Good quality components and instructions

Good set up instructions for the most part. Only 2 things were wrong but it was because they upgraded the components and the correct way to use the new ones was obvious.

Not as clean water running as with old one

I don't know what's the reason, but water testing devise shows level 0. 32 on our new filtering system. The old our system showed 0. 06 when it was new. May be with the time the measurements will show lower
