After installing Replacement, I learned some tips for those who wanted to save some money by using a "non-standard" or "foreign" replacement part for ANY reverse osmosis system. supply lines in your reverse osmosis system.

If the reverse osmosis tank is pressurized, it may need to be repressurized. When the tank is filled with water it should read at least 40psi. Hope that helps!
