This 3-filter assembly was purchased
This 3-filter assembly was purchased to install in our Airstream Caravel 20 FB. It works perfectly. What I had to find out could have been specified in the instruction manual. The kitchen water line on our camper was easy enough to disconnect; however, the 1/4-inch poly water line did not come with the fittings to add the filter assembly into our camper. What were needed were a male and female 3/8-inch compression fittings with a 1/4-inch compression ring and nut. The Shark Bite-brand fittings that APEC included were high quality fittings, but did not fit our application. A visit to three hardware specialists led me to the correct parts. All is well and we are delighted with how this assembly fit perfectly under our kitchen sink.
