Is it necessary to install a front water purifier

Yes. Pre-filter on the tap water in the secondary pollutants such as sediment, rust, particles, floating matter, microbes and other pollutants can be effectively filtered out before going into the home; secondly, due to the pre-filter filtration, you can avoid the above pollutants on our home water purifier, water heater, shower and other damages, which can extend the service life of the above appliances. So the filtering effect of the pre-filter, both for health and household equipment have great benefits, or worth installing. Pre-filter precautions installed in the indoor room temperature must not be less than 0 degrees, due to the water in the solidification process volume will expand, if frozen, directly leading to the pre-filter piping, filter bottles, etc. burst, so that water leakage occurs. If installed outdoors, there must be anti-freeze measures, if there is no anti-freeze measures may lead to pre-filter freeze cracks, the temperature below zero degrees must stop using the pre-filter. If you do not use the pre-filter for a long time or need to go out, you must close the water inlet ball valve, drain all the water from the filter bottle, and check the appearance of the machine before using it again.
