"...From experience, the PRV port will erode away. Install was simple and fast as my plumbing was copper lines with coupler connections...." Read more

Customers are satisfied with the pressure loss of the water filter. They mention that it allows for minimal pressure loss with the filters in place, and there is no drop in water pressure. The pressure relief valve is a nice feature, and the vent button to relieve the pressure works well.

22 customers mention15 positive7 negative

Customers are mixed about the size of the water filter. Some mention that bigger is better, it fits perfect in their old housing, and the filters are large and do not get clogged very fast. However, others say that the cap is an odd size compared to other canisters, the filters can be hard to change, and that the o-rings themselves are too large for the housings.

"...They're doing their job and have stayed right in place since I pressurized the system. Water now tastes so much improved from before...." Read more

"...The filters are large and therefore do not get clogged very fast...." Read more

"These filters are very big and heavy, especially if it leaks the first time - then you'll need to pick it up with a wet filter inside while trying..." Read more

52 customers mention15 positive37 negative

"...Had to use liquid pipe thread sealant as tape just leaked even after removing and retapping multiple times...." Read more

"Good and strong housing however it does NOT come with a wrench or a mounting bracket… really useless without the bracket because this is very heavy." Read more

17 customers mention0 positive17 negative

Customers are dissatisfied with the holes in the potable water filter. They mention that the mounting holes were not threaded, the housings are not threadable to accept screws, and it does not come with the mounting screws or information on which ones to uses. Some customers also mention that there was a relief valve leak and the screw was apparently loose.

"...I have to agree with the others, I wish the mounting holes were threaded and came with new bolts. Over all, I highly recommend this product." Read more

"...Second problem is the 1 1/2" pipe threads are over cut or not tapered as a pipe thread should be...." Read more

"...These fittings were tricky to find as I had to go to a plumbing supply store to find them...." Read more

Big Blue Works but

Big Blue Works but
Purchased this 20” Big blue Pentair filter as we live in an area that constantly has issues with dirty or brown/yellowing water. The filter is missing the media or filter cartridge. Also it’s missing the mounting kit and screws. I don’t know which screws I used but length were 1 inch and were flat tip. I wished they sold with all parts even if price was higher as I wasted time ordering them and some will have a hard time finding the correct screws for the installation. Why can’t they just sell you a complete set? Had to use liquid pipe thread sealant as tape just leaked even after removing and retapping multiple times. I hope this review helps others only time will tell if this product will help with dirty water. Not sure how long it will last but will add a pressure gauge to it soon as didn’t find any locally.

5.0 out of 5 stars So far works great!
Reviewed in the United States on July 13, 2013
I purchased a home with an undersized (2 7/8) whole home water filter. My well water is pretty good, but it has sediment, iron flakes, and has a slight sulfur dioxide smell. I was using 2um carbon filter from WM or HD for about $5 each, but they would clog up in ~2.5 - 4 weeks. I decided to upgrade and install a Dual BB system with a sediment pre-filter and a carbon block main with pressure gauges in between to judge filter life. Based on the smaller filter's performance I think sediment is my larger problem, because it tended to clog prior to the carbon's ability to remove the SO2.

I went with a the Pentek R30-20BB Pleated Polyester Filter, because it is supposed to be reusable with a quick rinse. I haven't had to rinse it yet so I can't say how well it works after rinsing. There were many complaints that the Pentek EP-20BB Carbon Block Filter reduced system pressure by ~5 PSI. My pressure tank runs between 50 psi to 32 psi and to be honest I don't notice the pressure drop at all. My well pump is rather quick and only takes ~30s to raise the pressure back to 50psi. I suspect that's masking the filter concerns others had.

The installation was pretty straight forward. I'd recommend MAP over propane for soldering as I could finish a joint with ~15s of heat. I would also highly recommend a good heat shield. I had to solder some joints next to drywall and my heat shield was able to withstand all that heat without transferring any of it to the drywall. It wasn't even warm.

My only complaint is that the filter housing doesn't include a wrench. I was able to hand tighten them, but I'm sure I'll need a wrench to unscrew them. I also had to order a third filter housing as one of the original ones had broken tabs which hold the filter. The return and refund process was easy and quick. No complaints there.

3 month update:
Everything is still working great. At 3 months I haven't noticed any pressure drops due to filter clog, but we've started to notice some SO2 smell in the water. I pulled the pre-filter and washed it off. The tank had sediment in it and it was clear the filter was doing it's job. I pulled the carbon filter and I was surprised by how clean the tank and filter are. I couldn't see any sediment in the tank or on the filter. I decided to rinse it just because it was out.

My plan is to keep using the carbon block until the SO2 becomes too bad to bear. I think the pre-filter still has another 6 months in it before I have to rinse it again.

Works great when you finally get it installed. It is pretty heavy and probably oversized for most homes.

Please note it doesn’t come with mounting bracket or adaptors for the 1” NPT.

Pros: you don’t have to worry about losing water pressure for a regular family.
