies would not take the proactive stance, but Nick and ISpring absolutely care about their customers. He didn't want to leave me with a questionable part after buying a brand new filter. Top notch customer service and they've absolutely earned my future business. Now, as far as the filter goes, this is an extremely well built sediment filter. It's the Cadillac of sediment filters! I have previously installed one of the smaller sediment filters, which works well, but also clogs quickly. I wanted to try this unit to save me the hassle of having to walk out to the pump house and manually clean it twice a day. This filter is large, and that extra surface area means more filtering and less clogging. Along with the automatic module, it makes the sediment filter as maintenance free as it can be. My only regret was not going with a 50 or micron filter. The 200 does catch some, but for my application I think the 50 micron (or maybe the 100?) would have worked better, especially considering the much larger surface area and the automatic flush which can be programmed to flush frequently. But how are you to know before running and trying to see what level of filtration works best? Right now my next filter in line is a 5 micron, and that's picking up a lot of sediment that is passing through the 200. Two things I would design differently if it were me. One, make a filter wrench that goes over the black part at the bottom without having to remove the black piece or the auto module. Having to remove all of that to service the filter is bothersome. Two, put the power plug on the side of the auto module instead of the back so that you don't have to remove the module to remove the power cord. Fwiw, my work around is to loosely leave the filter wrench on the housing so I don't have to mess with taking off the stuff on the bottom. It doesn't look great, but I guess I won't misplace the wrench either. Thanks again, Nick, for all of your help! It was a true pleasure to speak with you and I greatly appreciate the level of customer service that you provided. Keep up the great work!

## Questions & Answers

**Q: What contaminants can be removed by the system?**
A: Sediment are particulates, physical things not in solution. Like sand, dirt, rust particles... things like that.

**Q: Will the system drop water pressure?**
A: I don't. You will start dropping pressure as the filter clogs up. If that happens just have it clean itself more frequently. My filter doesn't backflush all that well so every few weeks I go down and give it some good taps while it's backflushing to really get it cleaned out

**Q: Does this filter get rid of the smell of sulfer**
A: NO. It's a sediment filter. It will remove sediment from your water.

### ⭐⭐⭐⭐⭐ A+ product and service!
*by R***K on July 14, 2024*

I've had this filter for about two years and it has performed flawlessly. I used to get a lot of sediment from my well, but now it all gets stopped by the filter. I clean it manually a few times per year and have it set to auto-flush every 60 days. Installation was a breeze. I had a plumber replacing an old boiler at the same time, so I did the PEX-A setup with the spin-down, fine sediment and carbon filters The PROS: Very solidly built with sturdy brass top fitting where the water goes in and out. The acrylic bottom is easy to remove with the tool and goes back together easily. The filter is stainless and easy to wash off in the sink to get the particles that auto-flush misses. The customer service is the BEST! Recently I spoke with John about filter size since some of my drip emitters are clogging. Calls are answered promptly by a knowledgeable staff who offer advice, replacement or whatever you need. I had a very small leak in the bottom of the drain valve and I received the replacement within three days. It's impressive when a company spends the time and resources to help its customers after a sale since it is definitely not the norm. The CONS: The auto-flush timer is poorly documented (as of 11/2022) so I had to call customer service a few times. This is an add-on at the bottom of the filter canister where the flush valve is located. There is no control over when it flushes - it is initially set the the time you make the setting, so if you program it a 10 am that is its schedule, but over time it seems to trigger later and later till finally you have no idea when it will trigger a flush. This is a minor issue since it does work periodically even though you never know exactly when. TIPS: I pinched and damaged the sealing gasket one time when I put the unit back together. Since you are basically out of business when this happens, I suggest the company include an extra gasket with the kit. At the time, they were out of stock so I had to find a replacement online. Be sure to use silicone plumbers grease on the gasket so it will go on and off easily and don't overly tighten. I found twisting by hand till it is firmly in place with no leaks is enough. I highly recommend this product and company.
