Product review (1 stars): Come on, Amazon, do your homework. You get an "F" for this one.
The problem with this thing is that the wide collar at the top prevents the lock nut on the copper 1/4" water supply pipe from making contact with the threads on the receiving nipple on the solenoid valve. Remember that on this type of (somewhat) flexible copper tubing supply you must use a compression washer on the inside of the lock nut or you can't seal the tube running through the nut. The compression washer inside the nut takes up too much room, so the threads on the nut don't reach the valve nipple and you can't tighten it down.
I finally used the thin, black plastic screen type of insert filter which has a thin collar and *wallah* I was done in 1 minute and 45 seconds.
Not worth paying shipping back to the supplier.
Amazon, you failed on this one. Do your homework. You are rich, you can afford it.
