Two 5 micron precipitating filters (104017) and four 5 micron carbon pre-filters (101009) worked perfectly. A built-in 10" GAC (granular activated carbon) post-filter (560010) limited the water from the facet to just drip off the facet. Yes, the pressure in the tank was set to Watts recommendations. Do not install the GAC 10" Inline Post Filter right after I received it as I just replaced it when I last changed the other filters. I am ordering a kit because the other filters needed replacing. So it's about six months It's been a while since I received the filter and it had to be replaced.It was only later that I found out it was defective.I called the seller and she said she would work with me to resolve the issue but despite numerous Attempts to contact her, nothing more was heard from her Built in post filter GAC.
