what country made in?

They’re made in Taiwan per the printing on the box which the tank arrived within.

4 gallon okay in place of 3.2 gallon tank

Yes I bought the 4.o gallon unit and it works fine. I checked the pressure in the tank and had to pump it up to 8.0 psi for my system.

Will this work with a watts WP-4V and similar systems?

It is a universal unit and will work with all RO systems. It may require an adopter based on tube size. Thx

has anyone checked their stored water for leeching chemicals?

i have had my water checked for LEAD recently, no issues
