Hot Water Sediment Post-Filter Systems

Ideal for homes with tankless water heaters, the Pentair Hot Water Sediment Post-Filter System reduces sediment buildup that is often associated with heating elements. This system traps sand, dirt, dust, and other debris by suspending solids as small as 5 microns that may precipitate out during the heating process of water. This means you can reduce clogged showerheads and faucets and improve your water pressure.
  • Reduces clogging that occurs in showerheads and faucets as a result of sediment coming from your tankless water heater
  • Two unique models to choose from to meet the demands of your home based on your home size (number of bathrooms)

Benefits of a Hot Water Sediment Post-Filter System

The nature of tankless hot water heaters causes the water to heat up instantly which can cause the water to boil and in turn precipitate out suspended solids that may be present in the water supply. The combination of a 10-micron filter and glass-reinforced nylon housings create a system that is efficient and resilient. The high-temperature filter housing is an economical alternative to stainless and carbon steel housings.

  • Can withstand water temperatures of up to 160-degrees Fahrenheit
  • Housings constructed of glass-reinforced nylon
  • Includes a 10-micron filter cartridge to filter sand, dirt, sediment and other debris
