    A:  Good evening, This unit does not "require " renewal of the disposable part. This is a heavy duty made part so depending on usage or if any damage is done would determine if replacement parts are needed. Also, as an option, you can clean it as well. If a replacement is needed, you would need to purchase it online through Home Depot's website. We don't sell replacement parts in any of the stores. Thank You,

      NOT an FRL
      This is the filter and regulator only. There is no “L” (which stands for Lubricator)

        While the unit was straight forward to install the regulator...
        While the unit was straight forward to install the regulator will bleed off pressure constantly until the line pressure is reduced during use. This causes an objectionable amount of noise. Otherwise the unit works fine.
