Producto de alta calidad
La agua en Tlaquepaque no es de alta calidad. Hice limpiar el tinaco e instalé los filtros en la entrada al tinaco. La agua es notablemente más clara.

With the iSpring system you get good value & product support.
Waited to review until installed for over a month. My system is on well water with a fine clay sediment issue. So far everything is working well. I rebuilt my entire old system. The first filter is the iSprings WSP50 spin down which I can switch out the screen size From 50micron to 1000m & 3 more sizes in between. The spin down cleaning feature works great and is very convenient.Next is my old 22" bag filter (20m). Then the iSpring WGB21B 2filter unit ( Again you have various choices of filters to use depending on your situation) I put guages at each end of all these filters and have only a1 PSI drop after a month of use. I called Don at iSprings with a few questions and received excellent service. He even called back a few days later to check up. All 3 units from iSpring are well made and easy to install if you have some DIY skills. When placing the copper reducer on the plastic filter housing use at least 6-8 wraps of high end plumbers tape. Carefully tighten fiitting to the last thread; this should not leak then. Try to solder as much as possible before screwing into the plastic filter ends. If unavoidable wrap wet cloth aroud joints of copper and plastic before soldering.
