Pentek SW-2 Standard Housing Wrench

• Perfect for loosening a ""stuck"" filter housing

I had one other wrench that I had for a long time. I wanted a backup wrench. The first time I used this wrench, it cracked halfway around the ring. I was hardly applying any force on the handle. I then took my old wrench and took the filter housing off with it. The new wrench is useless. I have some plastic molding experience as an engineer and this plastic was either molded incorrectly or is the wrong grade of plastic.

I purchased Culligan HF-360A Whole House Sediment Filter and thought I needed a wrench... but one came with the filter. This one doesn''t say Pentek anywhere on it, it looks generic and it''s probably Chinese junk. It also feels flimsy and as others pointed out having more than one is probably a good idea. I bought several pretty cheap rubber strap wrenches and they not only work better but they won''t break when you''re applying some pressure... plus you can use them for other things like an oil filter. Sorry, I just dislike tools that only have one purpose in life and are not built to last so that''s why it gets only 3 stars... if it works fine changing a filter every month then I would be terribly surprised. I have a collection of various sizes of water filters I''ve used over the years in different homes (based on the unique water problems for each), and from several travel trailers, and I have never been able to get a tight filter off without one of these types of wrenches slipping or breaking and causing me some pain and lots of expletives. Do yourself a favor and buy a strap wrench! However, if this is what you want I paid a little under 4 bucks for it with free shipping so the price is right.

I bought one of these and it broke almost immediately. It broke so quickly i could not even get the housing off of my filter.

So I bought 3 more and only after they arrived, did I try again.

What I learned was that if you put Vaseline on the O-ring as well as the threads of the housing unit, the case goes on much easier, you don''t have to make it as tight and it comes off much easier in 6 weeks or so when it''s time to change the filter again.

Since learning that trick, I have not broken another, however, i am ready, just in case!

I give these 4 stars due to the durability issue. It looks big, thick and heavy... but is easily broken.

That said, i would recommend this, just buy 2.

I used this wrench to remove the housing of the counter top water filter (Watts model CT-1). I had tried everything and failed to loosen the filter housing in order to change the filter. The wrench did help me to get the job done though it was one size larger than what it needed. The product has good quality and price. Service is excellent.
