iSpring WSP-1000SL Reusable Whole House Spin Down Sediment Water Filter, Siliphos Helps Prevent Scale and Corrosion, 1" MNPT + 3/4" FNPT, 1000 Micron

I was a little skeptical when I first received this product and installed it ahead of a 3-stage filtration system & UV-light treatment tube, but after a month of use I am impressed with how well this filter works! I made sure to properly tighten & seal connections to prevent leaks, based on other reviewers’ experiences. It does a great job of filtering out sediment and other crap from our well water, and it is very easy to clean.Because of its smaller size, I clean it once a week to ensure best performance and proper water pressure. We have a 1-inch water line and it does handle volume quite well as long as its kept clean. Cleaning takes about 10 minutes total, as I use an old soft-bristled toothbrush and clean water in a bucket to clean it on-site, and the total time includes time to de-pressurize the supply line.This product is very well built and easy to service; I highly recommend it to anyone with a well or questionable water supply. Just be prepared to clean it every 1-2 weeks, depending upon your water quality; but in spite of this, it is worth it when you see how much clearer your water will be.

This is a surprisingly "beefy" little unit - heavy duty glass container with heavy brass top and well constructed filter which is fairly easy to clean. Simple and straight-forward installation which was quite easy (they even provided some Teflon Tape!). Overall, I'm very impressed with this unit so far and will buy another for my camp house assuming I've encountered no problems after 3 months constant use (only been 40 days since I installed this). I installed this unit ahead of my cartridge filters and there is no doubt in my mind that it will significantly extend their life based on the amount of contaminants/sediment it has already prevented from reaching them - UGH!!!. I purchased the unit with the "Siliphos" filter because I have EXTREMELY hard water and the "Siliphos balls" inside the filter are supposed to help reduce hardness. I can't honestly say just yet how effective they are in reducing hardness and scale because I believe this might take some time to truly be effective. I'll update this aspect of my review after 90 days or so use.My only complaint with this unit is that I wish a mounting bracket were included or at least available for purchase to support it. There's no issue if you are installing it in rigid piping of any kind that is properly supported on either side of this unit BUT if that is not the case and one or both sides are connected to flex piping, the installation doesn't appear as neat and professional. I've not experienced any leaks so far, but it is a concern in the back of my mind over time as the piping is already sagging and I'm trying to determine the best way to support it (ie; can't strap pipe directly to the wall because you need room around the filter to be able to use the supplied wrench to remove the filter canister. I'll add some photos of my solution for this (assuming I find one).

Amazing product and customer service. Sean promptly answers questions and provides solutions. The build quality is top notch and I definitely recommend it for anyone needing a sediment filter as there’s nothing like it on the market. Very straight forward install and maintenance.

I ordered the Spin Down Filter with Siliphos and with the Bypass Valve as to deal with my scale problem. The filter itself seems to be working as advertised for the 2-months I have had it. I noticed a vast improvement in shower glass dried spots and increased spray pressure from the dual shower heads. My ultimate test for this unit is to prevent the scale from accumulating on the heating elements of my new hot water heater. That will take time to tell if this filter will take care of it, but I am hopeful from what I see elsewhere. I would not purchase the filter with the Bypass Valve since it is extremely difficult to turn the valves. There is a plastic wrench that you attach to the plastic handle, and then things can go bad quickly with plastic. I broke the bypass valve lever within a few days, but got it back to the "filter" mode and was going to use the filter as if it did not have the bypass valve on it. I received an email from Laurence at iSpring after I registered the warranty and I told him what I had done. Laurence sent me a new replacement head, which is the upper part of the filter. This new filter can be turned but still very tight. I have a fear of breaking this one as well. If you purchase an iSpring unit, I would suggest to go ahead and buy the filter WITHOUT the bypass valve, and just make your own bypass. I wanted a bypass valve in case the filter started leaking, where I could just bypass it until I had time to fix it. I will probably just make my own one of these days, but the filter itself seems to be working great. Just avoid the type with the valve bypass and get the basic filter and make your own bypass.

I purchased the WSP-50SL. Great addition. You can taste and smell the difference as soon as you install it. I also purchased two [Push fit 3/4 inch x 1 inch], one on each side of the spin down sediment filter.Even though they recommend putting the filter as the first stage, I installed my spin down filter “after” the 3 stage whole house filter. I figure it is a final stage filter (50 micron) I can clean easily and notice when too much debris is getting through the 3 stage filter, while will indicate that the filters need replacing. Easy install.

The spin down filter was easy to install before the WGB32BM three stage filtration system. I'm a barely adequate DIY plumber and I had no issues with installation. I'm looking forward to cleaner, better tasting water with no more odors. The spin down filter will help with the large debris.
