20"x4.5" Filter Housing - WHB20

Double o-ring on casing brass insert on head assembly= good unit

We have 'hard' water here that leaves spots, plus wife read a report about the various 'things' in the city water supply... so I bought a 'whole house' size filter to go in the water line to the hot water heater (already have a 'one faucet' filter for the cold water at the kitchen sink for drinking and the daily coffee pot) . While installing this filter I learned something... the water lines I installed going to our two yard faucets are all PVC... which use glue to fit the long pieces together and screw fittings in some places... when screwing parts together I have always used Teflon tape on the threads, which works perfectly . The filter I bought has metal threads... and I found out that tape does not work well... so I dug in the bottom of my supplies and found a tube of Teflon paste... I put paste on the threads of the external fitting that connects to the water line, and on the threads inside the filter housing, and screwed the two parts together... solved the problem of the 'drip' that was working its way through the tape covered threads (my guess is the metal threads were shredding the Teflon tape) I doubt I will ever work with something that has metal threads again, but if I do I will know that tape doesn't work well . I just installed the filter, so I don't know the long term results... but the filter housing is well made, so now it is just a matter of how well the filter element works (which is not part of this purchase, the filter element is a different purchase)

Working system

I use this to hold my DI resin in an internal canister for car washing. Holds pressure and vent works well. Seems as sturdy as Big blue branded ones I had before.

Heavy duty and quality made. Simple hookup.

Excellent, easy installation.

Worked great had everything to do the install

Works great, exactly what I was looking for
