Geekpure 20 Inch Clear Whole House Water Filter Housing with Wrench Bracket -4.5" x 20" - 1" NPT Brass Port (4)

I installed these 4.5"x 20" filters as a whole-house filter system. I added a sizable UV filter also.The label list a Max operating PSI of 90. Then it says, if it exceeds 80 PSI, then a pressure regulator must be installed. The Label is surely confusing to most. I installed 3 pressure gauges at 3 key points on my system. My starting pressure is 65 PSI then after the 4 filters it drops to 60 PSI. This is normal because of the lost pressure within the filters. After my 4 filters and the UV light, my final existing PSI is right above 60 PSI.The filter housing is a 1" brass Female housing. I read all the reviews that talked about the leaking. I did not use pipe tread. I used pipe dope and brushed it on then installed it tight. I let the pipe dope cure for 2 days, then I turned the water on. No leaks after two weeks of running. Looking at the threads I took the approach of sealing the threads by using gooie pipe dope.Overall, the filters are solid. I will modify my system so I can add Unions between each filter, and I will add a drain line after the UV light.Planning + Layout is important for a smooth installation.The red pressure release buttons on the top of the filter housing can be a challenge to sit watertight. I had to call customer service to replace two of them.Customer Service was Excellent! They will make it right and they're on point with communication + follow-through.

I can offer one priceless tip; use teflon tape, and don't be stingy with it. I built a 5 stage with ancillary RO and softening for every drop coming into the house. I used teflon pipe thread sealant in a tube. Don't. I had to rebuild it, I had so many leaks. With tape, it's all good. The fittings are huge, and can probably take more torque, but I'm always careful.

Just finished building my home system. Let's you see what's going on inside the system. Also showed me I had a loose piece of plumbers tape I needed to remove. Two of the pressure valves leaked initially, but unscrewed them flipped the rubber washer over and they stopped. Other fallback would be to just tap the hole and plug it with a brass 1/4 npt plug. Great price and like the system.

Just like others have said - the manufacturer processing doesn’t have the brass inserts in correct alignment. When putting these together with another, they look crooked and awful. Would be ok if you are doing just one. Really upset me - because I only plumb with perfection. And this messes up the entire mechanical room. If you are sloppy - go ahead and get it.

Getting to install my 3-stage whole house water filter now and discovered when more than filter housing are connected together, they start to creat an upside down arch. Aside from bowing filter houses, install is going ok so far, I’ll have to tweak the copper pipe a bit to get the pipe back into square. So if anyone plans to install 2 or more will need to be prepared for this issue. I can’t test for leaks yet as I’m still waiting for a few more parts to arrive then i can finish this and see if any of the filters leak. I will update my review. I included some pictures of the filters mounted.

I bought these on a recommendation. Quality looked good so I was not worried. Overall the install was ok. I have to do it twice for the following issues. DO NOT use Teflon tape as the only sealing method on the inlet/outlet threads. The threads seem to be off or cut not the best so you WILL have leaks. What worked for me is I used a brass 1" npt 2" nipple to connect the housings together. I coated the first 1/2" of the nipples with ptfe thread sealent https://www.amazon.com/Rectorseal-23631-Brush-Thread-Sealant/dp/B0002YPAFY/ref=sr_1_3?crid=2T49GIDA7O6C7&dchild=1&keywords=pipe+thread+sealant&sprefix=pipe+thread+s%2Cautomotive%2C182&sr=8-3 This worked good to get it to seal, I used a copper sweat to 1" adapter and used the same sealant. I have not had any leaks since then. The second issue I have had is one they are installed I keep getting leaks from the O-Ring around the cannister housing. I have checked and re-checked to make sure they where clean and seated correctly. I was about to return then when I did one last thing to try to fix it. I took the housings back off and coated the O-Rings with food grade silicon lubricant. I have used this on other O-rings around potable water and so I figured I would give it a try. https://www.amazon.com/gp/product/B000DZFUPC?pf_rd_r=EQJQYA353A71QK492Z0C&pf_rd_p=edaba0ee-c2fe-4124-9f5d-b31d6b1bfbee So far this seem to be working. Give a coat to them and insert them into the groove and them do one more coat on top of the ring to seat into the top housing. So hopefully this works or I WILL be returning and updating this review.

the pros and consconsbracket to mount housing not rigid enough for weight but worksconnecting multi housing hardware not includedok the prosusing a combination of pipe dope heavy duty teflon tape followed by another layer of pipe dope made a good seal with cpvc nipples 1" mnpt also have used brass in the past as well same seal required tighten fully torqe as far as possible more threads in the betterdo not use tape aloneor pipe dope alonedont be cheap on these pro pipe dope and grey ptfe tapeon the seal inside the housing grab a tube of the clear food grade oring lubethe housing is strong and seals well works as advertised im very happy with the resultsif there is a better way to link these please post it
