DuPont WFPF38001CA Universal Valve-in-Head Whole House Water Filtration System, New Version

So just like a lot of people said, this thing leaked a bit at first on the water output. BUT!!! I gave it a few extra wraps (8 - 10) of plumbers tape and no leak. Holding solid and I have my water pressure back most importantly.I'd say for the price it is worth it. We will see. The flow rate is only 5gph and i like strong showers.... so I may add another one of these to the mix or upgrade. But if you don't mind the average shower, nice pressure for water and overall a great setup, this is the way to go. I'll be adding a pressure gauge to the output at some point to monitor it. Will buy again however!

This is a pretty good system with a few minor installation/set up issues.First off, I disagree with the people who said their flow rates/pressure was significantly reduced. This may very well be true if the filter is extremely dirty/clogged but with a clean(ish) filter I've noticed no difference and I have a very old well pump and also installed a water neutralizing filter at the same time as this.The installation process was fairly easy. I had a plumber (my father) install it and it didn't take too much time. The mounting bracket (sold separately) is pretty necessary so be sure to purchase that. We had a few leaks the first couple of times we put it on (because we were trying to be careful not to overtighten and break the plastic housing (even though it looks like very solid plastic.) We finally just put some pipe dope around the threads and the leaks went away. You must definitely use some silicone grease on the o-ring inside the filter housing to avoid that leaking as well so purchase some of that ahead of time.Hire a plumber to install it (most towns/states require it for code issues) and you shouldn't have any issues and shouldn't spend too much on the plumber!I'd definitely buy it again and look forward to many years of clean whole house water!!

I bought this because I believe there is a break in my water line and sediment is getting into they system. Since it's winter, it could be awhile before I can dig up the line to find the problem, so this is a temporary solution. I looked into reverse osmosis, UV purifiers, and various other filters. The best systems are reverse osmosis systems that filter up to 1/1000 of a micron, which would get rid of virtually anything that would make you sick -- sediment, protozoa cysts, and bacteria. However, those systems are either point of use (on top or under the sink) which won't protect my equipment from sediment and I would have to purchase multiple systems -- one for every sink that kids might want to drink out of -- or they are MASSIVELY expensive. UV systems only kill the bacteria and don't get out whatever nasty stuff might be getting into system and jamming up my appliances and/or my kidneys (yes, kidney stones can be caused by crud in your water).This is just a sediment filter. The positives are that it's very cheap, the built in valve means you don't have to turn off the water to change the filter, and because it takes a standardized filter size, you have a choice in filters. This means you can get a filter for it that filters down to 5 microns, which is sufficient to take both the sediment and the protozoa cysts (Giardia) out of your water. However, it still won't take out bacteria. If you are worried about bacteria, that means you either still have to buy a UV purifier, or in lieu of that, still boil your water if you have a bacteria problem. If you don't have a bacteria problem, you're golden and this filter is all you need.Cons: Doesn't filter out bacteria. Also, you really really have to screw the body on tight tight tight with the included "wrench." The most minuscule gap will make it leak. They probably could have designed that part a bit better with a nice big rubber gasket, but they didn't. So put some muscle into it. Also, because the lid is plastic, it took a LOT of pipe joint tape and sealant to keep it from leaking. This takes a 3/4 inch threaded pipe on both ends. You have to buy your own adapters with a male end and a quick connect end if you don't want threaded pipe.

Everything was great about this but after 2-3 years it starts leaking, basically have to buy a while new unit since it doesn't come with any extra o rings or options for it.

I found this product to be perfect for what I needed. I am using it to filter sediment out of the water before it gets to my washer. This product DOES NOT LEAK. I took a chance on this product because of its price even though other people have had issues with it. Well.... I think it is likely user error. I used a hefty amount of teflon tape and snugged the threads up tight and have had no issues. To anyone questioning whether this product is right for you just buy it. For under $20 for a solid product you cant go wrong. Just do yourself a favor and do like 10 wraps of teflon tape and you should be good to go!

Beware!!!!I purchased 3 Dupont Whole House Housings/Cartridges in 2015 through Amazon. They work great. I have them in line with decreasing grades of filtering so that the smallest particles are trapped in the last filter. However, our water is extremely full of sediment and the rust/ore left behind is difficult to clean. I am using a cleanser that is strong but I want to clean the cleanser out before I put the cartridge in and put it back on line. Thus I wanted to purchase the bottom clear plastic part that screws into the head assembly. So I purchased this unit knowing that I would use only the bottom part of it to slip in while I cleaned the one replaced. Unbeknownst to me, they are NOT compatible. They no longer sell the units I purchased in 2015!!! The new units have larger threads and do not seat properly in the old units and water will spray everywhere when you open the water supply. I was not happy that there was NO explanation on the packaging that they were not compatible , They are the SAME model number!

This is a very good filter system. Works great!
