Filters for your Water Heater Shield are a critical component to protecting your water heater from the damaging effects of scale. These filters reduce dirt, rust, silt and sediment as well as provide a thin protective layer on your heaters element and other metal surfaces within the water heater. To maintain protection, these filters need to be changed every 6 months or when 10 psi of water pressure is lost (gauge included on the Water Heater Shield).
Pack includes 4 replacement filters, replacement O-rings and new lubricant
Change every six months or when 10 psi of water pressure is lost
Relieve pressure on the system by turning off the water source and opening up a faucet in your home (hot water and cold water spigots)
