This unit with check ball is what I wanted. You shipped it out quickly.Would recommend you to anyone. Thanks
I could not use the sanitary filter type units because I didn't have enough clearance to install them. This Polylok Filter system worked great because i could glue the bracket on first and then slide the main body of the filter unit onto the glued bracket. I am very pleased with the unit.
Have not installed it yet but expect it to work as claimed.
