    • Perfect Fit
Style: System (10 Inch x 4.5 Inch)
No need to replace base of unit. Old filter carrier developed a leak. I just removed screwed out old, placed a new filter in new and screwed it back in. Perfect fit.

    • Good Water Filter
Style: System - Clear (10 Inch x 4.5 Inch)
The unit seems to be well constructed. Once installed, it works well, with no noticeable decrease in pressure or flow. I used a male pex nipple on both sides of the filter, and pex everywhere else. That makes installation pretty easy. The filter housing fits well, no leaks. Just make sure you have it straight when you start. I plan on putting vaseline on the o ring at each filter change. The only issue I had is with getting a good seal where the male fitting enters the filter. Just use lots of tape and tighten it a lot. I probably didn't tighten it enough the first time because I was afraid of breaking it. ... show more

    • Great price, seems to be sturdy
Style: System (10 Inch x 2.5 Inch)
I’m using this with a sediment filter for a gravity flow rainwater system. It didn’t need to stand up to pressure so I ordered the least expensive one I could find. It’s nice that it has an air purge button and comes with mounting bracket and wrench for the housing. The inlet and outlet are 3/4 NPT so I did have to reduce it down for my application. Overall a great product. ... show more

    • You need to use LOTS of teflon tape and 2 tries, but finally got it water tight (I hope!)
Style: System - Clear (10 Inch x 4.5 Inch)
When I first installed this, there were leaks on both of the 1" NPT connections. I had used stainless steel connectors, but thought maybe the threads were not malleable enough and did not provide a good seal against the brass inserts on the filter housing. I swapped for brass connectors and 7-10 turns of GOOD QUALITY THICK Teflon tape, as well as some pipe dope for good measure, and got a good seal with no leaks. Then the next day, I could see water dripping from the 1" input side. Took it apart again, clean the female and male threads, more tape and more brush on pipe sealant. No leaks yet, but will report back if that changes. Given all the bad reviews on leaking problems, I am worried there is something wrong with the design of these things. I do a lot of plumbing work and this is the first time I have ever had a leak from NPT threaded connections. As far a good things, I do like the clear housing version because I can see when the filter needs changing. But the initial leaking does have me concerned. EDIT: 3 months later and no leaks. Really love the clear housing because I can see the filter starting to turn brown from filtering junk out of the water. ... show more

    • Great filter housing
Style: System (10 Inch x 2.5 Inch)
I bought this to replace my previous one which had begun to leak. It was easy to install, and so far, no problems.

This is my first whole house water filtration system. This is the smaller size I0” long. We have excellent water flow in our two bedroom home. It’s only been 18 days since I installed it on our mobile home hooked up to city well water. The filters are pure white before use. Look how much sediment it’s trapping! I included a picture of one of the 5 micron filters in the 4 pack I purchased together as a money savings deal. I recommend you also go that route. I decided to install a filter because of our water heater having heavy amounts of sediment inside after purchasing the place August of this year. I was also wanting to protect the valves in all our new appliances from damage. I think of how this sediment was getting all over me taking a shower! I knew there was a degree of sediment in any tap water. But not this much! I can’t say how much I highly recommend this filter. It’s a very reasonable price for the water filter and 4 pack of filters. Sad to say all the copper hardware cost more than the filter and cartridges. But I wanted to get away from using galvanized pipe. Sealant tape is supplied and a replacement pressure release valve rebuild kit. A canister wrench is included with the kit. Follow all the instructions provided. Use plenty of the included sealant tape especially at the fittings on the filter. I had to redo because of skimping. Follow the instructions. They give special directions on tightening fittings. I also carefully made sure the filter is in the shade at all times. A worry I have about sunlight & UV causing growth of some kind in the filter assembly. I highly recommend this filter! ... show more

    • Economical replacement for Pentair water systems
Style: System (10 Inch x 4.5 Inch)
When the Pentair sediment filter cup cracked and leaked at the bottom radius, this replacement arrived quickly from Amazon to fill the gap in my home water supply. It takes the same filter element and the fittings are the identical size. Make sure you use plenty of the included teflon tape to prevent leaks at the fittings. ... show more
